By means of solution treatment at different temperatures, creep properties measurements and microstructure observations, an investigation has been made into the influence of solution temperature on the elements segregation and creep behaviors of a directionally solidified nickel-based superalloy at intermediate temperatures. Results show that after solution treated at 1230°C, the bigger composition...
Various gaseous pollutants generated in coking production have some impact on human health. Owing to BaP has carcinogenicity effect, teratogenicity effect and mutagenic effect, therefore , the assessment of human health risk duo to the coking process of project implementation released into the environment has always been a hot topic in academic research .This study, combined with a coal city in China...
Safe disposal of medical and pharmaceutical wastes has been extensively concerned by the society nowadays. If disposed improperly, they are very likely to produce secondary pollution. Incineration is considered as one of the most feasible methods.

As the development of industrialization and urbanization, the potential impact on environment and human health caused by air pollution has been widely concerned, especially the health effects assessment. Qitaihe city is an emerging coal city. Accompanied by the construction and development, the atmospheric quality was influenced to some extent. In this paper, risk assessment methods were used to research...
To enhance the response capacity to the fatal pollution events of river region, an emergency decision-making case base system based on Case-Based Reasoning (CBR)/ Rule-Based Reasoning Technology (RBR) and Analytic Hierarchy Process (AHP) is developed. The fatal pollution events of river region during the past ten years are counted and analyzed from the perspectives of number and reasons. (i)The AHP...
