轨道速度 meaning in English
circular velocity
orbital speed
orbital velocity
Examples
- Orbital velocities in spiral galaxies , instead of declining with increasing distance from the galactic center , flatten out to a constant value , as predicted by mond
螺旋星系中的轨道速度并不会随著离开星系中心的距离增加而不停降低，它会平缓下来成为一固定值。 - Genzel ' s team has measured the orbital speed of gas clouds within 11 of these systems , giving the first unambiguous measurement of the mass of galaxies in the early universe : greater than 100 billion solar masses , as hefty as the biggest galaxies in the present - day universe
甘泽尔的团队已经在11个这样的系统中，量测到气体云旋转的轨道速度，因而首度清楚得知早期宇宙中星系的质量：大于1000亿个太阳质量，与现在宇宙中最大的星系相同。 - Second , the imaging model built here has taken into account the tilt modulation , the hydrodynamic modulation , and current modulations of radar cross section . consequently , it has realized the imaging simulation of four kinds of wakes with the same imaging model . third , the orbital velocity of ocean wave was considered as the basic dynamic factor , and the imaging model calculates the influence on raw data by the wave m ovement according to the orbital velocity
该模型的主要特点是： ( 1 )它采用了三尺度复合表面模型的思想来计算海面的电磁散射，考虑了中等尺度波对纹波的进一步调制作用，弥补了传统双尺度模型的不足； ( 1 )它考虑了海浪的倾斜调制作用、流体动力调制作用和流场对雷达截面的调制作用，实现了用统一的仿真模型对四种舰船尾迹特征进行成像仿真； ( 3 )它把海面长波的轨道速度作为基本的动态成分，并依此来考虑海面运动对sar回波信号的影响。
