2、,只需一个缘由,那就是小型蒸腾器的原量+降水量蒸腾余量[1]。现就这一表象缘由进行剖析。Intheprocessofdeterminingtranspirationtranspirationissmallinquantity,sometimesforsomeunknownreason,theevapotranspirationvaluesbecomenegative.Calculationformulaforsmalltranspirationtranspirationtoevapotranspiration=:original+precipitation-margin,whichca

4、1小型蒸腾器和蒸腾专用雨量器的区别Thedifferencebetween1.1smalltranspirationandevaporationspecialraingauges 小型蒸腾器为口径20cm、高约10cm的金属圆盆,受水界面较为单一;而蒸腾专用雨量器是由全新不锈钢的口径为20cm的承水器(漏斗)、储水筒、储水瓶几个部件组成,承水器与漏斗连接面不是一个完好无隙的受面体,雨水通过承水器(漏斗)流入储水瓶内,承水器外表和储水瓶都会吸附一些雨水,漏斗与承水器之间的接缝也会收纳一些雨水,结尾形成从蒸腾专用雨量器中量取出的雨量会比实践偏少一些。因为小型蒸腾器和蒸腾专用的雨量器安a装
5、方位不一样,有时因风向的不一样,落入蒸腾专用雨量器中的雨水比落入小型蒸腾器蒸腾皿内的雨水少,相应地,原量+降水量的数值就减小了。Smalltranspirationfor20cmdiameter,heightofabout10cmmetalroundbasin,waterinterfaceishttp://www.talwhw.cnhttp://www.tskeda.cnhttp://www.lwfengxing.comhttp://www.lwgjhc.comrelativelysingle;andspecialraingaugetranspirationisthewaterhold
