电路 电路或电网络由以某种方式连接的电阻器，电感器和电容器等元件组成。如果网络不包含能源，如电池或发电机，那么就被称作无源网络。换句话说，如果存在一个或多个能源，那么组合的结果为有源网络。在研究电网络的特性时，我们感兴趣的是确定电路中的电压和电流。因为网络由无源电路元件组成，所以必须首先定义这些元件的电特性。就电阻来说，电压-电流的关系由欧姆定律给出，欧姆定律指出：电阻两端的电压等于电阻上流过的电流乘以电阻值。在数学上表达为： u=iR (1-1A-1)式中 u=电压，伏特；i =电流，安培；R =电阻，欧姆。纯电感电压由法拉第定律定义，法拉第定律指出：电感两端的电压正比于流过电感的电流随时间的变化率。因此可得到：U=Ldi/dt 式中 di/dt =电流变化率，安培/秒； L =感应系数，享利。电容两端建立的电压正比于电容两极板上积累的电荷 q 。因为电荷的积累可表示为电荷增量 dq 的和或积分，因此得到的等式为 u=，式中电容量 C 是与电压和电荷相关的比例常数。由定义可知，电流等于电荷随时间的变化率，可表示为 i = dq/dt。因此电荷增量 dq 等于电流乘以相应的时间增量，或 dq = i dt，那么等式(1-1A-3)可写为式中 C =电容量，法拉。

The mental function of white is in it the hair the exhibition process in order to symbolizing again under the influence of political function rotting, reaction, fall behind, if see as"white particularly road";Its also symbolizing failure, birdbrain and hasing no benefit can get, if fail in the war of a square always beats "flag of surrender" to mean to surrender, calling the intelligence lowly artificial"idiocy", lift a hand to but can not get an advantage or didn't be effective to be called to"work in vain","labor in vain","white stem" etc., it still symbolizes crafty evil,阴 insurance, such as"sing white face","white face" master of intrigues;End, it still symbolizes knowledge superficial, have no merit and fame, if call a civilian common people for"illiterate person","white dress","white body", lack to toughen, the experience not deep scholar call "scholar inexperienced in worldly affairs" etc..

白色的心理功能在其发展过程中由于受到政治功能的影响，又象征腐朽、反动、落后，如视为"白专道路"；它也象征失败、愚蠢、无利可得，如在战争中失败的一方总是打着"白旗"表示投降，称智力低下的人为"白痴"，把出力而得不到好处或没有效果叫做"白忙"、"白费力"、"白干"等，它还象征奸邪、阴险，如"唱白脸"、"白脸"奸雄；最后，它还象征知识浅薄、没有功名，如称平民百姓为"白丁"、"白衣"、"白身"，把缺乏锻炼、阅历不深的文人称作"白面书生"等。

Through the source code audit such as RATS software can find the flaw information of level of partial source code, but after all the majority that software of source code audit searchs spills over for the existence buffer such as Strcpymemcpy the C function that involuntary discharge of urine has, the measure that adopts audit source code so will undertake flaw is dug is coefficient of a possibility very small leak digs a technology, and the flaw that although also can find a few software,checks in the light of the black box of software, but possibility coefficient also is met lesser, a few undertakes flaw is dug idea that are in abroad already slowly promotion writes black box to check code for oneself, the module of a certain function that is aimed at system or software next undertakes modular flaw digs a technology.

通过RATS等源代码审计软件可以找到部分源代码级别的漏洞信息，但是究竟源代码审计软件寻找的多数为strcpymemcpy等存在缓冲区溢出遗患的C函数，所以通过审计源代码的办法来进行漏洞挖掘是一个可能性系数很小的漏洞挖掘技术，而针对软件的黑盒子测试虽然也能找到一些软件的漏洞，但可能性系数也会较小，在国外的一些进行漏洞挖掘的办法已经慢慢的提升为自己写黑盒子测试代码，然后针对系统或软件的某个功能模块进行模块化的漏洞挖掘技术。
