The author has made a detailed analysis of the satellite gravity data over Wenchuan, Motuo, Zhongba, Jiashi and Taiwan Areas in China, where earthquakes more than magnitude of 6 took place in recent several decades. It is surprising that the gravity field patterns over these areas are extremely similar, which is characterized by the following features:(1)Paired positive and negative anomaly.(2)Epicenters usually were located between the pairs where the gradient of gravity field was the steepest.(3)The value of positive peak increased and its width decreased at higher order field.(4)The distance between positive and negative peaks varies in different tectonic background.(5)Different styles of crustmantle material diapirism in different stress fields. Geologically, rheological diapirism of high density crustmantle material could be a reasonable explanation to this unique pattern.

笔者详细分析了中国汶川、墨脱、仲巴、伽师和台湾等地的卫星重力资料(这些地区在近几十年来均发生过6级以上的大地震)，惊奇地发现，在这些地区，卫星重力场的样式具有极大的相似性，它们表现在：(1)卫星重力场的正负异常值成对出现；(2)震中通常位于重力场峰值间的陡梯度带；(3)由低阶到高阶的重力场正异常的峰值增大而宽度变窄；(4)正、负峰值间的距离随所处的大地构造背景而变；(5)不同应力场壳幔物质底辟的样式不同，从地质上看，高密度壳幔物质的流变底辟作用，可以合理地解释这种独特的样式变化。

This type of pump shell is the level of the axis through the surface of separate subdivision, the removal of the shell with the inhalation pump, exhaust pipe has nothing to do maintenance more convenient.

The results indicated that four SOD bands were identified in five tissues, and the band with the biggest mobility ratio were found weakly in gill, digestive gland and adductor muscle but not in foot and mantle. Two ATPase bands were found in four tissues except digestive gland. One MDH band was found in five tissues, but the MDH gene expressed strongly in foot and adductor muscle. Two ME bands were examined in foot, adductor muscle and mantle, but the band with smaller mobility ratio was found in gill and digestive gland.

结果表明，SOD在紫贻贝的5种组织中均有表达，共有4条酶带，但迁移率最大的酶带在足和外套膜中未出现，而在另外3种组织中呈弱表达；ATPase在除消化腺外的组织中都表现为2条带；MDH在5种组织中都表达出1条酶带，其中足和闭壳肌的MDH染色最深；ME存在1~2条酶带，其中迁移率大的条带在5种组织中都有表达，而迁移率小的条带只存在于外套膜、闭壳肌和足中。

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。
