Can you briefly introduce it, there are many words, and the grid can t be lowered

The rest of 2012 is currently wonderful

November 14 Total solar eclipse in the Southern Hemisphere.

December 3 Jupiter at opposition to celebrate the New Year.

December 14 Geminid meteor shower on a moonless night.

Common astronomical phenomena.

List. Solar eclipses: total solar eclipse, partial solar eclipse, and annular solar eclipse.

Lunar eclipses: total lunar eclipse and partial lunar eclipse, penumbral lunar eclipse.

Transit: An inner planetary phenomenon that can be seen on Earth, such as the transit of Mercury and the transit of Venus.

Conjunction: A conjunction: A conjunction, that is, a celestial body that sees its position in the same direction as the Sun (defined by the same longitude as the Yellow Longitude), at this time the celestial body rises and sets at the same time as the Sun, and the celestial body cannot be seen under the influence of the Sun.

Opposition: With the Earth as the center, when the planet moves in the opposite direction to the Sun (strictly defined as the 180 degrees difference in ecliptic longitude), the planet rises eastward after sunset, and the sunrise occurs when the planet falls to the horizon, so the celestial body can be seen all night, and if the opposition is a planet or asteroid, it is also the time when the planet is brightest and most suitable for observation.

Planetary alignment: A planetary alignment is defined as a planet whose positions are all in a general direction (within a small angle), and is also defined as a circle centered on the sun and several planets within a certain minimum degree (e.g., the nine-star alignment in 1982). The planetary alignment is said to be the cause of gravitational imbalance and natural disasters, but this is of course a claim that has no scientific basis until now.

There is another theory: three (or more) of the five planets that can be seen with the naked eye appear in the same direction in the early morning or dusk in a period of time (two or three days to half a month). For example, in May 2002, the Five Stars (which appeared in the West after dusk).

Star occultation: mostly lunar occultation, planetary occultation, asteroid occultation, planetary occultation of their satellites, etc.; There are rare lunar occultations, planetary occultations, comet occultations, etc., and solar and lunar eclipses are also a type of occultation.

The celestial phenomena that can be ** include:

The phenomenon of occultation between celestial bodies and celestial bodies, mainly such as "eclipse", "occultation" and "ling".

Predict the position of various celestial bodies, such as the sun, moon, planets, planetary moons, and asteroids.

The replacement of the relative positions of celestial bodies with the Earth and the Sun.

The relative position of the Moon and the Earth: the first quarter - the first quarter - the second quarter - the second quarter - the far (near) position of the Moon.

Inner planetary apparent motion: upper conjunction—eastern elongation—stay—inner conjunction—inner conjunction—stay—western elongation—upper conjunction

Apparent motion of outer planets (asteroids): stay-opposition-stay-conjunction.

The comet is close to the Sun, the Earth.

Meteor swarms variable stars are extremely small and extremely luminous.

Sudden and unpredictable celestial phenomena such as anomalies on the surface of planets (such as Martian dust storms, changes in Jupiter's cloud belts, Saturn's white spots), meteors, novae, supernovae, auroras, zodiacal lights, sunshine and even comets hitting Jupiter, meteors hitting the moon; In the past decade, artificial satellites such as Iridium satellites and space stations (or with flashes, which may approach or visually pass by the surface of celestial bodies) are not strictly astronomical phenomena, but because of the apparent position and time of their appearance and flashes can be calculated according to their orbits, they are also one of the objects of observation by astronomy enthusiasts.

Probably not, at least not the OfficeXP I'm using now. The WPS2000 you used to use in the past is fine, you can try it.

The skin and dust of the Dao clan are the same as the disadvantages of the banquet.

You can use the "Format Brush" of the toolbar to solve these inexplicable problems, the method is: first select the cells that want to achieve that effect in the future, that is, the "source" cell, and then double-click the "Format Brush" of the toolbar, and then the cursor becomes a cursor with a small brush, and then select those cells that cannot change the font, you can use the drag approaching method, and press the esc key to end the selection after selection!

Vertical center, right-click to format the cell, align the tab Vertical and select the center is OK.

Right-click to format cells, align tabs, and you can set.

You still click on your area, go in and see if it works, if it doesn't work, log in again, and if it doesn't work, go down again, and give you **.

It's a graphics card problem, install a driver wizard and the driver of the next graphics card.

No problem

Don't forget to ask questions.
