The earth is a complicated system, and it has been continuously moving differentiating and evolving since it had been formed. Not only has the earth layering structure, but it has vertical movement of materials. The movement is prompted by the mechanism of force and heat of the centrifugal force to be formed by the rotation and revolution of the earth, and difference of temperature, pressure, density, viscosity and velocity in the between core and mantle, and radioactive heat, et al. The expressive means of the mechanism of force and heat are the precesses of mantle plume and mantle fluid. Not only are ore-materials of core and mantle carried directly into crust, but ore-materials of crust are activated and accumulated into proper location by the mantle fluid having the supercritical nature.

地球是一个复杂的系统，自形成以来，一直处于不停地运动、分异和演化过程；它不仅存在着圈层结构，而且伴随其自转和公转的离心力，以及核幔间的温度差、压力差、密度差、粘度差、速度差和放射性蜕变热等动热机制，同时存在着以地幔柱和地幔流体作用方式的物质垂向运动；这一过程，不仅直接向地壳带入核幔成矿物质，而且通过流体自身的超临界性质，将沿途活化已有初步富集的成矿物质转移至地壳适宜部位集中成矿。

In this thesis, the influence of column force, joint hoop reinforcement, and repeat load on the stress and sheer bearing capability of inclined pressure bar is analyzed utilizing finite element software. In the case study, the column axial force's influence on the inclined pressure bar's equivalent width, stress and sheer bearing capability of RCFEN is obtained by changing the column force when modeling the RCFEN with ANSYS. In the former model, the joint hoop reinforcement influence on the equivalent width inclined pressure bar and the strength of RCFEN is achieved by changing the quantity of joint hoop reinforcement; the inclined pressure bar's equivalent width and the strength variation of RCFEN under cyclic load are gained by applying low frequency cyclic load on the inflection point of column and the middle of beam.

First, the angular velocity function and maneuver load for certain maneuver flight (including hover, dive-hike and these two combined) are set up. The simulation results of the vibration of double-disk rotor system with cantilever supported on rigid bearings show that rotor would be apparently deformed under maneuver load. Second, the performance of oil force of SFD in maneuver flight is analyzed. The results show that in maneuver flight, the SFD with centering spring will become eccentric and its oil force will be time-related and offset-related. Then, SFDs are introduced into typical Jeffcott rotor system. The whole system will be statically displaced in maneuver flight and the nonsynchronous components of oil force appear in the response of rotor system.
