Some projections show areas accurately but distort distances or scales , for example ; others preserve the shapes of countries but misrepresent their areas .
比如,一些投影准确地显示了区域,但是扭曲了距离或比例;其他投影保留了国家的外形但是代表的区域不对。
But this was enough to tip the scales , especially in highly competitive events where a photo finish decides the winner .
但是这已经足以让天平倾斜了,尤其是在那些谁胜谁负需要靠照片来判断的高水平竞技赛事上。
The kinds of scales involved still mean it would only be detectable in the most sensitive instruments we have such as the gravitational wave detectors looking for the ripples in space-time caused by violent cosmological events such as the collision of two black holes .
