简介：在这份报纸，我们以光线参数导出SS波浪思考系数和S波浪光线橡皮阻抗(SREI)的表示的近似。SREI能被S波浪发生角度或P波浪思考角度表示，分别地叫作SREIS和SREIP。我们用从真实木头大小导出的有弹性的模型的学习证明SREIP比SREIS和常规S波浪为岩性学和液体辨别有更好的能力橡皮阻抗(SEI)。我们从Castagna和史密斯(1994)用25组样品评估SREIP可行性。每个样品组被使用页岩构造，盐水沙，并且煤气沙。理论评估也显示全体的那SREIP事件角度比常规液体指示物对液体更敏感。真实地震数据申请也显示出角度计算了高效地使用P波浪和S波浪阻抗罐头的全体的那SREIP描绘紧密煤气沙。

简介：正如读者看到的那样，这一期我们的封面是关于汽车4S店的变局。我们的结论很直接简单：4S店的4个＂S＂会被拆散，会少一个S或者少二个S。为什么呢？随着城市土地价格上涨，4S店占地面积会变得越来越小，老板们开不起综合性的4S店，就会想着瘦身，不可能再单独包含着“维修功能”，于是，一个“S”就出局了，接着，另外一个S，也出局了。我们喜欢小S，但我们会拆散“4S”。
