This thesis starts with analysis of the practical advantages of electronic business comparing with the traditional ones and the basic conditions of developing electronic business. It claims that taxation is a difficult point of electronic business, and points out fell main problems of taxation on the reference of methods of basic problems coped with electronic business by some international organizations and governments. On the base of this, it attempts to point out the basic clues of resolving the problems in commercial taxation of China today and our counter-measures and suggestions. And this can serve for the administration of taxation in China, promoting it to link with internation as soon as possible and become one of the strong countries, which is internationlization ineconomic information.

本文从分析电子商务与传统商务相比较的现实优越性及发展电子商务的基本条件入手，认为税收问题是电子商务的难点；并通过借鉴国际组织和各国政府对电子商务税收问题的基本处理作法，进一步提出电子商务中的几个主要税收问题；在此基础上，通过借鉴国际上对电子商务税收问题处理的基本经验和作法，试图提出解决现阶段我国电子商务税收问题的基本思路和应采取的对策与建议，以期使我国税收管理尽快与国际相接轨，迎头赶上国际经济信息化发展的新浪潮。

First of all, the gradual reform conditions that the "dual" roads dependence have lead to "short-sighted view" and "darkness" of the design of system of social insurance; Secondly, it comes from the restrictions of resources and systems set by the governmental organizations; thirdly, the internal contradictions of the government itself that caused by its self-benefit and irrationalness have made the performance of governmental responsibilities become a "dual game" and there are tropisms of internal "centralization" and external "being enterprises".

The experimental result shows that after reclaiming the tailings with garbage fertilizer, Leucaena leucocephala Dewit. can grow well on the tin-zinc tailings pond while it is restricted in the tailings ponds without any reclamation; the contents of As, Pb and Zn in Leucaena leucocephala Dewit. are not high, only a little above those in normal plants.

试验结果表明：在用垃圾肥对尾砂进行改良之后，银合欢能在锡锌尾砂库上较好地生长，而在未经过任何改良的纯尾砂库上则明显受到抑制；银合欢不同组织中的As、Pb、Zn含量均不高，仅略高於一般植物的背景值。

Histologically,the resected tumor was composed of epithelioid cells,without vascular or lipomatous component,and was characterized by HMB45 positive on immunohistochemistry.

The saponin is higher when growing on 6,7-V than that growing on MS and lumination was apt to stimulating saponin synthesis comparing with darkness.

生长在6，7-V基本培养基上的黄芪愈伤组织中黄芪皂苷含量比MS培养基上的高，而且光照比黑暗更有利于黄芪皂苷合成。

To acquire more information about gene expression at the whole-genome scale,our lab and National Engineering Center for Beijing Biochip Technology worked together and constructed the first genome-wide oligonucleotide microarray of the silkworm.This microarray was used to detect gene expression of 10 tissues/organs,including midgut,integument,head,hemocyte,testis,ovary,anterior/median silk gland,posterior silk gland,fat body and malpighian tubule.In this study,we performed analysis of these microarray data and confirmed the reliability of the results.
