元数据缓存器将目录和文件的路径名称保存为键，将元数据保存为值（如文件长度、最后修改时间、标记该条目是文件还是目录等）。
The metadata cache contains the full path names of directories and files as keys and metadata (e.g. file length, last modification date, and whether the key is a file or a directory) as values.

和拖动一样，元键在这里也可以用来约束调整尺寸操作的方向。
As with dragging, a meta - key is often used to constrain the direction of a resize interaction.
先制备具有均一链长的含有酰胺键的硬段单体，然后与二元醇进行缩聚反应生成酯键是制备性能良好的聚酰胺酯的较好途径。
Ester bond can be formed through the polycondensation of hard segment monomer with uniform segment length containing amide bond and dihydric alcohol, which is a better way to prepare polyesteramide.
随着年龄不断增长，有害化学物质会损害我们的神经元和神经键，导致记忆衰退甚至老年痴呆症。
As we get older, toxic chemicals will damage our neurons and synapses, leading to memory loss and even Alzheimer's.

求得可能的四种不同热解反应通道的过渡态、活化能和位能曲线，发现其热解引发步骤为五元环上侧链n—NO2键的均裂。
All transition states, activation energies and potential curves of four possible reaction paths were obtained. It was found that the homolysis of n-no2 bond in five-membered ring is the initial step.
机械地说，我们记忆信息的能力可以归结为大脑中神经元之间连接的强度，神经元通过神经键连接。
Mechanically speaking, our ability to recall information comes down to the strength between neurons in our mind, which are connected by synapses.
苹果公司在使用元键上很长时间以来就具有清晰的标准规范，而且在用法上也越来越一致统一。
Apple has had a history of well-articulated standards for use of meta-keys in combination with a mouse, and there tends to be a fair amount of consistency in their usage.
