一分钟等于60秒，一秒等于多少纳秒

小时=时，英文单词为hour，通常简写为字母“h”。如1小时简写为“1h”分钟=分；英文单词为minute，通常简写为字母“m”。如2分钟简写为“2min”秒，英文单词为second，通常简写为字母“s”。如3秒简写为“3s”除此之外，生活中常用的时间单位（简写）还有：毫秒（ms）、分（min）、小时（h）、日（d）、月（m）、年（y）等。其中1 毫秒（ms）= 0.001 秒（s），1分（min）=60秒（s），1小时（h）=60分（min），1日（d）=24小时（h），（通常情况下）30日（d）=1月（m），12月（m）=1年（y）。扩展资料：在国际单位制（SI）中，时间的基本单位是秒，符号s，在1967年召开的第13届国际度量衡大会对秒的定义：铯-133的原子基态的两个超精细能阶间跃迁对应辐射的9,192,631,770个周期的持续时间。这个定义提到的铯原子必须在绝对零度时是静止的，而且在地面上的环境是零磁场。在这样的情况下被定义的秒，与天文学上的历书时所定义的秒是等效的。参考资料:时间_百度百科

一秒等于1000毫秒，等于10的15次方皮秒。时间是一个较为抽象的概念，是物质的运动、变化的持续性、顺序性的表现。时分秒都是我们常用的时间单位，1秒的时间很短但是很有价值，毫秒则是更小的时间单位。一秒等于多少毫秒1秒=1000毫秒，时间单位秒是国际单位制中时间的基本单位，符号是s。有时也会借用英文缩写标示为sec。时间单位换算1秒=1000毫秒(ms)1毫秒=1／1，000秒(s)1秒=1，000，000微秒(μs)60秒=1分钟时间的换算是所有单位换算中最复杂的。1年等于365天，1年等于12个月，1个月等于30天，这些都是根据地球、月亮公转决定的，不以人的意志为转移，只不过各个国家、各个朝代有的使用太阳历，有的太阴历，还有的阴阳历所导致略有不同。但一天之内的时间细分却绝对是人为的。古代中国1天等于12个时辰（其他国家也是），这跟地支相对应。地支为什么是12个，而不是11个、13个，也不是古代人拍脑袋想出来。天文中，有很多与12有关的数据，比如，木星每公转一周地球公转12周，地球每公转一周月球公转12周。出于这个心理作用，古代人就把一天平分为了12份。但人们发现，1天12个时辰的划分不够精细化，于是便改为24个小时，正好是12的2倍。1天24个小时是英国人发明的，刚好与地球划分为24个时区相吻合，1个时区就是15°。1小时等于60分钟，1分钟等于60秒，这大概是跟9000年前的苏美尔人那里学的。古代需要对士兵分组，需要分地，需要分粮食，为了好分，苏美尔人发明了60进制，因为60可以被2、3、4、5、6、10整除或分组。后来两河流域的巴比伦人在计时上学习了60进制。后来，全人类广泛推广并使用10进制，但人们早已经习惯了用60进制计算时间，习惯了也就懒得改了。1秒再细分的话就采用10进制了，例如，1秒等于1000毫秒。

　　1、1分钟等于60000毫秒。 　　2、毫秒是一种较为微小的时间单位，是一秒的千分之一。典型照相机的最短曝光时间为一毫秒。一只家蝇每三毫秒扇一次翅膀；蚊子二十毫秒振翅一次；蜜蜂则每五毫秒扇一次。由于月亮绕地球的轨道逐渐变宽，它绕一圈所需的时间每年长两毫秒。

1分钟。根据查询时间换算的格式相关资料得知，6万毫秒是1分钟。时间换算格式：1分钟等于60秒，1秒等于1000毫秒，所以1分钟等于60000毫秒。分钟和毫秒都是时间单位。1分钟=60秒，1秒=1000毫秒，运用乘法，列式可得：1分钟=60乘以1000=60000毫秒。

1秒=1000毫秒，时间单位秒是国际单位制中时间的基本单位，符号是s。有时也会借用英文缩写标示为sec.。国际单位制词头经常与秒结合以做更细微的划分，例如ms（毫秒，千分之一秒）、μs（微秒，百万分之一秒）和ns（纳秒，十亿分之一秒）。虽然国际单位制词头虽然也可以用于扩增时间，例如Ks（千秒）、Ms（百万秒）和Gs（十亿秒），但实际上很少这样子使用，大家都还是习惯用60进制的分、时和24进制的日做为秒的扩充。我们在实际使用的电子秒表单位就是秒，我们在火箭或卫星发射中心控制平台倒计时屏幕上会出毫秒单位的数字飞快变换的画面。秒的下一个单位就是毫秒，那两位数是指百分多少秒，1分6秒66，66通常是指66/100秒，而没有厘秒之说，因为它是计时不是长度单位二者表述不同。所以1s(秒)=1000ms(毫秒)。时间单位换算1秒=1000毫秒(ms)1毫秒=1／1，000秒(s)1秒=1，000，000微秒(μs)60秒=1分钟秒的起源汉朝以前，“时”指季节，“一时”相当于现在的一季。一年有四季，所以一年又叫“四时”。汉朝以后，“时”不再表示季节，而是用来表示计算时间的单位了。当时，人们把一天平均分成12个“时”，“一时”等于现在的两个小时，人们习惯把这个“时”称为“时辰”。在一些古典书籍中，我们也经常会看到“时辰”这两个字，有不少人误认为一个时辰就是现在的一个小时，其实这是不正确的。像古代表示夜间时间的“一更天”、“二更天”的“更”就是指时辰，一更到二更，二更到三更都是相隔两个小时。后来，人们又把一天平均分成24份，每份仍用“时”来表示。这时的“一时”就是现在的一个小时，只相当于过去（汉朝以后）“一时”或“一个时辰”的一半，所指的时间缩短了。接着，人们又把一小时分成60等份，每份的时间叫1分，把1分又分成60等份，每份的时间叫1秒。这样，时、分、秒就确定下来了。时间单位换算1、1世纪=100年；2、1年=12个月；3、1月=30天；4、1天=24小时；5、1小时=60分钟；6、1分钟=60秒；

问题一：空气湿度是怎么计量的啊？多少算合适 湿度（RH%）及计算公式：一、湿度定义 在计量法中规定，湿度定义为“物象状态的量”。日常生活中所指的湿度为相对湿度，用RH%表示。总言之，即气体中(通常为空气中)所含水蒸汽量(水蒸汽压)与其空气相同情况下饱和水蒸气量(饱和水蒸气压)的百分比。 二、湿度测量方法 湿度测量从原理上划分有二、三十种之多。但湿度测量始终是世界计量领域中著名的难题之一。一个看似简单的量值，深究起来，涉及相当复杂的物理―化学理论分析和计算，初涉者可能会忽略在湿度测量中必需注意的许多因素，因而影响传感器的合理使用。 常见的湿度测量方法有：动态法（双压法、双温法、分流法），静态法（饱和盐法、硫酸法），露点法，干湿球法和电子式传感器法。三、绝对湿度和相对湿度、露点湿度很久以前就与生活存在着密切的关系,但用数量来进行表示较为困难。对湿度的表示方法有绝对湿度、相对湿度、露点、湿气与干气的比值（重量或体积）等等。 绝对湿度是指每立方米的空气中含有水蒸气的质量。 相对湿度（Relative Humidity，缩写为RH）是指水蒸气在空气中达到饱和的程度，饱和时为100%RH。当绝对湿度不变时温度越高相对湿度越小。当空气中的含水量没有达到饱和状态，实际含水量与饱和含水量的比值就是相对湿度。相对湿度达到100%，水就不会再自然蒸发了。温度不同，饱和水量也不同，温度越高，容纳的水越多，温度降低了，空气中不能容纳原来那麽多的水了就会出现结露。 凝露是当空气湿度达到一定饱和程度时，在温度相对较低的物体上凝结的一种现象。 湿度是普遍存在的，而凝露只是湿度达到一定程度时的一种特殊现象。四、相对湿度RH%的计算公式计算相对湿度可按照下述公式： 其中的符号分别是：ρw C 绝对湿度，单位是克/立方米 ρw,max C 最高湿度，单位是克/立方米 e C 蒸汽压，单位是帕斯卡 E C 饱和蒸汽压，单位是帕斯卡 s C 比湿，单位是克/千克 S C 最高比湿，单位是克/千克 相对湿度小于30%为低气湿。低气湿低温时可加速机体散热，此时人体中的热辐射被空气中的水蒸气吸收，人感到寒冷，引起毛细血管收缩，皮肤苍白，人体代谢降低，组织内血液循环和细胞代谢发生障碍，引起组织营养失调，发生冻伤。当室内相对湿度小于10%~15%时，空气干燥，使鼻腔、气管、支气管黏膜脱水，弹性降低，黏液分泌减少，纤毛运动减弱，抵抗力降低，使吸入的尘埃累菌不能很快被清除出支，容易诱发和加重呼吸系统疾病。干燥的空气处会导致表皮细胞脱水，角化加快，皮脂分泌减少，导致粗糙起皱、开裂。此外，空气过于干燥还将促使尘土飞扬，使人们的生活条件恶化。 在干燥季节，白喉、流感、百日咳、脑膜炎等疾病的发病率也显著增高，哮喘、支气管炎的发作次数明显增加。其主要原因是干燥空气使流感病毒和致病力很强的革兰氏阳性病菌繁殖速成度加快，并随粉尘扩散，引起疾病流行。 在室温比较适中时，相对湿度的变化对人体的影响比较小。当温度为15。5度时，相对湿度改变50%，对人体影响仅相当于室内温度变化为1度。

%RH是相对湿度的单位。相对湿度（Relative Humidity ），用RH表示。表示空气中的绝对湿度与同温度和气压下的饱和绝对湿度的比值，得数是一个百分比。也就是指某湿空气中所含水蒸气的质量与同温度和气压下饱和空气中所含水蒸气的质量之比，这个比值用百分数表示。相对湿度是单位体积空气内实际所含的水气密度（用d1 表示）和同温度下饱和水气密度（用d2 表示）的百分比，即RH（%）= d1/ d2 x 100%；另一种计算方法是：实际的空气水气压强（用p1 表示）和同温度下饱和水气压强（用p2表示）的百分比，即RH（%）= p1/ p2 x 100%。扩展资料日常生活中的合适数值：夏天，室内相对湿度过大时，会抑制人体散热，使人感到十分闷热、烦躁。冬天，室内相对湿度大时，则会加速热传导，使人觉得阴冷、抑郁。所以，专家们研究认为，相对湿度上限值不应超过80%，下限值不应小于30%。通过实验测定，最宜人的室内温湿度是：冬天温度为20至25℃，相对湿度为30%至80%；夏天温度为23至30℃，相对湿度为30%至60%。在此范围内感到舒适的人占95%以上。在装有空调的室内，室温为20至25℃，湿度为40%至50%时，人会感到最舒适。参考资料来源：百度百科——相对湿度

A：绝对湿度φ：某温度下，样品空气中水蒸气实际含量，叫做绝对湿度。B：饱和湿度Φ：在某温度下，样品空气中所能容纳的水蒸气的最大值（超过这个量，就发生结露现象，在墙壁上就会有水珠出现），叫做饱和湿度。饱和湿度、绝对湿度的大小和取样多少有关，通常没什么实际意义，因此引入相对湿度。C：相对湿度α：某温度下样品的绝对湿度与该温度下的饱和湿度的比值（和样品多少无关，能够客观衡量湿度的大小），定义为相对湿度。α=（φ/Φ）×100%1、α=0，空气完全干燥，不含水。2、α=100%，饱和状态。空气中的含水量和温度有关，温度越高，能容纳的水蒸气也越多。冬天室内温度不要高过24度，湿度指数为50—60的环境最感舒适，而冬天房间的温度太高，室内湿度通常仅为10%-15％RH，在这样的房间呆久了，就会使人皮肤紧绷、干燥上火，感觉不适。所以一定要注意冬天室内通风，即可以保持空气新鲜，有可以让温度不要过高，同时还要注意增加湿度。人体感觉的临界点温度为33℃，低于33℃时有凉的感觉，高于33℃时有热的感觉。当温度为℃、相对湿度为50％、气流速度为0．15/秒（m／s）时、人体处于最佳热平衡状态，感觉最为舒适。适合我国情况的舒适温湿度为：夏天室内温度26－29℃，相对湿度40％－60％冬天室内温度16－21℃，相对湿度30％－50％

相对rh,RH就是相对湿度,(RelativeHumidity)是用露点温度来定义的。(一般情况下,湿度保持在45%RH~65%RH之间最为合适)

%。根据百度教育资料显示，相对湿度的单位为（），A.%；B.C；C.g/kg；D.kg/m3；正确答案：A。相对湿度，指空气中水汽压与相同温度下饱和水汽压的百分比。或湿空气的绝对湿度与相同温度下可能达到的最大绝对湿度之比。也可表示为湿空气中水蒸气分压力与相同温度下水的饱和压力之比。

百分之五十相对湿度

横纬竖经

RH—relativehumidity，相对湿度，一般计算公式中用φ表示。空气中的含湿量d，一般用（g／kg干空气）表示，即1kg干空气中含多少g水分，湿度相同的空气中的含湿量d，与气压、温度有关。在1大气压（B=760mm汞柱），水蒸汽饱和时，即φ=100％0℃时，d=3.78g／kg干空气，20℃时，d=14.69g／kg干空气，40℃时，d=48.84g／kg干空气，相对湿度φ=75％0℃时，d=2.8g／kg干空气，折2.2g／立方米、或0.0022g／升，20℃时，d=11g／kg干空气，折9.2g／立方米、或0.0092g／升，40℃时，d=36.6g／kg干空气，折32.5g／立方米、或0.0325g／升。

%RH指的是相对湿度，数字越大表示空气中含有的水分就越大，湿度就越大；数字越小空气越干燥！！！

在地球仪上,连接南北两极并同纬线垂直相交的线叫做经线,也叫子午线.

相对湿度是绝对湿度和饱和湿度的比值

那个叫经线，标注地理位置时就是叫东经多少度、西经多少度东西的线叫纬线

1、hPa水汽压（曾称为绝对湿度）表示空气中水汽部分的压强，单位以百帕（hPa）为单位，取小数一位。2、℃露点温度是表示空气中水汽含量和气压不变的条件下冷却达到饱和时的温度，单位用摄氏度（℃）表示，取小数一位。3、百分数相对湿度用空气中实际水汽压与当时气温下的饱和水汽压之比的百分数表示，取整数。扩展资料：空气的温度越高，它容纳水蒸气（水蒸气与水汽是不同的）的能力就越高。虽然水蒸气可以与空气中的部分成分（比如悬浮的灰尘中的盐）进行化学反应，或者被多孔的粒子吸收，但这些过程或反应所占的比例非常小，相反的大多数水蒸气可以溶解在空气中。干空气一般可以看作一种理想气体，但随着其中水汽成分的增高它的理想性越来越低。这时只有使用范德华方程才能描写它的性能。理论上“空气中的水蒸气饱和”这个说法是不正确的，因为空气中的水蒸气的饱和度与空气的成分本身无关，而只与水蒸气的温度有关。在同一温度下真空中的水蒸气的饱和度与空气中的水蒸气的饱和度实际上是一样高的。但出于简化一般人们（甚至在科学界）使用“空气中溶解的水蒸气”或“空气中的水蒸气饱和”这样的词句。在这篇文章中我们也使用这些常用的词句。假如饱和的空气的温度降低到露点以下和空气中有凝结核（比如雾剂）的话（在自然界一般总有凝结核存在），空气中的水就会凝结。云、窗户玻璃和其它冷的表面上的凝结水、露和雾、人在冷空气中哈出的汽等等许多现象就是这样形成的。偶尔（或在实验室中人工造成的）水蒸气可以在露点以下也不凝结。这个现象叫做过饱和。参考资料来源：百度百科-湿度

1.快乐的暑假生活英语作文 　　During the summer vacation, my mother took me to Dalian to travel. On the way, I looked out through the window. The mountains in the distance were like giant dragons lying on the ground. The crops in the fields were green and could not be seen. 　　There are some small ponds along the road. The ponds are dotted with several lotus flowers, yellow, pink and white. They are very beautiful. The trees on the roadside are tall and straight, luxuriant and luxuriant, and the colorful wild flowers are blooming. The scenery is very beautiful! After several hours of turbulence, we finally came to the beautiful coastal city of Dalian. How beautiful Dalian is! My mother and I got on the bus to Tiger Beach Park again. There are so many people here! Bustling and flowing, my mother and I can"t wait to run to the sea. The sea is endless. Suddenly, it reminds me of the poem I once learned: fog locks the mountain, fog locks the mountain, and the sky connects the water and the tail water connects the sky. The waves hit the rocks on the shore and splashed white waves, which was very spectacular. The sea washed onto the beach and gently touched the fine sand on the beach, occasionally bringing up one or two shells. 　　The sea breeze gently blows my cheek. How comfortable! After leaving the seaside, we visited the Polar Museum. There, I saw the polar bear, which was only seen on TV before. It dragged its heavy body and took a leisurely walk on the iceberg; The clever sea lion swam about in the water, and his mouth kept shouting, as if he were saying: "welcome, welcome!" The swaying penguins, dressed in black suits and white shirts, are like a gentleman walking around on the ice. They are so cute. We also visited the bird language forest, the happy theater, and the coral island... The trip to Dalian in the summer vacation brought me a lot of happiness! 2.快乐的暑假生活英语作文 　　Before the summer vacation, my mother said that she would take me to Rizhao to play. Finally, she looked forward to this day. I got up early in the morning, prepared my luggage and went to the station with my mother. On the bus, the guide aunt told us jokes and played CDs. We were so happy that we could not wait to put on our wings and fly there early. When the car got on the highway, it was stuck in traffic and broke down. My happy mood was cooled for half a while. The driver"s uncle was busy for a long time before he repaired the car. In the afternoon, we finally arrived at Rizhao. It"s really a good thing. 　　The next day we came to Rizhao fourth bathing beach. As soon as I got off the bus, I saw the blue and boundless sea. The waves were row by row, higher than each other, like a hungry tiger. Seeing such a scene, I was very afraid. I wanted to go swimming, but now I"m afraid to go. Suddenly I heard someone say, "what a pity it is not to go to the sea." Therefore, I made up my mind to go to the sea. The sea water is very mild. A spray came and made me take a sip of the sea water. It"s really salty. I thought of a fun way: I put the swimming ring in the sea, and I sat on it and let the waves push me. After a while, I was pushed to the shore by the waves. On the shore, I buried myself with a lot of sand, only my head and feet were exposed. It was really fun. 　　This summer holiday is really happy! 3.快乐的暑假生活英语作文 　　I love summer best all the year round, because there is my favorite happy summer holiday in summer. 　　During the summer vacation, we have a lot of free space.

What I like most is playing table tennis. Table tennis is the "national ball" of our country. It is most suitable to practice in the summer vacation. The familiar movements are shown in my mind. Recently, I haven"t practiced for a long time, first because of a cold, then because of the end of the term, and then because I went to the art school during the summer vacation. 　　During the summer vacation, as long as I don"t go to art school, I can play computer, watch TV and read books at home. It"s really beautiful. There are a lot of snacks next to me, so it"s more comfortable to eat and play. However, such days are rare. Under the high-pressure policies of our parents, they are subject to restrictions. Of course, I also know that the fun should be moderate, otherwise, there will be no happiness every day. Therefore, it is reasonable for my parents to restrict me. 　　During the summer vacation, I invited several good students to play football, watch movies, swim or go to the students" homes to discuss some things that everyone likes and enhance the understanding and friendship between the students. It is also something that people look forward to and excited about. 　　Summer vacation summer vacation I love you, just like the mouse loves rice, summer vacation I love you, because of you, let me be more happy! 4.快乐的暑假生活英语作文 　　The summer vacation is over.

When I arrived at Grandma"s house, I just sat down and felt the weather was hot as if it was burning in a fire. As I was fanning the wind, I asked grandma if there were any popsicles at home? Grandma smiled and said, "although there is no ready-made popsicle, you can do it!" "Good! Good!" I jumped three feet with joy. 　　I"ll prepare the materials first: white sugar, strawberry, cold boiled rice, ice cube, short wooden stick, chopsticks, small jar, etc. 　　I started making popsicles. I was excited and nervous. I first put strawberries into the jar, poured boiled water, stirred them with a wooden stick, then put a little white sugar, then put them into the ice cube, and finally put them into the refrigerator. 　　After ten minutes, I opened the refrigerator. Ah! The delicious Popsicle was born. Take out the popsicle made by yourself and insert it into the stick to taste it. Looking at my hard work, I couldn"t help taking a big bite. Ah! The mouth suddenly cooled down, and the faint strawberry fragrance filled the whole cavity. I quickly took it to my grandma and grandpa. After they finished eating it, they were full of praise and praised me for my dexterity. Don"t mention how happy I am! 5.快乐的暑假生活英语作文 　　The story of the summer vacation is like the grapes on the grape rack. There are too many to count. I can"t finish it. Let me pick the reddest and sweetest one and tell it to you!

The lotus leaves all over the pond, you squeeze me and I squeeze you, as if welcoming the tourists from afar. I visited Daguan Park, enjoyed the beautiful Fuxian Lake, watched the Jiulong group waterfall with flying waves, and visited Yunnan Normal University. 　　This summer holiday, I not only went to many interesting places, but also read many books. For example: Robinson Crusoe, the other side of the sky blue, the grass house, the stocking pipi, and so on. From reading, I learned that being a man should learn to love, cherish life, be grateful and never give up when encountering difficulties.

I will leave these happy times in my memory for long experience and careful taste! 6.快乐的暑假生活英语作文 　　Summer vacation is what every student hopes for.

In these two months, you are ready to accept the devil like training of that teacher." I thought: Alas, I thought I would be fine if I was scolded.

In the eyes of adults, there are two sides to society. There are truth, goodness and beauty as well as hypocrisy, ugliness and ugliness. Life has its ups and downs. Why do adults and children think so differently? There is only one conclusion: This is the most fundamental difference between mature and immature. 　　In the vast world, everything has two sides. The rich experience of adults determines that they see things more comprehensively. And children must experience something if they want to mature.

湿度单位是%rh。RH就是相对湿度，是用露点温度来定义的。湿度的名词解释：在计量法中规定，湿度定义为“物象状态的量”。日常生活中所指的湿度为相对湿度。 湿度 湿度，一般在气象学中指的是空气湿度，它是空气中水蒸气的含量。空气中液态或固态的水不算在湿度中。不含水蒸气的空气被称为干空气。由于大气中的水蒸气可以占空气体积的0%到4%，一般在列出空气中各种气体的成分的时候是指这些成分在干空气中所占的成分。 空气的干湿程度，或表示含有的水蒸气多少的物理量，称为湿度。单位体积的空气中含有的水蒸气的质量叫作绝对湿度。由于直接测量水蒸气的密度比较困难，因此通常都用水蒸气的压强来表示。空气的绝对湿度并不能决定地上水蒸气的快慢和人对潮湿程度的感觉。人们把某温度时空气的绝对湿度和同温度下饱和气压的百分比叫作相对湿度。

About Han Dynasty. The Han dynasty followed the Qin dynasty when the Great Walls were built and the Terracotta Army was entombed. In turn it was followed by the Three Kingdoms well known from the classic novel Romance of the Three Kingdoms written in the 14th century and attributed to Luo Guanzhong. This golden age of Chinese chivalry fell beeen the Han and Jin dynasties. Chinese people consider the Han dynasty one of the greatest periods of China"s history. Members of the ethnic majority of Chinese people still call themselves “People of Han”. During the Han China prospered and the empire extended its political and cultural influence over Vietnam Central Asia Mongolia and Korea. Throughout the Qin and Han dynasties China"s most formidable opponent was the Xiongnu (Huns) who from time to time rode south and raided the Chinese cities along the borders. The raids prompted the Qin to build the first Great Walls. For almost 70 years the Han court had to buy peace – which usually lasted only o or three years – by sending princesses of the Han royal family to be married to the Xiongnu king. But when Wu Di (the sixth Han emperor from (140BC – 87BC) took over he had just o things on his mind: strike back and trade. He spent almost six years learning the Hun tactics and 10 years preparing for war. Wu reformed the army by building up and improving the cavalry buying and *** uggling in better breeds of horses from the Huns and from Central Asia (today"s Turkistan). He also adopted new technology from the west to produce better steel for arms. The route to the west also known as the Silk Road opened up trade exporting Chinese silk as far as Rome the world"s other superpower. After the Qin dynasty perishes an item of feather and Liu Bang launched four year Chu Chinese war. Liu Bang in under Xiao Ho Han Hsin person"s under the and so on Zhang Liang assistance has defeated west a Chu overlord item of feather war of in the Gaixia officially proclaims oneself emperor in 202 B.C. decides the dynasty name Chinese the Han Dynasty starts in light of this. Although 202 B.C. Liu Bang only then proclaims oneself emperor but when the history calculates Western Han Dynasty year several in order to perishes the time docking with the Qin dynasty then from 206 B.C. Liu Bang called "the Chinese king" calculates and take October as Chinese great-great grandfather first year first month.

The Han Dynasty (Traditional Chinese: 汉朝; Simplified Chinese: 汉朝; Hanyu Pinyin: Hàn cháo; Wade-Giles: Han Ch"ao; 206 BC–AD 220) followed the Qin Dynasty and preceded the Three Kingdoms in China. The Han Dynasty was ruled by the prominent family known as the Liu clan. The reign of the Han Dynasty lasting 400 years is monly considered within China to be one of the greatest periods in the entire history of China. As a result the members of the ethnic majority of Chinese people to this day still call themselves "People of Han" This is because during this time the Han ethnic group became dominant in China and is still dominant today. During the Han Dynasty China officially became a Confucian state and prospered domestically: agriculture handicrafts and merce flourished and the population reached over 55 million. Meanwhile the empire extended its political and cultural influence over Korea Mongolia Vietnam and Central Asia before it finally collapsed under a bination of domestic and external pressures. The first of the o periods of the dynasty was the Former Han Dynasty (Simplified Chinese: 前汉; Traditional Chinese: 前汉; pinyin: Qiánhàn) or Western Han Dynasty (Simplified Chinese: 西汉; Traditional Chinese: 西汉; pinyin: Xī Hàn) 206 BC–AD 9 seated at Chang"an. The Later Han Dynasty (Simplified Chinese: 后汉; Traditional Chinese: 后汉; pinyin: Hòu Hàn) or Eastern Han Dynasty (Simplified Chinese: 东汉; Traditional Chinese: 东汉; pinyin: Dōng Hàn) 25–220 was seated at Luoyang. The western-eastern Han convention is currently used to avoid confusion with the Later Han Dynasty of the Period of the Five Dynasties and the Ten Kingdoms although the former-later nomenclature was used in history texts including Sima Guang"s Zizhi Tongjian. 参考: en. *** /wiki/Han_Dynasty This article is about the majority ethnic group within China. The Han (Simplified Chinese: 汉族 or *** ; Traditional Chinese: 汉族 or *** ; pinyin: hànzú or hànrén) is an ethnic group originating from China. As the ethnic group forming the majority of the Chinese population it is the largest single human ethnic group in the world numbering over 1.3 billion people. The Han people constitute about 92 percent of the population of mainland China and about 19 percent of the entire global human population. There are substantial geic linguistic cultural and social differences beeen its various subgroups. Thousands of years of regionalized assimilation of various ethnic groups and tribes in China is the primary reason for this diversity within the Han. The Han are traditionally symbolized by the colour red. 参考: for more details: en. *** /wiki/Han_Chinese

问题一：代表湿度的那个单位符号 一般是指相对湿度，符号为 %RH。 相对湿度（Relative Humidity），空气有吸收水分的特征,湿度的概念是空气中含有水蒸气的多少.它有三种表示方法： 第一是绝对湿度,它表示每立方米空气中所含的水蒸气的量,单位是千克/立方米； 第二是含湿量,它表示每千克干空气所含有的水蒸气量,单位是千克/千克u30fb干空气； 第三是相对湿度,表示空气中的绝对湿度与同温度下的饱和绝对湿度的比值,得数是一个百分比.(也就是指在一定时间内,某处空气中所含水汽量与该气温下饱和水汽量的百分比.) ； 相对湿度用RH表示.相对湿度的定义是单位体积空气内实际所含的水气密度（用d1 表示）和同温度下饱和水气密度（用d2 表示）的百分比,即RH（%）= d1/ d2 x 100%；另一种计算方法是：实际的空气水气压强（用p1 表示）和同温度下饱和水气压强（用p2表示）的百分比,即RH（%）= p1/ p2 x 100%。 问题二：湿度应该用什么单位 空气湿度是指空气潮湿的程度，可用相对湿度(RH)表示，它是用露梗温度来定义的。相对湿度是指空气实际所含水蒸气密度和同温下饱和水蒸气密度的百分比值。人体在室内感觉舒适的最佳相对湿度是，49%～51%，相对湿度过低或过高，对人体都不好。 问题三：什么是湿度？单位是什么？ 表示大气干燥程度的物理量。在一定的温度下在一定体积的空气里含有的水汽越少，则空气越干燥；水汽越多，则空气越潮湿。空气的干湿程度叫做“湿度”。在此意义下，常用绝对湿度、相对湿度、比较湿度、混合比、饱和差以及露点等物理量来表示；若表示在湿蒸汽中液态水分的重量占蒸汽总重量的百分比，则称之为蒸汽的湿度。 【综述】 空气的温度越高，它容纳水蒸气的能力就越高。虽然水蒸气可以与空气中的部分成分（比如悬浮的灰尘中的盐）进行化学反应，或者被多孔的粒子吸收，但这些过程或反应所占的比例非常小，相反的大多数水蒸气可以溶解在空气中。干空气一般可以看作一种理想气体，但随着其中水汽成分的增高它的理想性越来越低。这时只有使用范德华方程才能描写它的性能。 理论上“空气中的水蒸气饱和”这个说法是不正确的，因为空气中的水蒸气的饱和度与空气的成分本身无关，而只与水蒸气的温度有关。在同一温度下真空中的水蒸气的饱和度与空气中的水蒸气的饱和度实际上是一样高的。但出于简化一般人们（甚至在科学界）使用“空气中溶解的水蒸气”或“空气中的水蒸气饱和”这样的词句。在这篇文章中我们也使用这些常用的词句。 假如饱和的空气的温度降低到露点以下和空气中有凝结核（比如雾剂）的话（在自然界一般总有凝结核存在），空气中的水就会凝结。云、窗户玻璃和其它冷的表面上的凝结水、露和雾、人在冷空气中哈出的汽等等许多现象就是这样形成的。偶尔（或在实验室中人工造成的）水蒸气可以在露点以下也不凝结。这个现象叫做过饱和。 空气中水蒸气的溶解量随温度不同而变化。一立方米空气可以在10摄氏度下溶解9.41克水，在30摄氏度下溶解30.38克水。 【测量】 湿度计多个量被用来表示空气的湿度。下面列出最常用的： u30fb蒸汽压 u30fb绝对湿度 u30fb相对湿度 u30fb比湿 u30fb露点 用来测量湿度的仪器叫做湿度计。 ▲绝对湿度 绝对湿度是一定体积的空气中含有的水蒸气的质量，一般其单位是克/立方米。绝对湿度的最大限度是饱和状态下的最高湿度。绝对湿度只有与温度一起才有意义，因为空气中能够含有的湿度的量随温度而变化，在不同的高度中绝对湿度也不同，因为随着高度的变化空气的体积变化。但绝对湿度越靠近最高湿度，它随高度的变化就越小。 下面是计算绝对湿度的公式： e m ρw ＝───＝── Rwu30fbT V 其中的符号分别是： e 蒸汽压，单位是帕斯卡 Rw 水的气体常数=461.52J/(kg K) T 温度，单位是开尔文 m 在空气中溶解的水的质量，单位是克 V 空气的体积，单位是立方米 ▲相对湿度 一台湿度计正在纪录相对湿度相对湿度是绝对湿度与最高湿度之间的比，它的值显示水蒸气的饱和度有多高。相对湿度为100%的空气是饱和的空气。相对湿度是50%的空气含有达到同温度的空气的饱和点的一半的水蒸气。相对湿度超过100%的空气中的水蒸气一般凝结出来。随着温度的增高空气中可以含的水就越多，也就是说，在同样多的水蒸气的情况下温度升高相对湿度就会降低。因此在提供相对湿度的同时也必须提供温度的数据。通过相对湿度和温度也可以计算出露点。 以下是计算相对湿度的公式： ρw e s φ ＝───u30fb100%＝─u30fb100%＝─u30fb100% ρw,max E S 其中的符号分......>> 问题四：绝对湿度的单位 绝对湿度的单位就是水蒸气压的压强，千帕、兆帕或毫米汞柱。 问题五：湿度的计量单位是什么？ 目前用来衡量湿度大小的单位尚不统一,有的单位定义不够确切,各有关手册所列湿度的量值互有出人,关于真实气体偏离理想气体的修正向题也没有很好地解决,本文试图对这些问题进行探讨。 : p―湿气体的压力(Pa); ps―湿气体中所含水蒸汽的分压力(Pa); p、s一一与湿气体温度t相对应的饱和蒸汽压力(Pa); p、sL―与湿气体露点温度tL相对应的饱和蒸汽压力(P。); p。―标谁状况的压力,101325Pa; P:―干气体的临界压力(P。); P。―湿气体的临界压力(Pa); 常用温度单位换算表露点绝对 湿度 g/m3体积比 ppmV重量比 在空气中 ppmW相对湿度 (20℃)% 露点绝对 湿度 g/m3体积比 ppmV重量比 在空气中 ppmW相对湿度 (20℃)%℃0F℃0F-70-940.002072.51.640.001-10142.062560159011-60-760.00857116.590.0050324.846020380026-50-580.03123924.20.0210509.2112100772952-40-400.10212779.10.05206818.523100 100-30-220.3013762340.2308636.641800 -20-40.816102063544010458.573000

I hungry reading, in front of me show a colorful changes of the universe, the vast universe far it"s hard to imagine, it"s hard to imagine it"s age is old, no one knows for sure where to begin to end it. On a clear night sky, have you ever seen a across the night sky, faintly visible white light? It is the Milky Way. We live in the earth is in the midst of the Milky Way, and outside of the Milky Way galaxy in the universe, and hundreds of billions of galaxies like the Milky Way, they are collectively known as the "river of galaxies. u2022 I aspire to the universe, it is mysterious, with stars planets satellites and pulse neutron super star and split the night dragged bright comet tail and devour all black hole... u2022 I yearn for is the boundless universe have an alien, what they look like?
