中文说明：art迭代程序一般于医学CT和一些超声波探伤的工程中，art算法作为反演程序，进行对目标稀疏方程的解，以及修正，随着一次次的迭代过程，使得反演结果更加趋近于真实的数值
English Description：
Art iterative program is generally used in medical CT and some ultrasonic flaw detection projects. Art algorithm, as an inversion program, solves and modifies the sparse equation of the target. With the iterative process, the inversion results are closer to the real value
