末端炔烃与亚铜离子反应的实验研究

研究了乙炔亚铜的电子吸收光谱，探讨了末端炔烃和亚酮离子的反应条件，生成物的稳定性和炔亚铜的组成，研究结果表明，末端炔烃的活泼性与介质中氨的含量密切相关，在ｃ（ＮＨ３．Ｈ２Ｏ）／ｃ（Ｃｕ＾＋）摩尔比为２７０～９００的范围内，反应活性最大，易与亚铜离子反应生成炔亚铅，红色乙炔亚铜的组成为ＣｕＣ≡ＣＣｕ，它在含有羟胺的氨性介质中很稳定，不受空气中氧的影响，这些结构为利用生成炔亚铜的以应来鉴定混合气中微笑

化学气相沉积法制备光谱选择性碲膜

用化学气相沉积法制备碲薄膜,其步骤为：通过电化学方法制得碲化氢,碲化氢在室温下分解后在聚乙烯塑料箔上沉积得到碲薄膜.用傅里叶红外光谱仪、紫外/可见/近红外光谱仪、X射线衍射仪及扫描电镜表征碲薄膜的光学性能和结构.结果表明,化学气相沉积法在Mn-O覆盖的聚乙烯塑料箔上沉积得到的碲薄膜在大气窗口（8～13μm）光谱区域具有很高的透过率,同时能阻挡几乎所有的太阳光谱,表明碲薄膜是适用于辐射制冷装置的太阳光辐射屏蔽材料.     

全球气候变化与塔里木盆地古城绿洲演变关系

我国西部地区地形复杂,气候的地域差异性大.特别是青藏高原的突起给塔里木盆地的环境带来了巨大的变化,导致盆地气温降水的突变.从而使塔里木盆地水流分布状态发生改变,导致盆地中原有的古绿洲的蜕变,进而直接影响到整个人类的发展历史.历史研究表明,塔里木盆地气候服从于全球气候变化,并且与某些人文事件,特别是古城绿洲兴盛与消亡有着十分一致的耦合关系.所以,全球环境变化对古城绿洲发展影响重大.

Evolutionary and ecological implications of cardenolide sequestration in the monarch butterfly

Summary Monarch butterflies sequester cardenolides from their larval host plants in the milkweed genusAsclepias for use in defense against predation. Of 108Asclepias species in North America, monarchs are known to feed as larvae on 27. Research on 11 of these has shown that monarchs sequester cardenolides most effectively, to an asymptote of approximately 350 g/0.1 g dry butterfly, from plants with intermediate cardenolide contents rather than from those with very high or very low cardenolide contents. SinceAsclepias host plant species are distributed widely in space and time across the continent, monarchs exploit them by migration between breeding and overwintering areas. After overwintering in central Mexico, spring migrants east of the Rocky Mountains exploit three predominantAsclepias species in the southern USA that have moderately high cardenolide contents. Monarchs sequester cardenolides very effectively from these species. First generation butterflies are thus well protected against predators and continue the migration north. Across the northern USA and southern Canada most summer breeding occurs on a fourthAsclepias species and in autumn most of these monarchs migrate back to Mexican overwintering sites. The ecological implications of this cycle of cardenolide sequestration for the evolution of monarch migration are discussed.     

真蓝甲藻(Gymnodinium eucyanochroum Tseng Sp.nov.)的亚微结构、色素性质及其在藻类进化中的意义

本文报告了在南京发现的蓝色裸甲藻,测定了它的藻胆色素。证明蓝色藻胆蛋白不是山“胞内蓝藻”(Cyanellen)所提供。电子显微镜的扫描表明细胞表面有众多的突起,不是光滑的;横沟内的鞭毛不是“带状”而是由细纤维丝膜状物拉着的螺旋形。透视电子显微镜观察表明,该藻有两个类型的细胞核,即“甲藻核结构”(Dinocaryotic structure)和“真核结构”,(Eucaryotic Structure),真核与叶绿体有一个共同的膜的包被,有一个与原生动物相近似的伸缩泡系统。叶绿体是分枝状,在细胞的边缘位,但也有其它形态。有淀粉颗粒而无“造粉核”或称”“蛋白核”(Pyrenoid),多数位于叶绿体外或之间,类囊体与一般甲藻不同,不是三个排成一条“带”而是两个排列成“带”。有发达的线粒体,和高尔基体;鞭毛不论纵沟内的或横沟内的,其横切面,均为9+2的形式,其纵切面是由纤维丝成束的结构。蓝色色素提取物,可见光最大吸收峰为456nm,与隐藻藻胆色素十分相似。从细胞亚微结构及其色素性质,作者认为它是藻类演化过程中的一个中间类型的甲藻共生体。     

Misuses of biology in the context of the paranormal

Summary Public suspicion of science stems from science's challenging of perceptions and myths about reality, and a public fear of new technology. The result is a susceptibility to pseudoscience. In claiming that creation science is as valid as evolution the creationists misquote scientists and seek to spread their own scientific myths concerning a young age for the earth, an act of creation based on a particular literalist interpretation of the Christian Bible and a single worldwide flood. They use methods of debate and politics, rather than scientific research. A selection of their arguments is examined and the nature of the evidence for evolution is discussed. Problems with the creation science model are noted. In the myth of the hundredth monkey phenomenon, original research is misquoted to denigrate scientific research and support sentimental ideas of paranormal events. The misuse of science is seen as damaging to society because it reduces the effective gathering and application of scientific information. However, pseudoscience provides a valuable guide to gaps in public scientific education.
