Increased vertical oxygen gradients after ~15.6Ma and after 13.8Ma indicate increased production of Southern Component Water in association with East Antarctic Ice Sheet growth.
这句话是说 1.垂向梯度的增加表示的是 和E人工智能S增加有关的increased production of Southern Component Water,还是说 2.垂向梯度的增加表示的是 increased production of Southern Component Water 是E人工智能S的增加所致使的?
也就是说 Increased vertical oxygen gradients表明的是 A致使B这个结果 还是表明(因为B所致使的)A这个物体
in association with是做后置定语 还是做 increased production的宾补
谢谢回答
