摘　　要：根据高分子粘弹性理论和松驰运动的原理提出了“热处理－密度试验法”，该方法可将原处于疏松状态的高分子回复到紧密堆砌状态，并测出其真实密度。讨论了影响“热处理－密度试验法”的因素以及该方法在材质相关性检验中的应用。Heat treatment-density test method' has been introduced according to the theory of polymeric viscoelasticity and the principle of macromolecule relaxation movement. The polymer in loose state can be returned to its original tight state by using the method and the real density can be determined. The factors affecting the method and its application to the examination of relativity of material quality have been discussed in detail.
