复合的

By itself consists of the second part of this thesis, which provides adetailed discussion of the so-called finite-time disentanglement in bipartite sys-tems first introduced by Yu and Eberly. The results show that this phenomenonis due to the energy transfer between the system and its surroundings or dueto the internal energy transfer.

在北京香山樱桃沟野生的十字花科豆瓣菜上发现有芜菁花叶病毒、黄瓜花叶病毒以及一种未报导过的"小白斑"病毒的复合病。小白斑病毒在20多种寄主上，包括十字花科，单独汁液接种时只能产生局部坏死病斑，不能系统侵染；单独接种而能系统感染的寄主有百日菊，只产生极轻微的深浅绿花叶，甚至有时几乎无病状。小白斑病毒能在复合病情况下系统存在于豆瓣菜中是值得注意的一种现象。

Detailed description has been given individually to the abnormal colours, lineament and circular structure and image features on the multi-geographycal information composite image. We have studied the ore control effect of circular and lineament structure to the multimetal ore, and come to the point that the Xianghualing region is a complex ore control area by circular and lineament structure.Therefore, we build a remote sensing imag model for ore field in the region. Within the circular structure, the northwest lineament crosses the northweast lineament and forms frames that control the metal ore distribution. According to the features of the found deposits and their coherent image, we conclude that there are two symbols for ore looking.
