Digital Rock Images are three-dimensional datasets of rocks and other porous media.
数字岩石图像是岩石和其他多孔介质的三维数据集。

These are typically acquired using three-dimensional imaging techniques such as Micro-Computer Tomography (MicroCT).
这些图像通常使用三维成像技术（例如微型计算机断层扫描 (MicroCT)）获取。

They represent a rich dataset that form a basis for characterization of physical processes involving porous media.
它们代表了丰富的数据集，为表征涉及多孔介质的物理过程奠定了基础。

Digital Rock Images are scattered throughout the web on various hosting sites such as the Digital Rocks Portal, Zenodo, or university specific sites. This library aims to make downloading these datasets easy through a python interface so they can be used in automated image processing workflows, reproducible research, or data science and machine learning worfklows.
数字岩石图像分散在网络上的各种托管网站上，例如 Digital Rocks Portal、Zenodo 或大学专用网站。该库旨在通过 Python 界面轻松下载这些数据集，以便它们可用于自动图像处理工作流程、可重复研究或数据科学和机器学习工作流程。

Furthermore, these images are associated with metadata about their spatial dimensions which should be considered when loading these image datasets.
The library therefore requires these metadata to be available and creates an xarray DataArray which can keep spatial scale information when loading an image dataset.
此外，这些图像与有关其空间维度的元数据相关联，在加载这些图像数据集时应考虑这些元数据。
因此，该库要求这些元数据可用，并创建一个 xarray DataArray，它可以在加载图像数据集时保留空间尺度信息。

Each dataset is linked in this library i.e. no hosting is done by the library itself.
每个数据集都链接到此库中，即库本身不进行任何托管。
