There is much work that remains to be done with the visible emissions.

There are no visible emissions which would indicate that lead is being released into the air.

Concern for air pollution focused exclusively upon visible emissions, especially smoke.

The visible emission was still too faint for eyes to make out, but quite enough for their instruments.

They'd spend good money on a device to suppress the visible emission, then quickly make up the cost in cheap fuel.

To prevent visible emission of steam, two opposite systems were used:

However, the wavelength of the visible emission is much longer than predicted by the Bohr relation and the 19 V interval.

Later that year, Nick Holonyak, Jr. demonstrated the first semiconductor laser with a visible emission.

It's just water vapor; the E.P.A. strictly regulates visible emissions.

All of the installations to date and those in progress have been very effective in the elimination of visible emissions from power station chimneys.
