检查更改过的文件备份，节省操作时间。 按Ctrl+Alt+F9弹出界面菜单。 显示备份状态和文件大小次数。 当目的地址是网络时，需要帐户和密码。 当正在备份时可以按停止键停止备份。 暂时只有增量备份 备份时间设定，格式可以是 00.00.00 或者 00:00:00。 进程优先算法选中后不影响其他程序工作(默认)。 点击确定保存设定开始计时。 自动启动并计时开始。-inspection changes to the document backup, saving hours of operation. Press Ctrl-Alt-F9 pop-up menu interface. Show backup status and the number of file size. When the destination address of the network, need to account and password. When the backup is at the stop button can stop by the backup. Incremental backup is only temporary backup sets the time, format or can be 00.00.00 00:00:00. Priority algorithm process after the elections does not affect other procedures (default). Click OK to preserve set the timer. Automatically activated and start time.

纯ALOHA协议 在该协议下，用户只要有帧产生，就会传送出去，发生冲突时，就等待一个随机时间后再重发。 所以对当前帧时，只有两种情况下可以发送成功： 1）当前帧时只有一帧要发送，且当前帧时的前一帧时无帧发送； 2）当前帧时只有一帧要发送（发送时刻为t），且前一帧时的最后一帧的发送时间不在（t- FRAMETIME）~ t这段时间内。 其他情况下都会产生冲突。 发生冲突时，错误帧继续传送，用户重新发送帧，设定一个随机数Rt，将该帧添加到第Rt/ FRAMETIME帧时上去，并设该帧的相对时间为Rt% FRAMETIME。这样即相当于用户等待一随机时间后重发。 对每一帧时进行上述控制，最终可得到成功发送的次数Suc，将其除以Suc = Suc /ARRAYLENGTH即得平均每帧时发送成功的帧数。 对于不同G，得到不同FrameArray，所得的Suc也不同，用一个数组来保存G与Suc的对应关系，再将其画出来。 -pure ALOHA agreement under the agreement, as long as users have a frame, it will transmit out, conflict, will wait for a random period of time before re-issued. Therefore, the current frame, there are only two circumstances can this success : 1) the current frame only one to send, and the current frame before one-time frame sent; 2) the current frame only to send a (t this moment), but before a final of a transmission time not (t-FRAMETIME) ~ t this time. Other cases will have conflict. Conflict, to continue to disseminate the wrong frame, users re-sending fram
