The reason is many sided: 1 student and parent think " miscalculate " irrespective, as long as next time attentive dot went. The student allows to use a calculator in 2 education, the student had to the calculator depend on, often abandon when encountering seemingly complex calculation think, use a calculator directly, for instance 618, do not know to change brief into 13, achieve a result with the calculator directly however 0.33. Phase of 3 high school trains a student " put forward, analysis and the ability that solve a problem " the demand is higher and higher, of the train of thought that inscribes to solution in classroom education, thoughtway many somes more tuitional, and to operation ability, because the student has certain base, loosened with respect to some then. 4 emphasizes the training of all sorts of thinking ability overly, the training of operation ability has the suspicion that should try education it seems that, this also is one of reasons. The operation in 5 maths, no matter be numeric computation, return be algebraic type to be out of shape figure, photograph of the train of thought that inscribes with new knowledge, new solution, skill is compared and character, appear more as dry as a chip, the student does not have interest.

原因是多方面的：1学生和家长都认为"算错了"没关系，只要下次细心点就行了。2教学中答应学生使用计算器，学生对计算器有了依靠，在碰到貌似复杂的计算时往往舍弃思索，直接用计算器，比如618，不知化简成13，而是直接用计算器获得结果0.33.3高中阶段培养学生"提出、分析和解决新问题的能力"的要求越来越高，课堂教学中对解题的思路、思想方法的讲授多一些，而对于运算能力，因为学生都有一定的基础，于是就有些放松了。4过分强调各种思维能力的练习，运算能力的练习似乎有应试教育的嫌疑，这也是原因之一。5数学中的运算，不管是数值计算，还是代数式的变形演算，和新的知识、新的解题的思路、技巧相比较而言，显得比较枯燥，学生没有喜好。

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。

Why? When I was in Montpellier, I have seen so many different things and I have encountered so many people from various countries and backgrounds, so during that period, I had a kind of illusion that I did change a lot in terms of the way of living and also the value and expectation that I weighted myself and put on me.

但是现在的问题是：我有很多的梦想，现在是根本就没有道路，无奈之中，还是要捡起"努力吃苦"的征程理念，但是，我的心，我的内心，早已没有了那封坚定和执着，我能否还能应对以后的挫折和压力？有点"心有余而力不足"的感觉。
