只要墙壁和屋顶足够厚实，能够吸收尘降物颗粒发散出来的辐射，它们可以是任何可以给你提供保护的空间。
They can be any protected space, provided that the walls and roof are thick and dense enough to absorb the radiation given off by fallout particles.
其他特征还有，疼痛呈辐射状向大腿窝或腿部发散，或者越过骶髂关节向腹腔内部发散。
Other signs include pain radiating into the hip socket, or down the outside of the leg, or deep inside the belly over the anterior surface of the S-I joint.
激光这个词是由辐射的刺激发散产生的光的扩大的英文首字母缩略词而创造的。
The word laser was coined as an acronym for Light Amplification by the Stimulated Emission of Radiation.
高辐射功率的光束会有高的发散度。
光学渡越辐射（OTR）测量结果显示：OTR是由于超热电子输运穿越固体靶所致，而辐射区域呈圆盘状、有发散角、有光强分布；
Due Optical Transition Radiation(OTR) is produced by the hot electrons transport through solid targets, region of OTR is have lager radiation angle and optical intensity distribution.
