With incessant development of Chinese real estate market, the amount and size of real estate corporations are enlarging rapidly and the real estate corporation investment goal is tending to become divertive. So it is especially important to understand rightly the investment goal of the real estate corporations. This paper analyzes the unbalance phenomena of real estate corporation investment under the environment of high profit margin and discusses the serious aftereffect from this unbalance. Finally this paper brings forward the right order of investment goals for the real estate corporations in order to contribute to a nicer performance of real estate corporations in establishing sustainable development stratagem. 相似文献

The Sijiaotian Tunnel in Yunnan Dabao Highway lies in the narrow defile landscape,and the engineering geology condition is complex,with plenty of cienega.According to the actual situation of the Sijiaotian Tunnel Project in Yunnan Dabao Highway,the stability of the surrounding rock mass is studied by using a 3-D non-linear FEM.The Drucker-Prager criterion is chosen as the failure criterion of the rock.The relatively dangerous zone and the monitoring points in the tunnel are determined.The numerical results show that the Sijiaotian Tunnel is relatively stable.The conclusion has some significance for guiding the construction of similar projects. 相似文献

各省、自治区、直辖市人民政府,国务院各部委、各直属机构:《中华人民共和国种子法》实施五年多来,我国农作物种子(以下简称种子)产业发生了重大变化,种子市场主体呈现多元化,农作物品种更新速度加快,有力地推动了农业发展和农民增收。但是,由于我国种子产业仍处在起步阶段,种子管理存在体制不顺、队伍不稳、手段缺乏、监管不力等问题,一些地区种子市场秩序比较混乱,假劣种子坑农害农事件时有发生,损害了农民利益,影响了农业生产安全和农民增收。因此,改革和完善种子管理体制,加强种子市场监管,对于提高农业综合生产能力,确保国家粮食安全,促进农民增收,具有十分重要的意义。 相似文献

The Extended Kalman Filter Data Fusion Algorithm Based on Discrete Stationary Wavelet Transformation
It is difficult to establish precise mathematical model in extended Kalman filter data fusion algorithm for GPS/ DR integrated vehicle navigation system, an improved extended Kalman filter data fusion algorithm is put forward based on Discrete stationary wavelet transformation. The simulation results show that the algorithm is better than the extended Kalman filter data fusion algorithm, and is available for GPS/DR integrated vehicle navigation system. 相似文献

In this paper, the cause analysis about cracks on the new concrete web poured in multi -span continuous box -girder of a main bridge was introduced. This bridge is a prestressed concrete one with variable cross sections and an 80 -meter main span. When casting reinforced concrete in large volume in box girder during vehicle transport service, the shrinkage cracks in cast -in place reinforced web concrete were formed due to the restriction of old web concrete. Then, the control measure taken on these cracks is discussed. 相似文献

ANSYS has become an effective tool for finite element analysis of masonry structure, but there is few common conclusions for reference. According to the characteristics of ANSYS and the essence of the analysis, some key problems in finite element analysis of masonry structure with ANSYS, such as structural modelling, material constitution, the damage criterion, iterative algorithm, convergence criterion, simulation of prestressing force and so on, are discussed in this paper. Based on the test results of typical masonry structures, the applicability of ANSYS to masonry structural analysis is studied and some suggestions for the application of ANSYS are presented. 相似文献
