The swell factor tends to decrease if the cross section of die crown is large, the die round R is small, the runner is large, the dumping temperature is high and the extrusion speed is low;
口型的冠部截面大、口型圆角R小、流胶口大，排胶温度高，挤出速度慢，则膨胀因数小；
Study on smectite content and the indices for discrimination swell potential indicates that smectite content is a principal factor controlling the swell potential.
蒙皂石含量与各种膨胀势判别指标研究表明，蒙皂石含量是各种膨胀势的主要控制因素。
The factors that affected extrusion swell of thermoplastic starch were optimized by response surface based on the single factor experiment.
在单因素试验的基础上，利用响应面分析法对影响热塑性淀粉挤出膨胀率的因素进行优化。
