Abstract
Способ определения электропроводности массового потока в трехмерном целевом объеме (2), включающий этапы размещения электродов (3) в измерительной связи с целевым объемом; приложения переменного напряжения или переменного тока к целевому объему между двумя электродами (3) и измерения тока или напряжения между указанными двумя электродами (3); определения модели пространства состояний, которая определяет соотношения между электропроводностью, напряжением и током в целевом объеме (2) и которая также определяет эволюцию электропроводности как функцию времени; сравнения токов и/или напряжений, в соответствии с моделью пространства состояний, с приложенными и измеренными значениями; и модификации, по мере необходимости, модели пространства состояний, чтобы уменьшить различия между вычисленными и измеренными результатами. В соответствии с настоящим изобретением электроды (3) расположены, по существу, в одной плоскости (4); а модель пространства состояний задают таким образом, чтобы она включала нестационарное поле течения массового потока внутри целевого объема (2).
