Abstract: An isotope nuclear magnetic method for analyzing ineffective water absorption of rock pores includes steps of: saturating core pores of a core sample with a wetting phase fluid of water H2O, and obtaining a core T2 spectrum after being saturated with the water; re-saturating the core pores with a wetting phase fluid of heavy water D2O, and obtaining a rock baseline T2 spectrum; injecting fluorinated oil into the core sample saturated with the heavy water; injecting the water H2O, simulating a water injection process, and injecting the fluorinated oil, so as to analyze a content of immobile water and obtain a residual T2 spectrum, wherein a range formed by a difference between the residual T2 spectrum and the rock baseline T2 spectrum is an ineffective water absorption portion of the rock pores, and an ineffective water absorption amount is obtained.

Abstract: A pedestal and a method for controlling the same, a tray, and a process chamber are provided. The pedestal comprises: a barrier (12), defining a plurality of areas, in which the plurality of areas are electrically insulated and thermally insulated from each other; a plurality of subbases (11), disposed in the plurality of areas respectively; and a control device, configured for controlling a temperature and/or a power of each subbase (11).
