科尔沁沙地道路风沙灾害危险性评价的指标体系

, 2009
构建沙区道路风沙灾害危险性评价的指标体系对区域道路风沙灾害防治重点区的划定及减灾对策的制定有着重要意义。文中以区域灾害系统理论为依据,通过分析灾害形成过程中致灾因子、孕灾环境、承灾体三者的作用机制,提出孕灾环境对灾害形成存在直接和间接两种作用的思想;在分析道路风沙灾害形成机制的基础之上,建立了科尔沁沙地道路风沙灾害危险性评价的指标体系并进行评价。结果表明:轻度危险路段417km,中偏轻度危险路段657km,中度危险路段798km,中偏重度危险路段453km,重度危险路段150km ...

原发性肝癌根治术后复发的相关危险因素分析

, 2008
【目的】 探讨原发性肝癌(以下简称肝癌)根治术后复发的相关危险因素。 【方法】 回顾性分析210例根治性切除肝癌患者的临床病理资料,采用Cox模型分析早?晚期复发病例临床病理因素与复发的关系。【结果】 126例患者出现复发(复发率60%),早期复发89例,占70.6%,以Ⅱ型为主,单因素分析显示瘤体直径?血管侵犯?手术切缘?微转移灶和肿瘤分化程度与术后早期复发相关,血管侵犯?微转移灶和病理分级是术后早期复发的独立危险因素;晚期复发37例,占29.4%,以Ⅰ型为主 ...
