IN THE dry desert on the west coast of Namibia, where the annual average rainfall is a meagre 40mm, the Namib beetle (Stenocara gracilipes) has evolved a unique mechanism to drink.
在年平均降水量仅有40毫米的纳米比亚西海岸的干燥沙漠里，纳米布甲虫已进化出独特的集水机能。

To study regional average stress field, we need to choose a population of focal mechanism solutions of earthquakes in the massifs where there are significant tectonic structures.
选择具有地震构造意义的地块或地震带内大量地震的震源机制解研究区域平均应力场。

The mechanism minimized the size of CRLs that relying parties had to download, the peak and average loads on CRL repositories, alleviated time granularity and scalability.
