lead sulphideの例文

• Gilt items showed the presence of mercury, indicating the lead sulphide.
• These also used receivers which employed lead sulphide detector cells and amplifiers, boosting their range to under optimal conditions.
• The missile's uncooled lead sulphide passive infra-red seeker head detects infrared radiation at below 2.8 ?m in wavelength.
• The seeker head is an unusual construction, using uncooled lead sulphide ( PbS ) detector elements, but with an unusual tracking mechanism.
• The lead sulphide mineral galena PbS was mined as an ore of lead, and the sulphides pyrite FeS 2 and sphalerite ZnS were also present.
• Lead sulphide ( PbS ) and indium antimonide ( InSb ) LDRs ( light-dependent resistors ) are used for the mid-infrared spectral region.
• "' Niello "'is a black mixture of copper, silver, and lead sulphides, used as an inlay on engraved or etched metal.
• An early application of isotope dilution in the form of radiotracer method was determination of the solubility of lead sulphide and lead chromate in 1913 by George de Hevesy and Friedrich Adolf Paneth.
