Equation [18], with suitable boundary and initial conditions, represents the 3D temperature distribution at any time and at any point in the workpiece. The initial temperature condition refers to the temperature profile within the workpiece at time t = 0. The initial temperature distribution is usu...
The coordinate distribution function has already been obtained (Section 3.2.1). Therefore, this part of the equation can now be withdrawn from consideration, leaving only those terms that depend on the components of the molecules' speed (3.3.4)dw(υx,υy,υz)=dN(υx,υy,υz)N=Cexp[-...

Finally, the Maxwell equations reduce to a second order equation for the electrostatic potential $$\begin{aligned} \bigg (\frac{F_2^2 V'}{F_0 F_1}\bigg )'=4 \epsilon _t q F_1 F_2^2 (P^2+Q^2) . \end{aligned}$$ (3.12) Note that above equations are left invariant by ...
