干湿球湿度计

Rna - Rns, see "Partitioning of net radiation", for multiple plants the fraction of radiation to each plant is calculated in the radiation section, see "Partitioning of radiation between plants", es is the vapour pressure at saturation, ea is the actual vapour pressure,ρa is air density, cp is the specific heat of air at constant pressure, Lν is the latent heat of vaporisation,Δ is the slope of saturated vapour pressure versus temperature curve,γ is the psychrometer "constant", rs is an "effective" surface resistance and ra is the aerodynamic resistance.

潜在蒸腾量 Etp 根据Monteith(1965)给出的彭曼联合方程形式计算：式中： Rn 为对于蒸腾的有效净辐射量(也就是 Rna - Rns ，见"净辐射划分"-Partitioning of net radiation，对于多重植被，每一株植物的辐射比率的计算见辐射一节的"植物间的辐射划分"Partitioning of radiation between plants)； es 为饱和水气压；ea 为实际水气压；ρa 为空气密度； cp 为常压下的空气比热；Lν为汽化潜热；Δ为与温度曲线饱和水气压关系曲线斜率；γ为干湿球湿度计"常数"；rs 为"有效"表面阻力；ra 为气动阻力。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.
