C語言實現病毒源碼 當含有病毒部分的程序被執行時，首先進入病毒程序。它在磁盤上找擴展名為C的匹配文件，如果找到，查找是否有被傳染過的標志“INFECTED”。如果有此標志，繼續找其它的C文件，直至全部檢查一遍。若沒有這個標志，則 （1）在未被感染的C程序頭部加入“INFECTED”已被傳染標志。 （2）讀取病毒文件的頭文件，將其插入到即將被感染的文件頭部。如果發現有重復則不插入。 （3）在主程序中插入“VIRUSES（）；”調用VIRUSES函數。尋找printf、for、WHILE、break語句，如果找到就在之前插入。 （4）在文件尾部插入VIRUSES_SUB子程序。 （5）在插入到將感染文件里面的VIRUSES_SUB子程序里面，必須把文件名改為當前自身的文件名，否則被傳染后的文件經過編譯、連接和運行后不能再繼續傳染。 （6）最后插入VIRUSES子程序。這個子程序里面調用了VIRUSES_SUB，執行到這里返回執行結果信息。

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
