查询词典 acceleration of convergence

With the increasing of the overburden layer thickness or the dam height, the maximum value of response acceleration in dam body assumes gradually decrease, and its characteristic distribution is uniformization, and the response acceleration of the dam slopes decrease remarkably, and response acceleration of the dam top is less than the dam bottom.With the decreasing of the overburden layer thickness, the dam foots and their nearby soil response acceleration get increasing.

Government transfer payment is an important policy instrument to coordinate regional economy. This paper measures and analyzes the convergence test of income during 1995-2004, and analyzes the relationship between transfer payment after tax-sharing system reform in 1994 and regional economic convergence through econometric analysis. It concludes that income has neither absolute convergence nor conditional convergence in the nationwide. The overall transfer payments did not meet the goal of narrowing income gap, especially in the central and western regions.

Based on the measurement and calculation of Chinese agricultural Total Factor Productivity using the non-parameter Data Envelopment Analysis and Malmquist productivity index approach,the paper has tested the convergence hypothesis of the agricultural TFP growth in China for the transformational period(1978~2005),and this includes the σ convergence,unconditional β convergence and the conditional β convergence.

在利用非参数的DEA曼奎斯特生产率指数方法对中国农业全要素生产率进行求解的基础上，论文运用经济增长收敛理论对农业TFP(Total Factor Produc-tivity)增长在1978~2005年转型期的收敛性情况进行检验，这包括从σ收敛、绝对β收敛到条件β收敛的全面检验。

So the convergence rates of space convergence clubs generally are beneath the convergence rates of time convergence clubs.
