例句与用法

1. 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
   尼龙6 / a12o :复合材料的加工性能研究表明:随着纳米a12o3的加入，复合材料的熔体流动速率下降，纳米a12o3含量越大，下降越明显，即队6 / a12o3纳米复合材料的加工性能越差;随着纳米a12o3的加入，复合材料的转矩和塑化时间都增加，当含量小于巧phr时，队6复合材料的转矩增加幅度不大，当含量超过15phr后，转矩急剧升高。
2. Nano - al2o3 particles which are embedded in the matrix can impart additional strength to the composite and act as bearing of stress . furthermore , these organically - treated particles can effectively link the molecular chains of pa6 , and this state is similar to physical crosslinking joints . all these together contribute to the improvement of mechanical properties and hardness
   硬度试验表明，随纳米al _ 2o _ 3填充粒子量的增加，材料的硬度呈现增加趋势，这主要是因为纳米al _ 2o _ 3在尼龙6中类似于“物理交联” 、充当刚性支撑点作用，从而使尼龙6的硬度提高。
