Note. In the group of indices first index indicates the minimum value of the index and the third index at the same time characterizes the minimum values of and . If the figures and according to table.3 correspond to different indices, the third index is set at the minimum value of the index and the group indexes introduced in parentheses indicate the fourth additional index characterizing the rate (see example of drawing up the group index for the electrodes UONII 13/45).
