杨木干燥基准及其皱缩特性的研究

Study on Drying Schedule and Collapse of Aspen

用百度试验法研究了大青杨、北京杨和山杨等三种杨木的干燥基准和皱缩特性，并对百度试验法中的截面变形评定分级标准进行了修订；采用百度试验法研制的基准对北京杨进行了室干试验，同时研究了北京杨室干过程中的皱缩特性。

The study on drying schedules of 3 kinds of Aspen was made with lOOt testing method, and evaluating standard of cross section deformation was revised. Also, drying experiment of Peking Aspen was conducted according to the schedule obtained through 100℃ test method, and the collapse property of Peking Aspen in kiln drying process was studied.
