I want to let the zone take constant outdoor air fraction in E+. for example, when the zone volume is 100m3, how can i let the outdoor air 30m3 per hour constantly?

I hope I'm understanding this question correctly. This is straightforward in EnergyPlus. In your SpaceType object, you can set a DesignSpecification:OutdoorAir object (documentation) and specify outdoor air flow in Air Changes per Hour (ACH) at 30/100 = 0.3 ACH. You can specify a schedule, though the default is always on, which is what you want.

In addition to @mdahlhausen suggestion above, take a look at ZoneVentilation:DesignFlowRate
