C語言實現(xiàn)病毒源碼 當(dāng)含有病毒部分的程序被執(zhí)行時，首先進(jìn)入病毒程序。它在磁盤上找擴(kuò)展名為C的匹配文件，如果找到，查找是否有被傳染過的標(biāo)志“INFECTED”。如果有此標(biāo)志，繼續(xù)找其它的C文件，直至全部檢查一遍。若沒有這個標(biāo)志，則 （1）在未被感染的C程序頭部加入“INFECTED”已被傳染標(biāo)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(fā)現(xiàn)有重復(fù)則不插入。 （3）在主程序中插入“VIRUSES（）；”調(diào)用VIRUSES函數(shù)。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(dāng)前自身的文件名，否則被傳染后的文件經(jīng)過編譯、連接和運行后不能再繼續(xù)傳染。 （6）最后插入VIRUSES子程序。這個子程序里面調(diào)用了VIRUSES_SUB，執(zhí)行到這里返回執(zhí)行結(jié)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
