收集了几个android2.1相关的学习实例源码，ContentProvider主要使用系统的contentProvider。有与数据库相关的，比如ex08_2_SQLite，演示不用contentProvider,直接用裸sql进行操作。介绍DatabaseHelper.删除表的知道了，但是删除数据库的没有发现.还有其它的源码，学习不错，敬请下载。

comsol安装证书以及二氧化硅光纤模式图(COMSOL installation certificate)

为锁相回路或锁相环，用来统一整合时脉讯号，使内存能正确的存取资料。PLL用于振荡器中的反馈技术。 许多电子设备要正常工作，通常需要外部的输入信号与内部的振荡信号同步，利 用锁相环路就可以实现这个目的。(For phase lock loop or phase lock loop, the unification and the integration of the pulse signal used to when, make memory can correct access material. The technology used in PLL oscillator feedback. Many electronic equipment to be normal work, usually need to external input signal and internal oscillation signal synchronization, with the phase lock loop can achieve this goal.)
