A surface that deviates from planarity in a smooth, continuous fashion.

曲面:一个光滑且连续地偏离水平面的面.

Typically, bonds with some degree of double bond character are excluded from minimization so that planarity is preserved.

特别的，有一定程度双键特点在最小化是将被排除从而保留了平面。

图5，锡高转移的效率与孔面积比率及它对回流峰共面度的影响。

The conveyor system made through mylar rolls (from roll to roll and recoverable if necessary), assures maximum planarity and cleaning of panels.

传送系统由聚酯薄膜滚筒构成（如必需可实现卷到卷），确保板料的平整性和清洁性。

Finally, the non-planarity of vertex and the degree of triangle deformation are combined, and the cost function of edge collapse is established to guide the mesh simplification.

最后，综合顶点不平度和三角形的变形误差，建立边折叠代价函数，并以此指导网格的简化。
