Description
отношению диаметра отдельной трубки к ее длине. При этом угле свет практически не попадает на фотоэлемент.the ratio of the diameter of a separate tube to its length. At this angle, the light practically does not reach the photocell.
Таким образом, диапазон углов, которые можно измер ть с помощью этого прибора, можно мен ть, мен отношение диаметра к длине.Thus, the range of angles that can be measured with this instrument can be changed by changing the ratio of diameter to length.
Этого можно достигнуть или путем замены одного затен ющего приспособлени другим, или сделав трубки телескопически раздвигающимис . Ток фотоэлемента измер етс гальванометром на поверхности земли и может служить мерой угла отклонени от вертикали.This can be achieved either by replacing one shading device with another, or by making the tubes telescopically extendable. The photocell current is measured by a galvanometer on the surface of the earth and can serve as a measure of the angle of deviation from the vertical.
Чем -уже трубки, тем чувствительнее прибор и тем меньше сказываетс вли ние неоднородности светового пучка и поверхности фотоэлемента .The worse the tube, the more sensitive the device and the less the effect of the heterogeneity of the light beam and the photocell surface.
