Hedonic价格理论分析

传统经济学的价格理论分析的是同质产品的价格,而Hedonic价格理论分析的是差异化产品的价格。Hedonic价格理论指出产品的价格是由组成产品的各个特征的价格构成,产品的特征对应的价格就成为特征价格。文章对He-donic价格理论进行了系统的分析和总结,为该理论的实证研究提供了理论依据。

Adaptive merit function in SPGD algorithm for beam combining

The beam pointing is the most crucial issue for beam combining to achieve high energy laser output. In order to meet the turbulence situation, a beam pointing method that cooperates with the stochastic parallel gradient descent(SPGD) algorithm is proposed. The power-in-the-bucket(PIB) is chosen as the merit function, and its radius changes gradually during the correction process. The linear radius and the exponential radius are simulated. The results show that the exponential radius has great promise for beam pointing.
