1·All investigators in mass transfer assumed plug flow of gas in packed beds.

所有传递问题的研究者都假定在填充床层中的气体为活塞流。

2·In this paper, a class of more general plug flow reactor model is discussed.

本文考虑了一类较一般的塞流反应器模型。

3·No obvious change is observed for the transition between plug flow and slug flow.

研究中没有观察到表面性剂对塞状流与弹状流转换的影响。

4·The flux in the riser reactor is close to plug flow, which greatly demotes the back mixing.

并且使提升管反应器的流型更加接近活塞流，进一步减少返混。

5·Plug flow reactor(PFR) and Continuous stirred tank reactor(CSTR) were studied to compare their performance for treating dairy manure.

对推流式反应器（PFR）和完全混合式反应器（CSTR）用于牛粪液厌氧消化的性能进行了比较研究。

6·Although only heat balance of plug flow reactor was discussed in this article, the method could be applied in other types of reactors.

作者论述谨以平推流反应器为代表，但其方法不失通用性，可望在反应器热量衡算中广泛应用。

7·The first reactor is approximately ABR-type reactor, the second is a horizontal plug flow reactor, the third is the sub-region reactor.

第一种反应器近似于ABR式的反应器，第二种反应器是水平推流折板反应器，第三种是分区域式反应器。

8·Wall shear stress method integrates the plug flow displacing, the low speed displacing and the turbulent flow displacing methods in theory.

壁面剪应力设计方法，从理论上把塞流顶替、低速顶替及紊流顶替技术统一起来。

9·Mathematical models for Fluid Catalytic Cracking (FCC) riser reactors were built generally on the basis of assumption of plug flow pattern within risers.

催化裂化提升管反应器数学模型基本上都是基于平推流反应器的假设建立起来的。
