The fat content in washed cashmere was determined using Soxhlet fat extraction unit and fiber grease extractor quickly, respectively. The results show that no significant difference was found between these two instrumental methods, and reliability of fiber grease extractor quickly was confirmed for deter- mination of fat content in washed cashmere. Therefore, the fiber grease extractor quickly can meet current standard for determination of fat content in washed cashmere.展开更多

This domain-independent algorithm with multi-layers of filters is a hybrid of statistic-oriented and rule-oriented methods. Utilizing the features of domain terminologies and the characteristics that are unique to Chinese, this algorithm extracts domain terminologies by generating multi-word unit （MWU） candidates at first and then fihering the candidates through multi-strategies. Our test resuhs show that this algorithm is feasible and effective.展开更多
