Results of the experimental groups: Comparison with the control groups, in 6h and 8h groups eminences of ependymal cells with cobblestone-like appearance were seen, their microvilli were further richer, and a number of microholes could be found on their base. In body part of SFO cell membrane of some ependymal cells were broken completely, their cytoplasm was no longer seen, and cell nucleus located at one side of the cell, 5-7μm in diameter and dividing lobe-like in shape. Beside those cells some ependymal cells appeared many folds on the top of surface. In 2h and 16h groups the observation results seemed no significant differences from the corresponding control groups.

The simulation results shows that when the hydroforming for real axle housing needs two bulge processes and the specific value of the two bulge ratio is about 1, the result is the best one; To obtain an appropriate route of loading force need adjust internal pressure and axial compression force for many times and according to the failure, the size of the two forces which has been mentioned can be rapidly and rationally adjusted; Because of good greasing conditions influencing largely, reducing the friction between tube blank and die inside surface as well as possibly not only makes more materials flow into the bulge area but effectively diminishes the axial compression force; The good or bad characteristics of tube blank material is also one of the decisive factors and when material is selected, we first consider its' formability.

模拟结果表明，当后桥壳需要两次进行胀形，两次胀形比比值约等于1时，胀形结果最好；合适的加载路径要经过多次调试，能根据胀形缺陷对内压力和轴向力的大小进行迅速地合理调整；良好的润滑环境对后桥壳液压胀形的影响巨大，要尽量减小管坯与模腔内壁的摩擦力，不但使更多的材料流入胀形区，而且能有效的降低轴向力的大小；管坯材料性能的好坏也是影响胀形的决定性因素，选材时首先要考虑材料的成形性。

Some cell dropped into the cavity and became free. Thrombosis or part organization could be seen. The internal elastic layer became thin, disappear or broken. In internal and middle layer existed fibroblasts, fibrocytes and collagen. Some of the wall indicated hyaline change, soomth muscle cell decreased greatly. The massive inflammatory cells invaded the middle and external layer. There were many foam cells in the capsule tissue. Cytoplasm was filled with fatty tissue and cholesterol. some cavities were full of thrombosis. Some thrombosis was fibrosis, the bottom was organization. The surface of the thrombosis existed red blood cell and librae.(2)Elatic fibrila staining: the internal elastic menbrane almost completely disappeared, the intact internal elastic menbran could be seen in the new small vessels.

幸运的是醒来后的犯人并未追究管明强的责任，痛定思痛之后反而感谢他，让他得到了理应该有的惩罚，两人再次见面时都互相表示着抱歉，愿意承担所有的结果，这多少消除了管明强在单位的负面影响，留守观察的期间孟灿一直陪在他身边，和她说自己女儿成长的经历，易夕看问题处理差不多了，见孟灿还没有要回恩宇的打算，便问她可否让李子星带杨晓月过来看看，以好在她童年的印迹里保存一些特别的情景，寒假刚刚来临，听说李子星叔叔要带自己见妈妈，杨晓月异常兴奋，大包小包收拾一大堆东西，好似春节也不回家过的般，杨启行得知孟灿此行异常顺利，希望她趁外出的机会好好休息休息，如果将杨晓月叫身边，也不要太操心太累，得知是易夕的主意，加上还有李子星护航，便没有多说别的话，择日清晨送两人去了车站，因赶时间上班，没多留点时间就道别去了单位。
