5.12 Wenchuan 地震的基因机制仍然正在被辩论，仍然对大多数现象没有有说服力的一般解释。这是因为研究人员们在 seismogenic 过程忽略了 Minshan 块的重要角色。在场的作者一条新意见基于地质的调查和全面分析。Minshan 块是在西北三角的地震出现的一个关键构造元素四川的有缺点的块省。Minshan 块被 Longmen 山脉破裂在西方在南方，在东方的 Huya 破裂，在北方的 Tazang 破裂和 Mounigou 山谷破裂毗邻。块的刚硬比邻近的区域的那些相对大。当它突然与瓶颈效果在东方三角结束附近逐渐变细时，东方运动由地区性的最大的主要 geo 压力推了的块被限制，并且这在它附近引起 geo 压力集中。块的形状像棺材、在上面的部分宽、在更低的部分狭窄。当强烈地震沿着块边缘发生时，固定资本效果暂时释放了，导致传给 Pingwu-Qingchuan (Motianling 块) 的 geo 压力区域。这传播引起了 Wenchuan 地震余震在 Qingchuan 区域被专注。当块移动了东方，块的背，即 Mounigou 山谷骨折的南方片断，在 Wenchuan 地震以后变得活跃。因此，余震沿着 Mounigou 山谷骨折的南方片断被集中。因为南方边缘由前面范围破裂组成， geo 压力逐渐地释放了，引起沿着 Guanxian-Anxian 破裂的许多余震。在 Wenchuan 地震以后做的地质的调查表明在 Minshan 块的南方边缘的表面破裂沿着前面范围破裂也不沿着 Beichuan-Yingxiu 破裂(中央破裂) 发生。在到几公里和它的从几米的南方边缘范围的表面破裂的长度在军队飞机是分布式的在里面(空间得仔细，平行或 subparallel，像步的表面破裂) 。垂直、水平的排水量到处变化并且推进的部件在 Longmen 的中间的片断是主导的山脉结构带。不过，罢工表面破裂滑倒在 Longmen 的北方片断是主导的山脉结构带。因此南方边缘是原来的地震结构。Minshan 块的南方边缘的突然的推?

英文摘要：

The genetic mechanism of the 5.12 Wenchuan Earthquake is still being debated and there is still no convincing general explanation for most of the phenomena. This is because researchers have ignored the important role of the Minshan block in the seismogenic process. The authors present a new opinion based on geological survey and comprehensive analyses. The Minshan block is a key tectonic element of the earthquake occurrence in the northwest triangle faulty block of Sichuan Province. The Minshan block is bordered by Longmen Mountain Range fractures in the south, the Huya fracture in the east, the Tazang fracture in the north and the Mounigou Valley fracture in the west. The rigidity of the block is relatively larger than those of the adjacent regions. The block＇s eastward movement pushed by regional maximum main geo-stress is limited when it suddenly tapers off near the east triangle end with a bottle-neck effect, and this causes geo-stress concentration around it. The shape of the block is coffin-like, wide in the upper part and narrow in the lower part. When a strong earthquake occurs along the block margins, the lock-up effect temporarily released, resulting in geo-stress transmitted to the Pingwu-Qingchuan （Motianling block） region. This transmission caused the Wenchuan earthquake＇s aftershocks to be concentrated in Qingchuan region. As the block moved eastward, the back of the block, i.e. the south segment of Mounigou Valley fracture, became active after the Wenchuan Earthquake. Therefore the aftershocks were concentrated along the south segment of Mounigou Valley fracture. Because the south margin is composed of the front range fracture, the geo-stress gradually released, causing many aftershocks along the Guanxian-Anxian fracture. The geological survey made after the Wenchuan Earthquake reveals that the surface ruptures in the south margin of Minshan block occur not along the Beichuan-Yingxiu fracture （central fracture） also along the front range fracture. The length of the surface rupture in th
