冲击水浴喷雾式除尘器的应用

介绍了冲击水浴喷雾式除尘器在柳钢焦化厂的应用试验情况，制作安装，调试运行后检测鉴定表明，冲击水浴喷雾式除尘器应用在冶金焦末粉尘上，不但操作简单，维护方便，除尘效率高，效果好，而且成本低廉，只有电除尘器或布袋除尘器的20%左右。     

深冲钢板塑性变形形为研究

单相塑性材料的强度和塑性基本上是分别研究讨论的。此文以低碳深冲钢板为例,从能量观点出发,讨论了强度和塑性的内在制约关系,唯象地提出了单相塑性材料塑性破坏的判据,并解释了几个实验现象。此文的研究有助于加深对深冲钢塑性变形形为的理解。     

Organochlorine residues in the avifauna of Tamil Nadu (Southeast coast of India)

Pollution due to persistent pesticides is not a regional but a global problem. Organochlorine pesticides are persistent chemicals, stored and accumulated in the tissues of a wide variety of invertebrates and vertebrates including marine species. In the present study the organochlorine residues HCHs, DDTs and PCBs were measured in different trophic groups of birds (scavengers, inland piscivores, coastal piscivores, insectivores, granivores and omnivores) collected from Tamil Nadu Coast, India. The residue accumulation as a function of sex did not depict distinct variation. However, females had lower residue levels than males in terms of their mean weight and feeding habits. A continuous monitoring programme is recommended to establish the studied organisms as indicator species.     

论土地持续利用

在世界上有两种可持续发展思路，一种是西方发达国家的重保护的可持续发展思路；一种是以发展为前提，保护自然资源的可持续发展思路。土地持续利用的思想是在可持续发展的进程中不断发展的。我国要保证土地持续利用，满足未来对食粮和建设的需求，应建立起同土地持续利用相适应的土地持续利用制度和土地持续利用机制
