The traditionary linear power amplifier has been washed out for its low efficiency and big size.传统的线性功率放大器由于效率低，体积大，因而已经被淘汰。
The traditionary design of process planning was optimized and expanded through this model, while the resource of design and manufacture was integrated better.通过此模型优化，扩展了传统的工艺设计模式，更好地实现了设计资源与制造资源的集成。
