以俄罗斯落叶松为对象，采用稳态平板导热仪测量其在35、50、65及80℃时，绝干—71％含水率条件下的导热系数，进而探讨木材弦径向导热系数在各影响因素下的变化规律。结果表明：俄罗斯落叶松木材导热系数随含水率的降低而减小，随温度的升高而增大，径向导热系数变化范围在0．0376～0．1521 W· m－1· K－1，而弦向则在0．0488～01．121 W· m－1· K－1；径向导热系数大于弦向，二者比值在1．119～1．738；根据实验所得数据模拟得出温度和含水率对导热系数的二元回归方程，弦径向方程的计算值与实验值的相关系数分别为97．8％和99．2％。

We measured the conductivity of Russian Larch with the steady-state plate thermal conductivity apparatus under differ-ent temperatures of 35℃, 50℃, 65℃and 80℃ and the moisture content from oven dry to 71%along tangential and radical grain directions , and studied the variations of every influencing factor .The thermal conductivity decreased when re-ducing the moisture content and increased when increasing the temperature .The range of radical conductivity was between 0.037 6 and 0.152 1 W· m-1 · K-1 , while tangential conductivity was between 0.048 8 and 0.112 1 W· m-1 · K-1 .Ther-mal conductivity in radical direction had a greater value than that in tangential , and the ratio of conductivity of two direc-tions was in 1.119-1.738.We simulated a ternary linear equation in tangential and radial direction , respectively , with ex-perimental data .The average correlation coefficients between calculated values and measured ones of tangential and radial direction were 97.8%and 99.2%, respectively.
