Positive / plus ????

Offset:
Defines the contact offset. Positive values move the contact closer together (increase penetration/reduce gap) and negative values move the contacts further apart. This setting is displayed only if Interface Treatment is set to Add Offset, Ramped Effects or Add Offset, No Ramping.

Add Offset, Ramped Effects:
Models the true contact gap/penetration plus adds in any user defined offset values. This setting is the closest to the default contact setting used in the Mechanical APDL application except that the loading is ramped. Using this setting will not close gaps. Even a slight gap may cause bodies to fly apart. Should this occur, use a small contact offset to bring the bodies into initial contact. Note that this setting is displayed only for nonlinear contact.

这个定义就不一样的，positive和negative是表示数值的正负问题，plus一般是指进行一个加法运算
