Sample 2 is moved translationally and rotationally in such a way that its axis is parallel to the axis of the leading screws I. The size of the metal balls is chosen so that contact with the surface of sample 2 at one point is ensured.
Таким образом, при перемещении образца по спирали получают непрерывные диаграммы распределени электрического сопротивлени за счет посто нного контакта электродов в виде металлических щариков с образцом в процессе измерени . В случае необходимости путем усреднени таких диаграмм получают среднее значение электросопротивлени дл всего образца.Thus, when the sample is moved in a spiral, continuous diagrams of the electrical resistance distribution are obtained due to the constant contact of the electrodes in the form of metal balls with the sample during the measurement process. If necessary, an average of the electrical resistivity for the entire sample is obtained by averaging such diagrams.
