三门火山盆地的层状矿床及其与盆地形成演化的关系

浙江三门中生代火山——沉积盆地的形成演化可分四个阶段。每一阶段均伴产有不同成因和各具特色的金属矿床,显示了陆相火山作用较为完整的成矿体系。其中层状矿床具有同生和后生的双重特征,多成因,多来源,是较典型的火山沉积——后期热液迭加改造型矿床。本文着重介绍它的主要特征及盆地的形成演化对火山成因矿床的控制。

Mobilizing environmental sentiment through the media

ABSTRACT

Recent research into the best ways to mobilize people to act on climate change suggests that careful, and relatively positive, emotional framing is critical. However, environmental non-governmental organizations (ENGOs) need to not only mobilize publics, but also attract media coverage. If the media prefers negativity or is skeptical of ENGOs’ emotive appeals, are ENGOs’ emotional frames damaging their ability to gain media attention? Quantitative sentiment analysis is used to identify emotional framing in a targeted case study of 350.org’s public press releases and their subsequent media coverage. The results suggest that appropriate emotional frames for mobilization are not necessarily detrimental to gaining media attention, and that ENGO press releases influence media coverage, when they are used. Several concrete suggestions emerge for how ENGOs might use press releases more effectively, if they seek to influence the media’s emotional tone on climate change.

Study of oil-water partitioning of a chemical dispersant using an acute bioassay with marine crustaceans

The toxicity of seawater dispersions of a chemical dispersant to two marine crustaceans was investigated in the presence and absence of various quantities of a non-toxic mineral oil. From the results and a physical-chemical partitioning analysis, a limiting value of the oil-water partition coefficient of the toxic compounds is deduced suggesting that essentially all of the toxic compounds in the dispersant will partition into solution in water following dispersant application to an oil spill. This conclusion simplifies interpretation and prediction of the toxic effects of a dispersed oil spill.The combined bioassay-partitioning procedure may have applications to the study of the toxicity of other complex mixtures such as industrial effluents.     

复杂地形空气污染预报模式的研究

本文依据一个同时包括地形、热力以及摩擦等因素在内的，能够较真实地反映复杂地形情况下，大气运动基本特征的近地层水平流场二维数值模式，将其扩展成三维模式。在此基础上，从平流扩散方程出发，建立了一个与上述流场相应的浓度场预报模式。经与实测值比较，该预报模式具有较好的可靠性和适用性
