常用的腐朽木材检验方法有两种:一种是用耳朵听声波进行判断的简单方法,另一种是干脆用斧头砍,找出腐朽部分的方法。这两种方法都是不能令人满意的。下面介绍一种新的检验方法。在距地面几吋的树干上,在直径方向加以振动,测量振动的传播来检测木材内部。测量系统如图1 Commonly used decaying wood testing methods are two kinds: one is to use the ear to listen to sound waves to determine the simple method, and the other is simply cut with an ax to find the decaying part of the method. Both of these methods are unsatisfactory. Here’s a new test method. On the trunks a few inches from the ground, vibrate in the diameter direction and measure the propagation of vibrations to detect the interior of the wood. Measurement system shown in Figure 1
