trajectory GREGMAT

Objective:To observe clinical effect and complications of treating ureterolith through aerodynamic trajectory lithotrity by ureterorenoscope(URS).

观察经输尿管肾镜行气弹道碎石治疗输尿管结石临床疗效及并发症。

Conclusion: Under ureter mirror barometric pressure trajectory lithotrity security.Damages slightly.The effect is obvious.

结论输尿管镜气弹道碎石术安全,损伤小,效果确切。

The ACR "rifles" used smoothbore barrels to fire single or multiple flechette per round, rather than bullets, to provide long range, flat trajectory, and armor piercing abilities.

炮弹（抛射）拥有稳定外形，比如带尾翼箭状或球体，以此减小发射时震动。

Because arc length of trajectory is regarded as the variant in geodesics based method, it possesses the advantages of non-time based trajectory planning at the same time.

本文基于测地线轨迹规划是以轨迹弧长作为参考变量，因此它还具有非时间参考机器人轨迹规划优点。
