The irradiance on the earth synchronous orbit and median orbit in the standard atmosphere was computed.

对地球同步静止轨道、中轨道卫星标准大气下的核爆光辐射探测器的接收照度进行了计算，得出了理想状态下探测器的动态范围及灵敏度。

Based on the analysis of the architecture and characteristics of the GEO/MEO TDRSS for China, two system schemes are given.

在分析了我国可采用的静止轨道和中轨道跟踪与数据中继卫星系统的系统结构和特点的基础上，给出了2 个系统方案。

中文摘要：在分析了我国可采用的静止轨道和中轨道跟踪与数据中继卫星系统的系统结构和特点的基础上，给出了2 个系统方案。

The analysis and simulation results indicate that the MEO- TDRSS can provide better coverage performance with more implementing cost.

仿真结果表明，中轨道跟踪与数据中继卫星系统能够提供更好的覆盖性能，但实现难度大于静止轨道跟踪与数据中继卫星系统。

On the basis of the statistical characterestics of satellite meteorological infrared cloud charts this paper presents a coding algorithm of "Sub sampling+Modified JPEG+Image enlarging",realizing a compression ratio of 50∶1～100∶1, with the PSNR of 35～40dB and visually unperceptible distortion.

依据GMS卫星红外气象云图的统计特性，提出了一种&亚抽样＋修改的JPEG＋图象放大&的静止图象编码方法，使有失真压缩比在50∶1至100∶1时，恢复图象峰值信噪比在35dB～40dB之间，主观质量无视觉可觉察到的失真。

The idea was two decades ahead of its time, and helped to attach his name to the geostationary orbit above the equator. In 1962, at the chilliest part of the cold war and just after the launch of Sputnik had heralded the space age, he discussed in "Profiles of the Future" the implications of transatlantic satellite radio and television broadcasts, with information raining down on previously isolated parts of the world.

这一设想足足超前了20年，环赤道同步静止轨道也因此以他的名字命名。1962年，冷战正酣，苏联的人造卫星发射揭开了空间时代的序幕，克拉克写下了《未来掠影》一文，描述了他用越洋卫星广播甚至电视节目将全世界的各个角落连结成一体的设想。

这个想法领先于那个时代20年，环赤道同步静止轨道也因此以他的名字命名。1962年，冷战时期，苏联的人造卫星发射揭开了空间时代的序幕，他在上畅谈跨越大西洋卫星电视广播的想法，将信息撒播向早前那些各自孤立的世界。

By using a one-dimensional variational (1D-Var) method, relative humidity derived from GMS-5 multi-channel satellite images and from NOAA-14′s TIROS Operational Vertical Sounder radiances were corrected by 6-h RH forecasts of the MM5 meso-scale NWP model.

这两种反演资料分别是用统计反演法反演GMS-5静止气象卫星多通道遥感信息得到的GMS反演地球大气湿度，和用同步物理反演法反演NOAA-14极轨卫星的TOVS晴空测值所得的TOVS反演湿度。

The application of electric propulsion system in China s geostationary satellite in the future is a necessary trend.

将氙离子电推进系统应用于静止轨道卫星平台，除了要解决电推力器本身的问题之外，还要在系统应用方面做大量工作。

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。
