请教NCL位势高度场在垂直方向上插值问题

请问大家，int2p_n_Wrap函数在插值位势高度场的时候，linlog应该设置为多少比较准确呀？
linlog
A scalar integer indicating the type of interpolation:
abs(linlog) == 1 --> linear interpolation
abs(linlog) != 1 --> log interpolation
If linlog is negative, then extrapolation to levels outside the range of pin will occur. Use extrapolation with caution.

!=是啥意思？

请问你是怎样将等压面资料插值到等高面上的？
