It mainly analyzed the morphological characteristics of pores and resin canal on transverse section and wood ray on tangential section on the basis of wood structure. 结合木材组织构造总体特点,本文重点分析了横切面上管孔、树脂道,弦切面上木射线形态特征。
The vortices that are formed on the tangential section, there existed mass transfer between inner and outer parts of fluid. 环隙切剖面上形成的涡,其内部流体都要与涡外部的流体进行质量交换。
Flow Field Test on the Tangential Section(TS) of Polypropylene Tubular Membrane Module Annular Gap in Rotating Linear Tangential Flow 旋转直线切向流聚丙烯管式膜器环隙切剖面流场测试
The change law of tangential velocity and radial velocity with along section liquid and gas phases, on-way attenuation law of near-wall region bubble are obtained respectively through statistical experimental data. 通过计算,获得了水相及气相的切向速度和径向速度沿断面的变化规律;获得了近壁区域气泡的沿程衰减规律。
Tangential and radial components of time-averaged velocity in section ⅳ,ⅵ and ⅷ of a volute of centrifugal pumps pumping high viscous oil with viscosity 48mm2 / s were measured using LDV at best efficiency and part loading points, respectively, in the paper. 本文用LDV测量了最优工况和小流量工况下,输送运动粘度为48mm2/s高粘油时,蜗壳第Ⅳ、Ⅵ和Ⅷ断面内的时均切向、径向速度。
