大鹏湾春季海水理化因素与拟尖刺菱形藻种群密度的灰色系统模型研究

对1990年3月30日－6月25日在大鹏湾盐田海域的海水采样结果，用灰色理论的系统分析方法研究并计算大鹏湾地区海水中的拟尖刺菱形藻与浮游动物数量等15个海水理化因子变化的灰关联度，关联排序结果表明：浮游动物、Fe、浊度、Me、DO、V、Se、酸碱度、盐度和温度对拟尖刺菱形藻的种群增殖态有着较大的影响。进而建立灰色系统模型{GM（1，h )}对拟尖刺菱形藻种群增殖的动态辨识分析。

新时期消防工作发展思路

随着我国社会主义市场经济的发展和社会管理体制的变化 ,消防工作也面临着新形势。笔者认为 ,消防工作社会化是适应形势发展的必然要求 ,要在全社会建立起各级人民政府领导下的单位责任自负、隐患自除、风险自担 ,公安消防机构依法实施监督的消防社会化运行机制。新时期消防工作应通过以下方式实现社会化 :进一步完善消防法规体系 ;强化消防安全的基础性地位 ;加强宣传普及基本的消防知识 ;发展消防安全中介组织 ;建立消防安全评价制度和科学评价体系 ;依法实施消防监督

Effects of planned expansion of waste incineration in the Swedish district heating systems

Recent targets for reduced amounts of waste to landfills in Sweden will result in a large increase in waste incineration with recovery of energy, used primarily for district heating. The aim of this study is to investigate what changes in the usage of other fuels and technologies for district heat production would be caused by this increase. A questionnaire was sent out to the largest district heating companies, and simulations in an energy systems model were carried out. The analysis shows that increased waste incineration reduces the demand for other fuels, especially biomass, for district heat production. The effects include reductions in operating hours as well as the avoidance or postponement of investments in new plants for district heat production. Increased waste incineration will also lead to a greater use of district heating in Sweden.     

SUMMER LOW FLOWS IN NEW ENGLAND DURING THE 20TH CENTURY1

ABSTRACT: High springtime river flows came earlier by one to two weeks in large parts of northern New England during the 20th Century. In this study it was hypothesized that late spring/early summer recessional flows and late summer/early fall low flows could also be occurring earlier. This could result in a longer period of low flow recession and a decrease in the magnitude of low flows. To test this hypothesis, variations over time in the magnitude and timing of low flows were analyzed. To help understand the relation between low flows and climatic variables in New England, low flows were correlated with air temperatures and precipitation. Analysis of data from 23 rural, unregulated rivers across New England indicated little evidence of consistent changes in the timing or magnitude of late summer/early fall low flows during the 20th Century. The interannual variability in the timing and magnitude of the low flows in northern New England was explained much more by the interannual variability in precipitation than by the interannual variability of air temperatures. The highest correlation between the magnitude of the low flows and air temperatures was with May through November temperatures (r =?0.37, p= 0.0017), while the highest correlation with precipitation was with July through August precipitation (r = 0.67, p > 0.0001).
