phr 中文意思是什麼
phr
解釋
PHR ＝peak height ratio 峰高比。-
All along or ( informal ) right along adv. phr
自始至終；一直就；從開始便。 -
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，為了提高填充粒子與基體的結合能力，有效的降低材料的磨損，對填充粒子作有機化處理是必要的。 -
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，透射電鏡分析表明，添加量為10phr的試樣中納米a12o3粒子可以在尼龍6基體中均勻的分散。 -
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
通過對復合粉體的吸波性能的研究，結果表明復合粉體的吸波性能優于單一吸波劑的吸波性能。 -
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，在相同滑動條件下，隨著粒徑的增大，尼龍6 / a120 :復合材料的磨損量上升，納米級粒子填充的復合材料較微米粒子填充的復合材料耐磨性能要好。 -
The results show a few grooves appear on the worn surface of the composites which contain 10 phr nano - al2o3 there are a great many grooves on the worn surface of the composites containing 20 phr. in addition the deeper cracks also appear. this shows that excess nano - al2o3 particles ca n ' t improve wear properties of pa6 ' s. the proper content of nano - al2o3 in the matrix can enable the molecular chains of pa6 to produce closed joints which resemble the physical crosslinking
尼龍6 / a12o :復合材料的加工性能研究表明:隨著納米a12o3的加入，復合材料的熔體流動速率下降，納米a12o3含量越大，下降越明顯，即隊6 / a12o3納米復合材料的加工性能越差;隨著納米a12o3的加入，復合材料的轉矩和塑化時間都增加，當含量小於巧phr時，隊6復合材料的轉矩增加幅度不大，當含量超過15phr后，轉矩急劇升高。
