Изобретение относитс к технологии электронных устройств и предназначено дл измерени парциальных давлений смеси газов в процессе изготовлени и эксплуатации газовых чеек дл квантовых стандартов частоты с оптической накачкой , газовых лазеров if других приборов , наполн екалх смесью газа.The invention relates to the technology of electronic devices and is intended to measure the partial pressures of a mixture of gases in the process of manufacturing and operating gas cells for quantum frequency standards with optical pumping, gas lasers if other devices filled with a mixture of gas.
Известны способы измерени парциальных давлений с помс цью омегатрон либо соединенного с исследуемым , либо путем разрушени колбы с исследуемым газом.Methods are known for measuring partial pressures with a pressure omegatron, either connected to the test or by destroying the flask with the test gas.
Известен также способ определени парциального давлени , основанный на регистрации и исследовании оптических спектров, возбуждаемых подачей достаточно высокого напр жени на электроды, специально дл этого впа нные в исследуемую чейку 11.There is also known a method for determining the partial pressure, based on recording and studying optical spectra excited by applying a sufficiently high voltage to the electrodes, specifically for this purpose driven into the cell 11 under study.
Наиболее близким к изобретению по технической сущности вл етс способ измерени парциальных давленип в смеси газов, заключак цийс в возбуждении электромагнитным поле газовой смеси, помещенной в замкнутую чейку, измерении спектральных характеристик газовой смеси и расчета й6 полученным данным с учетом, эталонных спектральных характеристик парциальных давлений 12.The closest to the invention to the technical essence is a method of measuring partial pressures in a gas mixture, concluding with the excitation of an electromagnetic field of a gas mixture placed in a closed cell, measuring the spectral characteristics of the gas mixture and calculating the received data taking into account the reference spectral characteristics of partial pressures 12 .
Недостатком всех известных способов- вл етс недостаточна точ- ность определени парциальных давлений , особенно при исследовании многокомпонентных смесей.The disadvantage of all known methods is the insufficient accuracy of the determination of partial pressures, especially in the study of multicomponent mixtures.
Цель изобретени - повышение точ0 тности измерений.The purpose of the invention is to improve the measurement accuracy.
Поставленна цель достигаетс за счет того, что в спосЪбе, Заключаиощемс в возбуждении электромагнитньм полем газовой смеси, помещенной в замкнутую чейку, измерении спектральных характеристик парциайьных давлений в чейку ввод т пары изотопов щелочных металлов, число которых равно числу газов в анализируе 4ой смеси, измер ют частоты пере0 ходов каждого изотопа щелочного металла и с учетом частотной разности между измеренными и этгшонными частотагет переходов наход т парциальные .давлени .The goal is achieved due to the fact that in the process of Exciting by the electromagnetic field of a gas mixture placed in a closed cell, measuring the spectral characteristics of partial pressures, alkali metal isotope pairs are introduced into the cell, the number of which is equal to the number of gases in the fourth mixture being analyzed frequencies of transitions of each alkali metal isotope and taking into account the frequency difference between the measured and etched frequency transitions, partial pressures are found.
Способ осуществл етс следующимThe method is as follows.
образом.in a way.
Ввод т в Объем газовой чейки, наполненной смесью п-газов, пары п-изотопов щелочных металлов,помеIntroduced into the volume of a gas cell filled with a mixture of p-gases, a pair of p-isotopes of alkali metals,
