The Analysis For Format choice of Commercial real estate project A

近年来，在住宅地产调控的前提下，商业地产作为一种高投入、高产出、不受限购约束的房地产模式，受到较大的关注。商业地产靠商圈聚集效应体现价值，为业主、商家、消费者等利益相关者带来利益。商业地产的业态形式主要包括购物中心、百货、超市、商业街、主题商场、专业市场、写字楼、酒店、影院等。中A项目是X公司以较低的土地出让价格购入的地产项目，因该项目优异的地理位置以及所在区域政策导向的改变，X公司计划把该项目打造成为多种业态的商业地产项目。本文以A商业地产项目的业态选择为对象，通过详细的市场调查以及SWOT分析、市机场机会分析等得出A项目可选择商业、酒店、公寓三种业态，并得出了三种业态的面积配比。接着，采用...In recent years, under the premise of real estate regulation, commercial real estate is given considerable attention as a high input, high output and unrestricted purchase of real estate categories.

Comprehensive research on character of collapse and fracture of thick and large overburden rock in cave mining

大红山铁矿采用无底柱分段崩落法开采,形成了规模巨大的采动区域,上覆岩层厚度达627~750 m。为了掌握上覆岩层中崩落、开裂与高应力集中区的范围及发展趋势,防止突发性的大规模动力地压灾害的发生,矿山采取多通道微震监测技术、巷道观测和钻孔探测相结合的方法,对上覆岩层进行全面监测和研究。通过多通道微震监测技术对上覆岩体中高应力集中区破裂源进行高精度定位,确定高应力集中区及其变化过程,并据此推断开裂带的外边界;同时基于双力偶点源理论,分析得到震源破裂类型为以体积增加的张拉型为主、压剪切破坏与混合破坏为辅。在专门的巷道中,通过人工直接观察,确定崩落边界、开裂带的内、外边界;地表深钻孔探测作为辅助性手段,用来确定(验证)开裂带的外边界。将这3种技术手段结合起来对2011~2013年间上覆岩层不同时期的崩落带、开裂带与高应力集中区进行综合监测,得到不同时期高应力区、开裂带和崩落带的发展过程。研究表明,上覆岩层中崩落与开裂发展过程是一个缓慢渐进的过程,不会产生大规模的突变型崩塌冲击地压灾害。本文研究成果对矿山的安全生产具有重要的指导作用。A bulky mining-out area was formed at Dahongshan iron mine with sublevel caving method. The thickness of overburden is 627 to 750 meter. In order to understand the development of collapse area,fractured zone and high stress concentration zone in overburden so as to prevent the sudden large-scale and dynamic ground pressure disasters,micro-seismic monitoring,tunnel observation and borehole detection methods were used to carry out the comprehensive monitoring and research. Base on the precise location of fracture source with multi-channel micro-seismic monitoring technology,high-stress concentration zone and its developing trend were determined,and then the outer boundary was deduced. At same time,the analysis on fracture types of fracture source with double couples model showed that the tension fracture with volume-increasing accounted for majority of all sources,while the shear failure and mixed failure accounted for minority. The boundary of collapse area,external and internal boundaries of fractured area were determined directly through the artificial observation in special tunnels. The borehole detection as the auxiliary method was used to determine and validate the external boundary of fractured zone. A comprehensive monitoring and analysis were carried out to obtain the caving zone,cracking zone and high stress concentration area in overburden in different periods from 2011 to 2013. The development of high stress zone,cracking zone and caving zone in different periods were also obtained. The studies showed that the caving and cracking processes in overburden were slow and gradual. The sudden and dynamic large-scale collapse disaster would not occur. The conclusion of this paper played an important role in guiding the safe production of the mine.国家科技支撑计划项目(2013BAB02B06);; 国家科技部科研院所技术开发研究专项资金项目(2013EG21024)~

生态流域治理的居民支付意愿研究

以基于条件价值评估法(CVM)的1063份有效问卷为基础,研究了厦门市居民对九龙江生态治理的支付意愿及其影响因素。采用Spike模型,将拒绝支付者区分为真实零支付群体和抗议性群体,并在剔除抗议性群体后,利用剩下样本对支付意愿进行了Probit回归。估算了厦门市居民支付意愿的平均金额。结果表明:剔除抗议性群体对支付意愿的研究至关重要;厦门市户籍、受教育程度较高、个人年收入较高和环境认知度较高的居民,支付意愿较高;厦门市居民对九龙江生态治理支付意愿至少为每人每年50. 19元。要加强生态环境教育;改革流域生态补偿机制;改革九龙江流域水管制体制,探索建立私有产权体制;建立完善流域环境保护的法规以及标准体系;进一步落实流域保护的目标考核责任制。国家社会科学基金规划项目“中国绿色增长方式下大气污染治理的动力机制研究”(13BJL092);;福建省软科学项目“福建省‘生态美、百姓富’的生态实现模式及途径研究”(2016R0087

MODELING of LOOP REACTOR FOR POLYPROPYLENE SPHERIPOL TECHNOLOGY

在ASPEn POlyMErS PluS软件平台上模拟SPHErIPOl聚丙烯工艺中核心液相环管反应器,采用了等效的全混流反应器模型和组合式环管反应器模型,结合工厂现场采集的数据,拟合了丙烯聚合反应动力学模型,并将该模型用于2种环管反应器模拟方法的比较。采用组合式环管反应器模型考察了丙烯聚合反应循环比对反应器撤热、聚丙烯产量和相对分子质量分布、反应器内氢气浓度分布的影响。结果表明,在高循环比操作条件下和误差允许范围内,环管反应器可以等效为一个全混流反应器。当控制环管反应器夹套冷却水出口温度不变时,过低的循环比使得反应器内的温度分布不均匀,而过高的循环比则使环管反应器的撤热能力下降;当循环比增加时,环管反应器内的温度和组分浓度梯度减小,停留时间分布均匀,趋于全混流状态,催化剂活性得到充分发挥,聚丙烯产量也相应增加。Both the continuous stirred tank reactor model and the combined tubular loop reactor model were set up to simulate the steady-state performance of the industrial tubular loop reactor of Spheripol technology of propylene polymerization based on the Aspen Polymers Plus software.A comprehensive catalyzed polymerization kinetic model was verified by using plant data,and was employed to analyze the operational performance of the two models.It was observed that in high recycle ratio for propylene polymerization,the tubular loop reactor could be simulated,to a certain error degree,by a continuous stirred reactor.In addition,the effects of recycle ratio on the performance of the loop reactor could also be obtained via the combined model.The simulated results showed that the low recycle ratio made the temperature change along the tubular loop reactor in a large range under the constant coolant outlet temperature,while the high recycle ratio made the reaction temperature uniform in the tubular loop reactor,but the capacity of heat evacuation reduced.On the other hand,with the increase of recycle ratio,the concentration gradients of reaction components were lowered,and the polypropylene production was enlarged,approaching to the performance of the continuous stirred reactor.中国石油天然气股份有限公司兰州石油化工研究中心项目(2008015)资

In situ Time-resolved FTIR and Raman Characterizations of the Partial Oxidation of Methane to Synthesis Gas over Ir/SiO_2 Catalyst

[中文文摘]采用原位时间分辨红外光谱和原位显微Raman光谱技术对Ir/SiO2 上甲烷部分氧化 (POM)制合成气反应的初级产物和反应条件下催化剂表面物种进行了跟踪考察 ,实验结果表明 ,在H2 预还原的新鲜Ir/SiO2 表面 ,CO是V(CH4)∶V(O2 )∶V(Ar) =2∶1∶45混合气反应的初级产物 ,因而甲烷的直接氧化过程是CO生成的主要途径 ;而在稳态反应条件下 ,CO生成的途径可能主要来自CO2 和H2 O与催化剂表面积碳物种 (CHx)和 /或CH4的反应 .催化剂上生成的积碳可能是导致稳态条件下Ir/SiO2 上POM反应机理不同于H2 预还原的新鲜催化剂的主要原因。[英文文摘]In situ time-resolved FTIR and in situ microprobe Raman spectroscopies were used to follow the primary products as well as the surface and gas phase species formed during the reaction of partial oxidation of methane (POM) to synthesis gas over Ir/SiO 2 catalyst. The results suggested that direct oxidation of CH 4 to CO is the dominant pathway of POM reaction over the freshly reduced Ir/SiO 2 catalyst, while the dominant schemes of CO formation over the catalyst under the steady state reaction condition are probably via the reactions of CO2 and H2O with the deposited carbon species (CHx) and/ or CH4 . The mechanistic difference between the POMto synthesis gas over freshly reduced Ir/ SiO2 catalyst and the catalyst under the steady state reaction may have resulted from the formation of significant amount of deposited carbon species in the latter system.国家重点基础研究发展规划 (No.G1999022408); 国家自然科学基金(No.20021002)资助项目
