second liquid meaning in English
两次流
Examples
- The second liquid crystal cell we have studied is the cell filled negative liquid crystal mbba that aligns along the parallel to the plates of liquid crystal cell
第二种液晶盒是平行排列液晶盒,中间依然充满负性液晶mbba 。 - For heterogeneous azeotropic distillations , three phases , one vapour phase and two liquid phases , can coexist . the existence of the second liquid phase could change the hydrodynamic behaviour and therefore influence the separation efficiency
对三相共沸精馏过程而言,一个汽相和两个液相形成汽液液三相共存现象,第二个液相会或多或少地改变精馏过程的流体力学特性并最终影响过程的传质分离效率。 - The development of mass transfer in the system of vapor - liquid - liquid three - phase distillation from trays was introduced , the effects of the hydrodynamic conditions e . g . vapor velocity and ratio of liquid to vapor loading and physical properties of liquid phase , including surface tension , interfacial tension , viscosity or dispersion viscosity , density , relative volatility etc . and the volume ratio of oil to water on mass transfer were discussed systematically , the influence of the second liquid on mass transfer efficiency was also investigated , a gnat deal of viewpoints and suggestions having been put forward in this paper are significant important for optimizing design of distillation tower
摘要介绍了气液液三相精馏塔板传质性能研究的进展情况,讨论了气速、液气比等操作条件,表面张力、界面张力、液体的粘度或分散粘度、密度和相对挥发度等物系性质以及油水体积比等多种参数对传质效率的影响,探讨了第二液相的存在对传质的影响,文中的许多观点获和建议对于优化精馏塔的设计具有重要的指导意义。
