Study on the model of return water quality of irrigation in farmland 农田灌溉退水水量水质平衡模型研究
Human beings and animals also return water to the air through their skin 人类和动物也是通过皮肤把水分散发到空气中的。
Points out problems in setting expansion joints for supply and return water risers 摘要指出了在供回水立管中间设置伸缩节存在的问题。
Presents the on - off control mode of refrigerating machine by supply and return water temperature difference and load proportion with an example 摘要以具体的工程实例介绍了利用供回水温差和机组负荷百分数进行机组台数启停控研究制的方法。
High temperature water - source heat pump can reclaim loss - grade heat that is produced when energy - changed device such as boiler is operating , anti the return water of district heating supply system is heated 摘要利用高温水源热泵设备可回收锅炉等能量转化设备产生大量的低温馀热,提高其温度用于直接供热。
Presents two common heat recovery methods for water cooling chillers . recommends the control scheme by monitoring the return water temperature . presents two design schemes for chilled water systems 摘要介绍了两种常见的水冷冷水机组热回收方式。推荐采用热水回水温度控制方案。介绍了冷水系统的两种设计方案。
By adding scale inhibitors , scaling decreases markedly in the return water system and the dust collector of the ende pulverized coal gasifier , and the safe and stable operation cycle is prolonged in the gasifer and the ash water system 通过使用阻垢剂,回水系统及恩德粉煤气化除尘装置结垢明显减轻,延长了气化装置及灰水系统安全稳定运行周期。
The water that plants use also returns to the air . a plant has in its leaves small openings through which water vapor leaves the plant . a large tree may lose seventy gallons of water each day . human beings and animals also return water to the air through their skin 植物使用的水份也会返回大气中.水蒸汽会通过植物的叶子里的细微孔洞散失.一颗大树每天可能会损耗70加仑水.人类和动物也会通过他们的皮肤将水份排到大气中
