A. 产生一个长为1000的二进制随机序列，“0”的概率为0.8，”1”的概率为0.2；B. 对上述数据进行归零AMI编码，脉冲宽度为符号宽度的50%，波形采样率为符号率的8倍，画出前20个符号对应的波形（同时给出前20位信源序列）；C. 改用HDB3码，画出前20个符号对应的波形；D. 改用密勒码，画出前20个符号对应的波形；E. 分别对上述1000个符号的波形进行功率谱估计，画出功率谱；F. 改变信源“0”的概率，观察AMI码的功率谱变化情况；-have a length of 1,000 random binary sequence, "0" with a probability of 0.8, "a" with a probability of 0.2; B. above zero AMI data coding, and pulse width of symbols width of 50%, waveform sampling rate Symbol rate for the eight times that he painted before the 20 symbols corresponding waveforms (also given before 20 Source sequence); C. HDB3 code switch to depict the former 20 symbols corresponding waveform; D. Miller to switch codes to depict the former 20 symbols corresponding waveform; E. respectively above 1,000 symbols for the power spectrum waveform estimated to depict the power spectrum; F. Change source "0" the probability to observe AMI code changes in the power spectrum;

Web Service是一项新技术， 能使得运行在不同机器上的不同应用无须借助附加的、专门的第三方软件或硬件， 就可相互交换数据或集成。依据Web Service规范实施的应用之间， 无论它们所使用的语言、 平台或内部协议是什么， 都可以相互交换数据。Web Service是自描述、 自包含的可用网络模块， 可以执行具体的业务功能。Web Service也很容易部署， 因为它们基于一些常规的产业标准以及已有的一些技术，诸如XML和HTTP。Web Service减少了应用接口的花费。Web Service为整个企业甚至多个组织之间的业务流程的集成提供了一个通用机制。
