摘要该文讨论了超声波声速测量实验中出现的几个问题，并通过数值计算，说明了超声波能量随距离的增大而形成的衰减趋势，并对影响测量精度的因素进行了讨论。
The flowfield over low - drag and long - range projectile with small attack angle is numerically studied from transonic to supersonic velocity . it provides basic work for aerodynamics characteristic of this projectile and for lateral jet interaction flowfield , and it shows this projectile can decrease drag . zonal method is tried to compute flow over projectiles and results is satisfied , but computation is much slower
系统研究了低阻远程弹丸在小攻角状态，低跨声速、高跨声速和超声速时的非对称绕流流场，为该弹形气动力研究提供理论指导并为弹丸侧喷流研究奠定基础，结果显示低阻远程弹丸外形具有优化绕流场、减小空气阻力的特点。
