It has been shown that by using piezoelectric lateral electric field excited resonators based on X - cut LiNbO, one can determine the octane number of gasoline. The measured dependence of gasoline permittivity on its octane number has shown that there is an ambiguous connection between pointed parameters. We have demonstrated both theoretically and experimentally that the value of the real part of the electrical impedance on the frequency of parallel resonance uniquely associates with the octane number of gasoline contacting the free side of the resonator. At that the frequency of parallel resonance does not depend on permittivity/octane number of gasoline. An example of determination of the octane number of a mixture of two different samples of gasoline is given.
已经表明，通过使用基于X切铌酸锂的压电横向电场激发谐振器，可以测定汽油的辛烷值。所测得的汽油介电常数对其辛烷值的依赖性表明，这些特定参数之间存在不明确的联系。我们已经在理论和实验上证明，并联谐振频率下的电阻抗实部值与接触谐振器自由侧的汽油辛烷值唯一相关。此时，并联谐振频率不取决于汽油的介电常数/辛烷值。给出了一个测定两种不同汽油样品混合物辛烷值的示例。
