二次成核 meaning in Chinese

secondary formation of nuclei
secondary nucleation

The sem images of diamond film shows that diamond films are stacked with regular ranged and about 200nm ball - like diamond secondary nucleation particles . the diamond films show no well - faceted particles
Sem照片表明所得金刚石薄膜表面是由规则排列、尺寸200nm左右的二次成核晶粒堆积形成，金刚石晶核呈球状，没有明显的刻面特征。
The experimental results show that : solution , nucleation and crystal growth are a continuous process . the induction effect is not apparent in the ethylene hydrate formation . the kinetic curves of ethylene in gaseous condition are very smooth with second nucleation happened in lower temperature and higher pressure
实验结果表明：乙烯水合物生成的溶解、成核、生长的进行是一连续的过程，诱导过程不明显甚至消失；常规条件下的乙烯动力学为一光滑连续的曲线，在较低温度和较高压力下会有二次成核现象；近临界条件下乙烯生成水合物频繁出现二次成核现象；超临界条件下的乙烯由于其特殊的性质而使生成动力学行为变得更加复杂。
