When tuning this value, note that the optimal transmissionwindow is related to the bandwidth and the latency in a straight-forward way.
当调整这个值时，请注意频宽和延迟时间与最佳传输视窗有直接的关联。
2
After using this transmissionwindow, can reduce the clean room to open the door effectively the number of times, reduces the threshold the clean room pollution degree.
使用该传递窗后，能有效地减少洁净室的开门次数，把洁净室的污染程度减少到最低限度。
3
The optimal backoff window size and contention window size are given, and the transmission efficiency is calculated by analyzing the collision probability of contention request.
