Lishui movement is one of the important movements in the late peried of Yanshanian move ment, which refers to the diastrophism reflected by the angular discordance between Tiantai group and Younkang group.

本文以翔实的地质资料，就丽水以南吴弄口盆地的永康群与丽水南明山一带丽水盆地的天台群之间呈角度不整合接触关系，及其地层层序作了全面论述，认为它们之间存在一次重要意义的地壳运动──丽水运动。

On the basis of the previous work, we make further study on the mechanism of the denucleation process, especially on the role of different cytoskeletal elements in the denucleation process. To clone and sequence a gene related to terminal differentiation of erythroblast, and construction of two cDNA libraries of erythroblast differentiation. The results of our study are as follows

本文在我室前期工作的基础上，对红系细胞终末分化中的排核机理作了进一步的探讨，克隆、测序并表达了一个与红系细胞终末分化相关的基因，另外，还成功地构建了小鼠终末分化和差减cDNA两个红系分化cDNA文库，为本室以后的基因克隆工作打下了基础。

In this paper,the development and research progress in sequencing of rice genome are reviewed.

At last , this paper discusses reservoir characteristics in development period and suggests some theoretical ideas as well as techniques, major works is follow :(1) The combines of sequence stratigraphy , the flatten techniques of 3D seismic interpretation with 3D visualization , the paleotopography and river system in studied area are reconstructed and its controlling to developing of karst fracture and vug carbonate is analyzed , the affects of different paleo-domain unit on developing degree of reservoir storage space are presented .

在理论研究、技术方法方面作了一些建设性的工作，主要包括：(1)利用层序地层学原理、3D地震资料层拉平技术与三维可视化技术相结合方法，初步勾绘了古地貌的基本轮廓，研究了岩溶古地貌、古水系对岩溶缝洞碳酸盐岩储层的控制作用，分析了地貌单元对储层储集空间发育程度的影响。

We presented a novel approach for empty space skipping for object-order volume rendering. A two-staged space skipping was introduced: the first stage applied bricking on a regular grid, and the second stage used octree to reach a finer granularity.

提出一种针对物体空间为序体绘制的空域跳过算法：采用双层次空间跳过，先以规则的数据分块作粗略地跳过，再以八叉树获得更高粒度的优化。

After having been sequenced of the genomes in many species, one of the most advanced studies is to cytogenetically locate the DNA sequences to chromosomes, and construct integrated map combined the genetic map, contig map, chromosome banding pattern map, and cytogenetic map.

多种生物全序测定完成后，本领域最前沿的研究之一是将已测顺序进行细胞遗传学定位，作遗传图，重叠群图，染色体带型图和细胞遗传学图的整合图。

Since Tertiary, the global eustatic level kept falling while transgression in the SCS remained expanding, indicating that local sea-floor spreading and subsidence acted as a leading role in the study area.

本文根据南海东部石油公司提供的钻井岩芯和地震剖面资料，作了岩石地层学、层序地层学和地震地层学分析，识别出东沙、西沙和南沙的淹没事件。

HaNPV is the earliest commercial baculovirus insecticide in China and about 100, 000 hectare cotton farmland had been used such insecticide to prevent Heliothis armigera by the end of 1999. Many aspects of HaNPV such as the isolation and identification of different virus strains, bioassay of their toxicity, infectivity and duplication in culture cells, genome sequencing and some functional genes have been researched.

国内已对HaNPV进行了多方面的研究，包括病毒株的分离鉴定、形态特征、病毒生物活性测定、离体细胞感染和复制、测序和功能基因研究，基因工程病毒杀虫剂的构建等；但对其复制侵染与宿主细胞互作的分子机理，目前仍缺乏足够且深入的了解。

A shot-gun DNA sequence strategy was employed,in which the mitochondrial genome library of Muntiacus reevesi has been constructed to obtain the complete mitochondrial genome sequence.

通过建立麂属动物小麂线粒体DNA文库、鸟枪法测序，获得了小麂线粒体基因组全序列并对其基因组成、蛋白质的编码序列、tRNA基因等结构作了详细分析，这也是国内有关哺乳动物线粒体基因组全序列的首次报道。

Besides, performance tests were also conducted. Finally, the most practicable design was chosen to develop a shift-level control governor so that the wheelchair can freely move forward, backward and change its directions.

最后，选择一个最佳的可行设计，进行调速机构的设计与配置来作循序的档位切换控制，以提供单侧驱动轮椅可以自如地前进或倒退的行进和转向。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
