Study on Three-layered Grid Conceptual Prototype Using Ecological Network Computing Environment

Next generation grid systems where the emphasis shifts to distributed global collaboration, a service-oriented approach and information layer issues exhibit a strong sense of automation. Requirements for these systems resemble the self-organizing and the healing properties of natural ecosystems. Some key ecological concepts and mechanisms are introduced into the design for the third generation grid computing architectures by inspiration of this resemblance. Also, an Ecological Network-based Computing Environment (ENCE) platform is designed in this paper. Based on the ENCE platform, a grid-computing model of three-layered grid conceptual prototype that embeds the ENCE layers is presented from the viewpoint of implementation. The implementation model should be useful to the design of the third generation grid systems.

3-D Design and Numerical Simulation of Two-Phase Flow in the Laser Rapid Prototyping Coaxial Powder Delivery System

The metal powder direct and rapid prototyping technology is one of the most developing methods in the laser rapid prototyping technique. The coaxial powder delivery system is the key technique. The purpose of this paper is to introduce a new type of coaxial powder delivery system and simulate the metal powder and shield gas flow in the powder nozzle. 2-D and 3-D model of the new coaxial powder delivery system are established. Then gas-solid two-phase flow model and the k-ε turbulent model are selected to simulate the flow of metal powder in powder nozzle. The Euler-Lagrange method is used in the simulating computation. The results show that the new coaxial powder delivery system has stable performance, uniform powder flux, high cooling efficiency, and long useful life.

任是无形也动人——试析<聊斋志异>的穷而后幻

《聊斋志异》是蒲松龄的孤愤幽怨之作。作品将狐仙鬼魅幻化成美女，表达蒲松龄单方面的落魄书生幻想。这是作者在“不解怜才”的现实世界屡受生活颠踬之后渴望展现自身价值而产生的穷而后幻的自我疗救。     

习语翻译的归化与异化认知限定

英汉习语都包含着丰富的文化信息,在习语翻译过程做到归化与异化的辩证统一,即有利于源语文化向目的语文化渗透,又有利于译文符合译语的语言习惯。归化与异化的程度和范围应受人类认知能力的影响。本文基于认知语言学的理论,从认知范畴化理论视角探讨习语翻译的归化与异化的关系,认为英汉习语的翻译不仅仅是语言符号的转换,更主要的是认知范畴的移植。
