Embodiment

Below in conjunction with drawings and Examples, the invention will be further described.

The moon has that the moon is round and then crescented, lack by the moon and have top to lack with scarce below, the moon is round and then crescented every 29.5 days one-periods, the mankind can only see the plane picture that the moon is round and then crescented on earth, can't see the sun, the earth and moon three's spatial relation, the mankind will with moon space flight contact, must fully understand the earth, the two spatial relation of the moon.

Referring to Fig. 1-Fig. 3, this moon motion model, comprises bearing 1, on bearing 1, be provided with a coupling shaft 2, coupling shaft 2 two ends connect respectively bearing 1 and geoid 6, and coupling shaft 2 middle parts are rotatably connected to spheroid 5 in January, on bearing 1, be also provided with can drive that moon spheroid 5 rotates shake the hand 3.On coupling shaft 2, be rotatably connected to sleeve 7, be provided with vertical with it support bar 4 on sleeve 7, a month spheroid 5 is positioned on the end of support bar 4.Sleeve 7 and shaking the hand between 3 by gear 8 transmissions.

Wherein, month spheroid 5 be can be reflective spheroid, its diameter is the half of support bar 4 length.The circular slab of geoid 6 for placing vertically, its radius is consistent with the length of support bar 4.The center of circle of the center of circle of geoid 6 and rotating shaft 2 is in same level, and the center of circle of geoid 6 is positioned at the right side in the center of circle of rotating shaft 2, and the distance in two centers of circle is consistent with the radius of month spheroid 5.Geoid 6 is placed in the front of moon spheroid 5 and bearing 1.

This moon motion model, simulates the motion state of the moon, accurately gives expression to moon moon circle, month scarce variation when operation, and the phases of the moon of upper and lower string.Painted black on geoid 6, the circular edges of geoid 6, every 12 degree, engrave a scale mark again, every lattice scale mark represents the moon stroke in January, in the horizontal scale of the right, be labeled as the junior one, then put on clockwise the mark (being simplified to 30 days 29.5 days) that represents month 30 days, then south poles on the azimuth mark of the corresponding earth.

This moon motion model is finally placed in darkroom, puts thereafter and establishes single light source, by the handle 3 at shake moon motion model rear, can make moon spheroid 5 clockwise rotate, thereby can be observed the phases of the moon of every day.As month spheroid 5 is shaken to the mark to the junior one, the moon, spheroid 5 was whole to be blocked, and the phases of the moon be cannot see; And for example, moon spheroid 5 mark of shaking to 15, within whole month, spheroid 5 is all visible, and the phases of the moon be circle.

Referring to Fig. 4, the circle of the moon lacks and changes principle: at nature under strong light source irradiates, any object side backlight has shadow one, become radioactivity to expanding at a distance, this road shadow projects far away just larger, the earth is also one shadow back to the one side of the sun, this road shadow projects an astronomical unit, the diameter of shadow is exactly the twice of ground bulb diameter, the moon is apart from 380,000 kilometers of the earth, that the sun is apart from approximately 1/400th of the earth, 12756 kilometers of the diameters of the earth, the shadow of the earth projects 12788 kilometers of the diameters of lunar orbit shadow, than the diameter of the earth large 32 kilometers.

In Chinese patent literature CN101373564, disclosing the solar system is a clavate whirlpool galaxy, as shown in Figure 5, comprised the sun, planet, fixed star, the earth and the moon, the earth runs to the summer solstice, the sun, the earth runs to winter solstice three points and becomes isometric V font, the earth runs to day in the Spring Equinox, the sun, the earth runs to day in the Autumnal Equinox three points and becomes not isometric V font, day in the Spring Equinox, the earth was nearest apart from the sun, day in the Autumnal Equinox earth apart from the sun farthest, day in the beginning of spring and day in the Beginning of summer the earth equal apart from the sun, day in the beginning of autumn and day in the Beginning of Winter the earth equal apart from the sun, day in the beginning of autumn and day in the Beginning of Winter than day in the beginning of spring and day in the Beginning of summer the earth far away apart from the sun.

The thermal current (solar wind) that the solar system relies on sun burning cosmic material to produce drives numerous celestial bodies to become a clavate whirlpool galaxy.The earth is synchronizeed and is revolved round the sun with numerous celestial bodies, the earth is due to bulky, under powerful air-flow (solar wind) effect, the earth forms an air-flow whirlpool back to solar direction, the moon is at this air-flow whirlpool edge motion, the air-flow whirlpool at the earth back side advances with revolution of earth, the moon is also followed revolution of earth at air-flow whirlpool and is advanced, air-flow whirlpool diameter equals the diameter of the earth, the moon is at this air-flow whirlpool edge motion, circle exposes outside the moon half, the shadow of the earth is not the central point that projects air-flow whirlpool, but project eccentric half moon of air-flow whirlpool, when the formation moon runs to air-flow whirlpool one end, the whole moon is all subject to solar radiation, the mankind see the whole moon, when the moon runs to the air-flow whirlpool other end, the whole moon does not all have solar radiation, the mankind can't see the moon, or see the moon of the first half or the latter half.

Because the earth is one week from west to east every day, the sun, the earth, the moon point-blank, so the Sun and the Moon all wants east-west direction to exchange one time every day, the moon is always all in the position operation of the back of the body day of the earth, in the Korean and Japanese direction of the earth, do not pick up the formation solar eclipse of keeping off the sunshine, as a same reason, the sunlight that the earth blocks the moon is exactly before and after the junior one monthly, just cannot see the moon on earth, so the relation that lunar eclipse neither the earth.

The sun is in the front of the earth, the moon is in the back of the earth, why appear at simultaneously people in the eyes? will look for answer from the mankind's eyes visual angle, the mankind's about 120 degree in eyes visual angle, when the mankind's eyes are looked squarely, visual angle is below local horizon, see when the sun is gone up people from local horizon labour contractor lift, about 60 degree have been raised at visual angle, the mankind's eyes visual angle is 120 degree more than local horizon, the mankind stand and become 90 degree with local horizon, there has been the visual angle of 30 degree at the mankind's eyes visual angle to back, along with earth rotation sun angle raises, the sun, beholder, three points of the moon become V font, sun one end is long, moon one end is short, the sun, the moon has just entered in the unidirectional sight line of beholder simultaneously.

The moon also has the tropic, the Northern Hemisphere lunar calendar 15 is before and after the summer solstice, evening, ten two moon were in southern minimum altitude, and the Southern Hemisphere lunar calendar 15 is before and after the summer solstice, and evening, ten two moon were in northern maximum height, the Northern Hemisphere lunar calendar 15 is before and after the winter solstice, evening, ten two moon were in maximum height, and the Southern Hemisphere lunar calendar 15 is before and after the winter solstice, and evening, ten two moon were in northern minimum altitude, because the moon is in the opposite direction of the sun, so moon height is contrary with altitude of the sun.The moon in season that the sun is high is just low, and the moon in season that the sun is low is just high, and this phenomenon is more easily found in high latitude area.

The recursion period of the moon is equally in " summer solstice " and " winter solstice ", and returning angle is 23.5 degree equally, and " summer solstice " and " winter solstice " aims at the lunar calendar bright ability in ten Mays and return at this line, and major part has all returned in advance, but can not exceed this line, returns.Live in the people in the Northern Hemisphere as long as paying attention to observation will find, the bent moon of seeing the beginning of the month moves day by day southwards, and it is large that bent moon becomes day by day, to the ten Mays circles moon in the south of this month, just move southwards day by day, circle month diminishes into bent moon day by day, and the one-period of moon operation that Here it is changes.

At the lunar calendar, people in morning in the last ten-days period can see the sun, the moon appears on sky simultaneously, actually the moon at the earth front or the rear to the sun? believe that a lot of people have been cheated by the eyes of oneself, what the lunar calendar was seen the last ten-days period is a bent moon, moon major part is covered with by a shadow, can only there is fraction to shine upon reflective, at the earth, can only see the sub-fraction that the moon is reflective, remaining has all been covered by this shadow, any object back side under strong illumination has shadow one, larger its shadow of object is just larger, the solar system is no exception also, each celestial body back side under solar light irradiation has shadow one, earth back side under solar light irradiation also has shadow one, having other celestial body to be covered by earth shadow just can not reflected sunlight, this celestial body will disappear, the earth shadow that this celestial body diameter is large covers remaining, equally can reflected sunlight.

The moon is just in time in the operation of the back of the earth, the moon does not have rotation, only has revolution, and the moon approximately 29.5 ruler of heaven circle, the shadow of the earth is just in time at the eccentric position of moon revolution track, the whole moon of the lunar calendar junior one is covered by earth shadow, at the earth, just can't see the moon, and the whole moon of the lunar calendar 15 has been walked out the shadow of the earth, at the earth, just seen a complete moon, lunar calendar the eighth day of lunar month and 22, earth shadow has covered approximately half moon, at the earth, just sees and winding up and the moon of lower edge.

People watch the astrology on earth, the moon resembles and all can be subject to horizontal restriction, the earth is rotation from West to East, the earth is just between the sun and the moon, earth rotation the Sun and the Moon will be exchanged once at the east-west direction of the earth every day, when observer position, it is exactly the morning of every day that the sun rises in local horizon, every day time that the moon rises is all different, see that first half of the month of the time lunar calendar of the moon is all in before midnight, the second half of the month, is all in the time after midnight, reason be exactly first half of the month the moon be direction operation outside Earth's orbit, when the earth forwards to towards the moon, the moon just rises in local horizon, the sun does not also fall and just there will be the west sun chronometer phenomenon of the moon in the east, because the moon rises to such an extent that early arrived west to falling local horizon, it is also not bright, so just seen the moon in before midnight first half of the month.

When the north that the moon runs to the earth to, the moon will be exactly 15 of the lunar calendar completely under the irradiation of sunlight, the second half of the month that the capable center position to Earth's orbit of the moon is exactly the lunar calendar, the position of the moon is not also arrived in the local horizon in sun east after the local horizon in west disappears, to just can occur in local horizon in the Orient through the moon after a while, after the sun rises in the Orient, the moon is also more than the local horizon in west, people have just seen sun west, the east moon, so moon the second half of the month is but to appear at the time after midnight.
