摘要:
We investigated the vegetation of sphagnum mire at Erxianyan in Western Hubei Province and analyzed the species composition, association types, dominance and importance value of species. The results show that the species composition and association type of the mire is relatively rich. 111 species of plants, belonging to 85 genera of 51 families, were recorded. The mire vegetation can be divided into 11 associations. Among these, there are 7 Sphagnum-dominated associations. Sphagnum palustre and Juncus setchuensis appears in all of the 7 Sphagnum-dominated associations. The average dominance of Sphagnum in the plots is 90.70%. The importance value of Sphagnum is greater than that of other species in 77.78% sample plots. The results suggested that by human's interference the sphagnum mire at Erxianyan may be regressive succession in two paths: one is to be a community with single dominant species and exiguous species after drainage; the other is to be a weed community with abundant species but no dominant species by intensive interference.

摘要:
This thesis does several levels of research on Software Designed Radio (SDR) baseband processing technology. Analysis and comparison are given on different software realization methods. A new Base Band Unit (BBU) software framework is also proposed. The baseband protocol processing software and control software design criteria are discussed. This thesis suits the development and application of future software radio, and provides a general software platform for baseband signal processing, which may have certain referance value for future research.

摘要:
In the 2008 Beijing Paralympics Games, China's national women's wheelchair racing team of 4 x 100m relay achieved the gold medal for 52.43 seconds, before the game the individual 110m speed time curves for relay members are obtained in the usage of video recording analysis methods and the individual starting durations are also recorded, combined with those, the optimal starting distances are calculated by using the numerical integral methods and which are compared with the real starting distances used in the relay training. Results: the starting distances are relative short in relay training for national women's wheelchair racing team; the hand-take over may be completed in the former relay regions under the relay tests based on the optimal starting distance bounds, and so there are relative improvement in relay achievements. Conclusions: the starting distances need be extended in relay training for national women's wheelchair racing team; calculated optimal starting distances may be the reference when starting distances are set up for relay technique training.

摘要:
With the purpose of exploring the development trend of Wushu, an analysis on status quo of Wushu was discussed, including its failure of being formal Olympic events, unfull development in Physical education field, lack of heirs in mass sports and unbalance between the Chinese competitive Wushu and Chinese traditonal Wushu. Comparing the development status quo of Wushu, Janpanese Judo and Korean Taekwondo in different fields such as competitive sports, school sports and mass sports, it is discovered that present studies about Wushu, Judo and Taekwondo were mostly analyzed in superficial phenomenon. However, rare researches were about the social reasons for the weakness of development in Wushu culture by the angle of sociology. This paper, utilizing methods of the sociology, found out that there were several factors about the successful prevalence and development of Taekwondo and Judo, and emphasized the reasons of the weakness of development in Wushu culture. As a result, several developing strategies were approved in order to meet modern people's needs of sports culture and protect the Wushu's spirit.

摘要:
This paper studies the problem of allocation the qualitative education resource where condition is relatively backward in China. By comparison of the four options to select one of the most suitable solutions which can realize the educational resource sharing in the particular situation. At last, we proposed a algorithm to solve the problem. Simple as it is, but it may be useful to education fair in our country. And may be useful in the world where the situation familiar with China.

摘要:
The paper discusses the sensitive period of youth football training and corresponding teaching and training theory through literature data research, questionnaire and logical reasoning. This paper firstly expounds the concept and influencing factors of sensitivity and sensitive period, and further points out the characteristics of youth sensitive period. Then the application of teenagers' sensitive period is analyzed and suggestions are raised from four aspects: cultivation of teenagers' interests in soccer, training of flexibility and basic skill, capture of the sensitive periods, and individualized instruction. The discussion focuses on analyzing respective sensitive age period, training mechanism and notes of five qualities, speed, strength, stamina, flexibility and agility. In conclusion, it is important to capture the sensitive period and it is more important to extend this sensitive period in order to gain a better training effect. This rule applies not only to football training, but also to the training of other sports activities. Moreover, the most important thing for the PE teachers and coaches is to explore and extend the sensitive period of special quality and technology of young athletes and design a suitable training plan for each of them. The rational application of sensitive period plays an important role in the physical development and cultivation of the youth.
摘要:
Hyperspectral data have the characteristics of massive data and high dimensions, which lead lots of difficulties for spectrum analyzing and processing. Especially spectral feature extraction and analysis are the foundation of further processing. In this paper, we discuss a number of spectral data processing algorithms for spectral feature extraction and analysis. The main contribution is that we combine both Douglas-Pcucker (DP) algorithm and spectrum derivative algorithm to extract spectral absorption characteristics from the rock and mineral spectral data. The experiments indicate effectiveness while using the proposed algorithms for spectral feature extraction.
