查询词典 diffract

In the course of the impulse through underground mediator, because the physical property and the geometric property of mediator is non-uniform, wave form and wave amplitude will change very much and the impulse after shock、antenna direction figure、the couple degree of ground surface、system interfere、non-uniform of the underground mediator、reflection surface's rough cause the disturb of radiation scatter and diffract will complex the figure .

脉冲在通过地下介质的过程中，由于介质的物性和几何性质的不均一性，波形和波幅将发生较大的变化，而脉冲余振、天线方向图形、天线的地表偶合程度、系统内部的干扰、地下介质的不均匀、反射面不光滑等引起的辐射效率、散射的变化以及剖面旁侧的绕射等干扰，均使实时记录图像复杂化。
