摘　　要：本文论述了模塑聚苯乙烯泡沫塑料的导热系数测定所用的设备、试验原理、检验依据。比较了不同温差下,测得的导热系数值及精密度。结果表明,在选定的温差变化范围内,温差对导热系数没有影响。In this academic thesis, apparatus and trial principle as well as inspect foundation applied in the temperature conductiivity coefficient test of moulding polystyrene foam plastics is expended. Coefficient values and measurement precision tested under varied temperature difference are contrasted . Conclusion is made that under the range of selected temperature difference, temperature difference has no influence upon temperature conductiivity coefficient.
