Molecular Weight Distribution

Calculation for Polymer

1. Number Average Molecular Weight \[\overline{M}_n=\dfrac{\sum{n(D_n+P_n)}}{\sum{D_n+P_n}}w_m\] Where $D_n$ and $P_n$ are the number of moles of dead and growing polymer chains of degree of poly...

全球作秀

没有人再去关心真正发生了什么，也无人要去拯救。

福岛核泄漏让我感到了为了短浅的既得利益，所有人都可以把自己的未来埋葬来做一场秀。一个很清晰的事实就是直接接触核裂变的任何物质都会有长久的放射性，且对动物致命。而另一个很清晰的事实也是在这一场从未经历过的特殊核泄漏中，受辐照的水潜藏危害是未知的。最后一个很清晰的事实则是人类是有洁癖的，除非是宇航员那种万不得已要把自己的尿循环过滤成干净的水来喝，在地面上任何一种可能吃自己排泄物的行为都是可能...
