摘要
木材是变异性很强的各向异性材料。适当地确定试样的数量才能既保证试验的精确度,又避免枉费人力、物力。为了修订国家标准《木材物理力学试验方法》中的取样方法,本文分析、比较了国际标准与中国现行标准之不同。
Wood is a kind of anisotropic material which has strong variability, Determining the number of test specimens suitably can reach the target of not only getting the requisite accuracy but also avoiding big waste. For revising the Chinese standard of 'Methods of Testing Physical and Mechanical Properties of Wood', the difference sampling methods between ISO international standard and Chinese standard has been analysed and compared. A sampling methods that is suitable to china′s actural condition and close the ISO international standard has been found.
