There are many helixes ofdihedralAngle, and the whole skeleton forms a large helix in the structure of the rotatory isomer.
其结构中包含许多二面角螺旋，而且具有旋光性的异构体，其结构的整体骨架也构成一个大的螺旋。

This article gives the volume inequality of higher dimension simplex about interface and dihedralAngle, then sets up regular simplex's volume formula which differs from definition.
In terms of FFDP and velocity aberration compensation theory, a new method of using dihedralAngle offset for compensating velocity aberration in large observation range is put forward.
