成核密度 meaning in English
nucleation density
Examples
- The three different pretreatment methods were adopted respectively in order to increase nucleation density
为提高金刚石成核密度分别采用以下三种不同的基片处理方法。 - All of them contribute to diamond nucleation and coating adhesion . 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。 - When the third pretreatment method was adopted , microwave input power was 700w , gas pressure was 1000pa and substrate was tangent on plasma ball surface , diamond films showed higher nucleation density by contrast
经过对比采用方案基片处理方式，基片和等离子球处于相切位置时，在微波输入功率700w和反应气压1000pa时沉积工艺参数时，基片成核密度较高。 - Factor contributing to this problem is that the metal cobalt used as the cementing phase easily causes diffusion and dissolution of carbon , promotes graphite growth and inhibits diamond nucleation and growth in the course of competitive growth between diamond and graphitic carbon
其原因是在沉积过程中，基体中所含的钴会引起碳的溶解和扩散，从而导致金刚石成核密度的降低和石墨的形成。 - With plating time going on , the nano - polycrystal gathering grows in two dimensions , and the new nano - polycrystal layer appears simultaneously on the formerly formed nano - polycrystal surface . because the boundary and defect densities in quenched and tempered 45 steel is higher than those in annealed steel , the nano - polycrystal gatherings formed at its surface at the beginning of electro - deposition are more concentrated , and then their size is smaller . the microstructure of the ni - p alloy coating has closed relation with its phosphorus content with the increase of phosphorus content , the microstructure of coating turns from nano - crystalline to the amorphous
随着施镀时间的延长，纳米晶聚晶体在横向二维生长的同时，在纳米晶聚晶体的表面上也进行着三维方向的新的一层聚晶体的生长；在调质态45钢表面，由于其具有比较高的晶界和缺陷密度，因此在沉积初期，纳米晶聚晶体的成核密度也较大，从而在二维方向聚晶体的尺度较小，镀层沉积初期表现为致密细小的鳞片状组织。
