| 释义 | calorimeter noun[ C ] uk /ˌkæl.əˈrɪm.ɪ.tər/ us /ˌkæl.əˈrɪm.ə.t̬ɚ/ a piece of equipment for measuring the amount of heat produced in a chemical reaction热值测量仪 Laboratory equipment aspirator bell jar bubble chamber Buchner funnel Bunsen burner condenser evaporating dish flame test flask litmus microscope particle accelerator photometer pipette retort stand scope siphon synchrotron test tube transducer An apparatus known as the bomb calorimeter has two chambers, the inner, which contains the dry food to be burned, say a definite amount of sugar, and an outer, which is filled with water. At one end, on the ground floor, is the exposing and recording apparatus for flame tests of explosives, also pressure gauges, and a calorimeter, and, at the other end, is a gallery for testing safety lamps. M. Curie has calculated directly, by the aid of the calorimeter, the quantity of energy liberated, measuring it entirely in the form of heat. The data which we have used were obtained by the use of a calorimeter measuring the quantity of heat passing through covering. The respiratory calorimeter is an air-tight compartment in which men are confined for a week or more at a time while studies are being made concerning heat and energy yielded by food products. calorimeter | American Dictionarycalorimeter noun[ C ] us/ˌkæl·əˈrɪm·ɪ·t̬ər/ chemistry a piece of equipment for measuring the amount of heat produced in a chemical reaction Examples of calorimetercalorimeter The calorimeter was placed after the focus mirrors array. The energy in the microwave pulse batches was measured with a calorimeter with an alcohol microwave absorber and a capillary indicator. The laser per formance was characterized with an optical streak camera, equivalent plane monitor, and calorimeter measurements. The same spiral served to calibrate the calorimeter by discharging a capacitor with a known energy. He measured the heat increment in a respiration calorimeter as the difference in heat resulting from ingested feed at two intake levels. The focused beam from the parabola was then sent through pinhole targets and onto a large area calorimeter. Before lowering, ampoules were suspended within the calorimeter unit to allow for temperature equilibration. We have measured the transmitted and backscattered laser light with the fast photodiode and calorimeters, and analyzed the energy balance. Rather, it encouraged the use of instruments yielding quantitative data: balance, thermometer, and calorimeter. The total energy of the six beams was measured by a calorimeter with diameter of f100 mm. The pulse energy was measured with a calorimeter having an alcohol-filled glass tube intended to absorb microwaves. The calorimeter measures the change of temperature in a thin layer of material due to its heating by the passing ion beam. Rapid measurement of binding constants and heats of binding using a new titration calorimeter. The total number of calorimeter channels in this experiment was 18. Both input and output beams being almost fully overlapped in the amplifier were measured by means of calorimeters and vacuum photodiodes. These examples are from corpora and from sources on the web.
