摘要：

A high-pressure and high-temperature dilatometer was developed by combining an S-type dynamic bellows cell and a high-resolution differential transformer and by setting them separately in two high-pressure vessels. It was revealed that the dilatometer is capable of observing the volume changes through the melting process in a typical polymer, polyethylene, at high pressures of up to 500 MPa.
