以作业的自升式风电安装船(简称风装船)为研究对象,建立力学模型并采用正交法对其因子进行试验设计,研究其工程力学参数并进行优化。研究结果表明,作业水深为重要因子,作业风向角为较重要因子,得到优化参数为:风向角为0°,入泥深度为4 m(硬质土)及9 m(软质土),气隙为10 m,桩腿横向长度为70 m。优化后风装船随时间变化的船位置点位移幅值及弱点轴向应力幅值减少,改善了力学特性。

阿拉善北部宗乃山地区出露少量前寒武纪岩石,主要为一套变质表壳岩和变质深成侵入岩组成的变质杂岩,其形成时代和同位素特征对于了解该地区的基底性质和探讨阿拉善北部构造格架具有重要意义。本文对宗乃山西南缘阿尔滕托亚副片麻岩和嘎顺呼都格正片麻岩开展了详细的岩石学、锆石U-Pb年代学和Hf同位素研究,并对其构造意义进行了初步探讨。阿尔滕托亚副片麻岩包括黑云二长片麻岩和变斑状黑云斜长片麻岩,两套岩石中分选出来的锆石具有典型岩浆锆石特征,LA-ICPMS分析结果显示这些锆石的207Pb/206Pb年龄相对集中,并分别获得了1459±11Ma(MSWD=3.3)和1458±3Ma(MSWD=0.13)的年龄。初步研究认为阿尔滕托亚副片麻岩的源区存在~1.46Ga的岩浆事件,这些副片麻岩形成时代稍晚于该期岩浆事件。嘎顺呼都格正片麻岩以角闪黑云二长片麻岩为代表,其锆石结晶年龄为1433±17Ma(MSWD=0.25)。锆石Hf同位素分析结果显示,阿尔滕托亚副片麻岩和嘎顺呼都格正片麻岩具有一致的锆石εHf(t)值(+0.1^+11.9),二阶段模式年龄为2.19~1.44Ga,反映了片麻岩原岩岩浆可能来自当时相对年轻的地壳物质。结合前人研究成果,宗乃山前寒武纪岩石可能主要形成于中元古代1.4~1.5Ga,而不是以往认为的中太古代-古元古代。截至目前,宗乃山-沙拉扎山构造带暂未发现类似阿拉善地块内部的太古代-古元古代基底岩石,因而其与阿拉善地块在早前寒武纪的亲缘性存有疑问。

目的探讨不同麻醉方式对于肝细胞癌（HCC）术后预后的影响。方法选取中国医学科学院肿瘤医院2006年1月至2008年1月行手术治疗并获完整随访的HCC患者共185例。美国麻醉医师协会分级（ASA）Ⅰ～Ⅲ级，体质指数（BMI）为（22.8±4.6） kg/m2。其中，男169例，平均年龄56岁；女16例，平均年龄53岁。根据麻醉方式不同，将185例患者分为全凭静脉麻醉组53例，吸入麻醉组132例。近期随访对比术后疼痛及麻醉不良反应发生率，疼痛评分采用数字分级法（NRS），远期随访对比两组患者预后情况。结果全凭静脉麻醉组术后2 h NRS为2.0（0～2.0）分，疼痛程度明显低于吸入麻醉组的3.0（1.0～3.0）分，差异有统计学意义（Z＝－3.261，P＝0.001），而两组术后24 h的NRS分别为3.0（2.0～5.0）分和3.0（3.0～4.0）分，疼痛程度差异无统计学意义（Z＝－0.035，P＝0.972）。两组在术后镇静、恶心呕吐、躁动等不良反应发生率方面差异亦无统计学意义（均P〉0.05）。Kaplan－Meier单因素分析显示，两种麻醉方式对于无复发生存率及总生存率差异均无统计学意义（均P〉0.05）。Cox多因素分析亦显示两种麻醉方式不是影响HCC预后的独立影响因素。结论不同麻醉方式对于HCC长期预后无影响。

用相似材料制作含预制裂隙岩体无锚和加锚试样,以锚杆与裂隙呈45°、90°打入锚杆制作3组试样,进行60次冻融循环,对冻融过程中裂隙进行应变监测并对冻融循环60次后的试样进行单轴压缩试验,探讨冻融循环作用下不同角度的锚杆支护对裂隙岩体的裂隙扩展规律、锚固效应及破坏模式的影响。研究结果表明:裂隙岩体在经历30次冻融循环之前,两种支护方式对裂隙的控制效果相当,随着冻融循环的进行,锚杆支护角度会对作用于锚杆的摩阻力产生一定影响,锚杆与裂隙夹角越大,作用于裂隙的摩阻力越大;天然状况下一个冻融循环周期内裂隙的应变大致经历了冷缩→冻胀→冻胀稳定→融缩→回弹→稳定6个阶段,两种支护工况均未出现明显的融缩阶段和回弹阶段,且90°支护工况效果比45°支护工况效果更加明显;对裂隙岩体采用水泥浆进行压力灌浆,由于水泥浆的保护作用可以对整个锚固系统起到一定的修复作用;锚杆增强了裂隙岩体抵制裂隙扩展的能力,降低了裂隙岩体劈裂破坏的突然性,且破坏模式由张拉破坏转换为张剪复合破坏。
