Resorting to the Roberts-Chebyshev theorem,we replace the two cranks of a crank-rocker cognate mechanism with a double bar,which is required to satisfy certain geometrical and motion conditions,and we change the mechanism thus reformed into a geared five-bar mechanism so that one of its links can fully rotate with the link connected with it.

借助于Roberts-Chebyshev定理，将曲柄摇杆轨迹同源机构的两曲柄分别用一双杆组代替，并要求双杆组满足一定的几何尺寸条件和运动条件，使变形后的机构为齿轮五杆机构，且满足机构的一个连架杆以及与其相连的连杆能够整周转动。

An ultrashort pulsed-laser beam is composed of a series of monochromatic continuous waves. According to Parseval theorem, the time-averaged intensity can be calculated by the sum of the intensity of these monochromatic continuous waves. Then we derive an equation to study Talbot effect of a grating illuminated by an ultrashort pulsed-laser beam.

我们采用了频谱分析法，即把超短脉冲光波看成是由一系列的单色光波组成，根据Parseval定理，光栅Fresnel衍射的平均光强由一系列的单色光波的衍射光强之和而求得，这样我们给出了一种分析光栅在超短脉冲光波照射下泰伯效应特性的方法。
