如果有的文献没有pages信息,那么应该有文献在对应期数里的编号,到DOI栏中找,ARTN后面的数字就是文章号,如下:

[1] ZHOU N, ZHANG J X, YAN H, et al. Deformation behavior of hard roofs in solid backfill coal mining using physical models [J]. Energies, 2017, 10(4): 557.

[2] Theoretical research on mass ratio in solid backfill coal mining [J]. Environmental Earth Sciences, 2016, 75: 586.

[3] DENG X J, YUAN Z X, LAN L X, et al. Roof movement and failure behavior when mining extra-thick coal seams using upward slicing longwall-roadway cemented backfill technology [J]. Adv Mater Sci Eng, 2020, 5828514.
