| 1. | Quadrupole absorption line 四极吸管收谱线 |
| 2. | Nmr absorption line 核磁共振吸收线 |
| 3. | At present , even the actual line parameters of the individual absorption line can only be determined to within 10 % . hence , the values are not expected to be more accurate than 10 % 目前甚至个别吸收线的实际线参数精度也只能确定到10 %以内,因此不要期望这些值的精度优于10 % 。 |
| 4. | 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。 |
| 5. | In the paper , the center absorption wave , the absorption shape , the gap between the adjacent lines and the intensity of absorption line are analyzed using quantum mechanics knowledge and molecular spectrum theory . it gives the theoretic description of the beer - lambert law 本文应用量子力学和分子光谱理论分析了气体分子的吸收中心波长、吸收线型、吸收线宽和吸收谱线的强度分布等特性,给出了beer - lambert定律的理论解释。 |
| 6. | It is because when atoms are in low pressure , they can only emit or absorb light of certain wavelengths . if some em wave with continuum spectrum passes through some low pressure atoms e . g . the outer atmosphere of a star , those atoms will absorb the light it likes and creates an absorption line 这是由于低压原子会吸收或发射特定频率的光线,假若有谱线为连续的光通过这些原子例如恒星的表面大气,这些原子便会吸收了特定频率的光线,形成在光谱中有吸收线的现象。 |
| 7. | A comprehensive theory is presented for fm spectroscopy of doppler - broadened molecular iodine absorption lines . the relationship betwcen fm spectroscopy and modulation frequency and modulation index has been studied . the whole circuit for thc frcquency stabilized laser system has been developed 建立了多普勒加宽碘分子线性吸收fm光谱的一般理论,对fm光谱与调制频率和调制度的关系进行了研究;并研制了532nmnd : yvo _ 4 / ktp碘吸收稳频激光器的电路系统;提出了虚拟激光稳频技术的概念。 |
