41. The constant T is called the relaxation time of the system and the constant ? is the quasi-frequency. 42. Gadolinium injection causes the relaxation time to decrease, and therefore images done after gadolinium injection have higher signal. 43. This involves using a sharp rise in temperature and observing the relaxation time of the return to equilibrium. 44. In the large majority of crystal systems, electronic relaxation times are orders of magnitude shorter than ionic relaxation times. 45. There were lots of proper suits for the up-and-coming professional, as well as super cashmere sweaters for relaxation time . 46. Where C is the heat capacity, v g is the group velocity and \ tau is the relaxation time . 47. These fluctuations happen on time scales which are much larger than the microscopic relaxation times to the Boltzmann distribution. 48. In the large majority of crystal systems, electronic relaxation times are orders of magnitude shorter than ionic relaxation times . 49. An inversion recovery experiment can be done to determine the relaxation time and thus the required delay between pulses. 50. The water close to the pore wall surface exhibits faster T _ 2 relaxation time for this characteristic pore size.
