新疆诺尔特地区石炭纪火山岩的成岩机制

诺尔特地区位于阿尔泰北部山区 ,西伯利亚板块西南缘。诺尔特地区石炭纪火山岩赋存于下石炭统红山嘴组中 ,火山岩属钙碱性系列 ,主要是酸性陆相火山岩。火山岩岩浆起源于诺尔特地区中地壳位置 ,成岩物质来源于地壳。痕量元素协变关系、皮尔斯元素比值、元素丰度关系及氧同位素特征的研究表明 ,石炭纪火山岩具有明显的部分熔融成岩机制的特点 ,而结晶分异作用特点不明显 ,无混合作用特点的显示。石炭纪火山岩为部分熔融作用的产物。     

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.

膜生物反应器处理印染废水的研究进展

印染废水是一种有机物含量高、色度深、生化性差、难降解的工业废水,采用传统的污水处理工艺很难达到排放标准,对新型、高效的处理工艺的研究越来越受到人们的关注.膜生物反应器是一种新型水处理技术,具有传统废水处理工艺所无法比拟的优势,通过膜生物反应器处理后的印染废水,甚至达到了回用水标准,在此基础上对现在研究较多的膜生物反应器的改进技术进行了综述并指出了还有待解决的问题,为将来的发展提供参考和依据.     

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.
