How to measure and analyze the phenomena in property of pump and hydroturbine is one of the most important field in cavitation and erosion research.

影响水泵与水轮机使用寿命与性能的主要问题是空化空蚀现象，在现场监测与分析水泵与水轮机的空化状态是空化空蚀研究的重要领域。

To pump water with 2 triphase water pumps and 5 monophase water pumps simultaneously, the water surface kept constant when it descended 100mm.

用2台三相水泵和5台单相水泵同时抽水，水面下降100 mm后就不再下降。

This paper has mainly analysedvertical oblique flow circulating pump operation properties. Through monistic flowdesign theory, carried out preliminarily design for impeller, and completedthree-dimensional model analysis through CAD software. With the aid of CFD-FLUENTsoftware platform, have carried out value for flowing imitation in pump, the SIMPLECmethod on unstructural grid has realized pressure the couple of speed, which verified theresult of preliminary design.

本文主要分析了立式斜流循环水泵运行特性，通过一元流设计理论，对叶轮进行初步设计，并通过 CAD 软件进行立体三维模型分析，借助 CFD-FLUENT 软件平台，对水泵内流场进行了数值模拟，利用非结构网格上的 SIMPLEC 方法实现压力-速度的耦合，对初步设计进行计算结果的验证。

Outlet pressure and flow are normally controlled by adjusting valve clearance and it causes considerable energy waste. Frequency control of motor speed is a method of solving the problem. Principle of energy-saving by this method is disserted.

常规的通过调节阀门开启度来达到调节注水泵出口压力和流量的作法，会使很大一部分能量造成浪费，要解决这个问题，可以采取对注水泵进行调速的方法。

The this design basis related standard, in the consideration energy conservation and under the comfortable request's premise, the refrigeration engine room supposes in underground one, selected has opened the advantage factory piston cold water unit, in the refrigeration engine room establishes the circulating water pump, the supplies water pump, to divide the water collector, the zeolite softener and so on supporting facility; The air-conditioning system uses the air blower serpentined to add the new atmosphere system, each has the corresponding new atmosphere unit, the indoor load mainly undertakes by the air blower serpentined.

本设计依据有关规范，在考虑节能和舒适性要求的前提下，制冷机房设于地下一层，选取了开利厂家活塞冷水机组，制冷机房内设置了循环水泵、补给水泵、分集水器、软水器等辅助设备；空调系统采用风机盘管加新风系统，每层都有相应的新风机组，室内负荷主要由风机盘管承担。

The condensing equipment consists of condenser, cooling pump, air ejector and condensing pump.

凝汽设备由凝汽器、冷却水泵、抽气器和凝结水泵组成。

I production and management company of products: water spray nozzle, signal butterfly valves, valve wet alarm, fire pumps engagement, fire hose reel, fire hoses, the use of joint-fire pumps, manual alarm button, fire zone, signal Valve, flow meters and other products.

Discharging ballast water with compressed air needs not to install ballast water pump unit that is necessary for pump discharging and simplifies ballast water pipeline system, reduces ship weight, improves the variable loading capacity of marine platform and finally promotes economic benefits.

采用压缩空气来控制与调节半潜式海洋平台或工作船舶的上浮及下潜，是借鉴潜水艇沉浮原理而设计的一种新型压载水排放模式，使用压缩空气排放压载水，免除了使用水泵排放所必须安装的压载水泵组并简化了压载水管系统，减少了船舶的自重，提高了海洋平台的可变载荷量，提高了经济效益。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
