文化信念的界定及特点

文化信念是生活于特定文化环境中人们的思想，行为的原则，方式、惯性，一切信念本质上都是文化信念，改革开放以来文化的繁荣也带来了多元的文化信念，导致了社会心理层面巨大的矛盾冲突，研究文化信念为解决这一社会心理层面的矛盾冲突提供了一种可能的途径。     

白细胞透析液对山羊外周血白细胞的影响

应用山羊免疫脾细胞透析液，普通脾细胞透析液及生理盐水，分别注射３组健康同种山羊。实验前、后经颈静脉采血，对３组动物外周血白细胞计数及分类计数。发现免疫脾细胞和非免疫脾细胞透析液均能显著提高山羊外周血白细胞总数（Ｐ＜０．０１）：对白细胞分类计数的比例无明显影响（Ｐ＞０．０５）；免疫和非免疫脾细胞透析液在提高山羊外周血白细胞总数方面无显著差异（Ｐ＞０．０５）。

构建铁路客运专线综合维修管理体系研究

铁路客运专线综合维修管理模式应充分考虑我国国情，建立高效率、低成本、少用人、现代化、信息化、先进适用的综合维修管理模式，按设备的状态进行必要的“状态修”，做到既不失修，也不过剩修，避免养护维修的盲目性，使设备始终处于可靠、受控的状态。     

发动机冷却系统节能优化设计

传统发动机冷却系统的设计主要从满足散热量出发进行设计,对耗功大小的要求较低,没有量化的指标来指导冷却系统的耗功优化设计,随着全球能源危机的到来,节能成了汽车发动机设计的主要目标之一,在发动机的设计过程,冷却系统是重要构成部分,冷却系统的功耗减少可以减少发动机消耗在其附属零部件上的功率,从而提高发动机的输出功率,减少油耗。本文对传统冷却系设计存在的耗功考虑不足进行分析,提出解决方案,并确立冷却系设计用耗功评价指标,用来对冷却系统关键参数及零部件进行优化设计与匹配。     

海运温室气体减排市场机制对班轮经营的影响

班轮运输中船舶航速快,燃油消耗费用在成本中占比高.因此,与燃油消耗量密切相关的“海运温室气体减排市场机制”的实施将使班轮运输受到的影响较其他运输方式大.为研究减排市场机制对班轮经营的影响,比较了目前在国际海事组织讨论的三类主要市场机制的运行特征,分析了它们对海运运输成本的影响途径以及因实施海运排放交易体系(METS)和国际海运温室气体基金机制(GHG FUND)而产生的碳成本.在此基础上,定量分析了集装箱班轮航线经营中不同船型、航速情景下,实施市场机制产生的碳成本随燃油价格和碳价格变化的规律.结果表明,在班轮航线上,为降低温室气体排放而降低航速,尽管使投入船舶增多,但整体营运效益得到改善.高速、大型船舶减速后带来的成本降低效应比小型、低速船舶来得大.     

基于边界元和爆震分析韩国天安舰水下爆炸事件(英文)

On March 26,2010 an underwater explosion(UWE)led to the sinking of the ROKS Cheonan.The official Multinational Civilian-Military Joint Investigation Group(MCMJIG)report concluded that the cause of the underwater explosion was a 250 kg net explosive weight(NEW)detonation at a depth of 6 9 m from a DPRK"CHT-02D"torpedo.Kim and Gitterman(2012a)determined the NEW and seismic magnitude as 136 kg at a depth of approximately 8m and 2.04,respectively using basic hydrodynamics based on theoretical and experimental methods as well as spectral analysis and seismic methods.The purpose of this study was to clarify the cause of the UWE via more detailed methods using bubble dynamics and simulation of propellers as well as forensic seismology.Regarding the observed bubble pulse period of 0.990 s,0.976 s and 1.030 s were found in case of a 136NEW at a detonation depth of 8 m using the boundary element method(BEM)and 3D bubble shape simulations derived for a 136kg NEW detonation at a depth of 8 m approximately 5 m portside from the hull centerline.Here we show through analytical equations,models and 3D bubble shape simulations that the most probable cause of this underwater explosion was a 136 kg NEW detonation at a depth of 8m attributable to a ROK littoral"land control"mine(LCM).

Sensitivity analysis of thermal properties on numerical simulation results of quenching process

A three-factor three-level orthogonal test project has been designed based on the numerical simulation of a Jominy quenching process. Then the data scattering effects of thermal conductivity and enthalpy of tested steel, as well as the heat exchange coefficients of the cooling media, on the results have been studied. The results can be used as a reference for choosing the input thermal parameter in finite element simulation of quenching, and for evaluating the simulation results.
