居民收入差距过大对中国经济增长的影响

目前,中国的基尼系数已经达到0.48,超过了收入差距过大的警戒线。居民收入差距过大会从三个方面影响中国经济的增长:通过减少消费需求和投资需求来减少有效需求;影响教育投资和人们从事科研的积极性,影响经济发展的动力;容易导致社会不稳定,影响经济发展的外部环境。

Dynamic Responses Analysis of a Building Structure Subjected to Ground Shock from a Tunnel Explosion

Dynamic responses of a multi-storey building without or with a sliding base-isolation device for ground shock induced by an in-tunnel explosion are numerically analyzed. The effect of an adjacent tunnel in between the building and the explosion tunnel, which affects ground shock propagation , is considered in the analysis. Different modeling methods, such as the eight-node equal-parametric finite element and mass-lumped system, are used to establish the coupling model consisting of the two adjacent tunnels, the surrounding soil medium with the Lysmer viscous boundary condition, and the multi-storey building with or without the sliding base-isolation device. In numerical calculations , a continuous friction model, which is different from the traditional Coulomb friction model, is adopted to improve the computational efficiency and reduce the accumulated errors. Some example analyses are subsequently performed to study the response characteristics of the building and the sliding base-isolation device to ground shock. The effect of the adjacent tunnel in between the building and the explosion tunnel on the ground shock wave propagation is also investigated. The final conclusions based on the numerical results will provide some guidance in engineering practice.     

面对这条小路

合上了书本,揉了揉困乏的眼睛,漫步走进屋后那片山林,那片接近过几次却未曾深入探访的山林。一条弯弯曲曲的山林小路,是名副其实的羊肠小道,铺着落叶。这是一条我不曾走过的路,一条不知道终点的路,我
