1.moving in the same orbital or rotational direction as another astronomical body
1.If accretion takes place in eccentric orbits as well, the rotation will be prograde and of the right order of magnitude.
如果吸积发生在偏心轨道，则自转将是正向的，且快慢也合适。
2.If the patients have prolonged atrioventricular conduction, the PJ interval may be shortened by the pathway prograde conduction.
在正路传导异常时旁路前传能缩短延长的PJ间期；
3.Irregular moons with prograde orbits are shown in light grey, those with retrograde orbits in dark grey.
而不规则卫星中，浅灰色为顺行，深灰色为逆行。
4.Prograde orbits are more vulnerable than retrograde ones.
因此顺行的轨道会比逆行轨道更加脆弱。
5.A surprise in this computation is the presence of prograde motion in the fundamental mode.
一个意外的计算结果是在基本型中出现前进运动。
