Abstract

The low-frequency (74 kHz) shear elasticity of the homologous series of normal hydrocarbons (alkanes) is studied using acoustic resonance. The shear modulus and mechanical loss tangent are measured, and the relaxation frequency and effective viscosity are calculated. The dependences of these parameters on homologue viscosity are established. It is shown that the mechanical loss tangent of all studied liquids is less than 1, demonstrating that the relaxation frequency is below the experimental frequency.

普通碳氢化合物同构系列的低频剪切弹性

利用声共振研究了同源系列正常碳氢化合物（烷烃）的低频（74 kHz）剪切弹性。测量了剪切模量和机械损失正切，并计算了弛豫频率和有效粘度。确定了这些参数与同系物粘度的关系。研究表明，所有研究液体的机械损失正切都小于 1，这表明弛豫频率低于实验频率。
