Description
стойнйе определ ют по положению второй точки относительно делений этой шкалы.The number is determined by the position of the second point relative to the divisions of this scale.
При определении географических координат полуоси 11 линейки 9 ввод т в отверсти глобуса 1, наход щиес на его полюсах . Затем глобус 1 устанавливают на кольцо 5 таким образом, чтобы линейка 9 своими торцами попала в пр моугольные пазы 8.In determining the geographic coordinates of the semi-axis 11, the ruler 9 is inserted into the apertures of the globe 1 located at its poles. Then, the globe 1 is mounted on the ring 5 so that the ruler 9 with its ends falls into the rectangular grooves 8.
Вращением глобуса 1 на образовавшейс оси заданную к определению географических координат точку совмещают с визиром 13 линейки 9 и по градусной сетке на экваторе глобуса 1 определ ют долготу. Затем плавным перемещением ползунка 10 его визир 14 также совмещают с заданной географической точкой и по шкале 12 линейки 9 определ ют широту.By rotating the globe 1 on the formed axis, the point assigned to the definition of geographic coordinates is aligned with the sight 13 of the ruler 9 and the longitude is determined by the degree grid at the equator of the globe 1. Then, by smoothly moving the slider 10, its reamer 14 is also aligned with a given geographic point, and on a scale of 12 of the ruler 9, the latitude is determined.
При нахождении географической точки по заданным координатам работа проводитс в обратном пор дке. Перемеща ползунок 10 вдоль линейки 9 по шкале 12 визиром 14 отмечают заданную координату широты. Вращением глобуса 1 по его градусной сетке на экваторе наход т и совмещают с визиром 13 линейки 9 заданную координату долготы. Искомую географическую точку читают в перекрестье визиров 13 и 14.When a geographic point is found at given coordinates, the work is carried out in the reverse order. Moving the slider 10 along the ruler 9 on a scale of 12 vizir 14 mark the given latitude coordinate. By rotating the globe 1 along its degree grid at the equator, the desired longitude coordinate is found and aligns with the vizier 13 of the ruler 9. The desired geographical point is read in the crosshairs of the Vizier 13 and 14.
Дл демонстрации наклона Земли в наклонное отверстие -бобышки 15 помещают съемную направл ющую ось 16. Глобус 1 устанавливают в шариковых опорах 4 стоек 3 так, чтобы ось 16 вошла в отверстие его южного полюса.To demonstrate the inclination of the Earth, a removable guide axis 16 is placed in the inclined hole of the base 15. Globe 1 is installed in ball bearings 4 racks 3 so that axis 16 fits into its south pole hole.
