    摘要： The corrosion rate of a metal immersed in a fluid medium is measured by transmission of a beam of radiation normally in the visible or near infra-red portion of the spectrum, through a thin film of the metal immersed in the medium. The film of the metal is suitably supported on a radiation-transmitting substrate such as a glass plate or slide. The corrosion rate can be determined by passing a radiation beam through the metal film sample using a twin beam system to compensate for instrument factors such as the absorbance by the fluid medium, the cell windows and the film-supporting substrate. As the thickness of the film decreases, the reduction in film thickness is determined by the increase in beam intensity, using a reference beam to compensate for the instrument factors.

    摘要： Apparatus for transversely irradiating a region equally from two directions using a single incident beam of substantially collimated radiation. The apparatus includes perpendicular reflective planes having a common edge and defining a corner region in which an irradiated region entirely within said corner region, said irradiated region being suitably positioned within said corner region such that said irradiated region does not intercept any ray of incident radiation from striking said common edge, said irradiated region receiving only radiation from two directions. Said irradiated region being directly irradiated from a first direction by incident radiation, and said irradiated region being also indirectly irradiated from a second direction opposite said first direction by incident radiation reflected from both of said planes.
