The anisotropic distribution of the spherical minor phase gives a component of
interparticle distance ( on the average ) greater in the direction parallel to the
tensile axis than in directions perpendicular to the axis . This sequence of events
is ...

A similar analysis of the experimental results for soda - lime glass gives a 1 / K , ~
250 Å at 247°C . Use of Eq . ( 62 ) , on the other hand , gives 1 / K , smaller than 1
Å . This discrepancy may suggest that the number of charge carriers in glass is ...
