Photosynthesizing cells could mostly harness energy at their surfaces, which limited their maximum energy production, which limited their evolutionary avenues somewhat.

光合作用的细胞主要在其细胞表面上利用太阳能，这限制了它们能源产量上限，也在某种程度上限制了它们的进化途径。

These folds are jam-packed with mucus-producing cells, and increase the lip surface area for maximum slime production.

这些褶皱挤满了产生粘液的细胞，并增加了唇部表面积以最大程度地产生粘液。

So, pure C8 - caprylic acid, is your best bet for maximum ketone production, but a mix of C8 and C10 is usually more available and more cost-effective.

因此，纯 C8-辛酸是最大限度生产酮的最佳选择，但 C8 和 C10 混合使用通常更常见，也更划算。

Modern industry is based on the conception of the maximum production at lowest cost, in order that an individual or a group of individuals may earn as much money as possible.

以最低成本获取最多产品，为的是让某个个人或某一部分人尽可能多地赚钱。
