在传播中

With eggs and children artemia were detedcted using nested-PCR. WSSV positive products could be detected in artemia, and DNA sequence of the product accords with the designed specific amplified one according to sequence analysis. The positive rates of wild brine shrimp and filial generation were 58% and 43%, respectively. However, it seems to be no regularity between parents and filial generations positive results. It may not judge whether WSSV could vertically transmit in artemia or not.

检测结果显示：卤虫中可扩增出特异性的、与引物设计吻合的DNA片段；DNA测序分析表明，扩增片段的DNA序列与白斑综合症病毒序列一致；野生卤虫携带白斑综合症病毒的阳性率为58％，实验条件下野生卤虫的后代的阳性率为43％；同一卤虫家系中，亲代与子代携带病毒的情况不完全一致，不能确定白斑综合症病毒可否通过繁殖在卤虫世代间进行垂直传播。

Hit CCTV from 2001 " laugh be proud all corners of the country " pilfer edition sound begins like goods, in triumphant throw nearly 10 million yuan every year to undertake thought fors the time being, and gain ground as what work of movie and TV travels in Internet, original tone is serious like product sale atrophic, in the centre of gravity of edition of triumphant blow pilfer also turned to a network from phonic resembling goods.

从2001年打击央视《笑傲江湖》的盗版音像制品开始，中凯每年投入近1000万元进行维权，而随着影视作品在互联网传播的普及，正版音像制品销售量严重萎缩，中凯打击盗版的重心也从音像制品转向了网络。

But the symmetric axis of TI formation is parallel to the borehole axis in the thesis, the propagation velocity of SV-wave and SH-wave are the same in vertical direction, we can't see the splitting phenomena of shear wave.

本文中地层对称轴和井轴平行，SV波和SH波在竖直方向上的传播速度是相同的，本文地层模型下的井孔中是观测不到横波劈裂现象的。

With a clear understanding of theory and large numbers of facts, this article analysis the following problems by the view and method called materialist dialectics. First, the concept of information ethics is established when the moment people's life style begins to change in Information Age, with understanding of both the basic principle of moral life and moral problems existing in our society and have knowledge scope range from social practice to abstract theory. Second, the essence and forming rules of information ethics is revealed with the help of studying some basic questions and debating some characteristics from the philosophy point of view. Third, the further analysis of the system formula and social function is founded on debating the theory, which forms the system from the ethics point of view.

本文在梳理理论文献和掌握大量实证材料的基础上，以唯物辩证法的观点和方法为指导，对以下问题进行了分析和讨论：一、从信息时代人们生存方式的变迁入手，明确社会道德生活的基本要求，在认清信息社会存在的道德问题的基础上，从社会实践到理论抽象，确立了信息伦理观念；二、从哲学的角度出发，研究信息伦理生成的基本理论问题，在厘定相关概念的基础上，讨论了信息伦理的特点，揭示了信息伦理的本质及其生成规律；三、从伦理学的角度出发，在讨论构建信息伦理体系的理论依据的基础上，进一步分析了信息伦理的体系结构和社会功能；四、从社会实践的角度出发，研究信息伦理在信息传播过程中的应用问题，从理论回到实践，提出了较为系统的信息伦理原则和信息道德规范。
