摘要：
The weak localization effect has been studied in macroscopically inhomogeneous diffusive 2D systems and diffusive constrictions. It is shown that such systems can reveal a saturated behaviour of the low-temperature dependence of that parameter, which is obtained front the standard analysis of the negative magnetoresistance and is usually identified by experimentalists with the phase breaking time.
