A strain may be defined as an organic compound containing a benzene ring plus a chromophore and auxochrome group.

染料定义为含有与呈色官能与辅助成色官能的化合物。

The benzene ring and alkene structural group are much more stable than structural group of sulfoacid for the carbonifying process of polystyrene.

在碳化过程中，聚乙烯阳离子换树脂的结构和烯烃团比磺酸团稳定。

The enantioselectivity of N-dodecanoyl-L-proline-3,5-dimethyl-anilide is also good, but the basic line fluctuates strongly due to containing benzene ring in its molecular structure.

虽然用N-十二酰-L-脯氨酸-3,5-二胺作添加剂，手性选择性也较好，但由于含有，紫外吸收增强，线波动严重。
