摘要:

针对目前国内外金属电导率检测仪器必须由标准试块标定,且检测对象限制在所给标准试块的电导率范围内的状况,从理论上提出了一种检测金属电导率的新方法,即根据已知的散射场阻抗值,采用数值计算法反推出金属的电导率,以克服现有金属电导率检测仪器必须采用标准试块标定的局限性,扩大了被检测材料的范围,研制出实验性的电导率检测仪器.使用该仪器进行的实验表明,该检测方法可行,检测仪器可靠.

Abstract:

In view of the current situation that metal conductivity testing instruments at home and abroad must be calibrated by standard test blocks, and the detection object is limited to the conductivity range of the given standard test block, a new method for detecting metal conductivity is proposed in theory, that is, according to the known scattering field impedance value, the conductivity of metal is reversed by numerical calculation method, so as to overcome the limitation that existing metal conductivity testing instruments must be calibrated by standard test blocks, expand the scope of tested materials, and develop experimental conductivity detection instruments. The experiments carried out with this instrument show that the detection method is feasible and the detection instrument is reliable.
