Shell viruses wrap themselves around a host program and don't modify the original program．Shell programs are easy to write，which is why about half of viruses are of this type．
外壳型病毒将它们自己包裹在主程序的四周，对源程序不作修改。 外壳型病毒容易编写，这也正是约有一半病毒程序是这种类型的原因。
The virus program is embedded into the host program and depends on the execution of the host program.
病毒程序嵌入到宿主程序中，依赖于宿主程序的执行而生存，这就是计算机病毒的寄生性。
Once attached to the host program, the viruses then look for other programs to "infect".
病毒程序一旦附加到一个主程序上，就开始寻找其他可以进行“感染”的程序。
Meanwhile, a method of dynamically allocating symbol IDs for plug-ins by host program is brought forward to put an end to name repeating phenomenon.
同时，为了解决插件标识中的重名现象，提出了由宿主程序动态分配ID的方法，杜绝了重名的风险，降低了系统与插件间的耦合度。
According to test flow, the host program and its partial code are given, and according to the hardware structure of switch matrix, the firmware of each part is also given.
根据测试流程，给出了主机控制程序设计及部分实现代码，并针对开关矩阵硬件构成，分别给出了各个组成部分的固件程序代码。
Two, engineering selection: host selection of the entire heat recovery modular ground-source heat pump units, engineering design provided by the host program manufacturers.
工程选型：主机选用全热回收模块式地源热泵机组，工程设计由主机厂家提供方案。
The host program takes on the complex computational tasks such as parameter adjusting and the waveform data subdividing, which simplifies the circuit for the peripheral unit.
将参数调整，波形数据细分的复杂计算任务交于主机程序完成，简化了外设执行部件的电路结构。
Worms: A self-replicating, self-contained program executes without user intervention. Worms create copies of themselves, and they don't require a host program to infect a system.
蠕虫：一个执行时无需用户介入，自我复制的独立程序。蠕虫创建自身拷贝，并且它们不需要宿主程序来感染系统。
