Question

英文改错

This may be attributed to the increase of dislocations density in grains and more severe aberrance of crystal lattice with an increase of extrusion ratios.
这可能是由于挤压比增加使得晶粒位错密度增加，以及更严重的晶格畸变。
英文不对要求重写，谢谢！

Answer 1

从你的分析中，中文句意归结原因在于“挤压比的增加”
而attribute的用法是attribute A to B：把A现象归因于B
那么to后面应该接的是原因，而你接的确是结果。我个人觉得错误在这里。

我想应该写成：
The increase of dislocations density in grains and a more severe aberrance of crystal lattice may attribute to the increase of extrusion ratios.

也可以换用leads results等等动词

希望回答对你有帮助

Answer 2

It's more likely that the compression leads to the increase of dislocation density of crystal grains than the increase,even the severer aberrance of crystal lattice.
变下语序好懂点
It's more likely that the compression leads to the increase of dislocation density of crystal grains even severer aberrance of crystal lattice than the increase.
