But in recent years inflation has become more threatening. Worries therefore grow that the robust economy may slump due to the overwhelming macro-economic controls. How should China rein in inflation and at the same time hedge against economic freefall? What differentiates the country’s macro-economic controls in recent years from those in the past? Liu Shucheng and Zhang Xiaojing, researchers with the Institute of Economics under the Chinese Academy of Social Sciences, gave their opinions in the following excerpts:展开更多

The country’s new president-elect was born to a poor family in south South Korea but ascended to the top spot of the country’s largest conglomerate company. He went on to become mayor of Seoul and is now about to become the country’s next president.展开更多

For the specified volumes of the body, fin and heat source, the constructal optimizations of the body with single and multiple inner heat sources are implemented. The entransy-dissipation-rate-based equivalent thermal resistance(ETR) is minimized in the optimizations. It shows that for the helm-shaped body with multiple inner heat sources, there exist an optimal ratio of the heat source distance to the radius of the extended fin and a twice optimal radius ratio of the centre fin to the extended fin which lead to the double minimum dimensionless ETR. Comparing the optimal result of the body with helm-shaped fin with that with annular fin, the radius of the centre fin and the distance between the heat source and the center of the body are decreased, and the ETR is decreased by 9.57%. Essentially, the temperature gradient field of the helm-shaped body is more homogenous, and its global heat transfer performance is improved.展开更多
