Standard test method for rubber property - measurement of the viscous and elastic behavior of unvulcanized raw rubbers and rubber compounds by compression between parallel plates 通过平行板之间压力测定橡胶化合物和非含硫生橡胶黏性和弹性的橡胶特性的标准试验方法
The flow between two gaps in the new type of axial trust balancing device was assumed as laminar move , and the flowing physical model in these two gaps was simplified into laminar move in the gaps between two parallel plates 摘要将新型轴向力平衡装置两个间隙中的流动假设为层流,并将两个间隙流动的物理模型简化为平行板间隙的层流运动,推导出了径向间隙与?漏量关系式和考虑离心力效应时轴向间隙与?漏量的关系式。
The cubic law which describe the law of fluid flow in fracture is based on parallel plate joint model , in this paper the cubic law is modified and non - parallel wedge - shaped joint fluid flow equation is formed , coupling relation between seepage and stress is given based on permeability and joint distortion as the linkage between two field , while the coupling mechanism is simple and explicit 描述裂隙水流运动规律的立方定律是建立在平行板裂隙模型基础上得出的,本文对立方定律进行了修正,推导了非平行楔形裂隙水流方程,根据渗透性和裂隙面变形关系给出了单裂隙渗流与应力耦合公式,耦合的机理十分简单、明确。
A coaxial micro - pulsed plasma thruster ( micro - ppt ) improved from the standard pulsed plasma thruster ( ppt ) is drawing attention by its advanced properties of low volume , high isp , high efficiency and stabilization . a coaxial micro - ppt using solid inert propellant teflon has been made in center for space science and applied research ( cssar ) , chinese academy of sciences 针对应用于微小卫星的电推进技术,各国争相开展相关的研究,其中一种经由传统的平行板电极ppt改进的同轴型脉冲等离子体微推进器(以下简称同轴型微ppt )由于其尺寸小、比冲高、效率高、工作可靠等特点尤其受到关注。
