(Of course, there are other conditions that must be

such as small gyration radius, small Debye length, etc. We do not stress these in

the fluid theory.) Substituting (8') in (5) and (7) and these in (2) we have dW 1.

It is easily shown from (11) that the time derivative of (22) is zero if (23) is

. (This is just (60-16t)+V-J-1 = 0.) Similarly the time derivative of (23) gives Ne? (
