人力资源管理的系统观--基于管理熵、管理耗散结构角度的分析

人力资源管理是一项系统工程，熵增加原理、耗散结构理论是理解开放系统演变的一把钥匙。以此为出发点建立人力资源管理的系统观。     

Urban Integrated Transportation Planning Based on Transit Oriented Development and its Research Challenges

Satisfying the increasing traffic demand with the least amount of resource and environmental costs, the sustainable development object of urban traffic system determines that from long-term viewpoint, it is necessary to establish urban integrated traffic planning system with public transport as it is. The planning idea of Transit Oriented Development (TOD) is an important method to realize urban integrated traffic planning system. Research and practice reveal that harmony and integration is the key method to solve urban traffic problems. The integration of traffic system and land-use is the basic problem. Urban traffic development strategy with TOD provides ideas and ways to harmonize the traffic and land-use systems, which brings out a series of new research subjects and challenges in the field of traffic planning.     

公交IC卡收费系统与客流数据采集、处理

根据目前国内公交收费的发展趋势,设计出用于对客流等数据采集的IC卡自动收费系统,并提出利用它来进行客流等数据采集、处理的新方案.与人工调查相比,它的投入小得多,并且可以提供大量详细、准确的动态数据,对城市公交以及公交的智能化调度、线路的开辟、优化、站点的设置等都具有极其重要的意义.     

黄骅港外航道大风骤淤的机理及其整治

黄骅港位于渤海湾西南，是建在淤泥质海岸上的人工港，在特殊大风期间，即E向或ENE向6级以上的海向风廷时14小时以上时，外航道的淤积量大大超过原先的预测值，且淤积物为密实、坚硬、难以疏浚的粉沙。本研究表明，这一问题产生的原因是堤头旋涡的输沙作用，卫星图像和数模证明了堤头旋涡的存在；同时还对设置垂直和平行于海岸线防波堤的两种整治方案作了讨论。

机器人产业上市公司融资效率研究

当前全球科技创新竞争日趋激烈,作为高端科技引领的机器人产业已成为衡量一个国家科技水平和经济智能化程度的重要标志。技术、资金、人才、政策的投入效率均可能对该产业的发展带来深刻影响。本文以我国机器人产业上市公司为研究对象,运用DEA-Malmquist指数方法对2011—2016年间的融资效率及其动态变化情况进行实证分析。研究表明,该产业上市公司的融资效率总体上呈现动态提高趋势,在股权融资、内部融资和债务融资3种主要融资方式中,股权融资的融资效率最高,债务融资次之,内部融资最低,但不同的融资方式对融资效率的影响效应不同。     

Synthesis and luminescence properties of Mn4+-dopant Ca14Zn6Ga10−xAlxO35 solid solution

Mn~(4+)-activated oxide phosphors,owing to their desirable spectral features,eco-friendly and low cost,are emerging as a new class of non-rare-earth red phosphors for warm white LEDs.However,these phosphors possess low photoluminescence quantum efficiency excited by blue chip currently.Herein we report an isostructural solid solution of Ca_(14)Zn_6Ga_(10-x)Al_xO_(35):0.15Mn~(4+)(0≤x≤10)synthesized by a traditional solidstate reaction route.The microstructure and luminescent performance of this red-emitting phosphor are investigated in detail with the aids of X-ray diffraction,diffuse reflection spectra,photoluminescence spectra/decay/QE,and temperature-dependent PL/QE measurements.Blue shift of energy peaks of~4A_2→~4T_1and~4A_2→~4T_2transition is illustrated by the Tanabe–Sugano diagram and the configurational coordinate diagram.The crystal field strength(Dq)and the Racah parameters(B and C)are carefully calculated to estimate the nephelauxetic effectβrespectively.Particularly we achieve external and internal quantum efficiencies as high as26.1%and 40.3%for Ca_(14)Zn_6Ga_6Al_4O_(35):0.15Mn~(4+)excited by 466 nm,the highest one ever reported in Mn~(4+)activated oxide phosphors under the similar condition.     

从沸腾炉渣中浸取有价金属

研究了从钢厂炉渣中回收有用金属的一种新方法。实验中，炉渣用硫酸浸取，浸取液采用EDTA络合滴定分析元素组成，颗粒粒径分布采用标准筛筛分，化学组成和微观结构分别采用XRF。结果表明，铝的最大提取率为86．20％，条件为：H2SO4浓度4mol·L^-1、固液比1：5条件下在80℃浸取24h。在同一条件下铁获得最大提取率为94．3％。     

孔隙型碳酸盐岩储层注气注水提高采收率试验

中东地区部分碳酸盐岩储层类型以孔隙型为主,裂缝不发育,气测渗透率低,流体物性较差.以中东某油田S油藏为例,开展注气和注水可行性试验研究,并探讨其提高采收率的微观渗流机制.结果表明:受物性特征影响,储层注伴生气驱最小混相压力高,地层条件下不易达到混相驱替,但整体上岩心注烃类气驱效率要高于水驱效率,尤其当达到混相条件时,气驱效率明显提高;注烃类非混相驱油效率也相对较高,主要是由于储层原油黏度较高,气驱使原油体积膨胀,黏度降低,进而改善流动性;试验采用的水驱和气驱方式在微观上主要动用大孔隙中的可动流体,可考虑优化驱替方式进一步提高驱油效率.
