英文摘要：

The complexity of higher order correlation function increases exponentially with the growth of the dimension.An improved high-order correlation function calculation method is presented in this paper.A new pruning research algorithm based on the KDC-tree data structure is designed.The implementation of three points correlation function is given,and it is accelerated with parallel technology to optimize the calculation of high-order correlation function.Experimental results validate the correctness and efficiency of this method.
