apparent crystal size meaning in English

晶体表观尺寸

By compounding caco3 with pp , the effect of caco3 content , diameter and shape on the crystallization , dispersion morphology and properties of pp / caco3 composites was investigated . the results showed that addition of caco3 into pp decreased the apparent crystal size in perpendicular direction to the ( 110 ) , ( 040 ) and ( 130 ) crystallographic planes of ppa crystal , and with similar uniform dispersion of caco3 , the dominant factor influencing toughness is the diameter of caco3 particles , but not the decrease of pp crystal size . the toughening effectiveness of nano caco3 is obviously better than that of micron caco3
将caco _ 3与pp进行填充复合，研究了caco _ 3含量、粒径及形状对体系的结晶，分散形态及性能的影响，发现碳酸钙的加入使聚丙烯晶型垂直于( 110 ) 、 ( 040 )和( 130 )晶面的表观晶体尺寸减小，揭示了在分散均匀的情况下，影响材料韧性的主导因素不是晶粒尺寸的减小，而是碳酸钙的粒径，纳米张玲：弹性体及无机刚性粒子增韧增强聚丙烯复合材料的研究碳酸钙的增韧效果明显优于微米碳酸钙。
