查询词典 basic point

According to the basic equations derived under the two assumptions by Harold Lauffer—(1) the energy head of every point of a vertical section remains constant,(2) the flow lines are concentric circular arcs,this paper qives a comprehensive deduction of curvature effect in the characteristics of free overflow of round-crested spillway.118 runs of experiments of three round-crested spillway models of different size have been conducted by the author.

本文根据劳弗尔氏在两项假定[(1)垂直测线上各点所含能量为常数，(2)流线呈同心圆弧]下所导得的基本公式，作了详细的补充引伸，得出圆顶壩自由溢流时各项水力特性中的曲率影响计算公式。作者曾进行了大、中、小三个圆顶壩模型的试验共118组，试验成果基本上和导得的计算公式相合致。文中并根据试验资料制定了一些经验公式，应用时可更简便。

A method to calculating maneuver for special point maneuver strategy is developed based on the facts that are single objective of every maneuver and tiny correction for orbit inclination and right ascension of ascending node. The basic idea of the method is disassembling calculating for phasing and orbit plane correction, and the equation for calculating maneuver is derived.(2) A method for determining the optimal collision avoidance maneuver is developed, and the two phasing orbits strategy is developed to avoid collision with debris.

1研究了远距离导引的特殊点变轨策略，针对特殊点变轨策略每次机动目标单一和轨道面修正为小量的特点，提出了将轨道面内调相与轨道面修正分解计算的策略，推导了采用高精度轨道模型的调相和轨道面修正机动计算公式；(2)研究了远距离导引段飞行器规避空间碎片的机动问题，提出了一种双调相轨道机动策略，并给出了碰撞规避机动的计算公式。
