Russian term or phrase: К33 или Кзз

The same patent specification (on a process for producing a piezoelectric ceramic material) includes a table of test results comparing the proposed process with the prior art.
One of the parameters is К33
or Кзз. The second and third symbols are in subscript and hand-written, so it is impossible to distinguish between numeral 3 and Cyrillic letter з. If the latter, does anyone know what зз stands for?

Коэффициент энергетической эффективности

Explanation:
That's all that I ahve managed to find so far with the help of Internet.

Nothing on КЗЗ - except space technology, which is obviously not the case here.

What stands close here is КЭЭ, which looks very similar to КЗЗ, and means коэффициент энергетической эффективности.

See if it fits.

Godd luck!
