简介：一个速度模型是影响microseismic事件地点的一个重要因素。我们为为异乎寻常的油和煤气的水库在探索定位microseismic事件考察当模特儿的速度和倒置技术。我们首先描述与在异质，anisotropy，和可变性的水力的断裂有关的水库形成的地质、地球物理的特征，然后在决定microseismic事件地点在精确性上讨论速度评价，anisotropy模型，和他们的微速摄影的变化的影响，然后为在定位事件地点造速度模型调查一些典型方法。我们断定水库的三个纠缠的物理属性使监视的microseismic很挑战性。在速度的无常当模特儿，在水力的断裂忽略它的anisotropies和它的变化能引起在监视的microseismic不能接受的microseismic事件的系统的错误地点。那么，我们为造精确速度模型建议一些潜在的方法。

简介：运用推拿手法治疗婴幼儿肌性抖颈33例，并观察治疗前后患侧胸锁乳突肌包块的B超影像的变化。结果痊愈27例，有效5例，无效1例，总有效率97．0％；B超影像显示，患侧颈部可探及梭型或卵圆形包块．呈低回声者28例，中等回声者2例，高回声者3例。治疗前后包块的长度、厚度和宽度均有明显差异，P<0．017表明推拿治疗小儿肌性斜颈疗效著；超声检查可作为推拿治疗过程中评价治疗效果的一种客观标准，是一种简捷、方便、又经济的检查方法，有利于一临床推广。
