PCG2 (Preconditioned Conjugate-Gradient Method 2), the most popular mothod used in groundwater field, was used to solve the distributed model of large-scale groundwater system. Its principle and effect was analyzed mathematically, and verified by some specifi cexamples. Numerical results acquired by PCG2 are accurate, it demonstrates that PCG2 is effective on methodology itself and man-ralated operation. So PCG2 is worthy of popularizing in the area of groundwater system for numerical analysis.

在“以嫁为赢”的社会主流价值观里，相信这个标题吸引了很多人的眼睛。当很多女青年还睁着花痴眼恨嫁时，当一众怨妇聚在一起叽叽喳喳痛陈心塞婚史时，当某些家庭主妇谨小慎微地以夫为荣时，当大批晒娃狂魔开启以孩子为生命主题的姆妈模式时，另类的三种女人正气定神闲地在人群里飘然而过，美好得像一幅画。她们分别是剩女、离异女和女汉子——当然说的是这三类人中保有自我，没有在社会舆论中迷失的女人。她们中的一些人在经历了大
