1·Finally, eliminate the stain and scrub corrosion, must remove the part when necessary, especially the rolling bearing, the centre of gravity after clean assembly.
最后，消除机体污渍，擦洗锈蚀，必要时须拆下机件，特别是滚动轴承，清洗干净后重心组装。
2·From the angle of the modeling, sunray resembles a cone and its centre of gravity below halfway, which gives our visual perception stability and comfort.
从造型角度，其上细下粗，重心靠下，给人的视知觉以稳定感和舒适感；
3·"CENTRE OF GRAVITY", "FRONT" and "BACK" signs must be clearly marked externally for uneven loads and bulky items.
在不均匀装载和大件物品上，“重心”，“前”和“后”标记必须被清楚标明。
4·Two circuits exchanging for takes advantage of that problem is that organization owes the centre of gravity that space designs under area the ground location.
两条线路地换乘问题是组织该地域地下空间设计地重心地点。
