This method is universal to every kind of black holes. By means of thin film model, the entropy density at every point of the event horizon is calculated first, then the total entropy is obtained through integration.展开更多

This paper makes a nonsymmetrical error correction model for the re-loan rate and inter-bank rate,to research the dynamic transmission mechanism of the relation of these interest rates. The significant nonsymmetrical relation is found between the two interest rates and it is the nonsymmetrical relation that has great influence in the transmission effect of the interest rate policy,furthermore,the economics explanation of the nonsymmetrical relation is the arbitrage of the banks and the single direction of the re-loan rate.展开更多
