Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

An experimental study of the diusion-gravitational convection transition boundary in an ArN2 binarysystem at dierent pressures and a constant temperature gradient is performed.It is shown that the diusion is replaced by the gravitational convection at a pressure p ≈ 0.5 MPa.In terms of the stability theory, a perturbation boundary line is determined, dividing the Rayleigh numbers plane into the regions of the diusion and the convective mass transfer.The experimental data agree well with the theoretical values.
