例如，假如您想要储存在度假时拍摄的某些短片，又或者是mp3文件，那么在储存时所需空间至少要翻一番(一半空间用于实际储存的文件，另一半用于。git目录。)

So if for example you want to store some movies from your holiday or mp3 files, it will at least double the space required for the files (one for the actual file and one copy in the.git directory).

实际摄影测量过程中，普通数字摄像机在拍摄与镜头距离不同的多个目标时，无法同时聚焦到所有目标而使近景影像各处都清晰。

In the actual photogrammetry process, the ordinary digital cameras can not focus all the targets then can not make sure that all close-range images are clear at the same time.
