    摘要： A method for non-invasive mapping (imaging) of the electrical impedance of an object. The present invention provides a method, current density impedance imaging (CDII) which produces an impedance image of object by measuring current density distributions and directly calculating the local impedance values. The method includes making measurements of at least two current density vector fields, J1 and J2, within a region of interest in an object and then calculating the logarithmic gradient of local conductivity, ∇ In σ(x, y, z), using a formula ∇ ln ⁢   ⁢ σ = ⁢ ( ∇ × J 2 ) · ( J 1 × J 2 )  J 1 × J 2  2 ⁢ J 1 + ⁢ ( ∇ × J 1 ) · ( J 2 × J 1 )  J 1 × J 2  2 ⁢ J 2 + ⁢ ( ∇ × J 1 ) · J 2  J 1 × J 2  2 ⁢ J 1 × J 2 ( 1 ) where {right arrow over (J)}1(x,y,z) and {right arrow over (J)}2(x,y,z), are the pair of measured nonparallel current densities at point (x,y,z) and ∇ denotes the gradient operator.

    摘要： A method of removing volatile and semi-volatile compounds from an aqueous stream is provided which may include injecting a scale reducing gas having a primarily inert gas containing carbon dioxide into the aqueous stream; flowing the stream past a first surface of a wall of a microporous, hydrophobic gas separation membrane that is substantially impermeable to water but is permeable to vapors from the volatile and semi-volatile compounds; applying a vacuum to a second surface of the wall of the membrane to draw the vapors of the compounds through the wall of the membrane; flowing a sweep gas from the first surface of the wall to the second surface of the wall to facilitate movement of the vapors through the wall of the membrane, wherein the sweep gas is a primarily inert gas containing carbon dioxide; and flowing the drawn vapors through an oxidation device to oxidize the drawn vapors.
