- Many planets ( for example , ganymede , mercury , the earth , jupiter and saturn ) and stars ( for example , the sun ) possess intrinsic magnetic fields . the explanation for their existence and variation remains a great challenge to planetary scientists and astrophysicists . this article attempts to review some recent developments and difficulties in the study of magnetohydrodynamics for the electrically conducting fluid interiors of planets and stars . it is the fluid motions , usually driven by thermal convection , that generate and sustain magnetic fields through magnetohydrodynamic processes in planets and stars . in planets , the magnetohydrodynamic processes are strongly affected by the combined and inseparable effects of rotation , magnetic fields and spherical geometry . the key dynamics involves the interaction between the coriolis and lorentz forces . in the sun , it is the solar tachocline , a thin shear flow layer located at the base of the convection envelope , that plays an essential role in the solar magnetohydrodynamic processes which produce the 11 - year sunspot cycle . some results of a new nonlinear three - dimensional solar dynamo model are also presented
许多行星(如木卫三,水星,地球,木星和土星)和恒星(如太阳)具有内部磁场.对这些磁场的存在和变化的解释对行星科学家和天体物理学家是一个巨大的挑战.本文试图总结行星和恒星的导电流体内部磁流体力学研究的新近发展和困难.一般由热对流驱动的流动通过磁流体力学过程产生并维持在行星和恒星中的磁场.在行星中磁流体力学过程强烈地受到转动,磁场和球几何位型的综合影响.其动力学的关键方面涉及科里奥利力和洛伦兹力间的相互作用.在太阳中其流线,即处于对流层的薄的剪切流层在太阳的磁流体力学过程中扮演了一个基本的角色,并由之产生了11年的太阳黑子周期.本文也给出了一个新的非线性三维太阳发电机模型 - In order to predict hydrodynamic characteristics a computational system is developed including determination of the pressure distribution on a wing section by use of the conformal mapping method and panel method respectively and of the flow in boundary layer according to the thin shear layer approximation ( tsl ) for navier - stokes equation approach . the wing sections of naca4412 and naca0012 are applied to test the computational system . the numerical inspection shows that the panel method with better precision and the momentum and the displacement thickness of boundary layer can be used to complete this calculation
本文分别用守屋的保角变换法和基于源汇涡分布的面元法，建立了计算桨叶表面压力分布的数学模型；应用纳维-斯托克方程的薄层近似理论模式和有限差分数值方法，建立了计算机翼表面边界层内部流动的数学模型；应用桨叶表面边界层内部粘性流动和外部势流流动在边界上的匹配算法，建立了桨叶表面二相流流动的计算方法和相应的计算机程序。 - These clearly demonstrate that the mcc formatted by long - history processes with poly stages . by strain analysis , the fabrics deformational style of the yagan mcc are mainly shearing type , the yagan mcc is mainly a thinning shear zone with volume loss , which varies from - 31 % ~ - 58 % . analysis of kinematic vorticity ( wk varies from 0 . 453 - 0 . 809 ) shows shear type of the shear zone is neither pure shear nor simple shear but general shear
应变分析表明，亚干变质核杂岩主期变形为以剪切变形为主(罗德系数u在0 . 08 ? 0 . 32间)压扁次之( u0 . 89 )的变形类型，核杂岩区为一有体积损失的减薄型剪切带，体积损失率达- 31 ? - 58 。 - This paper analyzes and designs the big - space rc thin shear wall residential structure , ! ! includes designs and analysis for shear walls by method of material mechanics and related software , columns , it is designed and analyzed for beams and slabs by theory of elastic and method of moment index , but it is principal for beams and slabs to compute deformation and crack . at last it is compared with three structrual types , although the cast of new structrual types is higher than marnoey structre . it has some merits . lt gives the theory base for design of resident
