“日”加一画总共可以组成15个字。 1、常用：目、白、旧、申、甲、由、电、曰、旦、田、巴。 2、少用：曱（音“约”义为取物）、甴（古同“由”）、（同“涿”,是涿的异体字）、罒（同“网”，用作偏旁）。

“日”加一画总共可以组成15个字。旧、旦、白、田、申、电、目、甲、由、曱、甴最后四个字就很少人会了。其中两个读音似普通话的“七、缺”，是象声词，形容转动速度很快时的声音。）。“七”的写法也象“甲”，只是一竖只在“日”的头上，丝毫不穿到“日”字里面去。而“缺”字象“由”，一竖只在“日”的下面，也丝毫不穿到“日”字里面去。最后两个字读音“呢诶”，写法分别是繁体字“门”的拆开来的两边，一边是一个字，拆出来左边是“呢”字，右边是“诶”字。也是粤语的象声词，指的是就门开关时的声音最后的四个字字库里都没有。您自己根据我说的书写方法写写看吧。

“日”加一画总共可以组成15个字.旧、旦、白、田、申、电、目、甲、由,这9个大家都会,爱问里这个提问有很多,但采纳的答案我看过,基本都是这9个.还有就是：曱、曱（广州蟑螂的粤语写法,读音“嘎砸”.“嘎”是“甲”从...

二氧化碳灭火剂的特点及灭火机理是：二氧化碳是一种广泛使用的灭火剂，它是无色无味、不燃烧、不助燃、不导电、无腐蚀性的惰性气体。灭火用的二氧化碳是以液态的形式加压充装在灭火器中，当灭火器开关阀被打开时，依靠二氧化碳的蒸发作用，液态的二氧化碳从灭火器喷出立即气化，吸收大量的热量。使气化气体凝结成的雪花状物质即干冰。雪花状的固体颗粒的干冰温度为-78.5℃，具有极大的冷却降温作用。1kg液态二氧化碳气化时需吸收578kJ热量，导致液体本身温度急剧下降，使其冷却。同时干冰遇热后即升华为气态二氧化碳，覆盖于燃烧物表面，冲淡空气中氧的含量。当燃烧区域空气中氧的浓度低于12%或二氧化碳的体积浓度达到30% ~ 35%时，绝大多数火焰会自动熄灭。

二氧化碳能灭火的原因如下：二氧化碳灭火剂是一种具有一百多年历史的灭火剂，价格低廉，获取、制备容易，其主要依窒息作用和部分冷却作用灭火。二氧化碳具有较高的密度，约为空气的1.5倍。在常压下，液态的二氧化碳会立即汽化，一般1kg的液态二氧化碳可产生约0.5立方米的气体。因而，灭火时，二氧化碳气体可以排除空气而包围在燃烧物体的表面或分布于较密闭的空间中，降低可燃物周围或防护空间内的氧浓度，产生窒息作用而灭火。另外，二氧化碳从储存容器中喷出时，会由液体迅速汽化成气体，而从周围吸引部分热量，起到冷却的作用。二氧化碳灭火器主要用于扑救贵重设备、档案资料、仪器仪表、600伏以下电气设备及油类的初起火灾。在使用时，应首先将灭火器提到起火地点，放下灭火器，拔出保险销，一只手握住喇叭筒根部的手柄，另一只手紧握启闭阀的压把。对没有喷射软管的二氧化碳灭火器，应把喇叭筒往上扳70—90度。使用时，不能直接用手抓住喇叭筒外壁或金属连接管，防止手被冻伤。在使用二氧化碳灭火器时，在室外使用的，应选择上风方向喷射；在室内窄小空间使用的，灭火后操作者应迅速离开，以防窒息。物体燃烧有三个必要条件：可燃物、氧气、必要的温度，移除三者中其中一个即可达到灭火的效果，而二氧化碳能用于灭火，是因为：1、二氧化碳在空气中既不能燃烧、也不支持燃烧。2、二氧化碳密度比空气大，能覆盖在燃烧物表面，起到隔绝空气的作用。

1、二氧化碳灭火器适用于扑救A、B、C、E类火灾，不适用于金属火灾。2、A类火灾指固体物质火灾，如木料、布料、塑料等燃烧形成的火灾。3、B类火灾指液体火灾和可溶化的固体物质火灾，如可燃易燃液体和沥青、石蜡等燃烧形成的火灾。4、C类火灾指气体火灾，如煤气、天然气、氢气等燃烧形成的火灾。5、E类火灾指物体带电燃烧的火灾。扩展:二氧化碳灭火器适用于扑救A、B、C、E类火灾，不适用于金属火灾。A类火灾指固体物质火灾，如木料、布料、塑料等燃烧形成的火灾。B类火灾指液体火灾和可溶化的固体物质火灾，如可燃易燃液体和沥青、石蜡等燃烧形成的火灾。C类火灾指气体火灾，如煤气、天然气、氢气等燃烧形成的火灾。E类火灾指物体带电燃烧的火灾。使用方法：先拔出保险销，再压合压把，将喷嘴对准火焰根部喷射。注意事项：使用时要尽量防止皮肤因直接接触喷筒和喷射胶管而造成冻伤。扑救电器火灾时，如果电压超过600伏，切记要先切断电源后再灭火。

I like collecting stamps. I started to collect them when I was ten years old. It"s very interesting to collect stamps. My friends are always sending me nice stamps because they know I would be happy to receive them,so now I have many stamps. I have been collecting 300 pieces of stamps by far and I stored them in 8 stamp albums. I have one set of Olympic stamps. They are so wonderful! Do you know anyone else who collects stamps? If yes, please tell me! I would like to start a stamp collectors" club. And what"s your hobby?

不是，灭火方式有隔离，冷却，抑制，窒息。二氧化碳原理是利用二氧化碳气体排除空气，导致氧气不足而使火熄灭，破换燃烧条件。另外二氧化碳温度低瞬间气化会带走周围热量有冷却作用。所以二氧化碳灭火属于窒息和冷却。二氧化碳灭火器主要用于扑救贵重设备、档案资料、仪器仪表、600伏以下电气设备及油类的初起火灾。 根据二氧化碳既不能燃烧，也不能支持燃烧的性质，人们研制了各种各样的二氧化碳灭火器，有泡沫灭火器、干粉灭火器及液体二氧化碳灭火器。

忽有故人心上过，回首山河已是秋，两处相思同淋雪，此生也算共白头。译文：从故人的心上经过，只留下了一道痕迹，最终回首的时候才发现已经是重峦叠嶂，往事如烟。两个异地的人在大雪飘飘日子里的互相思念着，雪落到了两人头上，也算是一起白头到老了。当时的李清照，初到杭州，无依无靠，张汝舟以赵明诚同学的身份，接近了李清照，对她百般照顾。这个张汝舟是浙江人，早年为池阳军中小吏，北宋微宗年间取得了进士。后来又当了个小官，他花言巧语，取得了李清照的信任。感悟：都要学会接受事实，但今生只会经历这一次，撕心裂肺的痛楚尝一次就够了，你始终要相信有些人不是没有逢场作戏的能力，她只是看淡了世间百态，不会再有逢场作戏的兴趣。做一个温暖的人，感知着这世间所有细微而朴素的美好，不为难他人，也不为难自己，从此做一个寡言，却心有一片海的人，不伤人，不虐己，在这文字中抒发对你的感情，渡心、渡情、渡自己。

我人生中一个真实的考试是在全班面前讲话！想象一下我当时会是多么的内敛当我想到那么多只眼睛全在盯着我一个人。但是我却没有任何其他的选择。首先我写好了演讲的稿子，这对于我来说确实很简单，因为我是一个很棒的“作家”-这也是很让我骄傲的一件事。但是更难得还是在口语上去讲给大家；而不是读（这不被允许）；我需要根据我的记忆来演讲，并且是在那么多观众的前面！当我真正站在台上是我感觉到了这个巨大的挑战，我的双腿在颤抖并且整个脑袋都变空白了。我不知道过了多长时间。我的听众一直在耐心的等待着，一点都不对我着急。终于我回归了，带着艰难的演讲完。对我来说就像过了100年，但是最后我发现我的听众都在为我鼓掌。我做到了！从那一次开始，我对于在很多人面前讲话的恐惧再也不见了。同时我也更加的有自信了，我现在成为了一个很棒的“演说家”。回想当时，我突然明白了在成功的道路上最大的困难就是克服一些恐惧，只要你克服了，就有可能实现最终的目标。很费力的人工翻译啊亲！希望你采纳~~

二氧化碳灭火器灭固体物质火灾、液体火灾和可溶化的固体物质火灾、气体火灾。二氧化碳灭火器是一种具有一百多年历史的灭火剂，价格低廉，获取、制备容易，其主要依靠窒息作用和部分冷却作用灭火。主要用于扑救贵重设备、档案资料、仪器仪表、600伏以下电气设备及油类的初起火灾。灭火器“五大家族”在大家印象中，灭火器外观是红色的，但是近年来市面上有不少绿色瓶身的灭火器。最常见的灭火器有五种，分别是水基型灭火器、泡沫灭火器、干粉灭火器、卤代烷灭火器、二氧化碳灭火器。对于不同类型的火灾，灭火器可不能大小通吃，而要根据场所的火灾种类选择不同种类的灭火器。如果选择不合适的灭火器，不仅灭不了火，还有可能引起逆化学反应，甚至造成爆炸伤人事故。市民生活中最常接触到的，就是水基型灭火器和干粉灭火器。前者适用于扑救易燃固体或非水溶性液体的初起火灾。而后者适用范围广，适宜扑灭油类、可燃气体、电器设备等初起火灾。

不要误入歧途，你知道这句话的意思，这么简单，没必要在分析，先有语言，后又语法，语法解释不了所有的语言现象。你就是知道他是名词或副词，对你理解句子有帮助吗？这样最耽误学习了，你说汉语从来不考虑语法，语法可以作为初学时的工具，不是枷锁。你听听英语电影，好多不按语法来说。

灭火器原理如下：二氧化碳灭火剂主要依靠窒息作用和部分冷却作用灭火。干粉灭火剂主要通过在加压气体作用下喷出的粉雾与火焰接触、混合时发生的物理、化学作用灭火。二氧化碳灭火器原理：二氧化碳具有较高的密度，约为空气的1.5倍。在常压下，液态的二氧化碳会立即汽化，一般1kg的液态二氧化碳可产生约0.5立方米的气体二氧化碳灭火剂主要依靠窒息作用和部分冷却作用灭火。二氧化碳具有较高的密度，约为空气的1.5倍。在常压下，液态的二氧化碳会立即汽化，一般1kg的液态二氧化碳可产生约0.5立方米的气体。干粉灭火器原理：一是靠干粉中的无机盐的挥发性分解物，与燃烧过程中燃料所产生的自由基或活性基团发生化学抑制和副催化作用，使燃烧的链反应中断而灭火。二是靠干粉的粉末落在可燃物表面外发生化学反应，并在高温作用下形成一层玻璃状覆盖层，从而隔绝氧，进而窒息灭火。

您好，很高兴回答你的问题，二氧化碳灭火器主要用于灭火防护高危和敏感的设备和场所。例如，电子设备、医疗设施、化学实验室、机械室等火灾风险高的场所。它还适用于不利于水灭火的场所，例如电器室、服务器房、图书馆等。二氧化碳灭火器也可以用于汽车、航空器和船舶的灭火，因为它不会对设备造成损害或腐蚀，并且效果非常好。在工业领域，二氧化碳灭火器也被广泛应用于石油、化工和危险物品贮存区域的灭火，以及挂钩着高空作业人员的安全设备中。总而言之，二氧化碳灭火器在诸多领域和行业具有广泛的应用，可以有效地抗击火灾方面问题。

　　二氧化碳灭火器适用于扑灭图书，档案，贵重设备，精密仪器、600伏以下电气设备及油类的初起火灾。适用于扑救B类火灾，（如煤油、柴油、原油，甲醇、乙醇、沥青、石蜡等火灾。）适扑救C类火灾（如煤气、天然气、甲烷、乙烷、丙烷、氢气等火灾。）扑救E类火灾（物体带电燃烧的火灾）。　　二氧化碳灭火剂是一种具有一百多年历史的灭火剂，价格低廉，获取、制备容易，其主要依靠窒息作用和部分冷却作用灭火。　　灭火原理　　在加压时将液态二氧化碳压缩在小钢瓶中，灭火时再将其喷出，有隔绝空气的作用；另外二氧化碳从储存容器中喷出时，会由液体迅速汽化成气体，而从周围吸收部分热量，起到冷却的作用。
