只要有一层玻璃的形状差了仅仅千万分之一米，望远镜的精确度就会大打折扣。
If a glass layer's shape is off so much as a fraction of a micron, the scope's precision takes a mighty blow.
理论和实验结果表明，利用所述方法对等高线进行数据简化，方法简捷，精确度高，而且能够保留原等高线的形状结构特征。
The theory and experiment results show that the simplifying method is easy and accurate, and shape construction feature of original contour can be retained.
