Field strength increase and

The threshold for reactive scattering is lowered. This effect increases as the field strength increases and also is largest when the laser frequency is equal to the asymptotic splitting between the two potential energy surfaces. This is caused by transitions to the excited state surface where the reaction probability is much higher. 

When corona occurs, current starts to flow in the secondary circuit and some dust particles are precipitated. As potential is increased, current flow and electric field strength increase until, with increasing potential, a spark jumps the gap between the discharge wire and the collecting surface. If this "sparkover" is permitted to occur excessively, destmction of the precipitator s internal parts can result. Precipitator efficiency increases with increase in potential and current flow the maximum efficiency is achieved at a potential just short of heavy sparking. 

For weak electric fields the magnitude of the induced polarization is linearly proportional with the amplitude of the electric field. Yet, when the field strength increases, the linear relationship no longer holds, and nonlinear terms have to be taken into account. In this case, the induced dipole moment and polarization can be expressed up to second order in the electric field as11... 

Plots of the LDOS at the surface (n = 1) site of a 100-atom chain are presented in Fig. 7.3 for various field strengths. For no field, F = 0 (Fig. 7.3(a)), the LDOS exhibits a discretized version of the semi-elliptical shape, familiar for a surface DOS. For small field strength (Fig. 7.3(b)), an almost-linear region appears in the lower end of the quasi-band. As the field strength increases (Fig. 7.3(c) and (d)), the region spreads across the band, with increasing intensities. In addition, there is a rigid shift in the structure to... 

Thus, the precession frequency is proportional to the magnetic strength of the nuclear magnetic moment as well as applied magnetic field. As magnetic field strength increases the precession frequency increases. Table 10.1 shows the relationship between applied field Bo and the precession frequency of a...
