在电子回旋脉塞动力学理论中，以电子回旋中心坐标系中场的局部展开为基础的方法有很大的优点。

In the kinetics of electron cyclotron masers, the method based on the local field expansion in the guiding center frame has many advantages.

您可以展开到每个局部流程，并将其也打印出来，但是这样将会失去高级视图。

You could drill down into each local process and print it out as well, but then you lose the high-level view.

关于这个问题的辩论在局部和全球范围两个层面上同时展开：生态系统的一小部分可以小到何种程度仍能维持其完整、丰富的功能，从而可以认为是受到了保护呢？

The discussion is taking place at both the local and global levels How small can a fragment of an ecosystem be and still function in all its richness and thus be considered preserved?
