Zhangkun,

your question is not quite clear to me. As I remember the inductances L1 and
L2, mutual inductance M and coupling konstant k fit into the equation

M = k * SqareRoot( L1 * L2)

read as "M equals k multiplied with square root of L1 multiplied with L2" if
text is garbled.

May be you are defining L, M and k in a different way? What is the
background of your problem?

Regards
Thomas

Subject: SPICE Question about mutuel inductance

Dear All
I need to express the following circuit in SPICE. I do not know how to do.
Please give me some advice.

L1=0nH    L2=0nH    M12=M21=-1nH

Best Regards
