摘要：近年来我国大型风电基地建设速度放缓,超低风速型风电机组陆续推出,使得在并网条件较好的低风速地区风电开发成为热点,低风速区域大多位于我国中南和西南地区,相应的风电场大多位于山地丘陵地带,传统的重力式基础依靠增大面积提供对更大容量风机的支撑出现了瓶颈,因此引入主动土压力作为抗力,其代表为PH桩基础,引入锚杆拉力作为抗力,其代表为岩石锚杆基础。建议合理的选用相应参数和风机控制策略,对于大容量和8度地震区的风电站,逐步采用振型分解反应谱法进行设计。

摘要：目的 探讨RA患者就医行为特点以及慢病综合管理对其的干预效应.方法 对2012年8月至2013年6月在四川省人民医院风湿免疫科门诊就诊的240例RA患者进行分析.内容包括患者的一般资料、首次就诊医师类型、就诊时机、确诊科室及相关知识获取来源等,然后以配对分组方法将患者分为对照组与干预组各120例,在常规口服药物基础上,干预组给予6个月的慢病综合管理,比较2组患者依从性及疾病达标率.采用t检验,x2检验和Spearman相关分析进行统计分析.结果 患者首诊医师选择及就医时机与性别、发病年龄及文化程度无明显相关性（P＞0.05）,而首诊医师选择与个人收入（x2=59.684,P＜0.0）、有无医保（=29.202,P＜0.01）相关.确诊科室以风湿免疫科最高（88.8％,213/240）,疾病知识获取来源前2位是周围人群（35.8％,86/240）和医疗广告（28.3％,68/240）,来自医生的仅占10.0％（24/240）.在干预阶段,干预组规律服药比例更高[83.6％（92/110）与64.1％（59/92）,x2=10.100,P＜0.01],更容易达到基于DAS28计算的良好反应[67.3％（74/110）与53.3％（49/92）,x2=4.130,P＜0.05].结论 RA患者首次就诊行为受经济因素影响较大,通过慢病综合管理能规范RA患者的部分就医行为,提高患者依从性及疾病缓解率.

摘要：采用CFD技术模拟了船池试验三体船型在不同速度下的粘性流场,计算中考虑了自由表面效应影响,数值模拟结果与试验结果进行了比较,然后在此基础上计算了侧体对应于不同纵横向位置时的9种三体船方案的总阻力。分析比较各方案的计算结果后,得出三体船阻力性能较优时侧体布局的一般规律,即侧体纵向位置变化对三体船静水阻力性能影响较大,当侧体横向位置不变,在较高速度时侧体纵向向后布置对阻力性能更有利。最后按阻力性能,从9种计算方案中得出优选方案。

摘要：[Objective] To study the correlation between the biomechanical properties of rape stalks and rape stem lodging. [Method] Through axial compression tests to the stalks of 4 different rape varieties, the change rules of maximum stem bearing ca- pacity, maximum compressive strength, elastic modulus and moment of inertia along plant height were analyzed, as well as the effect of different varieties and water contents on the biomechanical property indices of rape stalks. [Result] The maximum loads of rape stalks presented liner decrease trend along with the increase of stem height, and all reached the maximums below the height of 50 cm. The maximum stem compressive strength and elastic modulus of the 4 varieties were increased with ascending height, but in a slow rate with small change, thus the modulus of e- lasticity could be considered as unchanged. The maximum bearing capacity, maxi- mum compressive strength and elastic modulus of dry rape stalks were higher than wet stalks, indicating that the water contents of rape stalks had significant effect on their mechanical properties. According to the actual lodging situations in filed, stalks of variety No. 1 owned the worst biomechanical properties and lodging degree, while the biomechanical properties of No. 6 and F5 were better than No. 1 and No. 9, and they also had stronger lodging-resistance. [Conclusion] The study provides parameters and bases for the design of mechanized production and mechanical deep processing of crops, and can better reveal the physical natures of organisms. The methods used in this study can also be used to screen excellent crop stalks.

摘要：为探索中医治未病理论和方法体系进行肛管直肠癌早期医学干预的可行性，应用自行设计的肛管直肠癌治未病技术方案，针对社区人群进行生活习惯调查、体质辨识、症候分析等治未病技术操作，结合粪便检验、肿瘤标志物检验、直肠镜检等方法，判断高危人群并进行中医医学干预。结果显示，2000名社区人群，饮食习惯不良者613人，有慢性肠道疾病史者36人；体质判定有偏颇体质者66．95％（1339例）；偏颇体质者42．49％（569）表现为湿热蕴结；全组检出直肠息肉（腺瘤）11例，直肠炎症及溃疡5例，发现早期直肠癌2例。开出治未病处方1321份，转临床治疗18例。结果表明，运用中医治未病体系，能有效地确定肛管直肠癌的高危人群，及时发现早期癌变，指导进行防病调理养生，调整偏颇体质，远离患病危险因素，遏制肛管直肠癌的进程。
