A study on the dynamic comparison of logistics industry’s correlation effects in China

As a basic and strategic industry,the logistics industry is closely linked with and influenced by other industries while influencing them.It plays an irreplaceable role in ensuring smooth operation of the national economy and satisfying the demand of consumers.Its development level directly affects that of the national economy.Based on the analysis into input-output tables from 1997 to 2010,the association effect between the logistics industry and its related industries is measured and the dynamic degree of influence logistics industry exerts on relevant industries at the different periods is observed,both of which enable an objective judgement to be gained in identifying the status of logistics industry in the national economy.The main conclusions are as follows.(1)The status of logistics industry remains to be further promoted.(2)The logistics industry turns into one with“low added value and strong leading force”.(3)Industrial logistics is the main trend while logistics of service industry change.(4)The logistics industry is closely linked with the second industry.The author then puts forward countermeasures and suggestions:(1)Develop Third-Part Logistic in order to promote the socialisation and specialisation level of logistics distribution;(2)Speed up the development of electronic business logistics,set up reasonable layout of transportation infrastructure and build entitative logistics network;(3)Accelerate the logistics informationization and standardization and improve management and service levels of logistics enterprises.

Comparison and Examination of Dynamic Frameworks of IAP and OSU AGCM

A brief description of the dynamic framework of the IAP 2-L AGCM (referred as 'IAP DF') is presented in contrast with the corresponding 'OSU DF' and preliminary comparison and examination of the IAP DF and the OSU DF with the aid of numerical experiments using a set of baroclinic Rossby-Haurwitz wave initial conditions is performed.The results of the numerical experiments show that both the IAP DF arid the OSU DF are long-term computational stable and are able to simulate the fundamental behavior of the Rossby-Haurwitz wave under the limitation of 7.5 minutes time interval. In the respect of the prediction of the large-scale wave, the IAP DF is better than the OSU DF, however, the OSU DF gives better predictions of zonal mean status than the IAP DF does. Another important contrast is that the level of small-scale noise of the IAP DF is higher than the OSU DF, on the contrary, the damping effect of the OSU DF on large-scale vortex field is stronger than the IAP DF.

Comparisons of Criteria for Analyzing the Dynamical Association of Solutes in Aqueous Solutions

How to determine accurately the association states of solutes in aqueous systems is of fundamental importance in a variety of chemical, physical, and biological processes, We apply four widely used criteria to analyze the dynamic association processes of solutes, e.g., amphiphilic molecules, and to find the inappropriate selections of representative sites on solutes in these criteria may bring about appreciable influence on the estimation of dynamic association behaviors such as unrealistic packing radii and even misleading packing structures. It would be better to select dynamically representative sites on solute molecules based on the characteristic of solute associations. Our detailed discussions give a guide on how to determine an appropriate criterion to accurately analyze the association behaviors of solute molecules in aqueous solutions.

Validation of CFD-DEM simulation of a liquid-solid fluidized bed by dynamic analysis of time series

Liquid-solid fluidized beds(LSFB)modeling validation is crucial for establishing design rules and monitor-ing tools.However,it generally relies on comparing global variables,which overlook dynamic features that influence reaction outputs.This work aims to implement time series analysis tools to compare Radioactive Particle Tracking data with a simulation consisting of Computational Fluid Dynamics cou-pled with Discrete-Element Method.Experiments have been performed in a pilot-scale LSFB of calcium alginate spheres fluidized with a calcium chloride solution.The Diks'test indicates that the simulation can capture the LSFB behavior.It also allows diagnosing flow regime transitions from the simulation.Trends of solid dispersion coefficients and mixing times predicted by the simulation are in good agreement with the experiments.
