查询词典 elasticity of substitution

The results show that although economic growth in the northwest region as the whole has been physical capital-driven, elasticity and contribution rate of human capital in each province has been relatively high, indicating the spillover effect of human capital These findings suggest that effectively and steadily speeding up human capital accumulation while increasing capital investment may enhance the level of economic development in the northwestern China, thus reducing the disparity between this region and the eastern region.

结果表明，虽然西北地区的经济增长总体来看是资本推动型的，但各省区人力资本的产出弹性和贡献率较高，而且人力资本的溢出效应较为明显，此外，各省区间人力资本对经济增长的贡献率有较大差别。据此作者认为，在中国经济增长方式转型期，除加大物质资本投资力度外，有效、持续地加快人力资本积累，可以更快地提高西北地区的经济发展水平，从而缩小该地区与东部地区的差距。

According to that characteristic and based on the differential equation of the deformed surface of the orthotropic plate, with one principal direction size fixed, changing another principal direction size linearly, maintaining elasticity coefficient the same as in the first principal direction and Poisson ratio equal to the geometric mean of two principal Poisson ratios, the original orthogonal plate is equivalent to an isotropic plate. Results obtained show that the deflections of the equivalent isotropic plate are the same as the deflections of the original orthotropic plate at the corresponding points, the forces of the correspondent points have simple relations.

根据这一特性、从正交各向异性板挠曲面的偏微分方程出发，保持一个主方向尺寸不变，另一主方向的尺寸做线性缩放，保持弹性模量与第一主方向相同，泊松比取2个主方向泊松比的几何平均值，将这类正交各向异性板等效为一块各向同性板；通过分析得到：各向同性板任意点的挠度就是原正交各向异性板对应点的挠度，各对应点内力之间存在简单的比例关系，该文的方法将为工程技术人员提供方便，同时可以更加直观的认识正交各向异性板的受力。
