This paper, for the first time, uses "The Hypothesis of Global Spiral Tectonic "to study geotec-tonic of certain regions, analyses theoretically the stress distribution of mantle's spiral convecting action in lithological spiral tectonic elements and puts forward different directions and features of China continent. It seems that complex faults and rift structures can be unified and explained by spiral centripetal movement of the spiral tectonic elements in East Asia. The intense faults and rift deformations...

This paper, for the first time, uses "The Hypothesis of Global Spiral Tectonic "to study geotec-tonic of certain regions, analyses theoretically the stress distribution of mantle's spiral convecting action in lithological spiral tectonic elements and puts forward different directions and features of China continent. It seems that complex faults and rift structures can be unified and explained by spiral centripetal movement of the spiral tectonic elements in East Asia. The intense faults and rift deformations on large scale, composition forms and different deformation results in Guizhou comprehensively show typical regional tectonic features of spiral tectonic elements. According to these features, the paper deals with the theoretical and practical significance of "The Hypothesis of Global Spiral Tectonic" in geotectonic research, ore-forming prediction and seismic prediction.

本文首次将“全球旋涡大地构造假说”用于具体地区的地质构造研究。从理论上分析了地幔旋涡对流作用在岩石圈旋涡构造单元内的应力分布。提出中国大陆的不同方向、不同性质、看似繁复的褶皱断裂构造,均可用东亚旋涡构造单元的旋转向心运动得到统一、合理的解释。贵州境内大规模的强烈褶皱和断裂变形以及多种形象的构造组合形式和不同的变形结果,综合地表现出了旋涡构造单元的典型区域构造特征。结合贵州特征初步探讨了“全球旋涡大地构造假说”在大地构造研究、成矿预测、地震预报等方面的理论与实际意义。

The time integration with explicit partitions varying time step for large displacement, small strain problems is presented.For purpose of treating arbitrarily large rotations,node orientations are described by unit vectors and deformal elements are treated by a co—rota- tional(rigid—convected)description.Energy balance calculations are provided to check nu- merical stability.The numerical results show that the program is quite versatile in treating complex engineering structures.

The deformation of spindle unit of machine tool affects processing accuracy of the spindle. When spindle is rotating in high speed, acting result of centrifugal force and gyro moment of rolling elements makes the support status of spindle changed, the deformation character istics of spindle is different from that at the static status. The relation between spindle deformation and load in high speed rotation status, the relation between load and deformation of support bearing are established by finite differential method. Non-linear equation group of load and deformation of the spindle unit has been solved by Newton-Lfeison's method, the effect of rotating speed on spindle unit has been analyzed.
