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:摘要目的探讨老年人Colle’s骨折手法复位、小夹板或石膏夹板固定,配合患肢功能锻炼的疗效。方法对150例老年人Colle’s骨折,运用手法复位、小夹板或石膏夹板固定,配合患者主动功能锻炼。结果参照1975年全国骨科会议制订的《骨折疗效标准草案》评定,150例中,优91例,占60.7%;良47例,占,31.3%;尚可10例,占,6.7%;差2例,占1.3%;优良率92.0%。结论老年人Colle’s骨折,运用手法复位、小夹板或石膏夹板固定,配合患肢功能锻炼,可取得满意的疗效。

简介:目的探讨小儿腹部Burkitt's淋巴瘤的多排螺旋CT影像特点及鉴别诊断.方法收集21例经手术及病理活检证实的小儿腹部淋巴瘤21例,其中,Burkitt's淋巴瘤12例,非Burkitt's淋巴瘤9例,分别比较两组淋巴瘤的临床症状、发病部位、肿块大小、肿块内坏死灶情况、受累肠壁厚度及扩张度、腹腔淋巴结及肝脾情况等CT影像学表现,采用统计学软件SPSS计算结果.结果Burkitt's淋巴瘤常常形成较大肿块,直径>40mm,占91.7%,最常见发生于肠管,占66.7%,受累肠管肠壁呈肿瘤样增厚,占66.7%,受累肠管常常扩张而非狭窄,占50%,肝脾肿大较少见.与非Burkitt's淋巴瘤比较,均有显著性差异(P值均<0.05).结论小儿腹部Burkitt's淋巴瘤在螺旋CT上有多个特征性影像学表现,结合病史及临床表现能够做出较明确的诊断.
