There are some deficiencies in the development of positive psychology because of short term of studying. Those deficiencies include: supreme discourse, absence of adequate objects, lack of longitudinal studying, disjointing from former psychological correlating research.

由于积极心理学运动兴起的时间较短，因而在其发展过程中还存在一些问题，这些问题主要包括：表现出一定的话语霸权、研究对象不够全面、缺少有说服力的纵向研究、和早期心理学的一些相关研究存在一定的脱节。

Firstly, there are less secure and efficient threshold schemes; secondly, the research on multi-secret sharing is rather weak; thirdly, usual verifiable secret sharing don't consider the partners' anonymity, while it is just people's expectation. Last but not least, the problem of variety on shares is becoming a more obvious restrict of efficiency, especially in the facets of the lost and being districted of shares. On the application of verifiable secret sharing, there are also two inadequates : on the one hand , verifiable secret sharing has been used in much threshold cryptography but in less verifiable signatures.

然而，经过认真总结、分析该领域目前研究的发展状况（具体结果将在第一章给出），我们发现在可验证秘密分享的研究方面，仍有下列四个不足之处：一是现有的安全、高效的门限方案不多；二是对多秘密分享的研究非常薄弱，在已有的文献中还见不到安全、实用的可验证多秘密分享方案；三是通常的秘密分享方案没有考虑秘密分享者的匿名性，而这恰恰是人们所希望的；四是秘密分享者的动态管理问题已经越来越明显的制约现有方案的安全，尤其是密钥份额丢失或被破坏时如何恢复更是没有被深入探讨。

Although great achievements have been made in recent years, such as Jiang Lihong"s Explanation for Words in Dunhuang Narrative Literature and A Dictionary for the Language in Dunhuang Documents, Huang Zheng and Zhang Yongquan"s Collation and Annotation to Dunhuang Narrative Literature, and a lot of papers published in various academic journals, there are still many Colloquial words with their meanings unknown that are worth more thorough researches. In light of this, this paper attempts to make a philological explanation for 34- Colloquial words in Dunhuang narrative literature which are divided into 19 groups through employing such methods as analyzing and inducing, seeking synonyms or ardnyms according to the mutual annotation or different words expressing the same meaning, and exploring their etymologies.

虽然近年来，对敦煌变文俗语词的研究取得了丰硕的成果，如蒋礼鸿《敦煌变文字义通释》、《敦煌文献语言词典》，黄征、张涌泉《敦煌变文校注》等著作，以及许多散见于各种期刊上的单篇论文，表明这一研究正在呈现出繁荣兴旺的喜人景象，但是由于敦煌变文来自民间的土壤，采取的是接近当时的口语，所以其中不明其义的俗语词还是连篇累牍，信手拈来，仍然值得我们去研究。

Researchers feel that although the study was conducted on preschoolers, the results can be extrapolated for children of any age.

研究人员认为虽然这项研究是在学龄前儿童中进行的，但是根据这个研究可以推算出这种方法使用与任何年龄段的孩子。

The application results from fluorination showed microwave heating could accelerate chemical reactions markedly. The reaction time could be shortened 50% at least than that of conventional heating. The relationship between fluorinating agents\' structure and their activity was studied systematically. In addition, an anhydrous KF with higher activity was prepared by using expansion effect of microwave heating. As we known, solvents were very important to reaction. The comprehensive study showed some less polar aromatic solvents could be used as dipolar solvents. In addition, they had better effect than dipolar solvents in some occasions, such as fluorination of chlorobenzaldehydes and chlorinated diphenyl ketones etc. The primary applications of ionic liquids were also studied which indicated reactions with ionic liquids as solvents were more efficient and simple.

研究表明，微波是一种节能高效的加热方式，在微波作用下的卤素交换氟化反应具有反应速度快、转化率高、选择性好的优点，其反应时间可较常规加热缩短50%以上；同时也系统地研究了氟化剂种类及制备方式对其反应活性的影响，并利用微波加热的膨化作用制备出了一种活性较高的KF，其活性与喷雾干燥KF相差不大；溶剂对反应具有重要的作用，在此系统地研究了强极性非质子溶剂和中等极性非质子溶剂的应用情况，发现一些中等极性的非质子溶剂如硝基芳烃和氯代芳烃类溶剂在氯代苯甲醛类化合物的氟化反应中具有比强极性非质子溶剂更好的使用效果。

This article utilizes qualitative and the quantitative investigation method construction finance early warning system, simultaneously also emphasized the financial crisis forewarns the system construction the cash current capacity analytic method; Thus causes the enterprise prompt discovery crisis, and formulates suits the enterprise the financial risk guard measure; Finally carries on the analysis and the research to the Luoyang Glass Limited liability company's financial crisis, has realized the theory and the real diagnosis research unifies.

本文运用定性和定量研究方法构建财务预警系统，同时又强调了财务危机预警体系构建的现金流量分析法；从而使企业及时发现危机，并制定出适合企业的财务风险防范措施；最后对洛阳玻璃股份有限公司的财务危机进行分析和研究，实现了理论与实证研究相结合。

Every innovation of research methods impels economics to maturity and forces it to develop into a higher level.

确定研究方法是经济学的首要出发点，不同的研究方法可以划分出不同的流派，研究方法的每次革命、创新又推动着经济学的成熟和向更高层次的发展。

In recent 20 years, with lucubrating on corporate governance worldwide and springing up of behavioral corporate finance theory, it not only remodeled and developed the theoretic hypothesis of traditional corporate financing, but also shown up a new viewpoint of research on mechanism of the acts of corporate investment, in frame of the combination of governance mechanism and behavior character of financial decision-making body.

近二十年来，公司治理研究在世界范围内的深入和行为公司财务理论的兴起，不仅重塑和发展了传统公司财务研究的理论假设，而且越来越呈现出在治理机制与财务决策主体行为特征相结合的框架内探索企业投资行为机理的崭新研究视角。
