However, as Zhang sected tangentical multiped station distance Zhang of cards and membership cards making-position when compared to paper for a relatively long, Zhang cut registration error to chromatometry methals overprinter error.

但由于弛切工位间隔弛切线的制卡和会员卡制息工位较近，纸弛比辛不幼，所以弛切的套准误不不差给比色间的套印误不不差相不不差不小一些。

Analyses show that the theoretical form of camber curve should be a parabolic curve of 4 degree with horizontal tangents at both beam ends, while the common crane building praxis uses a parabola of 2 degree.

分析结果指出，合理的预拱曲线应当是两端具有水乎切线的四次抛物线，而不是通常采用的二次抛物线。

Firstly, the curvature continuity conditions between two adjacent rational quadratic curve segments are derived. Secondly, an optimal algorithm is presented for solving out the tangent lines at every points of a closed point set in a plane.

If the slope of the secant is greater than the slope of the tangent then the curve is inelastic at the point.

如果某个点的切线的斜率小于该点与原点构成的割线的斜率，那么该函数函数在该点上为非弹性。

The contact angle is the angle between the tangent line at the contact point and the horizontal line of the solid surface.

接触角是角之间的切线的联络点和水平线的固体表面。

You therefore need to break the symmetrical interdependency between the two tangents.

在这个情况下，不管这样，你想使曲率的通路向在相同方向两边的曲线点陡峭。你因此需要隔断两切线的对称性。
