When designing the attitude control system of spacecraft, it is necessary to take account of the sunlightpressure disturbance torques under various sunlight incident conditions.
在设计航天器姿控系统时，需要充分考虑各种光照条件下航天器所受到的太阳光压干扰力矩。

Some are swept back by radiation pressure from sunlight to create straight dust streaks.
其中的一些碎片受阳光的辐射压力作用形成与周围星尘不同的直条状。

They draw their energy from sunlight (the reflected light exerts a small pressure on the sail, driving it forward) and therefore need no fuel.
