介绍了一种简单的毛细管和灯泡汞膨胀仪，用于测量热固性树脂体系在固化反应过程中的比体积，并作为温度的函数。以双酚A型双氰酸酯树脂体系的数据为例，详细介绍了该系统的设计、校准、操作、数据处理和误差分析。特别注意实验困难，如单体/预聚体脱气、真空下填充膨胀计、膨胀计球上固化树脂的粘接变形以及膨胀计球与毛细管的连接问题。©1994 John Wiley&Sons，Inc.1
A simple capillary and bulb mercury dilatometer designed for specific volume measurements on thermoset resin systems during the curing reaction and as a function of temperature is described. The design, calibration, operation, data treatment, and error analysis are presented in detail, with data on the bisphenol A dicyanate resin system used as an example. Particular attention is directed at experimental difficulties such as monomer/prepolymer degassing, filling the dilatometer under vacuum, adhesive distortion of the curing resin on the dilatometer bulb, and the dilatometer bulb to capillary connection problem. © 1994 John Wiley & Sons, Inc.1
