It's as if this celestial laser beam were designed so as to actually shift the atomic structure of the pure corporeal frame of the virgin's body until that body is so rarefied, so pure and ethereal, that it's nothing but soul.

这束天国的激光好像被设计成,去把处女纯净肉体的原子结构,变的纯化，纯粹和飘渺，那就是灵魂。

Also, what's the energy per photon of this red laser pointer, and then it's also worth trying a calculation dealing with intensity. So let's also try calculating the numbers of photons that would be emitted by this laser pointer, if, for example, we were to use it for 60 seconds and this were a one milliwatt laser.

同样，红色激光笔的,每个光子能量是多少，这也值得用处理强度的方法计算一下,让我们也计算一下,有多少光子会从这个激光笔射出，举个例子，如果我们使用它持续60秒,这里会有一毫瓦的激光。
