双重迭代法 meaning in Chinese

double iteration procedure

In some high degree exploration areas , the initial macro interval velocity model is firstly established by using the logging - constrained method , and then , the double - iteration method in multi - domains is applied on velocity model updating to meet the accuracy of prestack imaging
在地震勘探程度较高的地区，首先采用测井约束法建立初始宏观层速度模型，然后利用多域双重迭代法进行优化更新，以达到满足叠前成像精度要求的目的。
