In this paper, effects of atmospheric factors to Ka-Band earth-space links are analyzed, and the total fade distribution function is derived. With the scintillation prediction model, monthly averaged standard deviations and monthly percentage time averaged fade of scintillations for some of referential earth stations of our country are computed.

摘要本文分析了各气象因素对Ka-波段地空链路衰减特性的影响，得出了链路综合衰减分布函数，利用闪烁预测模型计算了全国各参考站点的闪烁月平均标准偏差和月百分比时间平均衰减值。

On Earth-space paths, this beam scintillation index model is significant for the laser imaging, tracking, controlling and guiding, and laser satellite-Earth communication.

高斯波束的斜径闪烁指数模型的建立发展了湍流闪烁理论，将对地－空路径光通信、成像、遥感、激光制导和强激光系统的设计和应用具有重要的实际意义。

Therefore, in order to ensure the transmission quality, reliability and economical efficiency, we must master the rainfall attenuation influence of earth station setting areas accurately while the designing the earth-space satellite communication links.

因此，在设计地—空卫星通信线路时，为了保证通信系统传输质量、提高可靠性及经济性，就必须要准确地掌握地面站设置区域的降雨衰减所产生的影响。

He then explains that the "full Earth" would bathe the Moon with "earthshine" even though the Sun is nowhere in sight, just as the full moon bathes the Earth with soft moonlight when the Sun has long set.

接著，他说明纵使已看不到阳光，「〔阳光〕满〔照的〕地〔球〕」将使月球沈浸在「地〔球反照的〕光」之中，就像日落后，满月会使地球笼罩在柔和的月光中一样。

Using a one-dimension magnetic filament in the Earth\'s magnetotail to represent the bubbles,we examine the motion of bubbles created by reconnection in the Earth plasma sheet.Some properties of time evolution of the filament can be obtained from the numerical simulation.The magnetic field line in the filament created by reconnection is more dipolar than the surrounding magnetic field line,and the motion of the filament displays a strong earthward flow.The results show that MHD waves such as an Alfv?

本文研究地球等离子体片中重联后的磁泡的运动，用地球磁尾中的一维磁细丝来表示磁泡，通过数值模拟发现，重联产生的磁细丝磁场比周围磁场偶极性更强，运动时表现出了很强的地向流。
