A regional environmental management information system for Chinese EPA—the system analysis and design

REMIS is one of key research projects sponsored by the central government. It is recommended to regional EPAs as a main tool of the environmental management. REMIS simulates the functions of the regional EPAs and aimed to improve their management level. The national environmental management information system will base on REMIS.Functional analysis is the kernel of the REMIS system analysis. Data and data flow analysis are used to support the functional analysis.Investigations on the functions of the local EPAs of eight provinces and 12 cities have been taken. The functions were carefully sorted. Modular design method was used in system analysis and system design.The system analysis included functional analysis, data analysis and data flow analysis. The system design is based on the system analysis. HIPO diagram of each modular, data base structure, menu design, selection of hardware and software environment were the main items of the system design.

烃类化合物气相色谱保留指数与其分配系数关系研究

报道了从烃类化合物气相色谱保留指数预测其正辛醇水分配系数的公式，研究了以不同极性相上测得的烃类化合物保留指数预测其分配系数的准确性，得出弱极性柱上测得的化合物保留指数能更准确的预测其分配系数，从而为烃类化合物分配系数的测定和预测提供了一种简便易行的新方法。

炭素行业推行清洁生产的污染物排放系数研究

推行清洁生产、减少污染物排放量，根本的方法是控制物料流失。本研究对炭素制品生产过程中的投入产出进行物料平衡测算，确定各工序物料流失总量及污染物排放系数，提出减少流失、降低排污系数的措施。

长江中下游海相三叠系膏盐层与铜(金)、铁矿床

长江中下游海相三叠系膏盖层中含有很大比例的大、中型铜（金）、铁、多金属矿床。膏盐层不仅是铜（金）、铁矿床的主要赋矿层位之一，而且是部分成矿金属的矿源层；膏盐层还为燕山期岩浆提供部分钠质、钾质及挥发组分，影响岩浆演化的方向，改变了含矿流体的性质；另外，从岩体和矿床中金属硫化物中流同位素重硫成分的增高，说明在成者、成矿过程中，膏盐层是硫的供应者之一。因此膏盐层与铜（金）、铁、多金属矿床之间存在着特殊的成因联系。
