CONCEPT OF BREAK-EVEN POINT IN THE CONDITIONS OF A SMALL REPAIR COMPANY
DescriptionThe article has stated that, subject to the conditions of existence of break-even point, a negative value indicates the manufacturing arm of the loss-making activity of a small repair shop
-
Description
The article found that the distribution of the normal components of the along the length of the samples has no significant features associated with different magnetic characteristics, so the magnetization modes of an additive powder on the details of uncertain chemical composition must be installed on the tangential component of the magnetic field
