I develop with EMA C++;
I get the INST_PHASE field with FieldId 8927, but I can not understand most of them.
I want to know the meaning of the value.

Hi @luxiangyuan
This fields indicates the current phase of the instrument as listed in the enumerated values table in your question.
If you need more detailed information on what each of those phases represents, I recommend you either contact the specific exchange whose data you are consuming OR create a Content query with our Content helpdesk - as I described in my recent replies to your previous content type questions.
EMA is a data-neutral API and this forum is best suited technical matter on how to use API - content type queries are best handled by subject matter specialist on the Content helpdesk.
