我觉得你这句话应该是要用在论文里或者说明书里的吧~
按照工业上或学术上的标准是用一般现在时:
各种对应的论文中的句子有很多,举几个例子给你:
Mineralized matrix deposition by marrow stromal osteoblasts in 3D perfusion culture 【increases with increasing fluid】 shear forces
The in vitro motility of human gliomas 【increases with increasing】grade of malignancy
所以你的句子应该写成
the corrosion rates increase with increasing extrusion ratio
如果需要完成时,那么你要改种说法:
the corrosion rates have increased as the extrusion ratio increased
因为前面是corrosion rates是随着后面extrusion ratio变的,前者完成态,后者也应该是完成态
被动语态一般没有用了,只会使句子更难理解~
