invariant

The invariant space has to be as well a deformation of a classical space, a deformation that makes it noncommutative..这些不变的空间同样也是经典空间的变形，它们通过这种变形成为非对易空间。

Crucially, this was true at all frequencies, which means the phenomenon is scale invariant - the other key criterion for self-organised criticality..最重要的是，所有的频率都是这样，意味着这种现象是规模不变的-自我组织临界的另一个重要标准。

For example, in an accounting application, consistency would include the invariant that the sum of all asset accounts equal the sum of all liability accounts..例如，在记账应用程序中，一致性可能包括所有资产账户的总和始终等于所有负债账户的总和这个不变式。

a point in space, rather than its coordinates, is an invariant.
