The official emblem, designed by Josep Maria Trias from Barcelona, depicted a dynamic human figure in a stance that suggested someone jumping an obstacle (which consisted of the five Olympic rings) and the simple, gestual lines reduced the characterisation of the figure to the head (in the blue of the Mediterranean), the arms (the yellow of the sun and wide open in sign of hospitality) and the legs.

极具民族特色的&三太极&应运而生，其中的黄、红、蓝三种颜色的色带仿佛运动场上的跑道，代表天、地、人三位一体的和谐统一，三色条带外旋象征世界的繁荣与进步，内旋则寓意各国运动员的团结和友谊。

We then add boundaries delineated forward/backward facing reflected shock, Mechanical equilibrium, M2=1 and reflected shock strong/weak separating conditions on the (M0,q1) map of shih(2004). This is followed by systematically investigating multiply possible three shock theoretical solutions of steady Mach reflections in perfect triatomic gases. Pressure-deflection shock polar solutions are used to help illustrate different solution behaviors of these theoretical three-shock solutions. M0 is flow Mach no. upstream of incident shock, M1 is flow Mach no. downstream of incident shock, M2 is flow Mach no. downstream of reflected shock,q1 is flow deflection downstream of incident shock.
