说明：  用qt3实现的Wake On Lan也就是远程唤醒（远程开机），即通过一台PC向另一台已经关机但仍连接电源PC发送网络数据包，使其开机的功能，前提是两台PC同处一个局域网内，且被唤醒方的网卡支持网络唤醒功能（现在网卡基本上都支持啦）
(Qt3 realize with the Wake On Lan is a remote wake-up (remote boot), or through a PC to another has been turned off but still connected Power PC to send network packets to boot function PC with the premise that two within a LAN, and wake up to the card features support for Wake on LAN (NIC now basically support you))
