VB实现Listview全选、多选功能

发射部分采用锁相环式频率合成器技术， MC145152和MC12022芯片组成锁相环，将载波频率精确锁定在35MHz，输出载波的稳定度达到4×10-5，准确度达到3×10-5，由变容二极管V149和集成压控振荡器芯片MC1648实现对载波的调频调制；末级功放选用三极管2SC1970，使其工作在丙类放大状态，提高了放大器的效率，输出功率达到设计要求。-Part of the launch phase-locked loop frequency synthesizer using technology, MC145152 and MC12022 PLL chips to lock in the exact carrier frequency 35MHz, the output carrier to achieve the stability of 4 × 10-5, reaching the accuracy of 3 × 10-5 by the varactor diode V149 and integration to achieve MC1648 chip VCO FM modulation on the carrier selection transistor amplifier at the end of class 2SC1970, to work in the C state to enlarge and improve the efficiency of the amplifier output power to meet the design requirements.

这个是Haffman的实现方法，也就是还可以的代码，希望采纳，^_^-this is the method, which is also the code, adopted ^ _ ^
