这是关于薄层色谱(TLC)中的一句话: Any secondary spot in the chromatogram obtained with solution (1) is not more intense than the spot in the chromatogram obtained with solution (2) (0.5%) and not more than one such spot is more intense than the spot in the chromatogram obtained with solution (3) (0.1%). 溶液(1)色谱图中除主斑点外的任何斑点不深于溶液(2)色谱图中相应的斑点(0.5%),and 后面的就不知道怎么翻译了
