A simple linear model for the fixed diffraction angle was set up by numerical calculation and parameter fitting.

针对卫星光通信中衍射角固定的应用情况，通过数值求解和参量拟合，建立了一个基于平面方程的简单控制模型。

Luneberg lens is a spherical lens which its permittivity varies with normalized radial coordinates. It is fabricated by using different homogeneous dielectric centrically layered media. The lens can focus a parallel beam of rays from any direction exactly at a point on the surface. If it is made by adding a reflecting surface "metallic cap", it is called Luneberg lens reflector. It can reflect incident wave into plane wave in incoming direction. It is usually applied in antenna, radar reflector,satellite-based, and mobile-communucation.

龙伯球透镜为一种介电系数与半径成一固定比例的球形透镜，大部分是由数层不同介电系数介电质组合而成，而其主要特性能够把入射波聚焦到球表面一点，假使在透镜表面处镀上一圆锥角金属层即为龙伯球透镜反射器，能把入射波依平面波的型态反射回原入射端，通常用於天线、雷达、卫星通讯、军事等方面。

However, the museum C. heterodon specimens were preserved in formalin. It is necessary to approach the methods of effectively extracting the genomic DNA from formalin-fixed C. heterodon, and the feasibility of using the extracted DNA in microsatellite-and mitochondrial analyses. In the present paper, the genomic DNA of ten formalin-fixed C.

然而，过去的铜鱼标本都保存在福尔马林溶液中，有必要探讨从福尔马林固定的铜鱼标本中有效提取基因组DNA的方法以及这些DNA用于微卫星和线粒体分析的可行性。

If that orbit is also in the plane of the equator, the satellite will hang in the sky over a fixed location in a geostationary orbit.

如果那轨道也是在地球赤道的飞机中，卫星将威胁一在一同步轨道中的固定的位置在天空中。

The satellite placed in a geosynchronous orbit revolves once a day with the earth, so it appears to be fixed over one place at all the time.

地球同步轨道上的卫星，每天随地球转一圈，所以看上去似乎总固定在一处。

A GSO satellite appears stationary above the earth, because of its running direction and orbital velocity is as same as the earth's rotational direction and speed respectively.

由于静止的运转方向和角速度与地球的自转方向和角速度相同，卫星的空间位置与地面任意地点的相对空间关系固定不变。

It is widely applied in many fields,such as fixed and wireless communication,satellite communication,digital television and broadcasting,optical fiber communication,and magnetic recorders,etc.

Earth stations, gateway stations or tracking telemetry and command stations of the feeder links of space radio communication services other than fixed satellite services

卫星固定业务以外的其他空间无线电通信业务馈线链路地球站、关口站或者测控站。

There often exist some components or subsystems fixed at the satellite main structure in stowed configuration during launch process due to the space limitation.These components or subsystems will be deployed by using deployment mechanismwhen the satellite reached the specified orbital with designed satellite attitude.

人造卫星内许多元件於发射期间，需要以摺叠方式固定在人造卫星主结构上，而当人造卫星运转至特定的轨道点及特定的卫星姿态后，才逐一地利用展开机构将上述的结构展开至特定位置。

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。
