When the three quantities defined above are considered for monochromatic radiation, they are designated by writing the name of the quantity preceded by the adjective I1spectral“, and by writing its symbol followed by A in parentheses (e.g., (A). These quantities are functions
11、 of wavelength A. In this report the angles of irradiation (illumination) and viewing are denoted by two subscripts, separated by a slash (e.c., 45/0). The first subscript indicates the angle between the direction of irradiation. illumination and the noma1 to the surface. The second subscript indica

Properties ref. review A2 Coatings of smoked MgO obtained on polished copper have a higher reflection factor than those obtained on
14、two coats of a hard mat white enamel. Efforts to increase the thickness of the oxide coating by prolonged smoking showed that there is still room for considerable error due to unevenness in the coating. Coatings on silver-plated copper were easily reproducible provided that a thickness of roughly 0.
15、3 mm at least was aimed at. From the measurements it is seen that with a normally incident beam the.smoked MgO layer is equivalent to the perfect reflecting diffuser when the angle of view is 45O. A4 AS A possible hypothesis to account for the alleged yellowness of smoked MgO is the assumption that
16、d. small amount of magnesium nitride might be deposited with the oxide. It is formed when magcesium is burned ln air with insufficient draft to supply an adequate amount of oxygen. The nitride is notably yellow. It is shown by a graph that smoked MgO has a reflectance (P,) greater than 0.95 for the
