•The isotopic ratio of the lead is measured with (or by) a photoelectric cell.
•There is no way of gauging the external gravitational field.
* * *Измерять(ся) -- to measure, to take, to take readings; to meter (расход); to gauge (толщину, давление); to read, to sense, to detect (с указанием прибора); to determine (определять по результатам измерений)The cylinder temperature was measured with a calibrated copper-constantan thermocouple in conjunction with a 0.1°F ASTM-certified thermometer.The air was metered by one of two calibrated sharped-edged orifices.The heat transfer data on the prototype was to be taken at mid span.Thermocouple emfs were read with a Hewlett-Packard 3465A digital multimeter with a smallest digit of 1 mV.The pressure signals were sensed by a Baratron solid-stale capacitance-type meter capable of being read to as low as 10-3 torr.The impact-static pressure difference was detected by a Baratron meter capable of discriminating 10-3 mm Hg.The oil flow was determined with a calibrated cylinder and a stopwatch.Измерять по-- It was measured directly from the visualization patterns on the model surface.Русско-английский научно-технический словарь переводчика > измерять
