[Method] Cherry valley duck, Jinding duck, White muscory duck and Suma duck （ Cherry valley duck ♂ × Jinding duck ♀ ） were fed for 10 weeks to observe the ultrastructure of muscle fiber by electron microscope, and the myofibril diameter and sarcomere length were also determined. [Result] The myofibril diameter increased with ages. Sarcomere length and myofibril diameter did not change significantly with the increasing ages （P〉0.05）. The myofibril diameter of White muscory duck and Jinding duck were thicker, while that of Cherry valley cluck and Suma duck were thinner. Moreover, the sarcomere length of Suma duck and White muscory duck were longer, while that of Cherry valley duck and Jinding duck were shorter. Thus, the basic characteristics of ultrastructure of muscle fiber were consistent in these duck breeds.[Conclusion] The results have an important meaning for duck breeding.展开更多

The results showed that the growth curves of Minghua black minks could be fitted very well by Logistic model and Gompertz model （the degree of fitting FF≥0.99）, but Gompertz model was better at fitting and predicting their weight.展开更多

According to soluble solids content, there are four stages during fruit development phase named comparatively stable period, slow increase period, rapid increase period and stagnating increase period. Fruit firmness change exhibits two periods, i.e. slowly declining period and rapidly declining period. There is an obvious corresponding relation between the changes of fruit firmness and the soluble solids content, i.e. the rapidly declining time of fruit firmness corresponds with the rapidly increasing time of soluble solids content. According to the experiment, the best picking periods of ‘Fengyue’and ‘Cuiyu’are mid September to mid October and early October to early November, respectively.展开更多

Using theoretical study combined with field survey,this paper listed Lu Jiazhi,Daishan Dongsha Town,Putuo Mountain,Zhujiajian,Shenjiamen,Changzhi Island,Mayi Island,Taiyang Valley,Zhujiajian Baishan,and Taohua Island in Zhoushan Islands. From three core rules of cultural industry cluster,namely,rules of combination and extension of industry chain,rules of location advantage and selection,and rules of industrial agglomeration and linkage,to fully reveal inherent rules and development ideas for marine cultural industry cluster in Zhoushan Islands. It came up with recommendations for developing marine cultural industry cluster in accordance with resource endowment characteristics of each island. It is of certain directive significance for the development of marine cultural industry cluster in Zhoushan Islands.展开更多

The plenary session was convened at a pivotal stage in comprehensively building a well-off society and comprehen- sively deepening reform. It was the first of its kind with the theme of the rule of law and was a landmark event in China＇s legal construction. The Journal interviewed Professor Luo Haocai, who is also president of the China Society for Human Rights Studies （CSHRS）.展开更多

April 11, 2007, SAC announced a survey on a standards system for enterprise energy efficiency. According to the announcement, 'Rules for the Composing of a Standards System for Enterprise Energy Efficiency' shall be developed based on the results of the survey. The rules are designed to better manage energy efficiency through standards and to give advice to companies on energy efficiency. In this way, China will be able to assist companies in energy efficiency on a more professional, strict, and comprehensive basis.……展开更多
