2. Presentation timestamp - Wikipedia

   en.wikipedia.org/wiki/Presentation_timestamp

   The SCR and PCR are time stamps encoding the timing of the bit stream itself, and are derived from the same time base used for the audio and video PTS values from the same program. Since each program may have its own time base, there are separate PCR fields for each program in a transport stream containing multiple programs.

3. Selective catalytic reduction - Wikipedia

   en.wikipedia.org/wiki/Selective_catalytic_reduction

   In general, the SCR unit is located between the furnace economizer and the air heater, and the ammonia is injected into the catalyst chamber through an ammonia injection grid. As in other SCR applications, the temperature of operation is critical. Ammonia slip (unreacted ammonia) is also an issue with SCR technology used in power plants.

6. Short circuit ratio (synchronous generator) - Wikipedia

   en.wikipedia.org/wiki/Short_circuit_ratio...

   low SCR: in case of a short circuit, the current is proportional to SCR, therefore generators with low SCR require less protection and thus are cheaper; low SCR allows shorter air gap and lower excitation field, both decreasing the size (an cost) of the generator; with low SCR the amounts of iron and copper are reduced, lowering the cost; high SCR:
