本文应用模糊数学方法,首先对地质结构(凹陷、凸起)进行判别,然后运用人工整理速度谱的经验法则,把速度曲线的各个备择点看成一个四维空间的模糊点(模糊集),综合进行评判,定出各个模糊点的亮度,并据已择点的连线,完成速度谱的自动整理。本方法能够简捷、灵活、极其近似地模拟人二整理速度谱的过程。利用此法编制的地震速度谱自动整理程序,在泰曼普计算机上已经获得了令人满意的水平叠加剖面。
In this paper, the fuzzy mathematics method is applied to distinguish the geological structure (depression and bulge) firstly. Then, by using the rule of artificially arranging the velocity spectrum, each alternative point of the velocity curve is considered as a fuzzy point (fuzzy set) in four- Comprehensive evaluation, set out the brightness of each fuzzy point, and according to the connection point has been selected to complete the automatic speed spectrum. The method can be used to simulate the process of finishing the velocity spectrum in a simple, flexible and extremely approximate way. Seismic velocity spectrum automatic finishing program prepared by this method has obtained a satisfactory horizontal superimposed profile on the Temanprat computer.
