The simulated results with this model match well with the results obtained by weighing lysimeter. Because there are not good stomatal models to predict the stomatal conductance, it was inputted from measured results, then the evapotranspiration rate is simulated separately for different times in a day.

模拟的结果与lysimeter的测量结果符合得比较好，但由于没有合适的气孔模型，所以模型中的气孔导度是用测定值代入的，因而模拟的蒸散量不是连续的。

By comparison of MP and PM method, we can't simply evaluate which kind of method is superior or which kind of method calculates the ET0 value big, and we should consider different geography, the climatic conditions and lysimeter experimental result.

仅通过MP、PM公式的计算比较，不能简单地评定哪种公式最优或哪种公式计算ET0值大，应针对不同地理及气候条件，要经Lysimeter的实验结果才能进行率定比较。

This article, through summarizing the progresses in the evapotranspiration (ET0) methods research, analyzes representative ET0 computation methods emphasized on three periods of the world: modificative Penman, Penman-Monteith and standard ASCE-PM. We take 20th century 90's last stages and 21th century initial period's world newest 19 experimental achievements with lysimeter's actual value rating ET0 value as the foundations, analyzing general usage of the ET0 computational method regarding the different climatic conditions. Although the effect of PM method application is desirable in many areas, many local effects are still unsatisfactory; the method MP and so on are more suitable in part of areas; the PM and MP method are not popular, the special attention must be paid to the standard ASCE-PM method. In brief, these kinds of half theory (semi-empirical) methods only suit in certain areas.

通过对ET0计算公式研究进展的总结，分析了在世界上三个时期比较有代表性的计算蒸发腾发量(ET0)的主要公式：修正Penman公式、Penman-Monteith公式及标准ASCE-PM公式；以20世纪90年代末期和21世纪初期世界上最新的19个用Lysimeter实验值率定ET0计算值的实验成果为基础，对于不同气候条件下ET0计算方法的普适性分析评估认为：虽PM公式应用效果较好的地区较多，但也有不少地区效果欠佳，MP等公式在一部分地区较好，PM与MP公式并非普适性的，要特别关注标准ASCE-PM公式，总之，这类半理论公式均有一定的地区性。
