传播

Finally the article integrate all kinds of essential and expound characteristic oftwo-way communication——which called emanative way and congregate way —— forZhixin dwelling's information.

最后综合各种要素，阐述了有关智新民居信息传播的双向性特征——发散性传播和集聚性传播。

We have performed systematical studies on intrauterine transmission of hepatitis B virus and our studies suggested that HBV may occur through progressive infection of different placental layers until the virus reaches the fetoplacental circulation, which is the named "transplacental cellular traffic" except through placental tears with transfusion of infected maternal blood into the fetal circulation, which is the named "hematogenous transmission".

我室近年来对HBV宫内传播进行了系列研究，发现了胎盘在宫内传播中的作用，并提出了HBV宫内传播机制的假设：除血源性途径外，还可通过HBV在胎盘组织内的&细胞传递&途径，即HBV可以从母体蜕膜细胞通过&逐层转移&至胎儿绒毛毛细血管内皮细胞，导致胎儿感染。

Reults there 90 pregnant and lying-in women positive for hiv in shenzhen city were detected, and 74 of them were acquired the infection through sexual activity, accounted for 82.2% including 57.8% of them frough extramarital sexual behavior.. there 82 perosons accepted the intervention by health institutions occupied 91.1％. vertical transmission occurred to casesand one of them died.

结果 深圳市共通过预防与控制艾滋病母婴传播项目途径发现90例hiv感染孕产妇，性途径传播74例，占82.2％，其中非婚性行为占57.8％；有82例接受卫生机构提供的干预措施，占91.1％，8人失访或回原籍；暂发现2例母婴传播病例，均为产后发现感染的产妇生产，其中1例已死亡。

Based on theories of geometrical optics and electromagnetic wave promulgation, models of three status of aqueous foams transit by light were set up, and the situations of mono- and double- layer unassimilated, assimilated and electric solid infusible materials were investigated for the changes of orientation, path and energy distribution of ray.

基于试验结果，利用几何光学原理和电磁波传播理论，建立了水基泡沫三种状态下的消光模型，通过理论分析和数值模拟，研究了单层界面无吸收、双层界面无吸收、有吸收和含导电性固体不溶物情况下的光线传播规律，从光线传播方向和能量的变化方面，揭示了水基泡沫消光的机理及其对目标探测和甄别的影响。

Firstly, the dissertation looks back the development of science and technology and the evolvement of mode of information communication, showing the change of knowledge innovation system and the influence netlike information has upon the knowledge innovation system from three aspects, which are action model, organization structure and thinking method.

随着科学技术的发展，信息传播方式随之演进和发展，而信息传播的发展，特别是网络传播的兴起和发展，不仅对科学技术的发展产生影响，也带来了知识创新系统的变化和发展，特别是知识创新的活动方式、组织结构和思维方式都发生了巨大的变化。

The types of communication are roughly nonvocal and vocal communication.

传播的类型大体上分非语言传播和语言传播。

Thirdly, from the influences of Media Event, by reference to objective reporting ideas, this study analyzes in sequence these influences in terms of reporting practice, media management and control, and reporting ideas, to further explore how two aspects remodify themselves and coordinate to supplement, and perfect the system of news reporting ideas.

具体而言，一是从媒介事件的本体出发，在&媒介事件&同名概念的已有研究基础上，对本研究中的媒介事件加以概念上的厘清与界定，并将其框定在新闻报道理念及实践的双重层面中，从不同角度探讨&如何&呈现出&传媒→事实→报道&的新闻生产及传播关系；二是从媒介事件的历史出发，实际上是放置于新闻报道发展史中，解答&为何&繁衍出这种新闻传播现象并导致这种新闻生产及传播关系的问题；三是从媒介事件的影响出发，以客观报道理念为参照，分别从报道实践、传媒管理与控制、报道理念等角度对媒介事件的影响进行逐一辨析，考察媒介事件和客观报道理念如何各自修正并互为补充，从而进一步完善新闻报道理念体系。

This paper discusses some application cases of the error propagation law by the examples of trigonometrical survey, and presents that not only sum function and numeral multipling function in which there is only one independent observed value but also more complex functions which are equal in mathematics are not opposite in the process of error propagation according to the error propagation law.

1引言本文以三角测量为例，对误差传播定律一些应用问题进行了讨论，指出当只有一个独立的观测值时，和函数与倍数函数运用误差传播定律不会出现悖论；如果在测量工作中有多余的直接观测值，就需用平差后的间接观测值按协方差传播律来计算，这样数学中相等的函数关系才能得到同样的函

Globalization brings us high technology of information and transportation. It disorganizes the boundary of cultures and the interculturai communication becomes a life style.

全球化所带来信息技术、交通运输的突飞猛进，瓦解了文化传播的边界和防护系统，使跨文化传播日益成为人们日常生活方式，并且这种传播方式日益从个人实际互动层面扩展到超地方的、非面对面的互动，即个人与媒介文本的意义解读层面。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
