10.②Moisture content had a significant effect on the results of stress wave(FAKOPP) and ultrasonic wave(PUNDIT), with the decrease of moisture content, dynamic MOE wasmore increasing. But significant relationships were evident between dynamic MOE at different moisture contents.
②含水率对应力波法(FAKOPP)和超声波法(PUNDIT)测得的动弹性模量影响显著,动弹性模量随含水率的降低而增大,虽然在不同含水率条件下动弹性模量差异显著,但它们之间均显示了很好的相关性。
