I only know how to read a file line by line
or read in the whole file as a string.
But how to read/match multiple lines conditionally?
e.g. a file contains certain lables:
xxx
yyy
Begin: zzz
aaa
bbb
Ene: ccc
ddd
I need the script to read/match multiple lines between the Begin/End
pair as a single string. But for other lines, just read
them one by one.
Is there any easy way to do this?
Thanks.

来自主题: Biology版 - 小生物公司面试着装
非常感谢各位的建议!!! 的确非常有帮助, 这里具体汇报一下:如sunnyday和Ene
所建议,两次面试都着正装,并且是不同的西装和领带 (虽然气温90o,下车前打领带
,穿上西服,也不至于热),这样自我感觉会好些。和CEO谈的特别投机, 原定1个钟头
,最后一直聊了4个半小时,主要是结合job description 和第一次面试与CEO的谈话确
定的工作重点大谈精心准备的工作计划和创新设想,这似乎很合他公司发展的需求,后
来他很兴奋,大谈生意经,可能觉得我从Academic到Industry需要mentoring,谈了经
营公司的理念,企业文化和以市场为主导的技术创新,所以我就听着就行了,倒是也乐得
轻松,他似乎感到有个好听众,总体效果还是不错。最后他主动提出senior scientist
有点低,说给个Director的职位,具体package下周发给我,然后再谈。总之出乎意料
的顺利。 再次感谢各位!!!

Your opinion is pretty important. Thanks.
Currently, the most challenging problem with biomass is that it's producing, gathering, and treating efficiency is pretty low, and therefore the net energy produced is much smaller than the energy used today, which is dominated by fossil fuel. Besides, the global energy demand may increase greatly in the future. Biomass is good and important, but many reports said, and I would agree, that it's very challenging that biomass can meet the requirement of ene

来自主题: Chemistry版 - 请教lithium-halogen exchange反应
Start With distilled THF as Solvent, Do not use hexanes, lithium halogen
exchange should be done at -78 degree over 30 min. Then add dibromohexane
in THF dropwise at -78, and subsequent warming to rt.
Both Lithium halogen exchange and SN2 reaction (in this case) work better in
a polar solvent. There is no point of using hexanes. Do not use TMEDA which
might result in a deprotonation at the 5 position.
Side reactions: 1. elemination to form 5-bromopenta-1-ene. It is difficult
to avoid 2. dimer

来自主题: Chemistry版 - 镍-钴合金的硼化物添加剂
不好意思,受朋友委托想问一下问题,不知谁是这方面的专家,请推荐。
1,2-Diphenyl- 1,2-bis(dichloroboryl)ethylene;bis(trimethylamine)-1,2-
diphenyl-1,2-bis(dichloroboryl)ethyl ene.
问题 1:这两种物质是否可以镍-钴合金中起到细化晶粒的作用。
问题 2:通过加入这两种物质,是否可以形成镍和钴的金属间化合物。
问题 3:如果在镍-钴合金中加入硼元素,既起到细化晶粒又能形成金属间化合物,起
到双重强化的作用, 如何做?用什么物质?
问题 4:要在镍-钴合金镀层中达到含有20-25%的硼元素,镀层是非晶态,又要如何做?

It is not a big deal for properly engineered structure. What we deal every

2. Ejector Stack是什么?“烟囱”还是“推钢机推料”?这个术语与reformer和

3. 在“直接还原级铁球矿和铁块矿的优选特性”下,有一项是clustering (% plus 25
