This paper reviewed the developments in 2-D numerical model of the water flow. By means of the latest observation data of the prototype, the detailed analysis was made on the major thalweg, section, island and bottomland, the erosion and deposition of the river bed and the scour hole near the dock and the law of the fluvial process was obtained. Based on the related references, the evolution trend of the channel after the Three Gorges was finished was predicted. The 2-D mathematical model of the water flow was set up and validated using the latest data. With the model, the flow and velocity of several cases were calculated. The stability computation of the bank at the typical section under difference conditions was carried out by adopting the world widely used Geo-Slope slope stability analysis program. Finally, the synthetical evaluation on the influence of the project on the flood level, velocity, river circumstances, bank protection and flood prevention was made and the conclusion that the construction of the dock had little effect on the flood discharge was obtained.

本文介绍了平面二维水流二维模型研究进展，对河道历史演变概述，通过最新原型观测资料对河道近期主泓线、断面、洲滩、河床冲淤、码头附近冲刷坑等进行详细分析，总结近期河道演变规律，并参考有关文献，对三峡建成后河道演变趋势进行预测；建立了平面二维水流模型，并根据最新资料对模型进行率定和验证，采用模型对几种工况组合进行壅水和流速计算；采用国际上广泛应用的Geo-Slope滑坡稳定分析程序对几种工况条件下工程断典型断面岸坡进行稳定性计算；最后总结工程建设对洪水位、流速、河势、堤防及防洪抢险等方面进行综合评价，得出码头建设对行洪影响较小的结论。

CT scans were performed with 10 millimeter thick section,125 kVp,250mAs,from the apexes to lung bases,then the targed areas were scaned with 1.5 to 2.0 millimeter section,125kVp,250mAs.

From high resolution magnetostratigraphic study of the Meishan section of Changxing County, Zhejiang Province, the following conclusions are obtained:(1) The Meishan section can be divided into five normal polarity subzones and four reversed polarity subzones.

通过对浙江长兴煤山剖面的高分辨率磁性地层学研究，得出以下结论：（1）浙江长兴煤山剖面可划分为5个正向极性亚带和4个反向极性亚带。

Detecting each marker and cmparison the location of sequential tissuesection could determine the area loceation relationship of the markers, but it is difficulte to determine their correlation intra-cells exactly. No report of detecting virus genome and antigenes on a one section with triple staning techniques exists in the lit erature. in this report. by combining immunohistochemistry and in situ hybridization (with dioxigenin labelled HBV DNA probe), a triple staining technigce was established. With this technic, on one formalin-fixed and paraffin embeded section, HBV DNA, HBsAg and HBcAg were determinated one after the other.

各个细胞内病毒的复制和表达水平以及与肝细胞病变的关系，是乙型肝炎发病机理研究的一个重要方面：目前常用的在系列切片上对各标志物分别检测，比较观察的方法，一般只能大致了解各待检物在某一区域的定位关系，很难准确地了解它们在同一细胞内的关系：国内外尚未见有在同一张切片上三重标记染色检测病毒核酸及其多种抗原的报道：本文结合免疫组织化学ABC法及地高辛配基标记HBV DNA探针原位杂交，建立三重标记染色技术：在一张福尔马林固定石蜡包埋肝组织切片上先后检测，同时显示HBV DNA、HBcAg和HBsAg。

The result is that the whole one kilometer depth of the reef, from what had been its shallowest section to its deepest section, is now exposed for examination.

其结果是，整个一公里深的珊瑚礁，从被其浅水节最深切的部分，现在暴露等待检测

In Section 4.1 and Section 4.2, delay SEIR and SEIRS epidemic disease models with vertical transmission and pulse vaccination are discussed, respectively.

第一节和第二节分别讨论了具有垂直传染和脉冲免疫的时滞SEIR及SEIRS传染病模型。
