基本解释

Scanner errors include pixel interval error, horizontal-to-vertical proportion error and starting position error.
扫描仪误差包括像素间距误差、像素间距横纵比误差及扫描起点误差等。

In order to solve the problem, a method of conjugate gradient optimization was applied to find the horizontal error angles.
为了解决这一问题，提出了采用共轭梯度优化的方法求解水平修正参数，进而修正由坐标系不水平带来的误差的方法。
As pointed out here*, this seems bold, since the horizontal error on the points (the bin width) is five times bigger than this.
如下所指出的*，这一论断似乎很大胆，因为数据的横向不确定性（误差棒的宽度）大约是这个数值的5倍以上。
