摘　　要：为方便地震勘探技术人员优化三维观测系统设计方案,针对野外采集的数据,通过对叠加特性曲线方程的分析,建立影响系统设计参数评价模型。模型核心部分是特征点模块,计算出特性曲线方程特征点、极值及有效波的被压制量∫。软件编程采用循环语句及冒泡排序法,最终结果是输出模块输出压制带的宽度△a、压缩量△P、有效波的被压制量∫。在计算机上模拟特定的观测系统,对多次叠加之后的效果进行预测和评价,有利于选择和设计出最佳方案的三维观测系统。软件具有操作简便、实用性强等特点,适合野外操作人员掌握和使用。To optimize three dimensional observation system design scheme for the seismic exploration technology personnel,in view of the field acquisition of data,through analysis of the overlay characteristic curve equation,the evaluation model of influencing system de- sign parameter is established. The core part of model is feature point module, calculate the characteristic curve equation feature point, ex- tremum and pressing quantity f of effective wave. Software programming uses cyclic statement and bubble sort method,the final result is the output module outputs suppression band width Aa,deflection AP,pressing quantity f of effective wave. Simulate specific observation system on the computer, the effect after multiple stacking is predicted and evaluated, which is beneficial to choose and design the best so- lution of three dimensional observation system. Software has simple operation, strong practicability etc, can be suitable for field operation staff to grasp and use.
