phr meaning in English
PHR ＝peak height ratio 峰高比。
Examples
- All along or ( informal ) right along adv . phr
自始至终；一直就；从开始便。 - When incorporation content of nano - al2o3 is 20 phr , fillers show conglomeration , which reduces the ability of fillers to link the molecular chain of pa6
因此，为了提高填充粒子与基体的结合能力，有效的降低材料的磨损，对填充粒子作有机化处理是必要的。 - The tem analysis of pa6 composites shows that optimal incorporation of nano - al2o3 into pa6 is at 10 phr of nano - al2o3 , and that fillers can equably disperse in matrix
另一方面，透射电镜分析表明，添加量为10phr的试样中纳米a12o3粒子可以在尼龙6基体中均匀的分散。 - Research shows that absorption properties of composite powders are better than those of single absorber . the minimum reflectivity of 25 phr cb can decrease from - 10 . 54db to - 28
通过对复合粉体的吸波性能的研究，结果表明复合粉体的吸波性能优于单一吸波剂的吸波性能。 - Conglomeration of fillers also easily fall off from the matrix , and all these result in wear mass loss increasing . the worn surfaces of the composites having 5 phr , 10plir , 20 phr nano - al2o3 are respectively studied by using the scanning electron microscopy ( sem )
另外，在相同滑动条件下，随着粒径的增大，尼龙6 / a120 :复合材料的磨损量上升，纳米级粒子填充的复合材料较微米粒子填充的复合材料耐磨性能要好。
