One of these missions , a satellite called aeronomy of ice in the mesosphere , or aim , was launched in april to study so - called noctilucent clouds ( depicted above ) , the highest layer of clouds in the atmosphere 任务其一，今年4月该局发射了一颗名为“中层大气高空冰探测” （简称aim ）的卫星以研究所谓的夜光云（如上图所示）这是大气层中最高处的云层。

Then this paper designs the client / server / server frame which suit to this system , and uses the oracle8i database as the background database , oracle9i application server as the application server on mesosphere . in addition , this system achieves the connection between database and application server by jdbc , makes java server page as the exploitive tool . in this way , this paper establishes an experimentation e - business system that realizes intercommunion of the produce data in machine enterprise 接着，以client / server / server三层结构应用模式为基础对企业的应用构架作了设计；以oracle8idatabase作为后台数据库； oracle9ias作为中间层的应用服务器；采用java的jdbc技术实现了应用服务器与数据库服务器的连接；并以jsp作为系统前台开发工具，建立起了一个面向机械制造企业生产数据交换的企业内部的实验性质的电子商务平台。

In section one , by using fice scheme and time - gcm , a model of trace gases and oh airglow affected by gravity wave is set up , then the propagation of nonlinear gravity wave and the effect on trace gases and oh airglow are analyzed . the result shows gravity wave excited by tropospause forcing can propagate stably to the mesosphere through the stratosphere so that energy and momentum can be transferred from one region to another . in this process , gravity wave undergoes growth , overturning , convection and breaking 在第一部分的工作中，利用全隐欧拉格式和全球热层-电离层-中间层-电动力学环流耦合模式（ time - gcm ） ，对重力波的非线性传播及其在传播过程中对中高层大气中氧族和氢族成分和与之密切相关的oh气辉辐射的影响进行了数值模拟，结果表明，从对流层向上传播的重力波经历了产生、发展、饱和、对流产生直至破碎的非线性演化，大气的非等温结构加速了重力波在中层顶区的破碎，重力波的非线性传播是小尺度对流和湍流产生的一个重要的源。

A experienced equation which is summarized by many experiments is used to determine the number of mesosphere nerve cell and a sort of new square - sum function of errors is adopted . its characteristic is that weight errors of possible exceptional point is less . accordingly , the effect of errors of possible exceptional point is reduced , which make actual function relation simulation easier 本系统针对bp算法的局限性，给出了一种优化的bp算法，采用经过大量实验总结出的经验公式来确定隐层神经元的个数，并选取了一种新的误差平方和函数，该函数的特点是对一些可能的异常点的误差权值设计的较小，从而降低了异常值误差带来的影响，便于模拟出真实的函数关系。

Instructional technology is not only a technological or educational problem , but also a societal , one instructional technology has deep sociological meaning on macroscopical social change and social control , on mesosphere social stratification and educational equality , on microcosmic social interaction and human socialization 摘要教育技术并非仅仅是“技术”问题、 “教育”问题，也是一个“社会”问题；教育技术在宏观层面的社会变迁、社会控制，中观层面的社会分层、教育机会均等，微观层面的社会互动、人的社会化等问题上，都有深刻的社会学意涵。
