一种简单、经济的测定硬材密度的方法木材的密度是木材性质的一项重要指标，根据它可以估计木材的重量、判断木材的工艺性和物理力学性质（如：强度、干缩及湿胀等），因此，它也是一个一直受到树木遗传学家重视的指标。目前人们测定木材的方法有：直线测量法、水银测容器... A Simple and Economic Way to Determine Hardwood Density Wood density is an important indicator of wood properties based on which it is possible to estimate the weight of wood and to determine its technical and physical properties (eg, strength, shrinkage and wetness Inflation, etc.), so it is also an indicator that has long been valued by tree genetics. At present, people determine the method of wood are: linear measurement method, mercury measuring container ...
