| 6. | . thanks to the semi - rigity material ' s easy obtaining , simple technics , high rigity and intensity , but low pric , the semi - rigidity pavement has become a kind of main form in chinese high grade pathway .
由于半刚性材料易于就地取材、工艺简单、强度和刚度好，造价又低，故这种刚柔结合的半刚性路面结构已形成一种普遍使用的形式。 |
| 7. | The reflective cracking and the surface cracking in the semi - rigid pavement are common under the sudden temperature changed and continuous low temperature for its sharp contraction characters produced by the change of temperature and humidity
由于半刚性材料的温缩性和干缩性，路表温度的骤然升降和持续低温，使得半刚性路面中广泛存在反射裂缝和表面裂缝。 |
| 8. | ( 2 ) the size reduction of iron particulates is caused by stretching , compression , developing of microcracks and fragmentation during pan - milling . tem shows that a part of the iron particles gets down to 40 ~ 120nm in dimension after 25 cycles of milling is offered
聚丙烯和铁共碾磨30次后，复合粉体的平均粒径为9 . 6微米； pp fe共碾磨25次后，铁的晶粒尺寸减小为22nm ，刚性材料铁对pp的粉碎具有助磨作用。 |
| 9. | The crystalline structure changes of pp induced by pan - milling were characterized by x - ray diffraction and raman spectroscopy . xrd analyses show that when pp was co - milled with uhmwpe , crystal transformation of pp occurred , its crystallinity and crystallite size decreased , whereas , only slight reduction of crystallinity and crystallite size were observed and no crystal transformation was found when pp was co - milled with wtr chips , and amorphization of pp was strongly enhanced by co - milling pp with iron
采用x -射线衍射研究了聚丙烯碾磨粉碎过程微观结构变化， uhmwpe存在下pp发生晶型转变、结晶度降低和晶粒尺寸减小；弹性材料wtr抑制pp塑性变形，碾磨导致分子堆积有序区域膨胀，晶面间距增大，结晶度下降；刚性材料金属铁与pp产生强烈摩擦，加快晶粒细化，晶格破裂导致非晶化。 |
