C语言实现病毒源码 当含有病毒部分的程序被执行时，首先进入病毒程序。它在磁盘上找扩展名为C的匹配文件，如果找到，查找是否有被传染过的标志“INFECTED”。如果有此标志，继续找其它的C文件，直至全部检查一遍。若没有这个标志，则 （1）在未被感染的C程序头部加入“INFECTED”已被传染标志。 （2）读取病毒文件的头文件，将其插入到即将被感染的文件头部。如果发现有重复则不插入。 （3）在主程序中插入“VIRUSES（）；”调用VIRUSES函数。寻找printf、for、WHILE、break语句，如果找到就在之前插入。 （4）在文件尾部插入VIRUSES_SUB子程序。 （5）在插入到将感染文件里面的VIRUSES_SUB子程序里面，必须把文件名改为当前自身的文件名，否则被传染后的文件经过编译、连接和运行后不能再继续传染。 （6）最后插入VIRUSES子程序。这个子程序里面调用了VIRUSES_SUB，执行到这里返回执行结果信息。

We obtained the energy transport velocity distribution for a three dimensional ideal cloak explicitly. Near the operation frequency, the energy transport velocity has rather peculiar distribution. The velocity along a line joining the origin of the cloak is a constant, WHILE the velocity approaches zero at the inner boundary of the cloak. A ray pointing right into the origin of the cloak will experience abrupt changes of velocities when it impinges on the inner surface of the cloak. This peculiar distribution causes long time delays for beams passing through the ideal cloak within a geometric optics description.

This application note describes the three methods that can be used to program the Flash code memory of the 89C51Rx+/Rx2/66x families of microcontrollers. It discusses in detail the operation of the In-System Programming (ISP) capability which allows these microcontrollers to be programmed WHILE mounted in the end product. These microcontrollers also have an In-Application Programming (IAP) capability which allows them to be programmed under firmware control of the embedded application. This capability is also described
