It maps original data to kernel space to get a kernel matrix, and utilizes kernel function and L1 norm to minimize the distance function.

运用核函数将原始数据映射到核空间中得到核矩阵，再利用L1范数使距离函数达到最小。

Tensile strength was found to decline with increase of the ratio of average chord lengths of the two phases (L1/L2) and mass center distance (D).

结果表明，当分散相一定时，拉伸强度随两相相对尺寸的增大和分散相颗粒相关性的减弱而减小。
