For air-conditioning water system, the transmission power ratio of the total energy consumption increases with the system scale increases.
对于空调水系统来说，输送能耗占总能耗的比例随系统规模的增大而增加。

It also studies the influences of W/C ratio, water reducer, and air- detraining admixture on the porosity and apparent porosity and of porosity and apparent porosity on the intensity.
Concurrently analyzed is that improvement of effective thermal efficiency after rise in compression ratio and water injection is resulted from thermal efficiency promotion of fuel-air ideal cycle.
