microsoft crm3.0 实施指南 本指南是为负责 Microsoft CRM 实施的团队编写的，提供了实施中每个阶段所需的信息和 工具。在小规模的组织中，一个人可能会承担几个角色。但在较大的组织中，可能每个角色由几个人来分担。-microsoft crm3.0 Implementation Guide This guide is responsible for the implementation of Microsoft CRM team prepared to provide at each stage of the implementation of the necessary information and tools. In small-scale organizations, a person may assume several roles. However, in larger organizations, each role may be shared by several people.

This circuit automatically turns on a night lamp when bedroom light is switched off. The lamp remains ‘on’ until the light sensor senses daylight in the morning. A super-bright white LED is used as the night lamp. It gives bright and cool light in the room. When the sensor detects the daylight in the morning, a melodious morning alarm sounds. The

单端反激式开关电源具有结构简单、输入输出电气隔离、电压升／降范围宽、易于多路输出、可靠性高、造价低等优点，广泛应用于小功率场合。然而，由于漏感影响，反激变换器功率开关管关断时将引起电压尖峰，必须用钳位电路加以抑制。由于RCD钳位电路比有源钳位电路更简洁且易实现，因而在小功率变换场合RCD钳位更有实用价值。 -Single-ended flyback switching power supply with a simple structure, input and output electrical isolation, voltage up/down range, easy to multi-output, high reliability and low cost, widely used in low-power occasions. However, due to leakage effects flyback converter power switch off when the voltage spike caused by the need to be inhibited by clamping circuit. RCD clamp circuit as a result of active-clamp circuit than the more concise and easy to realize, and in low-power transform RCD clamp occasions more practical value.

利用通讯模块进行数据通信，就是将数据体作为短消息的内容，从发送方的通讯模块发送出去，通过短消息中心进行转发，接收方通讯模块收到此短消息后即存储在SIM卡上，模块外接的控制器（如单片机、计算机等）从模块中读取短消息后，根据需要将无用的信息去除，取出有效信息，然后将SIM卡中的短消息删除，这样就完成一次单向数据的传输。利用通讯模块的短消息方式实现数据的发送和接收具有通信成本低、系统容量大、抗干扰能力强等优点，而且短消息经过服务中心再到达目的地的特点使通讯模块无需24小时开机，降低了系统功耗，特别适合遥控、遥测、远程信息处理和通信等领域。-GSM
