Constant does not change with coordinate x.It is multiplied by equation (1) with dx, and x is integrated, to obtain following formula.
j·(x-x0)=I (T (x0))-I(T(x)) (2)
Wherein, I (T) is the integral function of K (T).

As electrode length LEWhen reaching one or more predetermined minimum electrode length, measurement module 222 can send out alarm, provide visually
Change instruction and/or even stops operation.In some embodiments, when detecting predetermined minimum electrode length, audio, video
And/or the state of operation alarm can be different or occurs in the different stages.Illustrative minimum electrode length is about 100mm
Or smaller, for example, about 75mm or smaller, for example, about 60mm or smaller, for example, about 50mm or smaller, for example, about 50mm or smaller, packet
Include all ranges and subrange between them.
