- It is found that mld based on a temperature change from the ocean surface of 0 . 5 degree celsius is deeper , especially from jan . to apr . , while mld based on a variable density change from the ocean surface with a temperature change of 0 . 5 degree celsius is shallower
分析表明，基于温度阶跃0 . 5得到的mld较深，尤其在1 4月，这可能主要是因为没考虑mld此时受到的盐度变化的影响；基于温差为0 . 5对应的密度定义的mld最浅。 - Based on the theoretical numerical simulation , experimental data of calibration pits , and time - elapsing logging data in cased production pits , a study is made for searching an evaluation method for cementing quality of the secondary interface by variable density logging ( vdl ) , and the eigenvalue about the cementing quality of the secondary interface is obtained
