Adapting to the high variation environment in data grid,a data replica replacement algorithm based on value model is proposed and the arithmetic to calculate replica value is introduced.The algorithm is used on data replica replacement.When there is not enough storage space during replication,the replica whose value is the least will be deleted.This algorithm can improve and maintain a high overall throughput of grid jobs that access files in a data grid.Experimental results show that the proposed algorithm can obtain better performance for grid task to access data replica.

A finite-state Markov channel model representing Rayleigh fading channels was introduced.A methodology of selecting signal-to-noise thresholds and the total number of states were discussed based on the analysis of the steady-state probability.And the transition probabilities between states and error probabilities were calculated with the given fading characteristic parameters such as level crossing rate.The validity and accuracy of the model are confirmed by the simulation.

The article analyses the basic nature、characteristics and historical meanings of social transformation across the globe.It is pointed out that social transformation is the process from non market economy to market economy in economic field,from centralization of state power to democracy in political field,from traditional culture to modern culture in culture field.At last,the article further discusses the porticularity of social transformation in China.
