Description
ность изменени плазменной термоэ.д.с в процессе нагрева электродов, гарантиру замыкание электродов жидким или твердым плазмообразующим веществом, а второе - чистоту исследуемой среды. Как показали расчеты и опыты, дл цези , например, при Я 130агж этим услови м отвечает скорость нагрева электрода с большей температурой 3000 град/сек. Наконец, скорость нагрева электродов не должна быть слишком большой, чтобы давление илазмы не превышало заметпо давление окружающей среды. Дл указанного давлени цези при скорости нагрева 3000 град/сек давление плазмы превышает окружающее па величину не более дес тых долей атмосферы вполне допустимо. Предложенный способ не имеет ограничений сверху по давлению. Точность регистрации плазменной э.д.с. характеризуетс электрическим сопротивлением межэлектродпой изол ции, которое при реализации предложенного способа может превысить сопротивление изол ции по известному способу на несколько пор дков (папример ом вместо ом), что и обеспечивает повышение точности измерений.the change in plasma thermoelectric power in the process of heating the electrodes, ensuring the closure of the electrodes with a liquid or solid plasma-forming substance, and the second - the purity of the medium under study. As calculations and experiments have shown, for cesium, for example, when I am 130, these conditions correspond to the heating rate of the electrode with a higher temperature of 3000 degrees / second. Finally, the heating rate of the electrodes should not be too high so that the pressure of the plasma does not exceed the ambient pressure. For a given cesium pressure at a heating rate of 3000 degrees / sec, the plasma pressure exceeds the ambient value of no more than tenths of the atmosphere is quite acceptable. The proposed method has no restrictions on the top pressure. Accuracy of registration of plasma emf characterized by the electrical resistance of the interelectrode insulation, which, when implementing the proposed method, may exceed the insulation resistance by a known method by several orders of magnitude (for example, instead of ohm), which provides an increase in the measurement accuracy.
