摘　　要：用排除液体质量的办法,测定了异形聚乙烯塑料的密度、用误差分析证明了该方法是正确可行的.实验结果表明,通过筛选恰当的试剂,选择合适的测试手段,不经制样,可以获得精确的实验结果.An ordinary method, which is usually used to test the density of liquid, was employed to detect the density of heterotypic polythene plastic. It was testified by a quantitative error analysis that a correct result could be obtained by using the method. And the experiment result shows that it is true if a suitable solvent is selected.
