河北平原的地面沉降

本文通过分析河北省的水准测量资料，揭示了河北平原的地面沉降情况。整个河北平原都存在着下降的趋势。在大范围的下降背景上，又分布着许多大大小小的沉降中心。这些沉降区多数都是以城市为中心，互相连成一片，下沉速度有逐渐加快的趋势。河北平原地面沉降的原因，除少数有构造运动的因素以外，绝大多数都是集中过量开采地下水造成的。

烟草行业的火灾特点及其监测方法的讨论

烟厂是火灾危险性较大的部门，加强其火灾的早期探测报警是防止火灾发生、减少火灾损失的重要方面。本文对烟厂中各主要生产环节的火灾特点作了分析，指出应针对各部分的特殊性采取适当的火灾探测方法并对现在常用的一些火灾探测技术在烟厂中的适用性作了讨论，认为现有的光束式火灾探测器较适用于内部空间较大的烟厂仓库和厂房。对安装了电视监控系统的企业，建议将其与计算机图象分析技术相结合，增加其防火监视功能。

大空间室内火灾早期自动探测与定位研究

本文在深入研究早期火灾一般燃烧火焰在彩色影像上所呈现的光谱及运动特性基础上，首次提出利用彩色影像实时探测室内火灾的新方法，通过物方坐标与像方坐标的直接线性变换，实现了早期火灾的自动探测与空间定位，实验证明了该方法的有效性与稳健性，且具有巨大的应用前景。     

Industrial Tailings in Traunsee (Austria) Revisited: The Status of 1999

Alkaline tailings from a salt work and a soda plant have been pumped into the southernmost part of Traunsee at Ebensee for many decades. A survey in 1981 showed an accumulation of more than 3 × 10⁶ m³ alkaline mud in the Bay of Ebensee and the existence of slumping structures and turbidites in the profundal zone of the lake. A new survey of the industrial tailings has been performed in 1999. Compared to the earlier survey, the accumulation in the Bay of Ebensee has grown to >4 × 10⁶ m³, which suggests an average yearly input of 90 000 m³. Slumping structures and turbidites document the unstable situation of the tailings near the waste inlet. The lake area occasionally affected by the turbidity currents in the profundal zone has increased to 19%. Within the central profundal area these tailings reach <1 m in thickness.     

火旋风的模拟实验研究

模拟火旋风的实验研究，应用热成像方法获得了火旋风温度场的结构，测量得到火旋风火焰特有的大高度直径比的物理现象；火焰高度比相同燃料，油液面积的油池火高度高，趱戏比油池火直径小。火旋风的切向速度比油池火大，卷吸效果好，可用这一特点来研究熄灭火旋风的火灾。对火旋风火灾机理的研究提出了一种有效的实验方法。     

Major hazards—Thinking the unthinkable

It is a common experience that public administrations tend to shy away from the explicit acknowledgment of quantitative risk levels. Faced with extreme concentrations of population and of industrial activities, including LPG and liquid chlorine storage, within a very small land area, Hong Kong has faced up to the issue of major man-made hazards by “thinking the unthinkable” and adopting explicit risk guidelines. This article describes how these guidelines were developed and the arguments that led to their adoption. It is emphasized that the risk guidelines are not rigid standards but simply a method of focusing decision making and ensuring that any decision to contravene the guidelines is taken at an appropriately senior level in the administration. The way in which the guidelines have been incorporated intimately into the planning and decision-making process is described and details are given on how this has led to the implementation of a variety of measures that have greatly reduced both societal and individual risk from certain types of chemical storage and chemical processing installations in Hong Kong. The opinions in this paper represent the views of the authors and not necessarily those of the Hong Kong Government.
