Crepe effect coefficient is defined as the product of the surface geometric structural parameters, i. e, amplitude of weft, density of weft, and number of wefts in unit length.

绉效应系数，被定义为表面几何结构参数，即纬线的波高、纬密和纬线单位长度中的半波数的乘积。

The researchers in this study examined the geometric structure and behaviour of one of the rotavirus's surface proteins, called VP4, which plays a key role in binding on to the surface of a target cell, and breaking through its membrane.

It recommended using geometric lines of latitude and longitude to convey a three-dimensional Earth on a two-dimensional surface, and it included the co-ordinates of over 8, 000 locations in the ancient world.
