终结讨论:感谢王积强同志对拙文的讨论,由于本人尚在国外学习,无法读到讨论稿中引文,可能对问题缺乏针对性。 (一)一般地说,土壤的总水势由基模势、重力势等组成,在有溶质情况下,还应考虑渗透势、在气压有较大变化情况下,也应该考虑气压势(Pneumatic Potential)。不过在一般情况下,气压变化较小,这种气压势作用可以忽略,这也是我们工作的出发点,其实作为一个比较全面描述,应该考虑热和水的输运是相互交义的、相互影响的。我后来也作了这方面工作,结果证明在亚利桑那这样一个实测条件下,用强迫一恢复方法去描述温度效应是有效的。 至于讨论稿中所提出由于气压变化造成毛细导管堵塞和疏通现象,是很重要的,在目前非饱和土
Ending the discussion: I would like to thank Comrade Wang Jiliang for his discussion on my essay. Since I am still studying abroad, I can not read the quotations in the discussion paper and may not be pertinent to the issue. (A) Generally speaking, the total water potential of the soil is composed of the fundamental mode potential, the gravitational potential, etc. In case of solute, the potential of the soil should also be taken into account. When there is a large change in atmospheric pressure, the Pneumatic Potential ). However, under normal circumstances, small pressure changes, the pressure potential can be ignored, which is the starting point of our work, in fact, as a more comprehensive description, you should consider the transport of heat and water are mutually intersecting, and influence each other . Later, I also did this work, the results prove that in Arizona under such a measured condition, the use of forced-recovery method to describe the temperature effect is effective. As for the discussion paper proposed by the pressure changes caused by the capillary conduit plugging and dredging phenomenon is very important in the current unsaturated soil
