The first development is to double membrane permeance
by replacing conventional porous supports used to fabricate composite membranes with novel isoporous supports.
The actual language is "spray foam with a maximum permeance
The results indicated water vapor permeance
declined by 30% to 40%.
Therefore, to reduce the amount of heavy rare earth used, engineers need to reduce the demagnetizing fields acting upon magnets and increase magnet permeance
to allow use of low-[H.
They once again concluded the difference in aging rates was related to the permeance
of the plastic facings and foam temperature.
The determination of the magnetic circuit parameters for the considered machine begins with defining the permeance
of the magnet [P.
These include elongation, water vapor permeance
and absorption, flame retardancy, and fungi resistance, to name a few.
harmonics in electrical machines, with special reference to a synchronous machine.
The air barrier material, which must be structurally supported to withstand the maximum positive and negative air pressures to which it will be exposed, may have only a limited air permeance
Afterwards, the slots are taken into account by introducing a permeance
function of the slots.
measurements on individual paper layers
Calcination and dealumination of kaolinite did not improve coated paper roughness, while air permeance
and optical properties significantly increased in comparison with commercial kaolinite.
