谁能帮我翻译一下这句话？

For papers with more than eight authors, the last name and initials of the first author only should be listed, followed by a comma and "et al." References listed as "et al." are grouped together and last, as if the second author started with "z"; they are not alphabetized by the name of the actual second author.

只有红色一句不知道是什么意思。

如果有两篇参考文献:
1.   Axx, K., Bxx, M., Sxx, P., and Txx, J. 2005 ApJ ....
2.   Axx, K., and Cxx, W. 2005 MNRAS ....

那么它们的正确顺序是:

Axx, K., and Cxx, W. 2005 MNRAS ....
Axx, K., et al. 2005 ApJ ....

那个 Bxx, M. 等人被 et al. 代替了, 而被 et al 的部分就等价于 Z姓开头, 所以要往后挪
