The electrical conductivity of Beijing dolomite and limestone has been studied by means of a high pressure apparatus of solid medium piston cylinder type. 利用固体介质活塞圆筒式高压容器测量白云岩与石灰岩的电导率。
Solid Lubricant Coated Piston 固体润滑性涂膜活塞
3D solid modeling of piston should be completed by UG software and design three kinds of runner and gate systems according to the actual production. 采用UG软件进行活塞的三维实体建模,并根据实际生产设计出三种浇注系统。
That is, the solid wall heat conduction in combustion chamber component of piston set-liner and lubrication and friction status of piston ring-liner influence each other. 也就是说,燃烧室部件活塞组气缸套的固壁导热与活塞环气缸套的润滑摩擦状况相互影响。
