It is well known that the multi-value CDMA spreading codes can be designed by means of a pair of mirror multi-rate filter-banks based on some optimizing criteria. The dissertation indicates that there exists a theoretical bound in the performance of its circular correlation property, which can be described by an explicit expression.

研究了基于两带镜像多速率滤波器组来设计的多值CDMA扩展码的方法，并推导出了基于这种方法设计的码序列在循环相关特性方面所能达到的极限，以及达到此理论极限时应满足的条件；在此基础上，提出了一种基于熵最大化准则来产生CDMA扩展码的设计方法。

The first part introduces the basic theory of Circulatory Economy.

The setting of inertial coefficient has led to the problem of "log i c circulation"in Newton mechanics.

"逻辑循环"是指在一种理论中存在的互为前提，互为因果的逻辑矛盾。

On the other hand, with the theory of circular economy and continuable development brings out, people pay more attentions to the disposal of the MSW which is available as resourse. As a result, the research on condign disposal of MSW is very significative for the recycle when the MSW has been disposed harmlessly.

另外，随着循环经济和可持续发展理论的产生，人们对生活垃圾处理更加注重资源化，因此，研究适宜的垃圾处理技术路线，使生活垃圾在无害化处理的前提下得到最大程度的利用，已成为十分有意义的课题。

Fourthly, according to the theory of circular economy, the paper tried to provide an effective and feasible process flow of EOL vehicles. After taking into account of the situation in China, the paper also tried to establish an EOL vehicles recycling system which is represented by automaker integrative mode. The system is not only congruous with the Extended Producer Responsibility Policy, but also beneficial to integrate numerous enterprises and individuals among the auto industry chain.

第四，结合我国汽车产业供应链模式，遵照循环经济理论，尝试提供一套有效可行的报废汽车处理流程，并在充分考虑我国现阶段国情的基础上，构建了以汽车制造商一体化模式为代表的报废汽车回收体系，使之既符合国家对汽车制造商提出的"生产者责任制"政策，又能利用汽车制造商在产业供应链中的领导地位，将众多企业或个体有效集结起来。

The technologies used to solve these problem is presented. The second part proposes a new access method of recycle links of internal speed-up space switching fabrics. It eliminate the main contrariety between network performance and complexity. Combined with dilated Banyan, two types of recycled Banyan network-expanded recycle dilated Banyan and recycle dilated Banyan network are developed.

第二部分提出一种循环线接入方式，使得反馈线数目不再成为交换网络的性能/复杂度的矛盾所在；并结合线群Banyan网形成RDBN交换结构，对RDBN在均匀和非均匀业务模型下的性能进行了理论分析和计算机仿真，得出参数的选择尺寸，并提出使用窗口重整算法以保证信元序列完整性。

The preventive measures for the harmful defects of alkali metals are as follows: 1, reducing the alkali metals content in the raw materials; 2, increasing the MgO content of the sinter , decreasing the basicity of slag , decreasing the Si content of the pig iron, increasing relative slag volume; 3 , introducing prereduced ore pellets or partly reducted sinter; 4increasing the ability of coke resisting alkali metals; 5, using refractories that have the ability of resisting corrasion of alkali metals; 6 , cleaning the blast furnace periodically. The above recommendations are necessary for decreasing the circulation and accumulation of alkali metals effectively in blast furnace, reducing the harmful influence of alkali metals on blast furnace, increasing the smelting intensity, decreasing the coke rate, improving the gas permeability.

基于碱金属对高炉冶炼的上述危害，本文结合湘钢高炉的实际生产情况，通过理论分析、计算以及其他钢厂防治碱害的经验，提出防治高炉碱害的措施：1、减少入炉原、燃料的碱金属含量；2、提高烧结矿中的MgO含量、降低炉渣碱度、降低生铁含硅量、适当增加渣量；3、采用预还原的金属化球团或部分还原的烧结矿；4、提高焦炭的抗碱能力；5采用抗碱侵蚀的耐火材料；6、周期性性洗炉，以有效地减少碱金属在高炉内的循环富集，降低碱金属对高炉的危害，提高高炉的冶炼强度，降低焦比，改善高炉透气性。

The intensity of the action of cortisol and the sensitivity of the results to important parameters are discussed.

讨论了皮质醇作用的强度及其它再循环参量的取值范围及理论结果对参数的敏感性。
