In one embodiment, the source-bound day distance measurements may be made, as shown in FIG. 11. When the moon is just half lighted (the upper crescent moon or the lower crescent moon) on the earth, the earth-the moon-the sun is at a right angle, the angular distance between the sun and the moon in the sky can be measured, and the sun-earth distance can be calculated through the earth-moon distance. Specifically, as shown in fig. 12, a small hole is drilled in the middle of two hollow tubes, and the two hollow tubes are strung together by a thin nail to measure the included angle between the sun and the moon. The moon can be aimed through the hollow tube, but when another hollow tube is aimed at the sun, the sun can not be seen by eyes at all, so that the burn is prevented, the shadow of the hollow tube can be adjusted to be opposite to a piece of paper, and the moon is aimed when the shadow becomes a minimum point. And measuring the included angle, and obtaining the distance between the day and the ground by utilizing a cosine formula.
SE＝ME/cos(δ)
The embodiment has the advantages that students can feel farther distances such as Japanese click and karst by meditation and further distances from Shanghai to Hangzhou and other familiar distances from home and school, and then expand the distances to earth, earth and moon, earth and sun, and the distances to earth and sun are expanded to half year distance and diameter of earth revolution orbit, and the distance to celestial bodies forms 1 arc second parallax on celestial bodies, which is equivalent to 3.26 light years away from the sun, so that the space sense is further expanded, the universe view and world view are gradually established, the head is lowered, and the peace and confidence of starry sky is formed.
As a further improvement of the above embodiment, in an embodiment, the virtual astronomical phenomena table can be arranged on the top of a school, in addition to the top of a building, in a waiting bird scenic spot, for watching stars at night, for watching birds at day time, and for paying.
According to the longitude, the latitude and the altitude and the time, the position of the sun on the celestial sphere is calculated, the protection range of the equatorial telescope is dynamically updated according to the visual field of the second ocular lens, and the sun is prevented from imaging on the second ocular lens and burning the second ocular lens. Because the second eyepiece visual field is far greater than first eyepiece, as long as the sun can not get into the second eyepiece, also can not get into first eyepiece naturally. This function is particularly important when used to view birds on a sunny day.
As a further improvement of the above embodiment, in an embodiment, the system further includes a computer room in a school, and a computer in the computer room can be connected to a specific website, so as to perform learning and assessment on knowledge and skills. By limiting the access resources, the computer can return to the positive role in the education and teaching, and children are prevented from being immersed in the game.
As a further improvement of the above embodiment, in one embodiment, the system may be connected to a knowledge website, including knowledge of mathematics, mechanics, etc., knowledge of aviation, knowledge of space, geophysical, celestial physics, etc. The benefit of doing so is that the efficiency of learning knowledge is improved through computer assistance and interest-driven by students.
