对塑料密度测试结果变化的分析

The result analysis of the changing in the plastic density testing

本文针对塑料密度测试结果的几点变化进行分析;密度梯度柱的配置、试验样品的处理过程、样品的制备过程、载荷等、实验环境、化验员的操作、数据的处理等将影响实验结果。

this article analyzes several plastic changes in the density of the test results, several plastic changes ,such as density gradient column configuration, the test sample processing, sample preparation, loading, experimental environment, the operation of laboratory technicians ,data processing, etc., will affect the experimental results.
