The winter vacation started in a true meaning.The following days I called on my old friends,we talked the interesting stories happened in own campus with each other,and we also shard the experience of study with each other.We even talked the unforgettable things among us in the senior year.We also held a party which all my classmates took part in.Those days were so unforgettable that it would in my mind for my whole life.Yes,life was full of beauty rather full of sorrow.It must be so-called that you were lake of eyes which found beauty while everything in your eyes was black. With the Spring Festival nearer and nearer,my family were busy buying groceries.We had a lot to buy,first my father had to buy us new clothes for the coming Spring Festival.On that day we spent a whole day picking over our own favorite clothes and my father"s duty was paying for the clothes we bought.My duty was taking all the shopping we bought all the way home.When I got home,I was so tired that I was asleep in a minute after I got to bed.Although that day for me was too tired to have no appetite for dinner,I was in a good mood because I enjoyed myself with my family. The following days we still had a lot to buy,such as all kinds of vegetables which was not only for us to eat but also for treating our guest,fruits,candies,firecrackers and festival couplet and so on.During those days,all my family led a quite a busy time rather than a cozy time.It was not until four days over the Spring Festival,our family were not as busy as before any longer,especially for me,there was a large amount of time for me to surf the Internet.I would go there to download my favorite songs with my old friends every now and then., Maybe the Spring Festival Eve was the most unforgettable time in the whole year,when almost every family could get together and have meal together.We watched TV together,played cards together,had chats with each other,ate candies and peanuts together and so on.In a word,we all enjoyed ourselves that eve and we didn"t go to bed until 1 o"clock.Until 6o"clocknext morning,according to the old custom,we ate meat dumplings even we didn"t have any appetite for them.After eating them,I was one year old than before. About 8 o"clock,the outside was completely quite after constantly putting off firecrackers for almost a whole night.Little kinds ran here and there with the gift money getting from their parents and grandparents and they could use a small part of their money to buy something they liked. This year was a different year from ever before; there were a lot of activities for old and young to take part in.I took part in basketball team but never had a chance to play in the court.To the contrary,I found I was a complete audience. The following days I visited relatives with my parents one by one,and every time after visited I always too full to eat anything fog such along time.After visiting all the relatives,the days went on as usual.It didn"t take long before I came back to our campus and it also meant the interesting Spring Festival came to an end Back to campus,I sat beside my desk and began the busy life again.Yes,tomorrow was a beautiful day.I was sure what waited for me in the future was full of challenge and that my future was quite brighter than anyone else. 另附 I had a good winter vocation last year.It was colorful.I did my homework and helped my mother with the housework.I also read lots of books.I visited many places with my parents.First we traveled to Yunnan by plane.We spent seven days there.We visited Kunming,the capital city of Yuannan.We climbed West Mountain and visited the Stone Forest.We ate local food and bought wood carvings.Then a week later after the trip to Yuannan.We went to Haebin.Though it was cold,the ice and snow world was fantastic.We also went skiing.It was my first time to ski.The coach taught us how to ski.I learnt very fast.We stayed and skied for about four hours.We had a good time there.My winter vocation was wonderful and I will never forget my last winter vocation九万里风9 2023-07-12 10:09:211

海底通信(submarine communication)

二代测序数据中的PCR duplication是什么,是怎么产生的?
是引物的3"端间相互错配扩增形成的。引物二聚体的出现是必然的,只是或多或少的问题,电泳时看不到引物二聚体带也不代表没有二聚体出现,只是含量低我们的肉眼看不到而已。提高PCR严谨性(包括提高退火温度,降低引物浓度等)可大大降低二聚体的浓度。减少PCR产物中引物二聚体的方法:1从引物自身着手,重新设计引物,这是最根本解决这一问题的办法;2.可能模板有问题;模板浓度过小,适当加大模板量;3.Taq酶,引物,Mg2+浓度可能过高,可降低它们的浓度;4.取你所要加的上下游引物混合后,在100摄氏度下的沸水中煮5分钟,然后迅速拿出至于冰块之上瞬时冷却,这时再加入反应体系当中,引物二聚体就会消失的;理由:引物可能会发生发夹结构,自身环化等结构,在100摄氏度下的沸水中煮5分钟可使引物变为单链,以减少二聚体。不过有人认为在 PCR仪上95度变性5min也同样达到目的,而且成功试过通过延长退火时间也可以消除引物二聚体。5.所配MIX中加5%的甘油或者5%的DMSO,可以增强特异性;6.PCR反应体系的配制在冰上进行,最后加TAq酶,PCR结束后,产物勿放置在室温下过长时间,有人认为室温下有些TAQ酶会将多余的引物合成为二聚体。7.增加循环数;8.降低退火温度后有条带,则应逐渐提高温度,若提高温度的同时产物量减少,则考虑增加镁离子浓度(根据扩增片断长度而定,片段长则相应镁离子浓度应该高一些);9.若降低退火温度,发现还是只有引物二聚体,而且镁离子的浓度在20-25mmol/l没有区别,则考虑 Buffer等试剂没有完全融解、混匀,导致吸取的试剂浓度不对。10. 以上次的PCR产物作模板二次PCR,可以提高引物与模板的特异性,减少引物二聚体,如果两次时间间隔短的话,可以把原产物稀释100-1000倍,如果间隔较长可以稀释50-100倍。望采纳左迁2023-07-02 09:41:571

delicate与fragile的区别
"Delicate" 和 "fragile" 这两个词都可以用来描述脆弱的物品,但它们有些微妙的区别。"Delicate" 更多的是指某物需要特别小心和谨慎地处理,以避免损坏或破坏它的外观或形状。例如,可以说一件复杂精美的玻璃器皿是delicate,因为它需要小心地搬运和清洁,以避免刮伤或破裂。"Fragile" 更多的是指某物非常脆弱,容易破碎或损坏。例如,可以说一颗易碎的玻璃球是fragile,因为只要稍有不慎就会碎裂。因此,"delicate" 更强调谨慎和小心,而"fragile" 更强调易碎和容易损坏。北有云溪2023-06-30 08:59:012
