摘　　要：针对测量木材含水量时失重法耗时,电阻法误差大的缺点,设计了一种利用介电常数原理测量木材含水量的单片机控制的数字式检测仪。该设备不会对木材表面造成任何损伤,且测量误差<8%。Weight loss method is time consuming and resistance method is high in error for measuring the water content of wood. A single-chip-controlled digital detector based on the principle of dielectric constant has been developed. It has been shown that its measuring deviation is less than 8% and it will not damage the wood surface tested.
