研究了无机陶瓷膜处理印染废水过程，考察了膜孔迳，操作条件对处理效果的影响及清洗剂和清洗时间对清洗效果的影响。

The treatment process of dyeing and printing waste water by inorganic ceramic membrane was investigated,the effect of membrane pore size, operation conditions, abluent and cleaning time on cleaning result were studied.

研究了无机陶瓷膜处理印染废水过程，考察了膜孔径，操作条件对处理效果的影响及清洗剂和清洗时间对清洗效果的影响。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
