你可以得到一个弹性散射的碰撞，在那，原子就会反射，铀235原子，还会继续，那也可能会减慢一点。

You can have an elastic scattering collision where the neutron just essentially bounces off the uranium 235 atom and just continues on and it's possibly slowed down ever so slightly.

例如，首先可能要测试物体碰撞盒子，看是否需要基于测试的多边形，或者碰撞盒子交叉点可能经常成为提供满意结果的唯一来源。

For example, object bounding boxes may first be tested to see if polygon based testing is necessary - or bounding box intersection may often be all that is needed to provide acceptable results.
