【摘要】 分别对新鲜落叶松、毛白杨、杉木、旧落叶松、红松和楠木制作的试样进行了密度、含水率和阻力仪检测试验。结果表明:木材年代对阻力检测值的影响不显著;密度对阻力检测值的影响非常显著;含水率对阻力检测值的影响未找到相应的规律;树种对阻力检测值有一定影响,但相比密度,影响不显著。更多还原

【Abstract】 Density,moisture and resistograph testing of the samples of new Korean larch,new Chinese white poplar,new common China-fir,old Korean larch,old Korean pine and old machilus were tested in this paper.The results of the experiment indicates: time does not influence the result of resistograph obviously;density influences the result of resistograph obviously,the rules that moistrue influences the result of resistograph have never been founded;the species influence the result of resistograph,comparing denstiy,however,it does not influence the result of resistograph obviously.更多还原
