Abstract: 现阶段,企业与企业之间的竞争已经逐步转变为供应链与供应链之间的竞争,加强供应链管理已经逐渐成为企业获取竞争优势的重要策略,而促进供应链成员间的整合则是供应链管理成功的关键。基于以往的供应链整合研究,文章从供应链整合的两个维度——跨度与强度——出发,分别探讨供应链整合在两个维度上的演进机理,并指出供应链整合是供应链成员依赖于关系学习的两个维度相互作用、互动演进的有限过程,为供应链整合提供了新的理解角度,并辅以永辉超市供应链整合的案例加以验证。
At present, the competition between enterprises and enterprises has been gradually transformed into competition between supply chain and supply chain, supply chain management has gradually become the important strategy of enterprises to obtain competitive advantage while promoting the integration between the supply chain members is the key to the success of supply chain management. Based on researches about supply chain integration, the article discusses the evolution of supply chain integration from two dimensions:strength and span. Then, the article points out that the behavior of supply chain members depends on relationship learning in the process of supply chain integration. This article provides a new angle to understand the supply chain integration. What's more, the article uses the case of Yonghui to supplement the theory.

Abstract: 导热系数是建筑材料最重要的热湿物性参数之一,温度和含湿量均能够对其产生影响。当温度和含湿量中的一个因素被确定后,一元线性函数通常被用来描述另一个因素对导热系数的影响。然而,实际情况下二者对导热系数的影响是同时存在的。采用防护热板法对聚苯乙烯泡沫(EPS)、岩棉、混凝土、胶粘剂和抹面胶等5种典型建筑材料在不同温度和含湿量下的导热系数进行测试。结果表明,对上述材料而言,二元线性函数可以用来描述温度和含湿量对导热系数的影响,且温度和含湿量之间的交互作用可以被忽略。对于EPS和岩棉等弱吸湿弱毛细材料而言,可以将二元线性函数简化为仅与温度相关的一元线性函数。
Thermal conductivity is one of the most important hygrothermal properties of building materials which depends on temperature and moisture content. The one-variable linear function is usually used to describe the influence of either temperature or moisture content on the thermal conductivity when the other one is fixed. However, for real situations temperature and moisture content have simultaneous influence. The thermal conductivities of five typical building materials-expanded polystyrene (EPS), mineral wool, concrete, adhesive mortar and rendering plaster-were measured with the guarded-hot-plate apparatus at different temperature and moisture content. Results show that the two-variable linear function is sufficient to describe the coupled influence of temperature and moisture content on all studied materials. The interaction between temperature and moisture content is negligible. For weakly hygroscopic and capillary materials such as EPS and mineral wool, the two-variable linear function can be simplified to the one-variable linear function of temperature.

Abstract: 全面深化司法改革的核心是还权于司法者,其必然导致司法权力运行主体更加分散化、内部行政监督更加弱化。在此新形势下,加强和完善各级人大及其常委会的司法监督正当其时。人大监督司法是对行使审判权和检察权的主体即法院和检察院的监督,其根本内容不是监督司法行为或司法活动,而是监督司法权。监督司法工作的具体内容应当类型化为法律监督、工作监督和人事监督三个方面,并且实现法律监督的深入化、工作监督的常态化和人事监督的实质化,才能有效提升各级人大及其常委会的监督质效,确保宪法赋予的监督权得到正确、有力的实施。
The core spirit of the deepening of judicial reform comprehensively is to return the original power to the judges and prosecutors. Therefore, the judicial power operating subject will be more decentralized, and the inner supervision will be more weaken. In this situation, it is the right time to strengthen and improve the judicial supervision of all levels of People’s Congress and its standing committee. The judicial supervision of the People’s Congress is to supervise the people’s courts and procuratorates. The principal contents of the supervision is to supervise the power of judicial power, not the judicial acts. The judicial supervision should be typed as legal-supervision, work-supervision and personnel-supervision. In order to effectively improve the supervision quality and efficiency of the people’s congresses at all levels and the Standing Committee, to ensure the constitutional power be implemented correctly and completely, the legal-supervision should be deepen, the work-supervision should be normalized, and the personnel supervision should be substantialized.

Abstract: 保温措施是既有建筑节能改造中最有效的节能措施之一。在墙体节能改造设计中,保温材料种类及其厚度的确定是至关重要的,受到多个目标参数的制约和影响。基于反问题的研究方法,建立数值计算方法与多目标遗传算法NSGA-Ⅱ相结合的优化模型,以单位面积墙体全年总能耗和保温材料成本为目标参数,对成都地区某既有建筑墙体节能改造的保温材料种类与厚度进行了协同设计。结果表明,采用常规的保温厚度,常用的8种保温材料中有6种都不是最优解,但是可以通过改变保温材料的厚度或单价等方法使解向Pareto前沿逼近,以实现单位面积墙体年总能耗最小和改造成本最小之间的平衡。
Insulation is one of the most effective measures in energy-saving renovation of existing buildings. The determination of type and thickness for the insulation material is crucial in the energy-saving design of wall, which is determined by multiple target parameters. An optimization model combined the numerical method with multi-objective genetic algorithm (NSGA-Ⅱ) is established based on the inverse problem research method. The total energy consumption of the unit area wall and the transformation cost are selected as the objective parameters, and the synergic design for type and thickness of the insulation material is made for the existing building wall renovation in Chengdu. The results show that there are 6 of the 8 kinds of insulation materials are not the optimal solutions with the conventional thickness. However, the solutions can approach the Pareto frontier by changing the thickness or unit price of the insulation materials, and a balance can be realized between the minimum annual energy consumption and reconstruction cost. The method proposed offers a new idea for building energy-saving design. The conclusions can provide references for the similar energy-saving renovation in Chengdu.

Abstract: 将消能减震概念应用于非结构构件,提出一种屈服耗能隔墙。该隔墙在小震下为主体结构提供可量化的刚度支持,大震时提供可调节的耗能能力支持。通过对屈服耗能隔墙试件进行不同耗能元件数量下的静力往复试验,研究了该类型隔墙的消能机理与破坏模式,并基于IDARC程序中的柱单元对试件进行模拟,获得了消能元件数量与隔墙滞回参数之间的量化关系,提出了在IDARC程序中模拟设置屈服耗能隔墙的方法。通过对一个6层钢筋混凝土框架进行不同屈服耗能隔墙设置方案下的动力时程分析,发现屈服耗能隔墙的设置能够有效减小结构的地震反应、降低结构的损伤;框架中耗能隔墙数量的增加会使结构的层间位移显著减小,而隔墙数量相同时,隔墙中耗能元件数量的增加并不会导致结构层间位移发生明显变化。
By applying the ideal of energy dissipater to nonstructural components, yielding energy dissipation partition (YEDP) was proposed. The YEDP could provide quantifiable stiffness under minor earthquakes and adjustable energy dissipation capacity under major earthquakes. The static cyclic loading tests of YEDP with different number of energy components were completed, and the energy dissipation mechanism and failure mode of YEDP were got understanding. Based on the quantitative relationship between number of energy components and hysteresis curve parameters, the method which using column unit of IDARC program to simulate YEDP was proposed. The dynamic time-history analysis of 6-storey reinforced concrete frame under different YEDP set programs were carried out, the results show that YEDP could effectively reduce the seismic response of the structure. The interlayer displacement of structure decreases significantly with the increasing of number of YEDP, but be changeless with the increasing of number of energy components in the YEDP when the number of YEDP is same.

Abstract: 为研究有压水环境中循环荷载历史对混凝土动态力学性能的影响,对历经不同荷载循环次数(0、25、50、100次)的水饱和混凝土试件(在2 MPa围压水环境中)进行了不同应变速率(10-5、10-4、10-3、10-2/s)下的常规三轴静动态压缩试验,分析了混凝土材料的峰值应力、峰值应变、弹性模量、吸能能力等基本力学参数的变化规律和机理。结果表明:同一加载速率下,水饱和混凝土的峰值应力、弹性模量和吸能能力均随循环次数的增长呈现出先增大后减小的规律,并且峰值应力和吸能能力增减的转折点随着应变速率的提高而向荷载循环次数增大的方向平移,峰值应变整体上呈减小的趋势;相同荷载循环次数后,峰值应力、峰值应变和吸能能力随着加载速率的增大而逐渐增大,并且荷载循环次数越大,率效应越显著,弹性模量随着加载速率的增大而逐渐较小。
To investigate the influences of cyclic loading history to rate effect of water-saturated concrete under pressurized water environment, the conventional triaxial compression test was carried out in different strain rates(10-5/s、10-4/s、10-3/s、10-2/s)with the water-saturated concrete samples(in the water environment with 2MPa confining pressure)which had experienced different cyclic loading times(0、25、50、100 times), the change law and mechanism of the basic mechanical parameters such as peak stress, peak strain, elasticity modulus and energy absorption ability were analyzed. It was found that the peak stress, elasticity modulus and energy absorption ability of water-saturated concrete samples all increaseed at first and then decreaseed with the increasing times of cyclic loading, and the turning point of peak stress and energy absorption ability came close to the direction that cyclic loading times became bigger with strain rate increasing, but the peak strain decreased generally. The peak stress, elasticity modulus and energy absorption ability of the concrete samples which experienced same cyclic loading times all increased with the strain rates increasing and the rate effect was more conspicuous with cyclic loading times increasing, the elasticity modulus showed the change law on the contrary.
