类型和特征说到这里,我们初步搞清了次生干扰的一些基本特征。现在对此做一总结,并以一些图来说明。次生干扰的形成和分类图19A是次生干扰形成的原理图,我们用几个弹簧来说明次生激发的原理。当大地的弹簧振动时,地上的那个弹簧会带着那个小重块作上下振动甚至左右摆动。图19B是 Type and Features Here, we have initially figured out some of the basic characteristics of secondary interference. Now a summary of this, and some figures to illustrate. Formation and Classification of Secondary Disturbances Figure 19A is a schematic diagram of secondary interference formation. We use several springs to illustrate the principle of secondary excitation. When the earth’s spring vibrates, the spring on the ground will vibrate up or down with that small weight or even swing left and right. Figure 19B is
