锁相回路可视为一个输出相位和输入相位的回授系统用以同步输入参考讯号和回授后输出信号。并让其操作同样的频率。如(图一)所示，简单锁相回路[3,4]是由三个电路构成，分别为相位侦测器（Phase Detector）、回路滤波器（Loop Filter）、压控荡器（VCO）

USB海量存储设备类规范包括四个独立的子类规范：(ATA command的那个没有) ①USB Mass Storgage Class Control/Bulk/Interrupt(CBI)Transport ②USB Mass Storage Class Bulk-Only Transport ③USB Mass Storage Class ATA Command Block ④USB Mass Stroage Class UFI Command Specification。 前两个子规范定义了数据/命令/状态在USB上的传输方法。 Bulk-Only传输规范仅仅使用Bulk端点传送数据/命令/状态， CBI传输规范则使用Control/Bulk/Interrupt三种类型的端点进行数据/命令/状态传送。 后两个子规范定义了对存储介质的操作命令。 ATA 命令规范用于硬盘。 UFI命令规范是针对USB移动存储而制定的，实际上UFI命令格式是基于SFF-8070i和SCSI-2规范，总共定义了19个12字节长度的操作命令。

LemonSMS is a component developed in Java that provides a turnkey solution for application developers to incorporate into their Java applications the functionality of sending and processing of incoming SMS messages. LemonSMS acts as a middleware between a Java application and a GSM Modem or Data enabled phone. Because LemonSMS only provides an interface to the added SMS functionality, your application still handles access to data and business logic tier. With the easy-to-use LemonSMS API, developers can easily utilize SMS functionalities provided by LemonSMS.
