Dynamic Characteristics of Inter-Satellite Links in LEO Networks

To establish an efficient inter-satellite link (ISL) in an LEO network, the effect of geometric characteristics of ISL on the ISLs and the devices on the LEO satellite should be examined. Because of the continuous movement of the LEO satellite, the time-varying behaviours of the ISL's geometric charactersistics continuously change with the changes of the satellite's position on the orbit. These dynamic geometric characteristics of the ISLs are important for ISL's performance analyzing and the design of the devices on the LEO satellite. This paper describes dynamic geometric characteristics of ISL, analyzes the impact of these regulations on the tracking system of the satellite's antenna and the power adjusting system of the satellite's transmitter, with the Iridium system as an example.

Radar Imaging Based on Iterative Algorithms

It has long been realized that the problem of radar imaging is a special case of image reconstruction in which the data are incomplete and noisy. In other fields, iterative reconstruction algorithms have been used successfully to improve the image quality. This paper studies the application of iterative algorithms in radar imaging. A discrete model is first derived, and the iterative algorithms are then adapted to radar imaging. Although such algorithms are usually time consuming, this paper shows that, if the algorithms are appropriately simplified, it is possible to realize them even in real time. The efficiency of iterative algorithms is shown through computer simulations.

D－胺基半乳糖（D－galactosamine）对小白鼠肝脏的损害作用

给小鼠一次性腹注Ｄ－胺基半乳糖（Ｄ－Ｇａｌｎ）６００和１２００ｍｇ／ｋｇ，或１６小时内连续６次腹注３００ｍｇ／ｋｇ，停药后４８小时，血清谷丙转氨酶（ＳＧＰＴ）明显升高，局部肝细胞呈现肝炎病理形态改变。病变机理是过量Ｄ－Ｇａｌｎ入肝代替了尿苷二磷酸葡萄糖的代谢途径所引起的。
