When the IAU's value for k is used to calculate these times, they must be corrected to accommodate low valleys or high mountains along the Moon's limb. The calculation of these corrections is not trivial, but is necessary, especially if one plans to observe near the path limits (Herald 1983). For observers near the central line of a total eclipse, the limb corrections can be more closely approximated by using a smaller value of k, which accounts for the valleys along the profile.

当IAU的K值被用来计算这些时刻，他们必须纠正并使其符合月球边缘的低谷和高山，这种修正并不是不重要的，相反是很必要的，特别是计划观察靠近极限路径时（Herald 1983），对于靠近全食中心线的观测者来说，在使用更小K值的情况下，边缘修正会被更准确地近似，这个K值代表山谷沿着轮廓。

With the character of CVC roll curve, the strip thickness distribution, rolling pressure distribution and pressure between rolls along transverse direction are calculated, by using the model of the real roll crown distribution and the character of the antisymmetry of mills. The results are in good agreement with production data.

根据CVC轧辊辊形的特点，采用实际轧辊凸度分布模型，并利用轧机的反对称性质，计算轧机垂直中心线一侧的板断面厚度分布、轧制力分布、辊间压力分布等，提高了板形计算和辊间压力计算的精度，模拟计算结果与现场数据相符。

It respectively constructs quasi projection-separation facet sets of two convex polytopes while their orthogonal projection on the centerline overlap mutually. Afterward it judges the separation of two convex polytopes by confirming non-overlap in orthographic projection on the centerline or by finding out a projection-separation facet from two quasi projection-separation facet sets, otherwise a collision is judged.

该算法通过判断2个凸多面体在中心线上的正投影不相交，或者分别构造它们的准投影分离面集合，并从这2个集合中找到一个投影分离面，来判断2个凸多面体分离；否则，判断为相交。
