- 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 - Turning the grinding machine round , driven the barrel body to rotate by the transmission , the work piece that makes in the barrel , grinding stones and adding and grinding pharmaceutical and water in right amount , mix in barrel , is it is it flow layer to produce through action of gravity to make use of , flow friction on layer grind cutting , reach the work piece and process the surface quality taken
?转研磨机，是由传动带动桶身旋转，使桶内的工件、研磨石与添加适量研磨剂和水，在桶内混合，藉由重力作用而产生流动层，进而流动层的磨擦进行研磨切削，达到工件加工所要的表面品质。 - Then , the paper proposes process management of software development methods based on hierarchy model . it hierarchies process concept and classifies complex factors to different abstract layers : organization layer , work flow layer and material layer . according to different features , corresponding measures are applied to control and improve the software development process effectively
并在统一过程的基础上提出了基于层级模型的软件开发过程管理方法，将软件开发中的“过程”的概念层级化，将原来众多复杂的因素划分到不同的抽象层次：组织结构层、过程流层和物件流层。
