We analyzed and discussed the characteristics of cycle of carbon and water,and after having obtained important physiological parameters based on field experiment,a process-based, multilayer two-leaf model which calculates energy and material cycle separately for sunlit and shaded leaves was developed,then characteristic of CO_2 fluxes above the canopy was simulated.The main results are as follows:1.Characteristics of carbon and water cycle in the relationship of leaf photosynthesis -stomatal conductance-transpiration.

本研究以冬小麦为研究对象，利用LI-6400R光合—蒸腾测量系统、LI-6400-09土壤呼吸室和禹城生态试验站涡度相关系统等高精度仪器设备，对2007年和2008年小麦拔节至乳熟期间涉及碳、水循环过程的叶片光合—蒸腾作用、土壤呼吸作用及相关农田气象要素和植被特征进行了野外试验测定和分析，在试验观测基础上提取了重要生理参数，建立了基于过程的农田与大气间物质输送和能量交换的多层—双叶模型，并对2008年试验期间冠层上方碳通量特征进行了模拟，试验分析和模拟的主要结论如下：1。

It can freely set the tube voltage and tube current of the instrument, which results in clearer aim of the testing of the content of the elements in the samples.

An instrument for measuring strain in a surface.

测量表面张力的仪器。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
