论文从电磁散射机理入手，明确提出了真实目标的复杂散射行为与理想的点散射中心模型描述这两者间的失配问题。

According to scattering phenomenology, we point out that the commonly used point scattering models fails to accurately describe the complex scattering behavior of real target.

红外照相机聚焦的是一根手指(或者相似大小的物体)破坏水平面、散射光线的点。

An infrared camera watches for spots where a finger (or similarly sized object) breaks the plane and scatters the light.

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.
