The onset latency, N-wave latency, P-wave peak-to-peak amplitude and area of SSR were measured respectively. 分别测量SSR各波潜伏期(起始、N波、P波)以及峰-峰波幅和面积。
The average speed of SAW motor of 20 mm/ S is measured under a diving voltage of 80 V ( the peak-to-peak amplitude) by the method of measuring the speed with a digital camera. 以数字摄像测速技术测得驱动电压峰峰值为80V时,表面弹性波马达平均速度约为20mm/s。
The result shows that the optical field peak intensity increases gradually, the peak-to-peak amplitude becomes shorter, the beam width becomes narrower, and the modulation factor becomes bigger as the nonlinear effects enhance. 结果表明:随着非线性效应的增强,光场峰值强度逐渐增大,峰值距离逐渐缩短,光束束宽不断减小而调制因子逐渐增大。
When concrete prisms are compressed axially, the peak-to-peak amplitude of P wave and Rayleigh wave both decrease with increasing stress. After unloading, waveforms can not recover to their initial states, and the velocity decreases slightly. 混凝土柱在轴向加载情况下,Rayleigh波和纵波峰峰值均随应力增加而减小,并且卸载后波形不能回复,波速略有减小。
The voltage peak-to-peak value is 10.24V with amplitude resolution 0.01V. The phase range is 1 to 360 with phase resolution 1. 输出电压峰峰值为10.24V,调幅步进为0.01V;初相调节范围为1°~360°,初相调节步进为1°。
