Abstract--Traditional mathematical receptor models can be broadly classifiedinto two categories: chemical mass balance ( CMB) and multivariate Technique ( MVT) . The application of CMB is limited by the requirement of knowing the signatures of sources to be resolved. MVT based on the factor model has a suspect of " artificial data",because the solution derived from the algorithm of eigenvectors is not unique or with too great uncertainty. Elemental tracer system developed recently expands the use of receptor modelling from city scale to region scale, but it has notbeen applied widely becauee it depends too much on experience.This article discusses systematically some key problems of modern receptor modelling. 传统的数学受体模式可概括地分为两大类,即化学质量平衡法(CMB)和多元技术(MVT),CMB由于要求已知所求源的成分谱。从而在应用中受到限制。MVT以因子模式为中心,由于因子模式的本征向量解法求解不唯一或称误差太大,使得MVT给人一种人造数据的印象。近年来,元素示踪体系将受体模式的应用范围从城市尺度扩展到区域尺度,由于该体系经验性太强,未能得到广泛的应用。本文针对现代受体模式中存在的一些关键性问题作了系统的评述。 With reference to the method of appraising the tri-factor model of American stock market by means of Fama and French , this paper studies the assets pricing model of China's stock market. In China's stock market, there is no book market effect, but a certain system risk factor relevant to the scale plays an important role in the stock pricing. On the basis of this, appraised has been the factor model of China's stock pricing. 参照Fama和French鉴定美国股票市场三因素模型的方法 ,研究中国股票市场的资产定价模型。在中国股票市场 ,账面市场效应并不存在 ,但与规模相关的某种系统风险因素在股票定价中起到了重要作用。由此鉴定出中国股票定价的二因素模型。 Entrepreneurs have various needs, and the incentive ways for entrepreneurs should be various. Five entrepreneur's needs are analyzed. After comparing some incentive ways for entrepreneurs, the authors present a series model to design comprehensive incentive schemes, including the factor model to determine incentive levels, the combination and proportion models and a general procedure model to design incentive schemes. 经营者有多种需要,对经营者的激励也应有多种不同的方式和方法。分析了经营者的5种需要,比较了激励经营者的多种方法的利弊,提出了设计经营者综合激励方案的系列模型,包括确定综合激励水平的因素模型、组合及比例结构模型和设计激励方案的一般程序模型。
