论大学生创业融资制度的优化

我国大学生创业发展缓慢,其中一个关键因素就是创业融资困难。对融资制度的深入了解和掌控,才能为大学生创业融资问题提供有力的制度支持。在对我国现有大学生创业融资制度的供给现状详细分析的基础上,借鉴发达国家的融资模式,提出强化大学生创业融资的制度需求、改革国有商业银行体系、建构以市场为导向的金融服务体系以及完善大学生创业融资的配套公共服务等优化措施,望能为提升我国大学生在创业过程中的融资理论认知提供借鉴,促进大学生创业更好发展。

A Comparative Study of Agricultural Informatization for China and Beyond

[Objective] The aim was to discuss the classification of agricultural informatization in some developed countries, and conclude the revelation to Chinese agricultural informatization. [Method] The research was made by comparison, according to the development impetus. [Result] The results show that foreign agricultural informatization is mainly divided into three categories： the first category is the government leading; the second category is the industry self-help; the third category is typical demonstration. Since the reform and opening, Chinese agricultural informatization has made considerable achievements. [Conclusion] The agricultural informatization is significant to promote the update of the traditional agriculture, and it is also essential to Chinese agricultural sustainability.

利用DNA数据库破获九年前命案之后的思考

在公安机关对案件的侦破过程中,利用DNA数据库破案的效用越来越明显,但为了发挥DNA数据库的更大效益,有些问题是需要我们正视和解决的。通过对利用DNA数据库破获九年前命案的过程进行反思,力争能发现和解决其中的一些问题。

基于快速遗传算法的指纹匹配

针对标准遗传算法(GA)存在收敛速度慢且容易早熟的现象,提出一种快速GA算法,将其应用于全局点模式指纹匹配中。该算法通过在迭代过程中逐步缩小种群规模与优秀个体数目,降低突变概率,并尽量选择适应值高的个体,使匹配过程快速收敛于全局最优解。实验结果表明,该算法能提高指纹匹配的速度和准确率。

Application of extension neural network to safety status pattern recognition of coalmines

In order to accurately and quickly identify the safety status pattern of coalmines,a new safety status pattern recognition method based on the extension neural network (ENN) was proposed,and the design of structure of network,the rationale of recognition algorithm and the performance of proposed method were discussed in detail.The safety status pattern recognition problem of coalmines can be regard as a classification problem whose features are defined in a range,so using the ENN is most appropriate for this problem.The ENN-based recognition method can use a novel extension distance to measure the similarity between the object to be recognized and the class centers.To demonstrate the effectiveness of the proposed method,a real-world application on the geological safety status pattern recognition of coalmines was tested.Comparative experiments with existing method and other traditional ANN-based methods were conducted.The experimental results show that the proposed ENN-based recognition method can identify the safety status pattern of coalmines accurately with shorter learning time and simpler structure.The experimental results also confirm that the proposed method has a better performance in recognition accuracy,generalization ability and fault-tolerant ability,which are very useful in recognizing the safety status pattern in the process of coal production.

Building Long-Term Care Insurance System in China

The objective is to explore the foundation of the elderly long-term care insurance system in China, which is to face the problem resulted from aging of the population. Adopting the contrastive analysis to introduce briefly the long-term care insurance system in German, Japan and America for our learning. Therefore, China＇s long-term care insurance system could not totally indiscriminately imitate the mandatory long-term care insurance system in German and Japan, it also could not copy the business model of nursing insurance system in America. The conclusion is that long-term care insurance system in China should use the experience of developed countries based on the basic national conditions, doing some relative works, such as establishing policies and regulations, strengthening personnel training, and improving the market specification.

Production of Top-Pions Associated with W Boson at Next Generation γγ Colliders

In the context of topcolor-assisted technicolor （TC2） model, we study the charged and neutral top-pions production process γγ →W＋ ∏t-∏t^0. We find that the production cross section is larger than that of the process γγ→ W＋ H-H in the minimal supersymmetric standard model. With reasonable values of the parameters in the TC2 model, the cross section can reach the level of a few fb. Furthermore, the flavor-changing （FC） decay mode ∏t^0 → te^- is the best channel to detect the neutral top-pion due to the clean SM background. With a large number of events and the clean background, the neutral top-pion should be observable at future linear colliders operating in γγ mode at the TeV energy scale.

Problem-Solution in English vs. Qi-cheng-zhuan-he in Chinese:Are They Compatible Discourse Patterns?

本文旨在探讨两个方面的问题:一、验证英语最小语篇模式"问题-解决"是否适用于汉语语篇的分析,尤其是否可以用来解释以典型的汉语修辞模式"起-承-转-合"为语篇建构格局的篇章。二、对比研究上述两种英汉基本语篇模式的语步,揭示它们的相似性与差异。通过抽样文本分析发现,英语的"问题-解决"语篇模式同样适用于汉语语篇的分析,但"问题"语步时有不出现的情况,语篇结构呈因-果型;而在英语语篇中,"问题"是不可或缺的语步,语篇的组建与信息的组合呈对立型。尽管英汉基本语篇模式存在某种差异,但作者认为,"问题-解决"与"起-承-转-合"可以被看作是同一语篇模式的两个变体。中国传统修辞模式并不是造成中国学生使用"螺旋式"或"间接法"构思谋篇的全部动因,而社会和教育等因素可能是值得我们探索的重要领域。
