Description

Примечание. Режим электролиза, например 400io200ioIOOio50io, означает , что в течение 10 мин от начала электролиза плотность тока была посто нна и равна 400 А/мг, в течение следующих 10 мин плотность тока поддерживали равной 200 А/м и т. д.Note. The electrolysis mode, for example 400io200ioIOOio50io, means that within 10 minutes from the start of electrolysis the current density was constant and equal to 400 A / mg, for the next 10 minutes the current density was maintained at 200 A / m, etc.
