The amounts of relative changes in all features of kinetic tremor were contrasted among all tracking tests after learning the simple sinusoidal tracking. 动作震颤部份以均方根值代表振幅大小,进行功率频谱密度分析去探讨高峰频率于学习后之变化。
In the research on kinetic energy releasing of mine tremor due to falling-in, the influence to kinetic energy releasing of falling-in height, lithological characters and side collapse was quantitatively analyzed. 在采空区顶板冒落矿震动能释放的研究中,定量分析了冒高、岩性以及侧向塌陷对破坏动能的影响;
