热辐射密度以核爆点距离平方倒数的速度衰减,爆炸、冲击波、致电离辐射效应的衰减速度则更快。
The intensity of thermal radiation decreases only as the inverse square of the distance from a nuclear detonation, while blast, shock, and prompt ionizing radiation effects decrease more rapidly.
水平方向上大气紫外透射比的指数衰减规律决定了系统工作的局域性和保密性。
Exponential attenuation of UV atmospheric transmittance for the horizontal paths decides that the UV communication system works locally and safely.
所以这个平方,在原点处非常高,随着离核子的距离,越来越远,它逐渐衰减,并且它和角度是没有关系的。
So this squared at the origin is going to be a very high probability, and it decays off as you get farther and farther away from the nucleus or from the center, and that's independent of the Angle.
