Thermodynamic process in which the temperature T({\bf r}) is varying in space but its variation in time is much slower than other dynamic processes so that temperature can be considered as constant at any spatial location {\bf r}:
| (1) | T({\bf r}, t) = T({\bf r}) \Leftrightarrow \frac{\partial T}{\partial t} = 0 |
In specific case when the temperature
T({\bf r}) is not varying in space:
T({\bf r}) = T = \rm const the Quasi-isothermal process is called Isothermal.
