According to the problem about present utilization of air temperature and rainfall factors to build a moutainous river region lunar evaporativity computing model, inducting the factors of time, air temperature and water, this paper gives a prognostic model with good fitting precision.

A 35 years series of monthly data of ten weather stations and twenty nine evaporation stations in and nearby the Huaihe basin are selected for analysis, which shows a regional distribution regularity and correlation between monthly evaporation and seven meteorological factors significa.

Based on the various environments of ocean voyages,the impact on refrigeration plant′s economy is analyzed with elements as evaporating pressure and condensing pressure.

It presents that the ratio of the condensing pressure to the evaporating pressure may turn out the instruction of the system s defrosting control.

Two major factors, the circulating mass of refrigerant and the cooling load, which influence on the evaporating pressure of vapor compression refrigeration cycle were analyzed thermodynamically in this paper.

In this paper, concerning the forces distribution and surface evaporation effect, a evaporation drag model for one high temperature sphere penetrating the li.

Impact of Temperature change on Potential Evaporation in Yellow River Basin;

The gray relevancy analysis was used to analyze the influence factors of potential evaporation on Hotan oasis.

Base on the meteorological data from 1954 to 2003 in Hotan oasis,the grey relevancy analysis was applied to find out that the air temperature and relative humidity are the main factors for potential evaporation,and the multiple linear regression model was established.
