A theory analysis is made for a phenomenon of "linegroup" which is bell shaped, and the spectrum interference between direct path sound and reflected sound is revealed.
从理论上分析了钟型的“线谱群”的产生原因，证明了此现象是反射声和直达声之间的谱干涉引起的。

The three-dimensional symmetry of a macromolecular chain was characterized by the linegroup. Regularities of packing of macromolecular chains in a space group were shown.
