摘　　要：ＰＶ技术的计算机处理及其在树木水分关系研究中的应用刘建伟，刘雅荣，王世绩（中国林业科学研究院林业研究所，北京１０００９１）ＣｏｍｐｕｔｅｒＰｒｏｃｅｓｓｉｎｇｏｆＰＶＣｕｒｖｅＡｎａｌｙｓｉｓａｎｄＩｔｓＡｐｐｌｉｃａｔｉｏｎｉｎｔｈｅＲｅｓｅａｒｃ...Based on the mathematic formularization of PV curve,it's shown that PV curve is linear whenpressure p=0.and nonlinear when p>0.At the same time,the new analysis by computer(Schulter,1988)was introduced and applied to Populus simonii data processing.The resultsshow that at the saturated state leaf osmotic potential is 1. 0512MPa,elastic modulus1.7MPa;and at the turgor loss point,the relative water content(RWC),osmotic potentialand elastic modulus are 83.5%, 1. 3478MPa and 0.17MPa ,respectively,In the anal...
