从广义水环境承载力定义出发,建立水环境承载力评价指标体系;采用层次分析-熵值定权法和向量模法对武汉市水环境承载力进行评价,该定权方法采用层次分析法确定权重,同时又引入熵值法对权重进行修正,在一定程度上减少了主观影响。该方法使评价指标的赋权达到主观与客观统一,对水环境承载力的量化更加准确与合理。该方法构造简单,便于实现计算机编程,所以应用较为简单、方便。以武汉市为例,综合考虑资源环境以及社会经济发展,建立了一套指标体系,利用向量模法对指标进行量化,结果表明武汉市2006~2010年水环境承载力逐年增大,由0.129 3增长到0.241 1,表明近些年武汉市水资源、环境与社会经济的发展...

A detailed unsteady numerical simulation has been carried out to investigate the shock and unsteady flow in the low pressure (LP) rotor in a 1+1/2 counter-rotating turbine (vaneless counter-rotating turbine (VCRT)). Through analyzing the distribution of static pressure and Mach number etc. in the VCRT, it can be found that, when the outer-extending shock of high pressure (HP) moving from one LP rotor leading edge to the next, a bow shock appears upstream of the LP rotor, and a normal shock produces at roughly 70% axial chord on the suction surface of LP rotor, and between the bow shock and nor...
