由分析得到,对于确定的光源光谱宽度,波导端面反射率只有取合适的值,才能取得最灵敏的调制效果。
By analysis it is shown that the maximal modulation sensitivity comes from an appropriate end reflection coefficients of OWFPM for a certain light source spectrum width.
该方法以计数器法测取脉冲的主体宽度,用时间-电压转换法测取脉冲的零头时间,并以此作为量化误差的校正值。
In this method the main part of the pulse width is measured by counter, and the odd of the pulse width is measured by time-voltage conversion method.
集中力作用处剪力滞效应与其它截面相比明显增大,我国现行桥规(JTJ023-85)中关于有效宽度取全桥等宽的说法需要进一步研究。
The shear lag effect of the section under concentrated load is more remarkable than that of other sections. National Standard (JTJ023-85) is worth discussing further.
