    摘要： An arc tube of fused silica for a metal halide arc discharge lamp including a fill for the arc tube comprised of a sodium halide, at least one additional metal halide, and an inert starting gas, the arc tube including a tube of fused silica having an inner wall defining an arc chamber, the inner wall of the tube having provided thereon a metal silicate coating which is vitreous and light-transmissive, and which is comprised of a silicate of at least one metal selected from the group consisting essentially of scandium, yttrium, and a rare earth element, and preferably which is the same metal as that of the at least one additional metal halide. Protection of the fused silica arc tube with the metal silicate coating reduces loss of the metallic portion of the fill by diffusion or reaction and corresponding buildup of free halogen in the arc tube.

    摘要： A microwave handheld radiometer for measuring subsurface tissue temperature of a subject includes a microwave antenna disposed relative to a handheld radiometer housing and adapted to electromagnetically couple to a skin surface of a subject, a circulator having a first circulator input and a second circulator input, wherein the first circulator input is electrically coupled to said antenna via a microwave feedline. A switch is electrically disposed between the antenna and an microwave feedline, said switch having a calibrate state and a measure state. A noise source, electrically coupled to the circulator, is being configured to provide a first source of thermal noise at a first temperature and a second source of thermal noise at a second temperature, wherein the noise source is switched between the first source and second source upon external command wherein a detector provides an output wherein surface temperature effects are corrected for the sub-surface measurement.
