中国发展生物质能源的战略措施思考

能源连人类社会赖以生存和发展的重要资源。随着中国经济的持续发展，能源与环境对经济发展的制约作用逐渐得到显现．能源问题与环境问题已经成为国家发展的战略性问题。因此发展生物质能是解决中国能源紧张的重要突破口。发展生物质能的战略措施是建立生物质能源的产业体系。即相对于传统产业体系的第二产业体系。具体战略阶段是：2000—2010年实验探讨阶段（初级阶段）；2020—2030年推广应用阶段（发展阶段）：2030年一2050年优化提出阶段（提高阶段）。生物质能源的发展战略有助于“三农”问题的解决即农村小康社舍的建设；有助于减轻环境压力；有助于维护国家能源安全。

A new design of groundwater sampling device and its application

Compounds in the atmosphere contaminate samples of groundwater. An inexpensive and simple method for collecting groundwater samples is developed to prevent contamination when the background concentration of contaminants is high. This new design of groundwater sampling device involves a glass sampling bottle with a Teflon-lined valve at each end. A cleaned and dried sampling bottle was connected to a low flow-rate peristaltic pump with Teflon tubing and was filled with water. No headspace volume was remained in the sampling bottle. The sample bottle was then packed in a PVC bag to prevent the target component from infiltrating into the water sample through the valves. In this study, groundwater was sampled at six wells using both the conventional method and the improved method. The analysis of trichlorofluoromethane（ CFC-11 ） concentrations at these six wells indicates that all the groundwater samples obtained by the conventional sampling method were contaminated by CFC-11 from the atmosphere. The improved sampling method greatly eliminated the problems of contamination, preservation and quantitative analysis of natural water.     

考虑声散射的街道交通噪声预报模型

提出一种预报典型的两侧密集分布建筑物的城市街道交通噪声ＬＡ１０和ＬＡｅｑ声级的计算机仿真模型。模型依据一种修正的虚声源原理。它不仅考虑发生于建筑方面的镜象反射和表面吸收，而且考虑了由于墙面的粗糙性所引起的发生于有限尺寸建筑表面声散射的影响。与实测比较表明本模型可得出良好的预报结果。通过对散射强度加以变化可估计表面声散射对预报声级的影响。结果表明，即使在一个相当混响的场合，镜象反射声能对扩散反射声能

Effect of domestic sewage on growth of phytoplankton-mathematical model

A mathematical model relating to the change in phytoplankton biomass in the period of growth and nutrient concentration in the media was proposed on the basis of the Monod equation and was testified by simulation experiments. Analysis of the experiment data showed that: the half-saturation constants for growth Kp (μmol/L) for Skeletonema, Chaetoceros and Prorocentrum were 5.52, 1.90 and 0.46, respectively; the balance between stimulation of nutrients and the inhibition of some other materials was found in the effect of domestic sewage on algal growth and the stimulation played a leading role; domestic sewage was more stimulative on dinoflag-ellate than on diatom and chlorophyte when the assemblage of the algae was cultured. The experiment suggested that mathematical model reasonably explained the characteristics of phytoplankton growth in different nutrient conditions and was worthy to be further improved for eutrophication prediction in off-shore water.
