Test Observation of the Solar Radio Fast Synchronous Observation System at Four Wavelengths and Its Significance

四波段太阳射电快速同步观测系统的试观测及其意义

Synchronous or quasi synchronous three dimensional sea ice air comprehensive observation was conducted during China's First Arctic Expedition in summer of 1999. Based on the data from that expedition the role sea ice plays in sea air exchange was studied.

本文用了1999年夏季中国首次北极科学考察队对海冰、大气和海洋进行的同步和准同步的综合立体观测所获取的资料，研究海冰在海气相互作用中扮演的角色。

Repeat sun-synchronous orbit is one of the most important orbits for earth observation missions, because the orbit can satisfy the requirements of illumination and temporal resolution.

太阳同步回归轨道既可以满足光照条件的要求，又可以满足时间分辨力的要求，是对地观测航天器首选轨道之一。
