| 6. | In astronomical situations, the natural line width is seldom directly observed .
在天文学研究中，谱线固有宽度很少能直接观测到。 |
| 7. | The lines of such a pattern may overlap, producing a less easily interpreted pattern .
这种图形的谱线可以重叠，产生较不容易解析的图形。 |
| 8. | For the fundamentals, b'-b"is very small and therefore the lines are almost equidistant.
对于基频振动来说，B-B很小，因此谱线是几乎等距离的。 |
