And the results show that the damage degree of velocity sensitivity is weak in this reservoir,and its damage degree of water sen- sitivity is weak,and at the same time this reservoir is damaged owing to the low acid sensitivity and the middling weak a(?)kali sensitivity.

A new model to evaluate anti dumping injury and the injury degree by multiplayer fuzzy synthetic evaluation was proposed for injury research on anti dumping cases.

Based on the regulations,a method of neural network on fuzzy multifactorial evaluation is used in injury research of anti-dumping cases to optimize enterprises indexes weights in infury and injury degree multifactorial evaluation model.
