The lossless part can be described in three ways" Y" t- ?/ J. A2 {# S2 n
0. Inductance L' in [mH/m] if Xopt=0 or in [ohm/m] if Xopt=power frequency- M3 n C$ p- Q7 Y1 B
Capacitance C' in [uF/m] if Copt=0 or in [uMho/m] if Copt=power frequency

Xopt. and Copt. are set in menu: ATP|Settings/Simulation./ Y4 \0 v" B8 b0 w+ N
The user can choose conductance modeling G=0 (the usual case) and G=R*C/L (distortionless)

帮助里面的，说的够清楚了吧
8 {2 @' ^- ?; p5 R# ?Xopt在setting里面设置，如果用的是atpdraw的话 |
