翻译一下：上述结果表明虽然NdIII在模拟NdFeB进料溶液中的比例远大于DyIII但P350-PEG 200萃取体系仍能优先地萃取DyIII完成NdIII和DyIII的高效分离。

The above results indicate that although the proportion of Nd(III) in the simulated NdFeB feed solution is much greater than that of Dy(III), the P350-PEG 200 extraction system can still preferentially extract Dy(III), achieving efficient separation of Nd(III) and Dy(III).
