1. The resonance frequency is given by the reciprocal of the characteristic time . 2. The characteristic time -scales are in the range of hundreds of picoseconds in GaAs; 3. Test measures " characteristic time , " which translates to COR. 4. This characteristic time function for temperature-difference behavior, is also associated with Newton's law of cooling. 5. When the illuminating source ceases, the luminescence will persist for a characteristic time , steadily decreasing. 6. Different types of food have different characteristic time -scales. 7. The exact criterion of Frenkel line is the one based on comparison of characteristic times in fluids. 8. Fluids that are described as recoiling generally have characteristic times on the order of a few seconds. 9. All sensors have a characteristic time response. 10. Recoil is related to characteristic time , an estimate of the order of magnitude of reaction for the system.
