Preliminary test of the induced polarization method in 1∶50000 reconnaissance in a metallogenic belt-example from the demonstration of 1∶50000 rapid electric reconnaissance in the East Tianshan copper metallogenic belt, Xinjiang
In methylal the rise time constant of light emission of single avalanches is compared with the rise time constant of the electron production measured by the electrical method.
In the present study, we examined the ciliary activity of the nasal mucosa of 35 patients with nasal allergies by using the photo-electric method of Ohashi and Nakai to better understand the non-allergic pathologies present.
The nature of the conductivity was studied over the whole range of Li2S concentrations using Tubandt's procedure, and the contribution of electronic component to the total electrical conductivity was examined by Liang-Wagner's polarization method.
It is shown that such composite systems observed by the interference-polarization method for the case of crossed Nicol prisms produce figures in the form of a system of concentric light and dark rings, in the center of which there is a dark cross.
An attempt is made in the present study to investigate the extent of the influence of structures such as fractures and thereby delineate the nature of subsurface lithology with the help of an electrical resistivity method.
