前置有更多的轨道去头（右侧），而不是在HDA（左侧），这是因为硬盘只能有一个工作的“头”（读一写的一次元素）对。

The preamp has much more tracks going to the heads (right side) than to the HDA (left side), it's because HDD can work only with one "head" (pair of read an write elements) at a time.

计算结果表明，在铺层分界面上有十分明显的应力峰，并发现，即使沿铺层厚度使用16个二次元素，这些值仍没有达到令人满意的精度。

The results show quite distinct stress peaks at layer interfaces, and it was found that even with 16 quadratic elements over the layer thickness these values have not reached an acceptable accuracy.

这与选择排序形成了对比，在选择排序中，你一次又一次地完成寻找最小的元素。

This is in contrast to selection sort where you're fishing looking again and again for the smallest element.

So in this case, it just keeps chopping down from the back end, which kind of makes sense, all right? But in a fixed number, in fact, twenty-three calls, it gets down to the point of being able to say whether it's there.

所以在这个例子中,我们能理解他从后端开始排除元素，这，里事实上每次会确定的运行23次，找到最终的元素,我们来换个方向，对。
