Research content and research object. The Coagulant Dosage Automatic Control System is discussed emphatically. Including the relation is put up between target standard and the infection factor by date analyzed chart and educational established and sum up the best working point. The target standard including SS COD and OIL .The infection factor including the dosage of PAC PH Mill INTENSION and TIME. On the basis of craft character and control request, it makes a selection of scheme to the whole control system. Finally a scheme is chosen and described as follows: CPU222 of SIEMENS PLC S7-200 is used as the control kernel. V606IC TOUCHER is used as communication man and machine. Controlling pump, compressor, metric pump of system by gathering andanalyzing the flow, PH of raw water .

重点探讨系统的投药自动化，包括系统的数学模型建立的过程，通过数据分析，采用图表和方程式建立系统排放指标(SS、CODcr、含油量)，与各种因素(PAC用量、PH值、搅拌强度、时间)的关系，确定系统的最佳工作点；根据系统工艺特点以及控制要求，对控制系统设计方案进行了选择，确定以西门子PLC(S7-200 CPU222)为控制核心，V606IC10触摸屏作人机界面，通过对原水流量和PH计采样、分析，实现系统中的泵、风机、计量泵等控制；文中从功能上简要地介绍监控系统和给出了自动化原理构成图、PLC软件流程图及部分主要程序。

The experimental system of metal fuel/water ramjet was introduced. The unchoked ramjet of metal fuel containing magnesium can burn steadily after once injecting water. In the experiment, the mass flux of water was stable and the pressure of chamber changed similarly with the secondary chamber.

介绍了金属燃料/水冲压发动机试验系统，采用非壅塞式构型实现了镁基金属燃料发动机一次加水后稳定燃烧，试验中进水流量稳定，补燃室与燃烧室压强变化相同。

First, the mechanism of local head loss is clarified from the theory of plane flow and vortex; and the relationship between local head loss coefficient and barrier-discharge of pile permeable groins is derived.

首先，应用平面绕流与旋涡理论阐明其局部水头损失的机理，导出了桩柱透水丁坝局部水头损失系数与阻水流量的关系式。

Then through combining the experiment data with the existing calculation formula for barrier-discharge, an empirical formula that can be used to calculate local head loss coefficient of pile permeable groins in the non-submerged condition is obtained.

而后利用已有的桩柱透水丁坝阻水流量计算公式结合试验资料，得到了计算单个桩柱透水丁坝在非淹没状态下局部水头损失系数的经验公式，该公式计算值与实测值符合良好，可为透水丁坝水力特性的进一步研究提供参考依据。

This requires a water temperature-control system, usually consisting of a water pump, filter, heat exchanger, and valving to control chilled water input.

这就要求一个水温控制系统，通常包括水泵、过滤装置、热交换器、阀门以控制冷却水流量。

On average, plantations cut local stream flow by more than 50%.

平均而言，植树使当地水流量的减少幅度超过了 50%。

Otherwise, due to different water flow in winter summer air-conditioning, and simple set up in the air conditioning fixed end of the dynamic flow balance valve is not possible to satisfy the water balance of the two seasons.

否则，由于冬季夏季空调水流量不同，而简单在空调末端上设置固定流量的动态平衡阀是不可能满足两个季节的水量平衡的。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
