1·The difference between the measurements is independent of a constant determinate error.

测量之间的差异与恒定测定误差无关。

2·Base on the equation established, an accurate method is used to determinate the allowable error angles which can make the mechanism realize self adjustment presented.

在建立的自调位移方程基础上，提出了一种确定机构能够实现自调的允许误差角的精确方法。

3·Meanwhile, the communication system analysis based on determinate channel model demonstrates that the robustness against the channel estimate error is evidently enhanced.

同时，基于确定信道模型的通信系统分析显示，该方案的抗信道估计误差的鲁棒性明显提高。
