Hadamard matrix as an orthogonal matrix was investigated by Sylvester from 1867, possess important position in block design, it was used extensive in project and communication. The thesis has discussed the relation of Hadamard matrix and Walsh function as well as pseudo-random sequence.

Hadamard矩阵最早是作为正交矩阵由Sylvester在1867年开始研究的，在区组设计中占有重要地位，其广泛应用在工程和通信上；本文着重讨论了Hadamard矩阵和Walsh函数以及伪随机序列的关系，最后所得结论具有一定的理论意义和应用价值。

Because the DCOM have got to carry out the function superior, load equilibrium, safety, protocol irrelevant, permit the mistake, module to use with many times , expandible , haleness of the edition develop, position independent, the irrelevant of language and so on, the numerous advantage, and that make use of the DCOM can become the thin customer to carry, and the customer carry to only need to have a customer application to carry out and only need to have a midas.dll, and copy a soft disk these two applications.

由于DCOM有着执行性能优越、负载平衡、安全性、协议无关性、容错性、组件和复用、可扩展性、健壮的版本发展、位置独立性、语言无关性等众多的优点，而且利用DCOM可以形成廋客户端，客户端只需有一个客户端应用程序和一个midas.dll即可运行，将这两个程序拷贝到一张软盘即可。
