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。

Peanut or rice wereplanted in the large-scale weighing Lysimeter,pit plots,and standard runoff plots,wherehigh,moderate,and low soil moisture levels were designed as 3 treatments,assemblingwith some instruments such as time domain reflectometry,portable photosynthesis system,dew point microvoltmeter,and porometer.

季节性干旱缺水严重制约着我国红壤区农业的持续发展。1999～2000年在中国科学院红壤生态实验站，利用大型称重式蒸渗仪、测坑小区和径流小区，配合时域反射仪、光合蒸腾仪、水势仪及动态气孔阻力计等仪器，设计高、中、低3种土壤水分处理，进行了花生和早晚稻试验。

The leaf stomata are the route for the uptake of CO2 for photosynthesis.

控制气孔是为光合作用而吸收CQ2的通路。

Stomata : mainly at lower epidermis, for gases exchange and water loss by transpiration.

气孔 ：主要在叶底表皮，用作气体交换和水分的蒸发。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
