This rock suite, with a high abundance of Au-Ag, formed a tight linear fold, in which fractures were well developed.

这套岩系金、银丰度高，形成紧密的线状褶皱，断裂构造极为发育。

In the late 1980s, they discovered that although a linear string of amino acids can fold into its proper three-dimensional shape in a test tube, the protein cannot do this on its own within a cell.

他们在20世纪80年代晚期发现，尽管一串线性氨基酸可以在试管中折叠成特定的三维形状，但蛋白质自身不能在细胞内完成这一过程。

As compared with the corresponding results in the linear bilevel programs, our generalizations are two-fold: the objective function and the condition that should be satisfied.

与线性双层规划的有关结果相比较，该文在目标函数和所要求满足的条件两方面都有推广。
