用法和例句

By calculating the arrival time difference of the disperse signal aroused by damage using active lamb wave and wavelet transform,damage position can be detected according to ellipse localization method.

采用主动Lamb波和小波变换计算损伤散射信号的时间延迟,根据椭圆定位法进行损伤定位;提出压电传感器星形布置的优化布置方法,结合多路扫查,解决椭圆定位法的损伤监测盲区,从而扩大损伤监测范围、提高损伤判别的准确性,并能进行损伤程度的判别。

The circular integrodifferential operators[1,2] of John Daugman is robust and accurate.

Daugman提出的圆周差分定位法鲁棒性和精确性较好,但当在整幅图像中搜索虹膜时,将非常的耗时,同时也会因为受到睫毛等的干扰而降低定位的精确性。

On the basis of time reversal focus theory and four-point arcs location method,and the improvement and extendibility to four-point arcs Location method,an imaging representation using time reversal theory was proposed for damage location and identification.

针对结构损伤监测及表征方法研究的不足,分析了时间反转聚焦和四点圆弧定位法原理,在此基础上对四点圆弧定位实现方法进行了改进和扩展,提出了基于时间反转方法的结构损伤图像表征方法,采用Lamb波主动健康监测技术在铝板结构试件上进行了实验验证研究。
