Dme/dme rnp-0.3 na

I'm guessing you see it on an approach plate. It means that if your aircraft uses DME/DME to as the sole means to establish location you can't use that particular procedure. Not a big issue for most light GA aircraft.
Larger aircraft generally use a combination of ways to determine location. For example, my aircraft uses (in this order):
GPS/GPS
GPS
DME/DME
VOR/DME
VOR/VOR
IRS
Dead Reckoning using last know position, heading and speed.

RNP means Required Navigation Performance. So the 0.3 means the equipment must be accurate to a circle of 3/10 of a NM or your position.

As the others have said. You probably have seen this on an approach plate where there is mountainous terrain or lack of adequate navaids. In this instance, aircraft which use DME/DME for navigation will be unable to maintain 0.3RNP and as thus, are not allowed to fly the approach.
