最后介绍使用随机射线建模超宽带室内信道的多径传播轨，在此基础上可以得到信道特性建模的基本随机变量，以及无线电波传播的概率模型等应用。

It can also occur if the radiation is in the wavelength range of ultraviolet radiation, X rays, or gamma rays.

The paper presents a new filling-sample method by which the sample quantity filled in a box depends on the energies of γ-rays to be measured. The detection efficiencies of HPGe detector were calculated by using Monte-Carlo method for various γ-ray energies and at various soil sample quantities in a box, and the optimal filling-sample quantities for different-energy γ-rays from radioactive nuclides of 238U, 232Th, 226Ra, 40K, are respectively obtained.

本文提出了样品装量与待测γ射线能量有关联的装样方法，并用蒙特卡罗方法模拟计算了不同能量γ射线的探测效率与样品装量之间的关系，得到用HPGe γ谱仪分析238U、232Th、226Ra和40K等放射性核素活度各自的最佳装样量。

Among all sorts of radiotherapy equipments, linear accelerator fundamentally takes use of electronics rays and X-rays to treat an illness.

在常用的治疗设备中，直线加速器主要是利用电子线和X射线照射靶区来达到治病的目的。

The first profile encloses a Master card that generates between two and six infrared rays and transmits them to a Slave card, placed inside the second profile that has the task of retransmitting the rays received to the Master card, acting as a kind of "electronic mirror".

一侧嵌入发射器，在两侧之间产生六道红外线，投射向安装在另一侧的接收器，再经其返回发射器，类似一种&电子反射镜&。

The Cherenkov telescopes do not actually detect the gamma rays directly but instead detect the flashes of visible light produced when gamma rays are absorbed by the Earth's atmosphere.

只有10 ％的伽玛射线源的非瞬态来源。这些稳定的伽玛射线发射器包括脉冲星，中子星和黑洞的候选人，如活动星系核。

As professor of physics at the University of Wurzburg, he was experimenting with a Crookes' radiometer when he noticed that when cathode rays struck the end of the tube, rays of a new kind were emitted that were capable of penetrating matter.

作为Wurzburg大学的物理教授，Roentgen当时正在使用Crookes的放射计进行试验。他注意到当阴极射线撞击到射线管的末端时，会发出一种能够穿透物体的新型射线。

Others began considering the virtues of a concave paraboloidal mirror as primary receptor: it had been known since Antiquity that such a mirror would bring parallel incident rays to a focus at one point.

其他人开始考虑的美德，凹抛物面反射镜作为主要受体：它已被称为自古以来这样的一面镜子，会带来平行事件射线的焦点在1点。

In summer, because the vertical incident solar rays regionmoves by the equator to the north, causes of southeast trade crossingthe line the southern hemisphere to change the southwest monsoon toinvade Northern Hemisphere, meets one another with the originalNorthern Hemisphere's Northeast Tradewind, compels crowds this airrise, the increase convection current, again because the southwestmonsoon and the Northeast Tradewind direction is different, meets oneanother often creates the undulation and the whirlpool.

在夏季，因为太阳直射区域由赤道向北移，致使南半球之东南信风越过赤道转向成西南季风侵入北半球，和原来北半球的东北信风相遇，更迫挤此空气上升，增加对流作用，再因西南季风和东北信风方向不同，相遇时常造成波动和旋涡。

It was just a normal day of school

那只是上学的普通一天

Which is a very good reference in this issue.

这是一个在这个问题上很好的参考。
