偶偶核 meaning in English
even-even nucleus
Examples
- Lastly , using four - parameter bohr - mottelson formula , we analyzed some ground rotational bands of even - even nuclei . the nuclei included superdeformed ( sd ) nuclei in a - 150 , 190 regions and normal deformed ( nd ) nuclei in actinide and rare - earth
三、利用bohr - mottelson的i ( i + 1 )四参数展开式分析了a 150 ， 190偶偶核超形变带和锕系、稀土区偶偶核正常形变转动带。 - Based on researching the relation of the parameters of bohr - mottelson rotational spectra formula from two - parameter harris formula , in this thesis three - parameter harris formula was used and a new ralation of the parameters of bohr - mottelson rotational spectra formula was brought forward . four - parameter i ( i + 1 ) expansion was used to calculate superdeformed ( sd ) bands of even - even nuclei in a ~ 60 , 80 , 130 , 140 , 150 , 190 regions and normal deformed ( nd ) bands of nuclei in actinide and rare - earth , the relation of the parameters was discussed . comparatively , the new relation is consistent with experiment
利用harris两参数公式研究bohr - mottelson转动谱公式参数之间的关系的墓础上，改用harris三参数公式，并由此提出了bohr - mottelson转动谱公式参数之间的新关系式，进而用i ( i + 1 )四参数展开式计算了a 60 ， 80 ， 130 ， 140 ， 150 ， 190区超形变偶偶核的基带和锕系和稀土区正常形变核基带，讨沦了参数之间的关系，发现新关系式与实验较好地符合。 - Secondly , on the base of pairing correlation , the odd - even differences of nuclear qualities were researched systemically , then we educed the following three mostly research results . first , from the binding energy formula of the nuclear , fitted the nucleus experimental data of the a - 130 , 150 and 190 regions by using the odd - even differences formula of binding energy , the odd - even differences of binding energy were observed , it showed that even - even nucleus were steadier than neighboring odd - even ones and odd - even nucleus were steadier than neighboring odd - odd ones , this conclusion accorded with the experimental results
本文的重点是在对关联的基础上，系统地研究了原子核性质的各种奇偶差，主要研究结果有以下三个方面： ( 1 )从原子核的结合能公式出发，运用结合能奇偶差的公式，拟合a为130 ， 150和190区的原子核的实验数据，可以看出结合能存在的奇偶差，表明偶偶核比相邻的奇偶核稳定，奇偶核比相邻的奇奇核稳定，得到了与实验一致的结果。
