冷却循环

It can be used as dispersant in pour-cooling water if iron and steel plants, and also used together with organic phosphonate and zine salts in circulation cooling water with high hardness and high alkality.

用于钢铁厂淋洗的冷却水，防止氧化铁、化锌和泥沙沉积，以及用于高碱度循环冷却水中与有机膦酸盐、复配的阻垢缓蚀剂。

Fe and Al in the system were removed by precipitation at pH≈5. Co2 was obtained by precipitation at pH=9.5~10, it was then purified by reprecipitation. Co3O4 was obtained by calcining Co2 at 500℃ for 2h, the purity of which was 99.3%. The recovery rate of Co was 97%. Li2CO3 was obtained by adding Na2CO3 to the mother liquor, the purity of which was 97.8%. The one-time recovery for Li was 73%. The mother liquor can be reused after being cooled to below 10℃ and Na2SO410H2O is recovered.

体系中的Fe、Al从杂质在pH≈5时沉淀除去；Co2在pH为9.5~10沉淀得到，经酸溶解后二次沉淀提纯，500℃煅烧2.0h得Co3O4，其纯度达到99.3%，钴的回收率达97%，母液中Li离子加Na2CO3处理，沉淀得Li2CO3，其纯度达97.8%，锂的一次回收率达73%，母液经冷却至10℃以下除去Na2SO410H2O后可循环使用。

It can be driven by low grade energies, such as waste heat and solar energy. In this work, a novel energy efficient air-conditioning system utilizing liquid desiccant is introduced, after the author sums up the previous researches. At first, fresh air from the atmosphere is dehumidified by direct contact with strong liquid desiccant in the dehumidifier; after being cooled by the evaporative cooling sub-system the process air is blown into the air-conditioning space.

在该系统中，环境空气作为新风进入除湿器与除湿溶液接触时被除去部分的水分；干燥的空气再通过蒸发冷却子系统处理，降低温度后送入空调房间达到对室内降温、调湿的目的；吸湿后的除湿溶液被喷入再生塔，在热源作用下再生，这样溶液就可以循环利用。

The air then returns to the central air-conditioning machinery through spaces called plenums to be recooled and recirculated.

空气透过压力通风系统再回到中央空调机，再冷却，然后再度循环。

He has worked up quite a sweat, though,so the portable air conditioner on his belt promptly starts circulating coolant via tiny tubes that run throughout his uniform.

这位班长此时已是汗流浃背，于是腰带上装备的便携式空调器便迅速启动，冷却剂开始在遍布制服的微小管道里循环流动。

Aiming at the problems occurred in the analytical process of determining the total phosphorus in industrial circulating cooling water by ammonium molybdate spectrophotometry and based on the experience summary,the original analytical method has been improved.

针对用钼酸铵分光光度法测定循环冷却水中的总磷在实际分析过程中遇到的一些问题，经过总结经验，改进了原有的分析方法，降低了测定中的干扰因素，提高了一次分析结果的准确可靠性，使分析结果更为准确可靠。

The air for cooling is usually passed through a battery of water jets and dried before using.

这个冷空气的冷却通常可用一组循环水的方法实现，并且使用前一定要干燥。

2 Should ensure that the cooling pond, cleaning, there must be no debris, dirt, every six months to carry out a sea of washing machines, water pipes, to remove scale, it would be specific about 25 kg of hydrochloric acid into the plastic bucket, then on the pump inlet and outlet pipe in plastic buckets together Add to the closure of machine power, a separate 15-minute run to open pumps, hydrochloric acid in the sea in circulation, remove furring.

3.2 应确保冷却水池内清洁，不得有杂物、污垢，每六个月要对机器水路进行一次清洗，除去水管内水垢，具体做法是将25kg左右的盐酸倒入塑料桶中，然后将水泵上的进水管和出水管一并放入塑料桶中，关闭机器电源，单独开启水泵运行15分钟，使盐酸在水路中循环流动，可以除去水垢。

The cooling system is made up of the passages inside the engine block and heads, a water pump to circulate the coolant, a thermostat to control the temperature of the coolant, a radiator to cool the coolant, a radiator cap to control the pressure in the system, and some plumbing consisting of interconnecting hoses to transfer the coolant from the engine to radiator and also to the car's heater system where hot coolant is used to warm up the vehicle's interior on a cold day.

制冷系统是在发动结内部中间和顶部有许多段组成的，一个水泵来循环制冷剂，一个自动调温器来控制制冷剂的温度，一个水箱来冷却制冷剂，一个水箱盖来控制系统的压力，许多泵还包括互相连接的水管输送制冷剂在发动机和水箱之间，或是发动机和汽车的加热系统，当冷天气，加热剂来增加汽车的内部温度。

In the commonly used positive cycle of drilling, the mud pump is to rinse the surface with water medium ─﹑ mud or polymer washing fluid at a certain pressure, through the high-pressure hose taps and drill column ﹑ center hole in the bottom of the direct-drill in order to achieve Cooling ﹑ be cutting down the drill cuttings removal and transport to the surface purpose.

在常用的正循环钻探中﹐泥浆泵是将地表冲洗介质─清水﹑泥浆或聚合物冲洗液在一定的压力下﹐经过高压软管﹑水龙头及钻杆柱中心孔直送钻头的底端﹐以达到冷却钻头﹑将切削下来的岩屑清除并输送到地表的目的。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。

In slot 2 in your bag put wrapping paper, quantity does not matter in this case.

在你的书包里槽2把包装纸、数量无关紧要。
