反射

The reflecting telescope, pioneered by Isaac Newton in the 17th century, later became the instrument of choice because of its use of mirrors, which could be constructed successfully at much great sizes than the glass lenses used in refracting telescopes.

反射望远镜是艾萨克·牛顿于17世纪首先倡导的，后来由于望远镜上反射镜的应用面成为了一种首选的设备，比起折射望远镜里使用的玻璃透镜来，它能够成功建造出尺寸大得多的望远镜。

Finally, We analyze and experimentally demonstrate that both the bandwidth of the fiber Bragg grating's short wavelength loss and the bandwidth of fiber Bragg grating's reflection increase with the increase of strain gradient along the length of grating.

最后，我们对光纤光栅的反射和短波损耗的应变特性作了理论分析和实验测试，发现在光纤光栅的反射带宽随光栅轴向应变梯度的增加而增加的同时，光栅短波损耗带宽也随光栅轴向应变梯度的增加而增加。

So chirped fiber gratings have broad reflection bandwidth. The group delay in chirped fiber grating reflection bandwidth changes gradually. These properties are what other type fiber gratings do not have.

所以chirped光纤光栅具有宽的反射带宽，在反射带宽内具有渐变的群时延等其它类型的光纤光栅所不具备的特点。

Based on the influence of reflection phase of fibre Bragg grating on the transmission spectrum of fibre Bragg grating Fabry-Perot cavity, the reason for the error of traditional coupled mode theory when calculating the reflection phase of uniform FBG is analyzed.

基于光纤Bragg光栅反射复振幅相移对FBG法布里-珀罗腔透射谱的影响，分析了传统耦合模理论计算均匀FBG反射复振幅相移产生误差的原因。

Diffuse – We must also observe where on the spectrum for Diffuse to Reflective our glass needs to be.

镜面反射-我们必须遵循对于玻璃来说的漫反射光谱。

Because the most noise of people are often part of the treble, while the treble is a straight line, and enable it to most of the reflective glass, insulating glass, you can consume it without some reflection to do perish.

因为最噪人的往往是高音部分，而高音是直线传播的，用玻璃可以使其大部分反射，中空玻璃则可以使其没有反射的部分消耗殒尽。

We analyse the mechanism of reflectivity reduction caused by charged particles radiation.

并分析了辐照引起的反射镜反射率下降的原因。

The preliminary experiment in air shows that the radiation reflectivity is not more than 20% at the wavelength range of 500~2400 nm.

对空气中微构造硅的辐射反射的初步研究表明，在500~2400nm范围内的光辐射反射率不高于20%。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
