With DGD method, the electron microscopy observation has provided new information on the process of chromatin migration. That is: Firstly, the nucleus moved toward cell wall and a picture characteristic of synizesis stage of meiosis appeared; Secdonly, the transmigration of chromatin occured through CC, and a more extensive region constituted of nuclear skeleton left behind chromatin, which was named as"clear spaces" under light microscopy; Thirdly, at the late stage of synizesis, most of chromatin had gone into adjacent cells through CC and fused into a whole, and the nuclear skeleton left in the former cell gradually mixed with cytoskeleton in cytoplasm.

DGD—包埋去包埋电镜观察表明：百合花粉母细胞中有类似核纤层的结构存在；在染色质穿壁运动过程中，首先是细胞核向细胞壁靠拢，并可留下瞬间的运行轨迹——细胞核后方出现只有细胞骨架而少有细胞器的区域；其后是染色质开始穿壁，在穿壁染色质后方细胞核内出现无染色质仅有密集的核骨架的区域，到了染色质穿壁后期，大部分核物质都已穿至相邻细胞，并彼此融合，而残余在原穿出细胞中的核骨架己逐渐与原细胞的胞质骨架融为一体。

There are two types of maturation according to our observation.One is nucleocapsids obtained its tegument in the nucleus and enveloped from the inner nuclear membrane.Another is nucleocapsids entered cytoplasm through nuclear membrane,then obtained their tegument in the cytoplasm,enveloped from the plasma membrane,finally released by necrosis,exocytosis or other ways.

病毒成熟有两种方式：一为细胞核内核衣壳在核内获得皮层，通过核内膜获得囊膜成为成熟病毒；二为核内核衣壳通过内外核膜进入胞浆，核内和胞浆内的核衣壳在细胞浆中获得皮层，然后在各种质膜上获得囊膜，最后成熟病毒通过细胞破裂或其他方式释放到细胞外。

This dissertation discusses four problems that have relations with these topics. These problems are, i seismic moment tensor representation for explosions in ellipsoidal cavities and their seismic radiation patterns in the farfield; ii seismic waves from point sources in transversely isotropic media; iii yield-estimation by mb or mb for Chinese underground nuclear explosions and, iv simultaneously inversion for source parameters of underground nuclear explosions and parameters of apparent Lg Q for paths from source to stations.

本文讨论与此课题有关的椭球腔中的爆炸的地震矩张量表示及地震波辐射图案，各向异性介质中的点源激发的弹性波，由Lg波震级或Lg尾波震级估算地下核爆炸当量，由Lg波位移谱反演地下核爆炸震源参数及相关路径的Lg波视衰减参数等四个方面的问题。

Ban nuclear weapon testing is a vital part of the Comprehensive Test Ban Treaty , at the same time on-site inspection is the most important thing in nuclear inspection process.

禁核试核查是《全面禁止核试验条约》的重点内容，现场视察又是核查机制中最重要的组成部分。

Because nuclear power generation efficiency of thermal heat low, the thermal nuclear power generation thermal pollution than serious.

由於核能发电的热效率较火力发电低，故核能发电的热污染较火力发电严重。

Luminosity of the Sun , using its own gravity to put hydrogen Rafah , by the nuclear fusion of hydrogen into helium nuclear thermonuclear reaction enormous energy to the radiation from the surface of the internal transfer , launch into space .
