辐射的

The latest analysis of the universe's uniform backdrop of gamma radiation now carves a 10 GeV hole in the low end of that range, Kevork Abazajian, a particle cosmologist at the University of Maryland, College Park, reported here this Sunday at the oddly timed April Meeting of the American Physical Society.

Kevork Abazajian在本星期日的美国物理学会上说，有关宇宙伽马辐射背景的最新分析表明，在辐射背景的最低处出现了一个100亿电子伏的空洞。

Change in the direction of propagation of radiation determined by change in the velocity of propagation in passing through an optically nonhomogeneous medium, or in passing from one medium to another.

当辐射通过光学异性的界面，或从一种媒质进入另一种媒质时，传播速度的改变而导致的辐射传播方向的改变。

Depending on the type of dosimeter used, due account should be taken of possible causes of inaccuracy including the change in moisture content, change in temperature, time elapsed between irradiation and measurement, and the dose rate.

根据所使用的辐射量测定器的类型，要考虑导致不精确的可能原因，包括湿度，温度变化，辐射和测量之间的时间差，及辐射剂量。

The relationships of pulse distortion depending on frequency, pulse width, rain rate and path length are studied .The conditions of the broadening and compression for pulse wave are given. Based on the scattering characteristics of fog, the attenuations and reflectivities at millimeter wave are computed and analyzed for radiation and advection fog. The attenuation along earth-space deduced by radiation and advection fog is obtained and the results are compared.
