茶旅融合与互动发展:模型建构与效果测度——基于浙江省的实证研究

茶旅融合与互动发展是茶产业及旅游产业发展的内在需求,对于破解茶产业利润增长瓶颈具有重要意义。本研究以浙江省为例,在产业融合理论及耦合理论指导下,构建了包含茶旅融合动因、融合路径、融合效益的机理模型,并通过构建耦合函数模型对浙江省茶旅融合情况进行实测,发现浙江省茶旅产业均处于增长阶段,但旅游产业的发展比茶产业更慢,且茶产业对旅游产业具有明显的引领作用,此外,茶旅融合程度也从失调状态发展到耦合协调状态。最后,本文针对如何进一步促进浙江省茶旅融合发展,突破茶产业的发展难题,实现茶产业转型升级,从产品创新、加强宣传、完善配套、培育一体化品牌4个方面提出相应的对策和建议。

大清河流域产汇流特性变化趋势及影响因素

以大清河水系紫荆关流域和阜平流域1956-2005年的暴雨洪水资料为基础,利用Mann-Kendall秩次相关检验法研究了流域内产汇流特性的变化规律及其影响因素.结果表明:次洪量和径流系数呈下降趋势,洪峰滞时和汇流单位线峰现时间呈上升趋势.降水量的变化对大清河流域的产汇流规律有直接的影响,但下垫面的变化在一定程度上影响了流域的产汇流规律,引起产汇流特性的变化.     

Feature of Iteration Convergence in Concurrent Design

A parameter, proportion of all work on every task in each stage, is introduced to build a new WTM. Based on this new WTM, this paper deeply analyzes the relationships between the eigenvalue and the convergence rate of the total work, and the relationships between the eigenvector and the total work. By comparative analysis between the existing WTM and new WTM, it is investigated that this parameter causes the increasing total work and decreasing convergence rate, and the existing WTM is just a speciality when this parameter becomes the maximum. Finally, the generality of the new WTM is tested by the design process of the camera.     

Feed-forward Neural Network Based onGaussNewton-NL2SOL Algorithm and Its Application

Though the feed forward neural network based on GaussNewton algorithm and its derivation will converge with order two, it is only effective toward little residual problem. In order to solve the little and large residual problems at the same time, NL2SOL algorithm is introduced and combined with the GaussNewton algorithm so as to form a feed forward neural network based on GaussNewton-NL2SOL algorithm. The application shows that this neural network can solve the residual problem properly and the convergence and stability of it performs well.     

Effective Method to the Renormalized Finite Quantity of the Meson Loop Propagator (I)

By using the Lorentz invariable coupling model of interaction between neutral meson and nucleon (antinucleon), Feynman convergence integral method is often used to deal with the finite quantity of one-loop correction scheme. On the basis of analyzing, discussing and researching the method, a new method is found. That is the large momentum integral limitation method. With the effective method, we obtain the integral convergence formulation for the finite quantity, by deducting-dimensionally calculating the finite quantity gained after renormalizing the meson loop propagator.
