“While experimental physicists and engineers tackled that problem, theoretical physicists had already been hard at work thinking about the next step: the ignition of a large mass of thermonuclear fuel by a relatively small fission explosion. The breakthrough came in early March 1951 (two months before the planned tests at Eniwetok), when Edward Teller and Stanislaw Ulam came up with a promising design (the details of which are still highly classified). Calculations based on the new design commenced immediately, most of them done by Los Alamos scientists. In addition, scientists used some of the earliest computing machines to help with calculations.”

人们做氢弹是要用最少量的裂变材料引发最大量的聚变材料。

黄先生提的用一吨重的U235外壳中间包上热核原料也应该工作，但是只可以用来自杀，没法去杀敌人。

泰勒最先的概念是SUPER，就是说用个小原子弹放中间，外边包上热核材料，乌乐姆告诉他你这样不灵，都炸飞了，没法聚变。

老道的狗屎构型也一样，用太多的U235，还放两边，脱了裤子放屁的东西，不值一提。

TU的构型解决了这些，原子弹不大，能裂变就行，先用X光射线把热核材料压一级，同时提供聚变需要的温度，冲击波再压一级，其实泰勒在中心还加了引发材料(因为初级裂变提供了大量中子冲击），更提供更大的压力。

因为光速很快，这样，

Although  essentially  weightless,  X-rays  can  exert  great  pressure.  In  an  H-

bomb,  the preressure  (several  million  pounds  per  square

inch)  is  exerted  uniformly  on  the  fusion material  and  long  enough  for  the  fusion  pro

cess  to  work  before  the  material  is  blown a part.
