This paper sums up and evaluates many kinds of adhesion methods of asphalt to aggregate both at home and abroad . base on making use of the theory of gray relation degree , the correlation between different adhesion experiment results and water stability of asphalt mixture is evaluated . the result indicate that immersion test has the best relation degree with water stability of asphalt mixture 本文在归纳、总结国内外沥青与集料“粘附性”试验方法的基础上，运用灰关联方法，分析了不同的沥青与集料“粘附性”试验方法与沥青混合料水稳性的相关关系，并提出了评价细集料与沥青粘附性的试验方法。
South high temperature and wet climate easily leads asphalt pavement to water damage , this writer participated in the guangdong meihe highway asphalt pavement construction , mainly through the asphalt mixture marshall immersion test , splitting freeze - thaw test anylyze asphalt mixture types and asphalt content ' s influences to the water stability , and gives the linear fitting relationship about the soaking remnants stability and freeze - thaw splitting strength and oil - stone ratio . and water stable indicators and the oil - stone ratio ' s second linear fitting relationship , finally stressed asphalt and asphalt amount significance to water stability 摘要通过沥青混合料的浸水马歇尔试验、冻融劈裂试验分析了沥青类型及沥青用量对沥青混合料水稳定性的影响，并给出了浸水残留稳定度与冻融劈裂强度与油石比的线性拟合函数关系，以及水稳性指标与油石比的二次函数关系，最后指出改性沥青和沥青用量对混合料水稳定性的意义。
Emphasized on the influence of planar reflector on focusing beams , the model of immersion focusing ultrasonic field based on focusing beams reflected by planar reflector is given . and it has been studied on immersion testing the cylindrical objects with the single focus transducer , which is available for small - diameter pipelines 分析了平面反射镜对聚焦声束的影响，首次建立了超声声束经平面反射镜反射后的聚焦超声场模型；分析表明，单焦距探头经平面反射镜反射后可用于小管道的智能检测。
