| 1. | In practice the identification of lines in a star's spectrum is not so easy .
实际上，要辨认恒星光谱中的谱线并不那么容易。 |
| 2. | In chap. 19 we saw that red shifts in stellar spectra result from motions away from the earth .
在第十九章我们已了解到，恒星光谱中的红移是恒星背离地球的运动造成的。 |
| 3. | If you spread the light of a star out into a rainbow and photograph it, you have a spectrum of the star .
如果你把恒星的光分解为彩虹的颜色并且对它拍照，你就得到了恒星光谱。 |
| 4. | The corona activity of late - type main sequence stars also depend on the stellar spectral type
晚型主序星的冕球活动也表现出对恒星光谱型的依赖性。 |
| 5. | By carefully analyzing the spectrum of a star , we can tell which elements the star s surface may contain
只要小心分析恒星光谱中的吸收线，便可以找出恒星表面的物质成分。 |
| 6. | By comparing the absorption lines from a star to those obtained in a laboratory , we can tell whether the star is moving away or towards us and how fast the star is moving
只要比对恒星光谱中吸收线的波长和实验室中同一物质的吸收线波长，我们便可以计算出天体究竟以甚么速度远离或接近我们。 |
| 7. | Furthermore , we also reserch the influence of setllar age to stellar activity of late - type stars . the relation of stellar chromospheric activity and rotation of late - type main sequence stars depend on stellar spectral type
大样本分析显示晚型主序恒星的色球活动与恒星自转参量的研究晚型主序恒星的色球活动与恒星自转参量间的关系表现出对恒星光谱型的依赖。 |
| 8. | 3 . according to the algorithm of attribute reduction , auto - classification system about stellar spectrum data is designed and implemented through using visual foxpro 6 . 0 , which automatically extract rules from stellar spectrum
3 .依据上述属性约简算法，采用visualfoxpro6 . 0数据库管理系统，设计与实现了恒星光谱数据自动分类系统，实现了恒星光谱分类规则的自动提取。 |
| 9. | Finally , as laurence a . marschall reports in planetary prospecting , a clever program to hunt for periodic changes in the spectra of stars has confirmed the existence of numerous giant planets orbiting stars beyond our solar system
最后，正如劳伦斯?玛舍尔在《行星勘探卜书中所说，一个搜寻恒星光谱周期变化的聪明计划证实在太阳系之外有无数个大行星围绕着恒星在做轨道运行。 |
| 10. | The relation between stellar chromospheric activity and rotation of evolution stars have a good relativity . but meticulous analysis show chromospheric activity of evolution stars depend on stellar spectral type and effective temperature strongly . we provide several possible explain for those phenomena
但是细致分析显示演化恒星色球活动水平随恒星自转周期间的分布对恒星光谱型和恒星表面有效温度有很强的依赖，并对这些现象提出了几种可能的解释。 |
