Description

Предлагаетс  нагл дное учебное пособие дл  демонстрации способа определени  широты места по положеннро Пол рной звезды.An advanced tutorial is offered to demonstrate how to determine the latitude of the location of the Polar Star.

Отличительна  особенность пособи  состоит в том, что оно выполнено в виде плоского экрана, несзщего изображение земного шара и р д параллельных его оси линий, представл ющих лзчи пол рной звезды, и установленной поворотно в центре окружности изображени  земного шара линейки, снабженной на конце транспортиром н поворотно укрен епной в центре его з/казательной стрелкой.A distinctive feature of the manual is that it is made in the form of a flat screen, not depicting the image of the globe and a series of lines parallel to its axis representing the slings of a polar star, and a ruler installed at the end of the circle of the image of the globe the rotary ukrenna epna in the center of his s / significant arrow.

На фиг. 1 схематически изображен общий вид пособи ; на фиг. 2- общий вид транспортира поворотной указательной стрелкой; на фиг. 3- вид шкалы щирот.FIG. 1 schematically shows a general view of the manual; in fig. 2- a general view of the protractor with a turning index arrow; in fig. 3 - view of the scale of schirot.

Пособие предназначено дл  объ снени  способа определени  nii-ipoты места но Пол рной звезде. Оно состоит из начерченного на бумаге экрана 1, круга изобра -сающего земной шар и линейки 2, поворотной на оси, закрепленной в центре круга. Па концелинейки помещен транспортир 3f градуснр 1ми делени .ми и вращающейс  стрелкой 4 из проволоки , укрепленной в его центре. На ножке угломера проводитс  пр ма  лини  5 от центра круга к центру транспортира. Стрелка 4 и линейка 2 должны туго вращатьс  вокруг своих осей дл  того, чтобы их можно было устанавливать на любой точке окружности. Экран наклеиваетс  на толстый картон или фанеру. Лучи 6 Пол рной звезды изображаютс  в виде параллельных линий, идунлих к проведенным на круге параллел м северного полушари .The manual is intended to explain the method for determining the nii-ipots of a place in the Polar Star. It consists of a screen 1 drawn on paper, a circle depicting the globe and a ruler 2 rotating on an axis fixed in the center of the circle. A connector is placed at the end of the line with a 3f degree protractor in 1 divisions and a rotating arrow 4 made of wire reinforced in its center. On the leg of the protractor is held straight line 5 from the center of the circle to the center of the protractor. Arrow 4 and ruler 2 must be tightly rotated around their axes so that they can be mounted on any point of the circle. The screen is glued to a thick cardboard or plywood. Rays 6 of a polar star are depicted in the form of parallel lines, along the lines drawn on a circle parallel to the m of the northern hemisphere.

На соответствующей широте отмечаетс  кружком данный населенный пункт и надписываетс . Названи  щирот помещаютс  наверху прибора под откидьгвающейс  планочкой 7. Прп демонстрировании ставитс  условие, что благодар  больщому рассто гппо между землей и Пол рной звездой, ее лучи, падающие на землю, можно считать параллельными . Объ сн етс  устройство и назначение линейки и транспортира. Затем транспортир устанавливают на «Северном полюсе прибора и измер ют высоту Пол рной звезды. Стрелка транснортира показывает 90°.At the appropriate latitude, this locality is marked with a circle and is inscribed. The names of the chirot are placed at the top of the device under the folding plank 7. The display demonstrates that, due to the large distance between the earth and the polar star, its rays falling on the earth can be considered parallel. The design and purpose of the ruler and protractor is explained. Then the protractor is mounted on the "North Pole of the instrument and the height of the Polar Star is measured. The transnortyr arrow shows 90 °.
