When pH is litmusless, the purification efficiency is the largest. The unhomogeneity of liquid flow results in the uneven biofilm growth. The flow resistance after start-up is significantly larger than that before start-up, whichprovides a method to monitor the biofilm growth.3、The packed bed is simplified to a series of straight capillary tubes covered by the biofilm. The two-phase flow and mass transport, biochemical reaction kinetics, and the limitation of oxygen are taken account of in this model. The results of model are basically in agreement with the experimental data.

通过观察还发现，由于液体分布不均，生物膜在滴滤塔内生长分布不均，并且挂膜后，滴滤塔的孔隙率减小，两相流动阻力比空塔时的大，可采用流动阻力的变化作为判断挂膜成功与否判据。3、首次将多孔填料塔简化成多个竖直毛细管并行排列构成的填料，应用两相流理论，结合生化反应动力学，并考虑氧的限制，建立了一个生物膜滴滤塔降解废气的毛细管模型，其结果与实验数据吻合得较好。

In the research on the backward-wave oscillation suppression the startoscillation current which is derived from Two-wave theory approximately is given up. Four typical un-uniform slow wave structures start-oscillation current equations are derived by backward-wave amplifing gain expressions with the Two-wave theory. Then the start-oscillation current rates I〓/I〓 between ununiform circuit and uniform circuit of the four structures have been got.

在返波抑制问题的研究中，从二波理论出发，抛弃了二波理论中从起振条件出发来得到起振电流近似表达式的方法，而是利用二波理论的基本关系式分别推导出了四种典型实用的非均匀输出线路的返波增益表达式，采用计算返波增益的方法来得到四种非均匀输出线路的起振电流与均匀输出线路起振电流的比值I〓/I〓。

A model ejector with variable geometrical throat was designed, then, the processes of start and unstart were investigated, and a criterion was proposed for the condition that second throat is too small to start.

设计了几何结构可调的模型引射器，研究了引射器的启动和不启动过程，提出了判断第二喉道面积过小导致引射器无法启动的判据。

Q2 L5 ^' f* G Wang had been outstanding in the past couple of months. Since the start of July, he was 6-1 with a 2.76 ERA in seven starts. But Wednesday night's outing was ugly from the start, as the first four Blue Jays hitters picked up hits. Matt Stairs led off with a double to right-centerfield, Lyle Overbay singled to leftfield, Alex Rios hit a two-run double to right-centerfield and Vernon Wells hit an RBI single up the middle.

y4 F* K7 d6 '0 }：|王建民加油站王小民在过去2个月以来表现优异，由7月份开始算起，他过去的7次先发拿下6胜1负、自责分率2.76的成绩，但在星期3晚上的出赛中，他从一开始就很难堪，因为前4名蓝鸟打者都敲出安打，第1棒Matt Stairs就打出中右外野2垒安打，Lyle Overbay 打出左外野1垒安打，Alex Rios打出中右外野2分打点的2垒安打，Vernon Wells打出中外野1分打点的1垒安打。

Chris Woodhead, the former Chief Inspector of Schools, who undertook a more limited review of primary teaching for the previous Conservative Government with both Professor Alexander and Sir Jim, said he feared a later start would lead to lower standards: It is reasonable when children arrive at school for the emphasis to be on socialisation, but I see no reason to postpone the start of formal learning.
