A double-subscript scheme will be used to identify the stresses.
For the first two lines, assignment and subscript, it should be fairly unsurprising that the resulting expression node should be binary.
But at the same time, you can refer to an "only child" node without having to subscript. For example.
As an attempt, we inverse the assumingly active faults' slips triggered by the m (subscript s) 8.1 Kunlun Mountain earthquake over Beijing area.
Each subscript refers to a coordinate which represents the location and direction of a force or of a displacement.
Subscript before please read on and I subscript before and after the note and agreed to under the 100 percent standard, so as to avoid loss of interest or misunderstanding.
