  但对于悬浮液，外旋流中流体的旋转确实起到了强化微滤的作用。
• In sum , in the case of laminar flow , the outside helical flow would have a little influence on mf of purity water
  总之，在层流条件下，对于纯净水的微滤，外旋流的方式对微滤通量的影响并不显著。
• So it should be pointed out from the above analysis that to make the module operate better , it is the better choice to ensure the flow in the annular gap of it to be a turbulent flow
  同时也需指出的是，为使外旋流的方式较好地达到强化微滤的目的，建议采用一定流量下的湍流方式较为合适。
• The key problems for mf are concentration polarization and membrane fouling . mf assembly with outside helical flow is a new kind of equipment which can enhance permeate flux by means of the operating principle of a hydrocyclone . and up to now many researches of it has been mainly done experimentally
  外旋流式膜器巧妙地将水力旋流器的原理与管式膜器微滤相结合，是一种新的强化微滤的膜器结构，目前对其膜器环隙内的流场分布及分离性能研究均处于起步阶段，且都以实验研究为主。
• ( 4 ) the conditions of no particle deposition or making deposited particles move along the membrane surface were determined with the help of the analysis of forces acting on particles , from which , it may be considered that in the helical flow these conditions would be easier to reach than in the axial flow . when these conditions be satisfied in the whole region , there would be no or only a dynamic cake on the membrane surface . in addition , to ensure a long time steady microfiltration , sometimes over - high flux should be avoided
  ( 4 )通过颗粒受力分析，推导出外旋流方式下颗粒不沉积膜面的条件和已沉积颗粒沿膜面滚动的条件，认为从减小颗粒的沉积到促使已沉积颗粒沿膜面的滚动等方面，外旋流方式相对外轴向流较容易实现，当膜面上所有点上都满足上述条件时，在膜面上将无滤饼或形成一阻力较小的动态滤饼层。
• The main contributions of this work are included as follows : ( 1 ) numerical tests of the outside axial and helical flows were carried out respectively . the velocities and pressure profiles and shear distributions have been obtained and they were compared due to the different flow field . it is concluded that when no particles are deposited , the helical flow would lower the pressure on membrane surface to some little extent but not markedly
  ( 1 )对外轴向流和外切向流两种方式下膜器环隙内流场进行变参数数值实验，作出流场及切应力的分布规律，分析无颗粒沉积时层流条件下流动结构对过滤通量的影响，认为：采用外旋流的方式将对膜面压力有削弱作用，但并不明显。
