The results indicate that the μ of the asphalt mixtures has significant effect on the maximal lateral and shear strains. When the modulus ratio of the top and middle lagers is less than 0.8 and the μ of the asphalt top layer increases to a certain extent, the asphalt mixtures around the edge of wheel mark tend to flow towards both sides of the rut under the action of load, leading to the unstable rut.

结果表明，沥青面层的泊松比对沥青路面结构的最大横向应变和最大剪应变有显著影响：当上中面层模量比小于0.8且沥青面层泊松比增大到一定程度时，轮迹带边缘的沥青混合料在荷载作用下有向车辙两侧流动的趋势，容易产生失稳性车辙。

Our investigation has shown that:ⅰ there was an interference effect between the incident and reflected matter waves as all the atoms in BECs were coherent;ⅱ considering the rotation of a vortex, the nonuniform velocity distribution along the surface would play an important role in the quantum reflection process. For example, they would change the characteristics of the interference fringes between the incident and reflected matter waves;ⅲ the reflected vortex became unstable for sufficiently low incident velocity or strong interaction. This sort of instability physically originated from dynamics excitations induced by the atomic interaction in the quantum reflection process.

我们的研究表明：ⅰ由于相干性质的存在，在涡旋与固体表面相互作用的过程中，被固体表面反射回去的部分与正在入射的部分在空间叠加后一定会产生清晰的干涉条纹；ⅱ由于各向异性的速度分布，涡旋的反射率也呈各向异性，因此反射回来的部分与入射部分形成的干涉条纹宽度以及疏密程度与入射速度以及速度各向异性的程度有关；ⅲ由于玻色凝聚体中原子间相互作用的存在，反射过程中凝聚体会产生激发，破坏涡旋的结构，使得反射后的涡旋不再是中心对称。
