  • Parts per million
rdfs:comment
  • The term parts per million (abbreviated ppm) described a ratio of density used for measuring small concentrations of a substance within a mass/volume of a much larger one. Hadron count, ion trace, and ENC ratio might be measured in PpM (ENT: "Divergence") To revive the crew in 2367, Data used five parts per million of ADTH. (TNG: "Clues" ) Beta Agni II's water supply was contaminated with forty parts per million of tricyanate later that year. (TNG: "The Most Toys" ) To counter a graviton field, Jadzia Dax used one part per million of tridium in 2369. (DS9: "Q-Less")
  • De term parts per million (afgekort tot ppm) wordt gebruikt om in de natuurkunde de verhouding van kleine concentraties van een materiaal in die van een ander materiaal aan te geven. De meest gebruikte toepassing is die in een vloeistof of gas. 1 ppm = 0,0001% = 1:1000000

  • The term parts per million (abbreviated ppm) described a ratio of density used for measuring small concentrations of a substance within a mass/volume of a much larger one. Hadron count, ion trace, and ENC ratio might be measured in PpM (ENT: "Divergence") To revive the crew in 2367, Data used five parts per million of ADTH. (TNG: "Clues" ) Beta Agni II's water supply was contaminated with forty parts per million of tricyanate later that year. (TNG: "The Most Toys" ) To counter a graviton field, Jadzia Dax used one part per million of tridium in 2369. (DS9: "Q-Less") A class 17 nebula in the Delta Quadrant was composed of 7,000 parts per million of sirillium in 2373. (VOY: "Flashback") Seventeen parts per million of argonite was well under safety margins for the air supply on Deep Space 9. (DS9: "Doctor Bashir, I Presume")
  • De term parts per million (afgekort tot ppm) wordt gebruikt om in de natuurkunde de verhouding van kleine concentraties van een materiaal in die van een ander materiaal aan te geven. De meest gebruikte toepassing is die in een vloeistof of gas. 1 ppm = 0,0001% = 1:1000000 * Om de bemanning van de Enterprise-D weer bij kennis te krijgen gebruikte Data vijf parts per million ADTH. (TNG: "Clues") * De watervoorziening van de planeet Beta Agni II was later dat jaar besmet met 40 parts per million tricyanate. (TNG: "The Most Toys") * Om een graviton veld te weerstaan gebruikte Jadzia Dax in 2369 1 parts per million tridium. (DS9: "Q-Less") * 17 parts per million argonite was ruim onder de veiligheidsmarge van de luchtvoorziening van Deep Space 9. (DS9: "Doctor Bashir, I Presume?")
