词汇 calorimeter
释义

Definition of calorimeter in English:

calorimeter

noun ˌkaləˈrɪmɪtəˌkæləˈrɪmɪdər
  • An apparatus for measuring the amount of heat involved in a chemical reaction or other process.

    热量计,量热器

    Example sentencesExamples
    • It functions as what physicists call a calorimeter, measuring the total energy of the deposited gamma rays.
    • The cells were stabilized for 4 hours at 25 degrees celsius inside the calorimeter before heating up to the final temperature at a heating rate of 0.5 degrees celsius per minute.
    • This calorimeter, which contains 400 kilograms of liquid krypton, detected the photon pairs.
    • The reaction takes place in an apparatus called a calorimeter, which is specially designed to completely insulate the reaction system so no heat is gained from or lost to the surrounding environment.
    • They used the ice calorimeter to measure the heat given off by a guinea pig as it breathed oxygen, relating this heat to that of a chemical reaction occurring inside the animal.

Derivatives

  • calorimetric

  • adjective ˌkalərɪˈmɛtrɪkˌkælərəˈmɛtrɪk
    • The key issue of this paper is to relate thermodynamics data, especially calorimetric data, of peptide-containing membranes to the aggregation of the peptides.
      Example sentencesExamples
      • Scanning calorimetric experiments show that proteins do have a heat capacity.
      • The interaction again resulted in a significant heat release and a calorimetric titration curve could again be constructed.
      • Protein solutions for the calorimetric experiments were prepared by exhaustive dialysis against the buffer.
      • Kinetic and calorimetric criteria are usually applied to determine whether or not a folding reaction follows a two-state model.
  • calorimetry

  • noun ˌkaləˈrɪmɪtri
    • Samples were heated in a home made calorimeter, enabling simultaneous differential scanning calorimetry on the very same sample.
      Example sentencesExamples
      • Estimated energy requirements determined via indirect calorimetry and mean energy received did not differ.
      • The prediction was tested by constructing the corresponding phase diagram using low- and wide-angle x-ray diffraction, differential scanning calorimetry, and polarized light microscopy.
      • Encouraged by the textile industry, a great amount of work using differential scanning calorimetry has been undertaken.
      • For this research, we'll be using scanning electron microscopy, x-ray diffraction, differential scanning calorimetry, and thermomechanical analysis.

Origin

Late 18th century: from Latin calor 'heat' + -meter.
