Analyzing the relation between earthquake and structure distortion, main fault belt, crust, upper mantle, ground fracture, hotspring, geotherm, conductance frame, stress state in Guanzhong area is analyzed with earthquake mechanism, isoseismal line, crustal stress measure, fault displacement measure, and simulating test results. Earthquake formation mechanism is discussed with dynamics mechanism in Guanzhong base. There are 3 forces and a good medium environment, which are main reasons caused earthquake happened in Guanzhong area. The first force is NE and NEE level extrusion one which is parallel with long axis of Guanzhong base. The second one is level strain which is vertical with long axis of the base.

对地震与构造形变、主要断裂带、地壳及上地幔、地裂缝、温泉和地热、电性结构等关系进行了分析研究，通过震源机制解、地震等烈度线、地应力测量、断层位移测量及模拟试验等成果，分析了关中地区的地应力状态，从关中盆地的动力学机制，对该区的地震成因机制进行了探讨，认为与关中盆地长轴平行的NE和NEE向的水平挤压力、与盆地长轴方向垂直的水平张力及地幔上涌力三组力的作用，加之壳内高导层这一有利的介质环境，是导致关中地区地震发生的主要原因。

Axis hook acting in concert with compensation has been adopted, and the hook points to catch thread loop at equivalence to left and right,there by reducing skip stitching and thread breakage considerably.

采用了梭轴配合补偿机构，旋梭在勾线时的左右位置均等，可防止跳线以及断线。

The distuibution of axial plane stubs and stub crossing points are non-uniform and quantity of them is not equal when the blade is made by using traditional design method of turbine. These are not benefit with calculating wood model and drawing. In this paper, to make blade wooden patterns is using blade mean camberline. This makes the wooden patterns meet the demand of the design and meet the shape of the runner blade. And this can agree with requirements of hydro and mechanical analysis and making the model of blade by using the numerical control machine. It has reference value to whole design of turbine.

针对传统方法设计水轮机叶片时，获得的轴面截线和截线交点疏密不均、个数不等、不利于叶片木模的计算和绘形的缺点，文中利用叶片叶型骨线数值生成叶片木模图，使新的木模图能够更好的体现设计要求和符合实际转轮叶片的形状，并能满足进一步的水力和机械分析以及数控机床制作模型叶片的需要，对水轮机的整体设计具有参考价值。
