| 摘 要： | 本文对高速空气射流在受限约束下的动力学行为进行了实验研究。通过流动可视化揭示了高速空气射流在单筒和同心筒发射筒底部滞止、反转、而后向上绕经航行体或同心筒间隙向上喷入水中的演化过程。主要观察了单筒底部有无导流锥、同心筒三种间隙在不同压比和不同流量下的气水两相流态,并测量了航行体与发射筒的壁面压力分布。给出了航行体壁表面压力的动态变化规律,和沿轴向的分布规律。

| Abstract: | The rapid development of bilateral trade between China and ASEAN makes both sides become mutual important partners. The similarities and differences in economic development and industrial structure between China and ASEAN lead to the complementarily and competitiveness. This study elaborates the status of bilateral trade, analyzes the causation of resulting the complementarities and competition and the impacts on bilateral trade. Finally, the impacts on the future development trends have been proposed. |
