The only incidents which occurred to mar the precision of this remarkable concentration were the loss by u-boat attack of three ships in convoy . 这次罕见的船队大集中，体现了高度的准确性，唯一美中不足的是，船队有三艘船只被潜艇击沉。
Of all the aerodynamic parameters required in stability and control analysis, the hinge-moment coefficients are most difficult to determine with precision . 进行稳定性和操纵性分析所需要的全部空气动力参数中，铰链力矩系数最难准确地确定。
We can measure with even more precision the percentage of items that fall within specific ranges under a symmetrical, bell-shaped curve like the one in figure 4-3 . 对于图4-3那样的对称正态分布曲线，则能更精确地算出落在某个特定范围内的单位数所占百分比。
