<正>本文利用干缩法、力学法、电学法分别对针叶树马尾松、阔叶树钩栗的纤维饱点作了测试,得出了与经典的纤维饱和点相近的数值,并对干缩法、力学法、电学法的测试方法作了探索。通过实验曲线和理论推导得出了干缩法测定纤维饱和点的简便公式,它不仅减轻了测量的工作量,而且进一步提高了测量精度。同时,对这三种测定方法的利弊进行了较系统的分析和比较。

The fibre saturatin point (F.S.P) is the decisive factor in the main properties of wood i, e., wood shape, its mechanical properties and electric conductibility etc. F. S. P. of wood of coniferous. Pinus massoniana and broadleaf Castanopsis tibetana were measured seperately by drying-contracting, mechanical and electrical means resulting in values similar to the classical F. S. P. Research on these three new methods were also made. Based on experimental diagrams and calculated facts, a simple formula for the drying-contracting method has been obtained, which can not only cut down work hours, but also raise measuring accuracy. Advantages and disadvantages of the three methods have also been analyzed and compared in a systematic way.
