查询词典 ballistic missile

In order to improve penetrativity of hypersonic missile and enable air-launched hypersonic cruise missile to penetrate with skip trajectory, a new approach of generating positive angle of attack during reentry phase of trajectory was proposed. Some key parameters of realizing skip trajectory were found out, and the effects of these parameters on ballistic performance were discussed.

为提高高超声速导弹的突防能力，使常规布局空中发射的高超声速巡航弹能采用跳跃式弹道突防，采用了在导弹再入段附加相应的正攻角产生气动升力的方法，找出了实现弹道起跳的关键参数，讨论了这些参数对弹道性能的影响。

For missile flight test, telemetering data and exterior ballistic measuring data arethe basis of precision and reliability analysis.

在导弹飞行试验中，遥外测数据是进行精度和可靠性分析的依据。

A theoretical analysis of local damage in a thin ductile tube hit by a flat-nosed missile laterally is developed to predict local failure due to plugging by the beam-on-foundation model. The effect of internal press was considered, and differential equations was obtained which can predict the ballistic speed of the missile which impact the tube filled with water. It can be solved by Runge-Kutta method.

采用地基梁模型对平头弹体侧向冲击钢管的冲塞型破坏模式进行了理论分析，考虑了充压情形下内压的影响，导出了钢管在冲击过程中的运动方程，可以用龙格—库塔法进行数值求解来确定弹体冲击充液压力管道的弹道极限速度。

Methods: Five patients with parkinsonism or dystonia were assigned to general anesthesia using an modified endotracheal tube.

本实验依照人体实验之相关规定进行，五位患有帕金森氏症或肌张力异常的病人接受神经立体定位手术。
