Frequency of fluctuation

As grade and frequency of fluctuation are also dependent on this distance, the effect of odour concentration fluctuation must be quantified in this range by reliable measurements... 

Another purpose of a mixing tank is to dampen out fluctuations. A mixing tank cannot change the frequency of fluctuations but can dampen the amplitude. As a general principle, a residence time equal to the cycle time of the fluctuations will cause the amplitude to be dampened by about a factor of six. 

In a polar medium, three types of polarization are observed. The first type results from the deformation of the electron coulds in solvent molecules. The frequency of fluctuation of this polarization, v, is given by... 

Equation (VI. 3) differs from eq. (VI. 1) only by the numerical coefficient. The estimates for CTcr based on eq. (VI. 3) yield, however, the values lower than expected, because this equation does not account for a number of other factors, such as the frequency of fluctuations of a given size and, consequently, the number of particles of this size.
