According to Wind observations between 2004 June and 2019 May, this Letter investigates
the proton and alpha particle temperatures in the space of (θ d, V d/VA) for the first time,
where θ d and V d are the radial angle and magnitude of alpha− proton differential flow
vector ${{\boldsymbol {V}}} _ {d} $
