摘要: 野村等曾报告压电晶体在KCl溶液中的频移(至2mm)[1]。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。

Abstract: Solution properties of the piezoelectric quartz crystal were studied using a transistorized oscillator. Frequency shift increases linearly with the increasing electrolyte concentration with a slope which is common for the electrolyte salts. Grounding the detection cell, it results 'in a wider linearity range. Anew frequency shift method has been developed for rapid determination of total electrolyte concentration in natural waters.

Key words: Piezoelectcic crystal, Frequency property, Electrolyte solution, Salt content in natural water
