At present,there are difficulties of putting a case on file,collecting evidence,judicial identification,and presumption of causal relationship in investigation of environmental pollution cases. In accordance with current situations,it came up following recommendations:(i) widely collecting case clues to solve the difficulty of putting a case on file;(ii) improving the ability of collecting evidence and standardizing the evidence collection,to solve the difficulty of evidence collection.(iii) including the environmental pollution judicial identification system,and unifying the identification standards,to solve the difficulty in identification. It is recommended to use the epidemiological causal relationship theory combined with enough high-quality evidences to solve the difficulty in presumption of causal relationship.展开更多

D. Denton scheme, this paper for the first time numerically solves the 3D flow field of compressor casing treatment, and also explores some boundary singularities and numerical stability. Agreement is attained in qualitative explanations of some, casing treatment test results and its mechanism.展开更多
