| 1. | The chromosphere is a frothy layer churned up by gases in the photosphere .
色球层在光球层气体的搅拌下是个多泡层。 |
| 2. | This firmly establishes the nature of the oscillations as low acoustic eigenmodes of the subphotospheric layers .
这就确凿地证实了振荡的本质是次光球层的低频声波本征模式。 |
| 3. | There is no sharp break between the photosphere and the outer atmosphere of the sun on one side and the solar interior on the other .
无论在光球与它上面的太阳大气之间，或是在光球层与它下面的太阳本体之间，都没有明显的突变。 |
| 4. | Its temperature is higher , with a typical value of 10
它的温度比光球层更高，很多时为10 |
| 5. | Above the photosphere is another layer of gas , about 2 , 000km thick , called the
在光球层之上，是一层约为二千公里厚的 |
| 6. | Thus , the photosphere defines the surface of the sun . its temperature is about 6000k
所以，光球层界定了肉眼可见的太阳表面，它的温度约为绝对温度6000度。 |
| 7. | K . it is much fainter than the photosphere , so we can see it usually only during a total solar eclipse
度。有趣的是，它相对来说比光球层暗，所以通常只能在日全食时才能看见它。 |
| 8. | K . we still cannot completely explain why the temperature of the chromosphere and corona can be higher than the photosphere
度。为甚么日冕和色球层的温度可以比光球层更高，仍是天文学上一个未解之谜。 |
| 9. | It turns out that zinc , gallium , and copper are very difficult to measure precisely in the solar photosphere so our measurements of the sun may not be quite right
其结果是在太阳光球层中的锌、镓、铜恰好是很难测定的，那么我们对太阳的测量方法可能不是很正确。 |
| 10. | Are dark small regions on the sun . their temperature is only 4000k compared to 6000k elsewhere in the photosphere . since they are cooler , less light is produced and they appear as black spots
是太阳的黑暗区域，温度只有约4000度，由于相对来说它们比光球层其他地方冷，产生的光亦较少，所以看来较暗。 |
