Concrete components have flaws, such as loose, hole, slit band and so on. These flaws not only lead to the change of acoustic velocity, but also have strong absorption and attenuation action to the acoustic wave. It is an effective method to detect engineering quality of concrete components by using acoustic velocity CT and attenuation CT combined detection technology.

混凝土构件中存在的诸如松散、空洞、缝隙夹层等缺陷，不仅造成声波速度的变化，而且对声波具有较强的吸收衰减作用，利用声波速度CT和衰减CT联合检测技术是检测混凝土构件工程质量的有效方法。

Secondly, the web-based remote monitoring and diagnosis system is studied, and then the architecture of remote monitoring and diagnosis system is established in integrated environment of Infranet / Intranet / Internet and the integration methods of information in these environment is discussed, at the same time, the model architecture and key techniques of remote collaborative diagnosis are studied/Then a kind of remote monitoring and diagnosis system model based on mobile agent is established, and the system realization methods are discussed on IBM Aglet platform.

本文首先阐述了国内外远程监测诊断系统的研究现状和发展趋势；其次，在分析了目前制造装备远程监测诊断模式存在不足的基础上，并在Infranet／Intranet／Internet集成环境下，提出了基于Web的制造装备远程监测诊断系统的体系结构，探讨了系统的信息集成方式；然后对远程协同诊断技术以及如何将移动Agent用于制造装备远程监测诊断系统进行了研究，并以IBM的Aglet平台为例论述了系统的实现方法。

But,the drawbacks of Shewhart's control chart is that when the control chart shows abnormal,it cannot tell us what and where is the assignable cause,i.e.it cannot diagnose the abnormalityof the process.In 1982,Prof.Gongxu Zhang proposed the diagnosis theory with two kinds ofquality,solved the diagnosis problem of assignable cause,thus opened a new direction ofstatistical diagnosis theory and developed the theory of SPC into a new stage ofSPCD(Statistical Process Control and Diagnosis).The multi-operation and multi-index system exists everywhere,in general,nearly all theproduction lines of factories belong to this system.

但休哈特控制图的缺点是，当控制图显示异常时，它不能告知是何原因、何处发生了异常，即不能诊断。1982年，我国著名质量管理专家张公绪教授提出两种质量诊断理论，解决了对异常因素的诊断问题，开辟了统计诊断理论的新方向，将质量控制推向了一个新的发展阶段——统计过程控制与诊断阶段。

According to our present broadcasting situation,the thesis proposes using new technology to update and reform the present HFC. It also suggests broadcasting using self-advantage and arranging EPON in order to win the supermarket.

A new general kinetic equation was derived in which the effect of the removal of condensation water was taken into account completely, and was applied to the polyesterification kinetic study of AA/HPHP and AA/NPG. It was found that the reaction order of self-catalyzed polyesterification was not constant. For these polyesterifications, the reaction order was 2.5 at a low temperature, while 3.0 at a high temperature.
