野村等曾报告压电晶体在KCl溶液中的频移(至2mm)。对于电解质溶液中压电晶体振荡规律的定量研究,未见文献报道。本文采用晶体管振荡电路,研究了石英压电晶体在电解质溶液中的频移特性与规律。发现:晶体频移与溶液电解质浓度有线性关系,其斜率与电解质种类无显著的依赖关系,接地可显著增宽频移线性关系的电解质浓
Nomura et al. Reported the frequency shift (up to 2 mm) of piezoelectric crystals in KCl solution. For the quantitative study of piezoelectric crystal oscillation law in electrolyte solution, no literature has been reported. In this paper, the transistor oscillating circuit was used to study the frequency-shift characteristics and regularity of quartz piezoelectric crystals in electrolyte solutions. It is found that there is a linear relationship between the crystal frequency shift and the electrolyte concentration of the solution, and the slope has no significant dependence on the electrolyte type. The grounding can significantly broaden the electrolyte concentration
