用硫酸烧渣法处理煤系硫铁矿

本文提出一种以废治无污染的处理煤系硫铁矿的工艺。该工艺利用硫酸生产过程中所产生的废渣中的氧化铁，经处理后在硫酸介质中与硫铁矿反应，使硫铁矿中的硫和铁及烧渣中的铁资源得到充分的回收利用，既有利于环境保护，又具有良好的经济效益。     

上海地区高空气流长距离输送轨迹及其与酸雨的关系

分析了影响上海地区的高空气流输送轨迹。不同月份影响上海的高空气流来向不一。轨迹输送路径与天气系统的变化密切有关,且与上海地区出现的酸雨有关。研究表明,上海地区的酸雨,除与局地污染有关外,还与远处输送的外来污染有关。这些外来污染影响,主要来自上海西南向的北部湾和两广等地。也有部分来自东北——东方向的南朝鲜和日本西部地区。

Gamergates in the myrmicine genus <Emphasis Type="Italic">Metapone</Emphasis> (Hymenoptera:Formicidae)

Gamergates (i.e. mated reproductive workers) are mostly known from ant species within the Ponerinae. We report here the discovery of gamergates in two species of the subfamily Myrmicinae. Until now, mated reproductive females in colonies of myrmicine species have been considered morphologically distinct from the worker caste. However, in two species of the myrmicine Metapone (Metapone madagascarica and a newly discovered, not yet described Metapone species) all workers have six ovarioles and a spermatheca; and some of them are mated. There are no morphological differences between mated and non-mated workers. Field observations and laboratory studies indicate that colonies of the Metapone species can reproduce with gamergates only.     

Vocal acrobatics in a Chinese frog, <Emphasis Type="Italic">Amolops tormotus</Emphasis>

Although amphibians are highly vocal, they generally emit only a limited number of acoustic communication signals. We report here the extraordinarily rich vocal repertoire of Amolops tormotus, a ranid species in China. These frogs produce countless vocalizations, some of which share features of birdsong or primate calls, e.g., ultrasonic frequency components, multiple upward and downward FM sweeps, and sudden onset and offset of selective harmonic components within a call note. Frame-by-frame video analysis of the frog's calling behavior suggests the presence of two pairs of vocal sacs that may contribute to the remarkable call-note complexity in this species.

Inventory of emissions from major air pollutant categories in Turkey

In this study, an inventory of air pollutant emission estimates from major air polluting sources in Turkey for period between 1985 and 2005 with 5-year intervals were estimated. Inventory covers anthropogenic sources of five major air pollutants of particulate matter, sulfur dioxide, carbon monoxide, nitrogen oxides and non-methane volatile organic compounds. Their break-down with respect to main activity sectors were shown and their distribution by the largest industrial source categories were worked out as annual estimates. This inventory and its analysis point to serious environmental implications of air pollutants and a need to develop a policy plan for reducing these emissions.     

AMS方法在大气气溶胶来源研究中的应用

在我国自己建立的加速器质谱计（ＡＭＳ）技术的基础上,利用＾１４Ｃ的特征的生物来源示踪性能,将ＡＭＳ技术运用于我国大气气溶胶来源的研究,我们建立了大气气溶胶采样－－石墨碳制备－ＡＭＳ测定的全部样品处理过程,对北京市中关村地区、东单地区在采暖期和非采暖期的气溶胶样品和湖南南岳、山东青岛的气溶胶及这些地区的地表土进行了ＡＭＳ测定,将多元统计方法与ＡＭＳ方法相结合,从中分析这些样品中微量元素组分和含碳 分
