通过风洞试验研究了上海电视塔上下球体的风压和气动力．结果表明：两球体的压力分布均不同于光滑圆球，阻力比超临界光滑圆球大得多． The wind pressure and aerodynamic forces of the upper and lower spheres of Shanghai TV Tower were studied by wind tunnel tests. The results show that the pressure distributions of the two spheres are different from those of the smooth spheres, and the resistance is much larger than that of the supercritical smooth spheres.
