本研究利用LI-1600气孔计测定了沙坡头试验站土壤水分平衡观测场4个样地的油蒿和柠条的蒸腾。

The strongly nonlinear pore structures of pulverized coals can be described by the fractal theory. The pore fractal dimensions of 10 pulverized coals, which are in the range of 2.572~2.722, were analyzed on a N2 adsorption porometer. The apparent viscosities of coal water slurries were measured on a Haake rotary viscometer.

用分形理论能描述具有强烈非线性特征的煤粉孔隙结构，利用氮吸附仪分析得到10种煤样的孔隙分形维数为2.572~2.722，利用Haake黏度计测量水煤浆黏度，讨论了孔隙分形、水分、氧量和可磨性指数等对水煤浆性质的影响规律，得到相关的拟合经验公式。

Taking the agroforestry modes of Apple+maize,Apple+Mung bean, Walnut+maize and Walnut+Mung bean in western Shanxi province in loess area as subject,the net photosynthetic rate,transpiration rat,water use efficiency and environmental factors of the same crop or fruit in the four were measured with a portable steady porometer(Li-6400) to study their difference and relationship.

以晋西黄土区苹果+玉米、苹果+绿豆、核桃+玉米、核桃+绿豆4种果树—农作物复合模式为研究对象，分析与不同农作物复合的相同果树的光合速率、蒸腾速率、水分利用效率的差异和原因，果树对农作物的遮荫影响，以及净光合速率、蒸腾速率与环境因子的关系。

Many researchers have determined and estimated tree transpiration by using the methods of rapid weighting, steady-state porometer, photosynthesis system, whole-tree photometer, ventilated chamber, weighting potted-plant, sap flow measurements, lysimeter, water balance, energy balance, Bowen ratio, eddy covariance, Penman-monteith Method, and remote sensing.

针对不同的植被覆盖类型，国内外许多研究通过各种手段和方法，如快速称量、稳态气孔计、光合作用测定、整树容器、风调室、盆栽称量、液流测定法、蒸渗仪、水量平衡、能量平衡、波文比、涡动相关、彭曼联合法和遥感等来估算林木蒸腾作用。

In this study, based on the Rnl, extinction coefficient k, transition coefficient of canopy layer stomatic resistance K', aerodynamics resistance ra and rc calculated with the data of Rn, LAI, rsi, the daily transpiration variation of Picea purpurea, Larix principisrupprechtii, Hippophae rhamnoides ,Betula platyphylla and Populus cathayana were studied in Datong County, Qinghai Province. Comparing with the practical transpiration variation measured by Li1600 Steady Porometer, the relative error of this model was less than ±15%, and the results were stabilized and tested by precision analysis.

本研究通过对Rn、LAI、rsi的实地观测，确定了林冠截流净辐射、消光系数、冠层阻力转换系数、空气动力学阻力和冠层整体气孔阻力，对青海大通地区紫果云杉、华北落叶松、沙棘、白桦和青杨的日蒸腾过程进行了模拟，与用快速称重法订正的Li1600稳态气孔仪实测蒸腾结果对比，模拟的相对误差在±15%以内；模型敏感性分析发现，温度、LAI以及rsi是决定模拟结果的主要参数，模型对各参数变化反应不敏感。
