[Other] EMIandEMS DL : 0: 几乎所有设备的传导干扰都包含共模噪音和差模噪音，开关电源也不例外。共模干扰是由于载流导体与大地之间的电位差产生的，其特点是两条线上的杂讯电压是同电位同向的；而差模干扰则是由于载流导体之间的电位差产生的，其特点是两条线上的杂讯电压是同电位反向的。-almost all the equipment includes EMI common mode noise and differential mode noise, switching power supply is no exception. Common mode noise is due to current carrying conductor between the earth and the potential of the poor, Its characteristics are two lines of noise voltage is the same with the potential to; while differential mode interference is the result of current-carrying conductor of the potential difference, Its characteristics are two lines of noise voltage potential is the reverse of the same.

[Other] HashTableinDS DL : 0: 一：问题描述针对某个集体（比如你所在的班级）中的“人名”设计一个哈希表，使得平均查找长度不超过R，完成相对的建表和查表程序。二：基本要求假设人名为中国人姓名的汉语拼音形式。待填入哈希表的人名共有30个，取平均查找长度的上限为2。哈希函数用除留余数法构造，用伪随机探测再散列法处理冲突。三：实现提示如果随机函数自行构造，则应首先调整好随机函数，使其分布均匀。人名的长度均不超过19个字符（最长的人名如：庄双双（ZHAGN SHUANG SHUANG）。字符的取码方法可直接利用C语言中的tosacii函数，并可对过长的人名先作折叠处理。四：需求分析本演示程序是对哈希表的建立和查找进行演示，主要数据来自自己编写的人名“A~~Z”等字母组成，拼音由开头的字母组成的词组，查找时用伪随机探测再散列法处理冲突。随机产生人名的位置。具体的程序内容在源程序里面有比较详细的解析。程序的运行在下列有详细的介绍。 -one : Problem description against any collective (such as your own classes) of "names" design a hash table. you make the average length of not more than R, completes the construction and Lookup Table procedures. Two : the assumption that the basic requirements were known as the Chinese name of Chinese pinyin form. Hash Table question Enter the names of a total of 30, you take the average length of a maximum of two. Hash functions with a few exception I stay constructed using pseudo-random re-hash detection method to resolve disputes. 3 : Achieving suggested random function on its own if the structure should first be adjusted his random function, it evenly distributed. Names not on the length of more than 19 characters (the longest names such as : both Chong (ZHAGN SHUANG SHUANG).
