nucleation effect meaning in English

成核作用

The wxrd characterization showed that o - mmt possessed obvious nucleation effect on the crystallization process of b - pp . jeziorny and mo methods were used to study the non - isothermal crystallization process . the obtained value of kinetics parameters such as tp , n , zc , t1 / 2 , a h , f ( t ) , e showed that the o - mmt has nucleation effect in crystallization of pp and can increases the crystallization temperature of pp , quickens the crystall ization velocity , decreases the crystallization activation energy of pp but decreases the crystallization degree of pp at the same time
运用jeziorny法和mo法研究了聚丙烯和复合材料的非等温结晶过程，所得到的非等温结晶过程动力学参数t _ p ， n ， z _ c ， t _ ( 1 / 2 ) ， h ， f ( t ) ， e的数值表明，有机蒙脱土的加入可以起到异相成核的作用，从而提高pp的结晶温度，加快pp的结晶速率，降低pp的结晶活化能，但同时也会降低pp的结晶度。
