reversal point method

基本解释

Reversal point method which is adopted by gyroscope to seek north at present reduces the speed of north-seeking and is hard to make the instrument automatic.
目前陀螺初寻北大多还是采用逆转点法，影响寻北速度且难以实现仪器自动化。
Based on the focalization ability of time reversal theory to the wave origin , the wave propagation was rebuilt by an image method which displays the damage as the focusing point .
利用时间反转法对波源的自适应聚焦能力，重建信号传播波动图，通过信号聚焦显示损伤位置和区域。
The input errors of BP(Back-Propagation) network are classified into dead point error and phase reversal error in this paper. A highly reliable reconstruction method for a BP network is proposed.
本文将BP网络的输入错误分为死区错误和反相错误，提出了对输入容错的高可靠的BP网络的构造方法。
