For the fourteen enzymes assayed, 31 loci were recorded. The results indicated that all the isozymes examined were obviously tissue-specific. The expressions of SOD＊, GDH＊, G3PDH-2＊ and ADH-2＊ were detected only in liver, SDH-1＊, MDH-1＊ and ADH-1＊ only in muscle, and LDH-B＊ and LDH-C＊ only in eyes. In comparison, MDH-2＊, GPI-3＊ and SDH-2＊ were detected in all tissues examined. Other loci examined were detected in a variety of tissues. Muscle and liver were selected to detect the isozyme variation of the two geographic stocks of Qingdao and Weihai, Shandong Province, China. The percentages of polymorphic loci （P0.99） were 29.17% and 25.00%, the observed heterozygosities （H0） were 0.028 ±0.014 and 0.040 ± 0.019, and the expected heterozygosities （He） were 0.039±0.017 and 0.052±0.022 in Qingdao and Wethai stock, respectively. The coefficient of gene differentiation （Fst） and genetic distance （D） between the two stocks was 0.012 and 0.0011, respectively, indicating that the genetic differentiation is low between them. Compared with other species of Pleuronectiformes, both the percentage of polymorphic loci and the mean heterozygosity ofK. Bicoloratus were at a middle level.展开更多

An accelerated simuIated arlneaIing aIgorithm is developed for automatic web document classification. The web document classification problem is addressed as the problem of best describing a match between a web query and a hypothesized web object. The normalized term frequency and inverse document frequency coefficient is used as a measure of the match. Test beds are generated on - line during the search by transforming model web sites. As a result, web sites can be clustered optimally in terms of keyword vectofs of corresponding web documents.展开更多

Pay as one of the important means of incentive talents, plays an important role in talent organization plan. Compensation management has become the core content of enterprise human resources management, compensation mode is about employee compensation management to study and the trend of the style, it provides reference for compensation managers implement compensation management activity basic paradigm or frame type style. Different modes of compensation, conveys the organization of different development direction, in determining job satisfaction, stimulate staff＇s work motivation, plays an important role in the enhancement enterprise cohesion, etc. This article through to the state-owned enterprise and private enterprise specific comparison on the differences of two compensation modes, to explore the adaptability of different mode of enterprise, for other enterprises to provide reference for reasonable and effective compensation system.展开更多
