Ⅰ Cu-3(btc)是什么物质

BTC是（三氯甲基）碳酸酯的简称，是一个化学物质的简称，主要有碳、氯、氧组成，化学式是C3Cl6O3，可作为剧毒光气和双光气在合成中的替代产物。

BTC=Bis(trichloromethyl)carbonate 双（三氯甲基）碳酸酯，即三光气。

CAS Registry Number32315-10-9

分子式 C3Cl6O3

分子量 296.748

(1)cu2btc3扩展阅读：

三光气在有机合成中用作试剂，并且是用于各种化学转化的光气的较不危险的替代物，包括将一个羰基键合至两个醇，并将胺基转化为异氰酸酯。

三光气的毒性与光气相同，因为它在加热和与亲核试剂反应时分解成光气。 即使微量水分也会导致光气的形成。 因此，如果对光气采取所有预防措施，则该试剂可以安全地处理。

作为剧毒光气和双光气在合成中的替代产物，本品毒性低，使用安全方便，而且反应条件温和，选择性好，收率高。

本品为二级有机有毒品。宜存于干燥、阴凉、通风的库房内，远离火源，并与有机胺、碱性化学品等分开保存。

Ⅳ 求仙剑5的激活码，一个码可以用两次的，各位哥哥姐姐给个呗！谢谢啦~~~

这个你只能买正版的了……

Ⅳ I9100 imei是359959041165071谁能帮忙查一下，谢谢！

三星水货大部分手机是没有专业查询网站，可以试试下面查询指令吧。
*#*#197328640#*#*#*

其实 *#197328640# 就出 出现 Service Mode (服务模式 界面)

【1】 Debug Screen 调试模式 主要用于调试，并提供各种调试数据、手机参数的监看
【2】 Version Info 版本信息
【3】 UMTS RF NV UMTS射频校准
【4】 GSM RF NV GSM射频校准
【5】 AUDIO 里面有 Voice Call Video Call Multi-Audio Table ....等
【6】 COMMON 里面有FTM Debug Info RF Scanning ....等

选择 2 2 4 就可以查生产日期
进拨号盘：
输入*#06# 记下IMEI号
继续进拨号盘：
输入*#272*IMEI# IMEI就是你刚才记下的15位IMEI号码。
可以看到Sales Code后面的白框里会有3个字母。这个就是销售国的代码。记下到下表中查对应的国家即可。
比如说我的9000 ，Sales Code是XEU ，在下表中可以查到XEU = UNITED KINGDOM，即代表手机是销往英国的，欧版。TGY 就是港版
英文不行的话请自行谷歌或有道吧。

Ⅵ python中else的格式

截图出来看看啊 不然没有法看 没有缩进

Ⅶ 我想了解一些现在流行的英语缩写希望朋友们提供

呵呵，我这儿都是聊天用的缩写，不知道合不合你意，不过我想，都是为了学英语嘛，应该也用得上呵呵

下面这些是一个美国朋友帮我总结的，很多都不常用，但是却很全！有许多都是地道的美国口语，我们平常不这么说，可是正综的老外都这么说的呵呵。另外，向你推荐一个工具，叫skype，是一个聊天工具，和QQ一样地聊天工具，不过它的普及率远高于QQ，全世界每个国家都有skype友，我最近正和几个美国朋友聊得欢，一个是麻省理工学院的学生，还有一个是加州一个不出名的大学的教授，还有夏威夷的朋友。这两天，我认识了两个美国高中生，还有一个伊拉克人，我们四个总是一起语音聊，大家都很冷静，美国人和伊拉克人竟然也能忘记一些东西，只谈生活中的趣事。要是你对这个工具感兴趣，可以到TOM网站上下载！

ps:以上信息是以上海港作为参考，来自中国国际货运网．这里所罗列的航线，只是说比较成熟的航线，可供你参考．但是并非是绝对的，比如非洲线的话除了地中海航运外，还可以走法国达贸．澳线的话，中远的不错，船期准，速度快．美线的也可以APL.中东线的话象PIL，现代商船也是不错的．还有近洋线的话，那选择就更多了，如锦江，海华，烟台海运等等．船公司的选择主要还是看你客人有什么需要，是否指定船公司，还有就是价格，船期，挂靠港，目的港代理等因素了．
