5.Based on the Light Utility Efficiency and CASA model, we set up a model to estimate the terrestrial net primary production (NPP) of China, which the 1KM MODIS data were used as main remote sensing data input in it. We estimated the terrestrial net primary production of China in 2001. And the temporal & spatial change of NPP was analyzed.

6.Because of the relative movement between the LEO satellites and the terrestrial user terminals, the very high handover rate during a call’s lifetime, including inter-spotbeam handover, inter-satellite handover and handover between satellite communication systems and terrestrial ones, will occur.
本文对低地球轨道(Low Earth Orbit,LEO)卫星通信系统中的切换与信道分配策略作了较为深入的研究,将切换与信道分配、资源预留等因素综合考虑,采用合适的切换算法来降低呼叫阻塞率和切换失败率,提高资源利用率,从而改善系统性能。 本文主要分为3个专题在第二、三、四章详细阐述。
7.The prediction of disastrous space weather is a hot topi c among solar-terrestrial physics and high technological fields.We propose that the future forecasting of the physical conditions that the violent solar disturb ance causes at the earth by propagating in solar wind depends heavily on the num erical method.This paper analyses the existing problems we are facing in the num erical prediction of disastrous disturbance events in solar-terrestrial space,an d then gives some suggestions for future study.For such a purpose,a six step sol ution method is developed to deal with one-dimensional symmetric interplanetary shock dynamics.It should be point out that that initialization of fully self-con sistent 3-D MHD codes considering the solar-interplanetary-geomagnetic coupled r elations with initial-boundary values at 1R⊙ of the global output of solar pl asma and magnetic field using available solar observations is an essential requi rement in space weather operational codes for forecasting purposes.
空间灾害性天气的预报是日地物理学界及高科技领域的热门话题.未来预测太阳剧烈扰动所造成的行星际风暴到达地球空间的状态势必借助于数值方法.浅析了空间灾害性扰动事件数值预报存在的问题及未来设想，针对这一目的对一维球对称问题提出了处理行星际激波的6步求解方法，指出未来空间灾害性扰动事件预报模式应是一个基于三维的以真实太阳风为背景自洽建立起来的、以太阳等离子体输出及磁场全球结构为初边值、太阳、行星际、地磁因果耦合模式.
8.This paper systematically summarized the characteristics of terrestrial stress precursory field of the Wuwei earthquake (Ms=5.3)on January 6, 1984 received by the terrestrial stress observational network in eastern Gansu Province.
本文由点到面系统地总结了1984年元月6日武威地震(Ms=5.3级)前,甘肃东部地应力观测台网所接收到的地应力前兆场特征。
9.The IAU 21st General Assembly held in 1991 resolved that the Terrestrial Time(TT)replaces the Terrestrial Dynamical Time(TDT) and the new terminologies of GeocentricCoordinate Time (TCG) and Barycentric Coordinate Time (TCB) were introduced at thesame general assembly. The reasons for introducing these time-like arguments, the relationships between these differnt time scales and the questions appearing in practical applications are described in this paper.
国际天文学联合会（IAU）自70年代末引进地球力学时TDT和质心力学时TDB后，又在第21届大会上决定以地球时TT取代TDT，并引进地心坐标时TCG和质心坐标时TCB两个新的类时变量，现对引进这些变量的原因、其间相互关系以及目前存在的问题作一介绍。
