接近效应 meaning in English
closing effect
Examples
- We form a ly a line sample from spectra of 19 qsos in the literature . in this analysis , we demonstrate that a proximity effect is present in the data ; i . e . , there exists a significant deficit of lines at zabs = zem , within 4h - 1 mpc of the qso emission redshift . and the deficit depends on the rest equivalent width of the lines , with weak lines showing a relatively weaker effect
我们发现所选样本中确实存在接近效应，特别在z _ ( abs ) z _ ( em )附近距类星体4h ~ ( - 1 ) mpc范围内， ly森林的线数相对演化规律估计得到的线数缺少很显著，并且与谱线的静止等值宽度有关，弱线的接近效应较弱。
