rundll32.dll很多人误删，在网上却很难找的小DLL，在XP中使用。-rundll32.dll many people mistakenly cut on the Internet is very difficult to find a small DLL, the use of XP.

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.

自己做的第一个C++小游戏，就是纸牌接龙。用的最原始的控制台程序写的。玩起来比较纠结，因为字体太小，而且花色不太好辨认！（但是可以在控制台窗口中进行字体设置。）输入的时候一定要输入整数，因为没有设置纠错机制。希望大家多多支持哈！
