The problem with the translation of documentation doesn't allow me to define:
with what parameters it is expedient to use conserve_energy?

finish{... conserve_energy}
finish{ diffuse 1 conserve_energy}  it makes sense?
or
finish { reflection { 0.03, 1 } conserve_energy}

I create nodes, and, it is important to me to define, in what node to place
checkbox conserve_energy?
:)
Help me, please!

I haven't followed your work closely enough to know whether you have a 
node for refraction/transparency, but that's where it should go, as it 
modifies the math used for it.

If I correctly understood, conserve_energy is used, if ior more than 1?

conserve_energy is to be used whenever you have variable reflection and 
any transparency. It can also make things simpler even with constant 
reflection and transparency.

Having an ior or not don't mather.

I tend to use it with layered textures when the upper layer(s) have any 
reflectivity.

It has an effect whenever ior /differs/ from 1 /and/ variable reflection 
is enabled (either via two parameters for reflection, or via the 
"fresnel" keyword).
