散射透镜

First,the planar waveguide models for Rotman lens and its feed lines which incorporate the dispersion effect with frequencies are set up.Then the aperture electric fields at lens ports are expanded by appropriate waveguide mode functions and substituted into the contour integral equation.The multimode scattering matrix of the lens can be acquired by solving the contour integral equation by using Galerkin method.

首先建立了考虑色散效应的透镜的等效平板波导模型，然后选择适当的波导模式函数展开透镜端口上的场，并利用Galerkin法求解其边缘上电场满足的轮廓积分方程即可得到透镜的多模式散射参数。

To make picture clear, the electron beam that must come out to be being hit from electron gun undertakes focusing is handled, let electron beam pass electron lens, be opposite with optical lens of beam of light collect action likeness, the electron beam assemble that opens scattering rises, get on fluorescent screen one shines again small spot, add the effect of scanning circuit, ability shows clear picture.

为了使图像清楚，必须对从电子枪打出来的电子束进行聚焦处理，让电子束通过电子透镜，和光学透镜对光束的聚集功能相似，把散射开的电子束会聚起来，在荧光屏上得到一个又亮又小的光点，加上扫描电路的功能，才能显示清楚的图像。

When computing the diagonal elements of the Galerkin matrix, one will encounter the integral of Hankel function, the Green's function of 2-dimensional Helmholtz equation and the cosine weighting function, whose integrand is singular in the integration range. A new approach is proposed to deal with this kind of singular integrals, which is pivotal but have not been reported so far.

首先建立了透镜边缘上任一点的电场满足的边界积分方程，然后选择适当的正交模式函数展开端口上的电场分布，采用边界元法的思路及Galerkin法将该积分方程离散化为—矩阵方程求解即可得到透镜的多模式散射参数。

Next, we reviewed the connection between RBLs and XBLs and the energy radiative process of BL Lacertae. Synchrotron radiation from radio to optical band and inverse Compton Scattering in γ ray wavebands are a wide accepted point. The beam model and gravitationally lensed model are two models associated with the radiative process. At present people tends to favor the previous one.

接着我们对射电选BL Lac型天体和X射线选BL Lac型天体之间的关系以及BL Lac型天体的能量辐射机制进行了评述，从射电到光学的同步辐射和γ射线波段逆康普顿散射的观点受到大家的普遍接受，射束模型和引力透镜模型是与辐射机制相关的两种模型，目前比较倾向于射束模型的解释。

Based on the scalar scattering theory,a mathematical model of the light scattering intensity distribution of laser beam on the back focal plane of Fourier lens by a rough surface is established by means of the probabilistic-statistical method.

本文以标量散射理论为基础，用概率统计方法建立了粗糙表面的光散射强度在傅氏透镜后焦面上的分布的理论模型，采用镜反射方向的光强与某一散射方向的光强之比来计算R_q值的方法，导出了理论计算公式。

At time of final inspection, all fixtures and equipment shall be clean, fully lamped, and be complete with required lenses or diffusers, reflectors, side panels, louvers, or other components necessary for the function of the fixtures.

在进行最后的检查时，所有的灯具都应该是干净的，全部安装的光源，并且配备了所有需要的透镜、散射器、反射器、面板、百叶和其他必须的功能组件。

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。
