The aim of the paper is to design and fabricate five mulitilayer mirrors in shorter wavelength of soft x ray region and makes up of soft x ray spectrometer which is applied to ICF experiment.

在ICF实验中，激光等离子体产生的x光主要分布在亚仟电子伏特区（0.1-1.5keV），它的总能量、能谱特征、发射时间过程和空间分布都是理论和实验极为关心的基本数据。

The results of the simulation analysis and experiments indicate that the loss of ultraviolet scattering transmission in atmosphere is high because of the particle scattering and absorbing in solar-blind zone; that is, the received power can descend 20 dB with the distance increasing 10 times. Therefore, the ultraviolet scattering is fit for short range communication. In short range, the pulse extension due to scattering is at microsecond order and its influence for low and moderate bit rate communication systems is weak. Since the light output power of a single ultraviolet LED is low, a multi-LED array can be used to increase the transmit power and extend the communication range.

仿真分析与实验结果显示：日盲区紫外光在大气中散射传输时由于大气粒子的强烈散射与吸收，传输损耗较大，距离每增加10倍，接收功率下降20dB，因此日盲区紫外光大气散射通信适用于近距离通信场合；近距离传输时散射造成的光脉冲多径展宽为微秒量级，对中低速通信系统影响较小；单个紫外LED发光功率较低，可通过多个LED阵列来提高发射功率，增大通信距离。

If we are to ultra-light travel, the moment arrived in the solar system 100 light-years from the planet, we can launch on Earth from the light is the light of a century ago.

如果我们以超光速旅行，瞬间就到达距离太阳系一百光年的星球，我们看地球上发射过来的光线就是一百年前的光了。

Celebs are still the major force on the list, However, some undersung grass-root bloggers do have what it takes to make them like a real star, so some star-makers are scouring around, find some and give those fresh faces' star career a kicks-tart, or make them at the frontpage of tabloids, or help them steal the spotlights from others super nova in the celebrity universe.

The results showed that CTR degradation and noise increase were due to the increase of Si-SiO2 interface defects at the collector junction and emit junction in phototransistor.

结果表明CTR退化和噪声增加都归因于辐射后光敏晶体管集电结和发射结处Si-SiO2界面缺陷增多。

Optical mouse lens system of the launch and the combination of components is one, fixed in the shell on the mouse, and the phototransistor is fixed in the circuit board, the location of the two must be very precise, manufacturers in the calibration of the location with hot melt adhesive to a fixed LED components in the lens, and if in use, the mouse has been touched or fall too much vibration, it is possible to make hot melt off, shift light-emitting diodes.

光电鼠标的发射及透镜系统组件是组合在一体的，固定在鼠标的外壳上，而光敏三极管是固定在电路板上的，二者的位置必须相当精确，厂家是在校准了位置后，用热熔胶把发光管固定在透镜组件上的，如果在使用过程中，鼠标被摔碰过或震动过大，就有可能使热熔胶脱落、发光二极管移位。

It is because of Cerenkov effect "electromagnetic radiation emitted when a charged particle passes through an insulator at a speed greater than the speed of light in that medium"

正是因为切伦柯夫效应&当带电粒子穿过透明介质时，如果它的速度超过了光在介质中的速度时，会沿一定方向发射可见光。&
