This paper mainly discussed the nucleation and crosslinking modification of polypropylene (PP).

本文主要研究了聚丙烯（PP）的成核改性和交联改性。

Meanwhile,ultrasonic scratching pretreatment was also applied by using diamond powder to enhance diamond nucleation.

当然，用金刚石粉进行超声研磨以提高金刚石 武汉理工大学硕士学位论文 成核密度也是需要的。

Ethanol--ultrasonic Nucleation approach was employed to prepare fructose seeds. The obtained optimal conditions are: supersaturation degree 1.25, ethanol concentration 0.4 ml/g, electric current 0.3 A, ultrasonic treating-time 1min.

首先研究了乙醇——超声波协同起晶法制备果糖晶种的工艺,优化得到的工艺条件为:果糖浆过饱和度为1.25,乙醇对果糖的添加量为0.4 mL/g,超声波频极电流为0.3 A,超声处理时间为1 min。

The results indicate that the sites and modes of 8 phase’s nucleation were related to aging temperature.

结果表明,δ相的形核位置和形核方式与时效温度有关。
