用体积膨胀法测量了几种润滑剂在1.75 Gpa压力下的粘弹性转变，在0.2~500 kHz频率范围内测量了五种流体在大气压下的介电转变，并在相同频率范围内测量了两种流体在0.55 Gpa压力下的介电转变。恒速膨胀转变、恒速介电转变和恒粘变线在温度-压力图上基本上是平行的。
Viscoelastic transition measurements of several lubricants by volume dilatometry to pressures of 1.75 GPa, dielectric transitions at atmospheric pressure on five fluids in a frequency range of 0.2 to 500 kHz and on two fluids in the same frequency range to pressures of 0.55 GPa are reported. Lines of constant rate dilatometry transition, constant rate dielectric transition and constant viscosity are shown to be essentially parallel on a temperature-pressure diagram.
