Prediction and setup of phytoplankton statistical model of Qiandaohu Lake

This research considers the mathematical relationship between concentration of Chla and seven environmental factors, i.e. Lake water temperature (T), Secci-depth (SD), pH, DO, CODMn, Total Nitrogen (TN), Total Phosphorus (TP). Stepwise linear regression of 1997 to 1999 monitoring data at each sampling point of Qiandaohu Lake yielded the multivariate regression models presented in this paper. The concentration of Chla as simulation for the year 2000 by the regression model was similar to the observed value. The suggested mathematical relationship could be used to predict changes in the lakewater environment at any point in time. The results showed that SD, TP and pH were the most significant factors affecting Chla concentration.     

Study of CNG／diesel dual fuel engine＇s emissions by means of RBF neural network

Great efforts have been made to resolve the serious environmental pollution and inevitable declining of energy resources. A review of Chinese fuel reserves and engine technology showed that compressed natural gas (CNG)/diesel dual fuel engine (DFE) was one of the best solutions for the above problems at present. In order to study and improve the emission performance of CNG/diesel DFE, an emission model for DFE based on radial basis function (RBF) neural network was developed which was a black-box input-output training data model not require priori knowledge. The RBF centers and the connected weights could be selected automatically according to the distribution of the training data in input-output space and the given approximating error. Studies showed that the predicted results accorded well with the experimental data over a large range of operating conditions from low load to high load. The developed emissions model based on the RBF neural network could be used to successfully predict and optimize the emissions performance of DFE. And the effect of the DFE main performance parameters, such as rotation speed, load, pilot quantity and injection timing, were also predicted by means of this model. In resum6, an emission prediction model for CNG/diesel DFE based on RBF neural network was built for analyzing the effect of the main performance parameters on the CO, NOx emissions of DFE. The predicted results agreed quite well with the traditional emissions model, which indicated that the model had certain application value, although it still has some limitations, because of its high dependence on the quantity of the experimental sample data.     

经济全球化形势下企业的环境责任审计

阐述了经济全球化形势下对企业进行环境责任审计的必要性。指出了企业环境责任审计的具体内容,注重企业投资的可行性,对企业环境责任进行事前审计;评审企业环境成本和环境效益,对其环境责任进行事中审计;为使企业树立环保形象,对企业环境责任进行事后审计。认为作好企业环境责任审计工作,应从财务审计入手,评审其环保成本和环境效益;抓好重点行业、重点企业的环境责任审计;抓好乡镇企业的环境责任审计;加快制定环境责任审计的规范和评价标准;加强环境责任审计人员的培养。     

环境化学污染物与人类健康

中国是经济发展最快的发展中国家之一，一方面快速发展的经济使人民生活不断提高，另一方面环境污染、尤其是环境化学物的严重污染对人体健康带来多种危害，包括呼吸系统疾病、神经系统疾病、肿瘤、出生缺陷等，甚至死亡。毋庸置疑，严重的环境污染可导致受害的众多民众失去健康和劳动能力，甚至丧失生命，是重大的社会问题乃至国际化问题，如著名的英国伦敦烟雾事件、美国洛杉矶汽车尾气事件以及日本新泻的水俣病．
