Also, a learning style involves a theoretical model that proposes that individuals have preferred ways in which they learn; learning styles typically involve visual representation, vocal explanations, and practical examples; experiential learning proposes several ways in which an educator can accommodate these learning styles, although all such styles have a bias toward practical expression and place less emphasis on theoretical expressions of learning.

同时，学习风格包含一种理论模型，主张学习者个体有较喜爱的学习方式，并通过这种方式来学习。它通常包含视觉表征、有声解说和实例；经验学习提出了一些方法，通过这些方法教育者可以帮助这些学习风格更好地适应，尽管所有这些风格更偏重对学习实践的表述而较少注重学习理论的表述。

After that, the article expounds how the social labor value theory overcomes the theoretical hard nuts in the financial accountings:(1) it has solved the issue of conformity between the production domain and accounting domain by holding that the social labor creates the value, which decides that the domains of production and accounting should be extended to cover the tertiary industry;(2) it has solved the issue of the valuation standards in the economic accounting by holding that the theoretical value should be converted into the actual value and that only when the price of production is used as the valuation standards can the financial accounting and economic accounting have a true valuation basis;(3) it has solved the issue of creation and distribution of surplus value and explicitly points out that the power of science and technology determines that the surplus value comes mainly from the materialized labor. Only when we have a clear understanding of this point and have realized that the value of product is created jointly by the materialized labor and the laborer can we straighten out the relationship in the distribution of earning inside the enterprise and understand that the distribution on the basis of contributed capital is a reasonable choice at present.

其次，着重阐述了社会劳动价值论如何解决经济核算中的理论难题：一是解决了生产范围与核算范围的统一问题，认为社会劳动创造价值，决定了生产范围与核算范围都必须扩大到第三产业；二是解决了经济核算的计价标准问题，认为必须从理论价值转化为实际价值，用生产价格作为计价标准，才能使会计核算和经济核算真正具有计价基础；三是解决了剩余价值的创造与分配问题，并明确指出，科技的力量决定了剩余价值主要来自于物化劳动，只有认清这点，承认企业的产品价值是物、活劳动共同创造的，才能真正理顺企业的利益分配关系，才能理解按资分配是现实合理的选择。

At first, in this paper the national and international literature of team and team motivation is summarized. Secondly, based on the analysis of theoretical scientific research personnel and team, the teamwork motivation model is built, and it is achieved that teamwork improves the team output. Later,we lead the reputation that is regarded inexplicit incentive into the scientific research personnel"s utility function, establish a model of their reward, analyze the parameter of reputation"s effect to factor in the contract. After that, it analyses traditional training object selection and whole training object selection among the scientific research team to draw the conclusion that the traditional training object selection has obvious limitations and the whole training has evident advantages. In the end, based on the theoretical study of the psychological contract, we can obtain the effective paths of forming psychological contract among the scientific research team.

Based on modern option pricing theories,Black-Scholes and Merton option pricing model are used to study the pricing of the structured products,and its design,characteristics and risk are studied respectively.Based on Black-Scholes and Merton option pricing models,I also use the checking method to estimate the parameters of the model following real prices data,And calculate the theoretical price.Then,I compare the real and theoretical prices of the two pricing models.The results show that the effects of the Merton option pricing model are superior to the Black-Scholes option pricing model.Moreover,It shows that Hong Kong stock prices are also affected by the instant messages,and the jump phenomenon may exist in Hong Kong stock market.
