空间导叶设计新方法

本文以空间势流理论为基础,提出了一种常见空间导叶结构设计新方法,丰富了导叶二元设计内容。新方法解析出空间轴面流动速度分布特点及流动函数,保证导叶有关几何参数的计算更为可靠精确,为改善导叶设计理论及程序作了有益探索。

地震过程中作用在刚体重力坝的水压力计算

本文基于空间势函数积分问题发展了边界积分方程模型,并将其转化为围绕目标单元的线性积分,此模型可以用于地震过程中作用于刚体重力坝表面水压力的计算。

Discussion on the new space of strategic development and function of Hengsha,Shanghai

Integrating various resource advantages including location, land, coastline and waterway, Heng- sha, Shanghai will be the new space of strategic development in the future （especially after 2020）. Inspired by marine economic development and continual establishment for new strategic space of coastal cities, in this pa- per we will take the strategic development direction of Hengsha new space into consideration when enlarging on the positioning of the new development space in Hengsha, which includes international logistic center （free har- bor and logistic transshipment center）, modem port industry, high-end services, tourism, leisure, and recre- ation and ecological village in downtown area.
