本文描述了一种压缩振动、非共振方法，用于测定聚合物在频率通常在0.01？赫兹到100？赫兹。该方法适用于半刚性聚合物动态储能模量在1？MPa到121？GPa.该方法特别适用于半导体器件动态模量和损耗因子的测量。直角棱柱、圆柱体或管状的硬质塑料，可以方便地用于研究动态特性随温度和频率的变化，通过大多数玻璃？橡胶松弛区（参见？ISO？6721-1）。

This document describes a compressive vibration, non-resonance method for determining the components of the compressive complex modulus E* of polymers at frequencies typically in the range 0,01 Hz to 100 Hz. The method is applicable for measuring dynamic storage moduli of semi-rigid polymers in the range 1 MPa to 1 GPa.This method is particularly suited to the measurements of dynamic moduli and loss factors of semi？rigid plastics in the shape of a right-angled prism, cylinder or tube and can be conveniently used to study the variation of dynamic properties with temperature and frequency through most of the glass？rubber relaxation region (see ISO 6721-1).
