沸腾炉底灰的特性研究

用化学分析、Ｘ射线能谱、扫描电子显微镜、偏光显微、激光粒度分析仪等仪器地沸腾炉燃烧所产生的底灰的化学成分、颗粒形貌、粒度、物理性质和工艺性质等系统的分析，并一全国电厂煤粉炉产煤灰的特性进行了对比，结果表明，沸腾炉产底灰具有形态不规则、矿物相中无莫来石矿物、未燃烬炭量低、细底低、比表面积小、火山炭活性高等特点，为沸腾炉底灰的加工利用提供了重要的科学依据。     

粉煤灰综合利用—制无烟型煤

粉煤灰,又称“烟道灰”,是从燃烧装置的烟道气中收集而得到的细灰.目前,国内外对粉煤灰的综合利用极为重视,但大部分都着眼于建材、建筑和农业等方面,而本发明是将粉煤灰作为型煤的掺合料配制型煤,即将粉煤灰与烟煤、褐煤和泥炭混配,再加入适量的添加剂,混匀后经压力成型制成各种形状的无烟燃料.实践证明,只要灰质、煤质和掺比相匹配,可压制成合格的掺灰型煤,达到“煤掺灰,灰代煤、效益高”的效果.该掺灰型煤,具有反应活性高,燃烧效果好,基本无烟等特点,投资少,见效快,效益高,节约能源等.经试烧证明,燃烧排烟中的各种污染物可消减50%以上,节约煤炭约30%以上,并且,每吨掺灰型煤(按售价每吨100元计算)可增收15—20元.     

The functionality of female reciprocal calls in the Iberian midwife toad (<Emphasis Type="Italic">Alytes cisternasii</Emphasis>): female-female acoustic competition?

Female midwife toads (genus Alytes) emit highly variable reciprocal calls of unclear function prior to and during courtship. In some species, female-female competition, expressed as physical fighting, has been reported. Males of Majorcan midwife toads (Alytes muletensis) show phonotactic response to female calls, and females of Iberian midwife toads (Alytes cisternasii) respond differently according to the male call characteristics. In this study, I test the hypothesis of female-female acoustic competition as an additional function of female reciprocal calls. Playback tests indicate that female calls are not clearly involved in female acoustic competition in the Iberian midwife toad, therefore female calls could be directed at males rather than towards competitive females.     

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。     

运用过程分析法有效推进清洁生产

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.
