As can be seen from the literature which I have consulted, universal agreements has been reached as to the mechanism of low-temperature cracking of AC pavement (including contracting cracking cause by one substantial drop in temperature and thermal fatigue cracking). But the research on the low-temperature cracking is still immature up to now, which can justify the absence of related indices of low-temperature cracking of all AC pavement design methods.
但是,从查阅的文献可以看出,对于沥青路面产生低温开裂(包括一次性大幅降温引起的收缩开裂和温度疲劳开裂)的机理,人们的认识是一致的;但是,对于沥青路面低温开裂等问题的研究至今仍不够成熟,世界各国的沥青路面设计方法中均未引入低温开裂的有关指标就说明了这一点。

Jatropha Curcas oil was used as feedstock for producing biodiesel by transesterification,and adding sodium hydroxide,potassium hydroxide or sodium methoxide as catalyst respectively. The optimal conditions were obtained:molar ratio of methanol to oil 6∶1,reaction temperature 60 ℃,reaction time 80 min,mixing intensity 600 r/min,catalyst concentration for NaOH,KOH,or CH3ONa 1.2% of oil weight,The yield of biodiesel was above 97%. The physico-chemical indices of the biodiesel obtained met the quality standard ASTM of USA and DIN V of Germany.

By using the gauge potential decomposition, we have discussed the self-dual equation and its solution in Jackiw-Pi model. We obtained a new concrete self-dual equation and find relationship between Chern-Simons vortex solution and topological number which is determined by Hopf indices and Brouwer degrees of φ-mapping.
