| 摘 要： | 探讨在不同的干燥温度状态下，木材抗弯强度，抗弯弹性模量、横纹抗压强度的变化规律。试验结果显示，在中、低温区域，随着温度的升高，抗弯弹性模量、横纹抗压强镁呈降低趋势；在高温区域，随着温度的升高，抗弯强度被明显削弱，而纹抗压强度则得到增强。

| Abstract: | In this paper,the changing regularity of wood bending,strength, compression strehgth perpendicular to grain in different drying temperature cases was studied. The test results indicated that when the temperature rising, the wood bending strength,modulus of elasticity in bending and compression strength perpendicular to grain had a downward trend when the temperature rising in low and middle temperature zones;In high temperature zone,as the temperature rising wood bending strength was reduced,and compression strength perpendicular to grain had gained in strength. |
