在脉冲波状态下的組合法中,輸出端干扰波的强度、反映强度变化的包絡形状与輸入波形、相应的包絡、持續时間及干涉系統参数等等之間的关系如何;各种脉冲波方向特性曲綫(峯值法、能量法及本文的面积法等)各有何特点,何者較适用而簡便等这一方面的問題,在有关組合法的文献中仍然缺乏論述。本文将通过对組合法地震記录上干扰带、干扰波包絡的暫态变化規律的分析,以及对不同脉冲波方向特性曲线的比較,提出这些問題的解答。
In the combined method of pulse wave state, the intensity of the interference wave at the output end, how the relationship between the envelope shape reflecting the intensity change and the input waveform, the corresponding envelope, the duration and the parameters of the interference system, etc .; various pulse waves The characteristics of the direction characteristic curves (peak method, energy method and the area method of this paper), what are the characteristics of each, which are more applicable and more convenient, are still lacking in the literature about the combination method. In this paper, we will present the solutions of these problems through the analysis of the transient variation of the interference band and the interference envelope in the combined seismic record and the comparison of the characteristic curves of different pulse waves.
