Numerical results are obtained for velocity , temperature and concentration profiles , variations of both nusselt and sherwood numbers under different buoyancy ratio and inclination angles of = 15 - 90 . at a given inclination angle , heat and mass transfer rates decrease with heat and mass buoyancies and the buoyancy ratio b decrease from high positive values , and then increase again with the buoyancy radio b further decreasing after the velocity and transfer rates reaching a minimum 研究结果表明：倾斜角度一定，当热浮力与物质扩散浮力共存且二浮力之比b从较高正值变化到较高负值时，流体速度和热质传递速度从高逐渐变低并出现最小值，此后随着向下浮力的增大，流体向下流动且随| b |的增大而加速，热质传递速率随| b |的增大而重新增大。
Based on the analysis of thermal contact metamorphic aureoles , granitoid interior structure , quartz axis fabric and strain characters in the different rock unites of yuanshishan granitoid and its wall rocks , the emplacement mechanism of yanshishan granitoid was studied . the magmatic explictite dynamic was advanced in light of regional stress and magma dynamic research . those conclusion was synthesized to ascertain the emplacement mechanism - granitic magma ascended in dikes with the minimum critical width of the magma ascending channels about 2 . 213 . 88m and located in the core of yindianshan dome with the passive style of dyke explictite ; the later unite is a kind of multiple emplacement mechanism with the character of active emplacement of ballooning 同时运用岩浆动力学原理从另一个角度探讨其侵位驱动力。综上指出：经分凝后的活动性岩浆在深部侧向挤压和浮力的联合驱动下，沿深大断裂以最小临界宽度为2 . 213 . 88m的裂隙脉动上侵，整体以岩墙扩展的方式被动定位于银殿山穹窿的核部，但后期屋面前单元具有主动侵位的特点应为一种复合定位机制。
The calculated drafts covers the whole possible ship draft in the large amplitude motion ; secondly , the research creates and solves the ship large amplitude motion equations . on the one hand , the actual calculation takes into account the coupling between the different motion modes , on the other hand , in the process of calculation of the ship hydrodynamic coefficient , it considers the influence of the nonlinear factor . the hydrodynamic coefficient used in the calculation of froude - krylov force , diffraction force and radiation force changes instantaneously following the draft , and the hydrostatic buoyancy is computed very accurately for the instantaneous immerse hull 本文的研究分为二个部分：首先利用frank源汇法计算水动力系数，计算包括不同吃水时的附加质量和阻尼系数，吃水范围涵盖了船舶大幅度运动时所有可能的吃水；然后建立和求解船舶大幅度运动方程，在实际计算时一方面考虑了运动模态之间的耦合，另一方面在计算水动力时，考虑了非线性因素的影响。 froude - krylov力、辐射力、绕射力中的水动力系数随吃水瞬时变化，静浮力的计算精确到船体瞬时湿表面积，最后用四阶龙格?库塔方法在时域内求解船舶运动方程，并进行了载荷计算。
