摘要：In the preliminary design stage of the full form ships, in order to obtain a hull form with low resistance and maximum propulsion efficiency, an optimization design program for a full form ship with the minimum thrust deduction factor has been developed, which combined the potential flow theory and boundary layer theory with the optimization technique. In the optimization process, the Sequential Unconstrained Minimization Technique（SUMT） interior point method of Nonlinear Programming（NLP） was proposed with the minimum thrust deduction factor as the objective function. An appropriate displacement is a basic constraint condition, and the boundary layer separation is an additional one. The parameters of the hull form modification function are used as design variables. At last, the numerical optimization example for lines of after-body of 50000 DWT product oil tanker was provided, which indicated that the propulsion efficiency was improved distinctly by this optimal design method.

摘要：根据需求,仿古复制一艘20世纪20年代建造的船舶,将其停靠在码头展陈。在船舶设计过程中,考虑到该复制船的建造时间早于大部分现行规范、规则的制定时间,加之其空间狭小,为保障船上参观人员的安全性,需对其进行撤离分析。通过撤离分析,可尽早发现撤离过程中潜在的问题,从而规避风险,保障海上人命安全。该仿古复制船撤离分析工作实例可供客船设计参考。

摘要：加装风帆后船体的结构强度会发生明显变化,为更加准确地评估、校核加装风帆后船体的强度问题,选取某成品油船的货油舱段为研究对象,采用大型有限元软件ANSYS进行分析计算,参照《油船结构强度直接计算分析指南》规范进行校核,分析加帆后船体的受力特点并提出加强措施,为结构优化设计及有效控制结构重量提供可靠依据,也可为修订加装风帆船的结构强度规范提供有益的借鉴。

摘要：目的评价国内中医药治疗肺部真菌感染的随机对照试验的临床疗效。方法通过检索网上电子数据库及手工检索相关文献资料,筛选合格的临床研究,应用Jadad评分方法进行质量评价,运用异质性检验、Meta-分析、漏斗图分析方法统计相关数据。结果共检索到符合纳入标准文献7篇,纳入试验的方法质量学评估均为低质量试验。纳入研究的总有效率和治愈率分析均显示中医药治疗肺部真菌感染的疗效相对西药对照组有效。倒漏斗图形显示不对称,提示存在发表偏畸。结论中医药治疗肺部真菌感染疗效的临床疗效有待严格设计的随机、双盲、安慰剂对照试验加以证实。
