用地质学的观点探讨洞庭湖的治理

洞庭湖是一断陷盆地，至今仍在继续下沉，因围湖筑垸使水面减小，泥砂堆积速度大于湖区下沉速度使湖面进一步缩小，致使洪水季节常泛滥成灾。按地质规律科学治理方案，一是退垸还湖，二是垸湖置换，才能从根本上消除洞庭湖的水灾。

A modal pushover analysis procedure to estimate seismic demands for unsymmetric‐plan buildings

An Erratum has been published for this article in Earthquake Engng. Struct. Dyn. 2004; 33:1429. Based on structural dynamics theory, the modal pushover analysis (MPA) procedure retains the conceptual simplicity of current procedures with invariant force distribution, now common in structural engineering practice. The MPA procedure for estimating seismic demands is extended to unsymmetric‐plan buildings. In the MPA procedure, the seismic demand due to individual terms in the modal expansion of the effective earthquake forces is determined by non‐linear static analysis using the inertia force distribution for each mode, which for unsymmetric buildings includes two lateral forces and torque at each floor level. These ‘modal’ demands due to the first few terms of the modal expansion are then combined by the CQC rule to obtain an estimate of the total seismic demand for inelastic systems. When applied to elastic systems, the MPA procedure is equivalent to standard response spectrum analysis (RSA). The MPA estimates of seismic demand for torsionally‐stiff and torsionally‐flexible unsymmetric systems are shown to be similarly accurate as they are for the symmetric building; however, the results deteriorate for a torsionally‐similarly‐stiff unsymmetric‐plan system and the ground motion considered because (a) elastic modes are strongly coupled, and (b) roof displacement is underestimated by the CQC modal combination rule (which would also limit accuracy of RSA for linearly elastic systems).

Integrating Environmental Education Into Business Schools' Educational Plans in Finland

Environmental education in business school context has a significant effect on the way companies view environmental problems. Business schools train the future decision makers who can, with their own attitudes and practical actions, influence the contribution of business to the process of ecologically sustainable development. However, several studies show that no systematic thinking has been undertaken within business education as to what the educational prerequisites of the process of ecologically sustainable development are. In this article, I will firstly analyze by means of environmental education how business polytechnics in Finland have taken into consideration ecologically sustainable development. Secondly, I will raise the starting points for the development of the implementation of environmental education as part of the business schools▪ educational plans. Integrating environmental education into the vocational courses is identified as being one of the most effective ways of increasing the effectiveness of environmental education. Thirdly, the emphasis is on identification of barriers of integrating environmental education into the educational plans of business polytechnics. Theoretically, the article is attached to the objectives and learning concepts of environmental education and to educational planning theory in general. The empirical data are based on interviews I conducted 1999–2000 in all Finnish polytechnics offering business education. My article increases theoretical and practical understanding of how environmental education should be implemented in business education and how the current situation could be developed. This revised version was published online in August 2006 with corrections to the Cover Date.     

基于CityEngine的三维城市规划设计与研究
