找到一篇巴比伦塔的还原教程,可惜是英文的~

不知道巴比伦塔是什么的请看看这个:http://bbs.mf8-china.com/viewthread.php?tid=58038

给大家看看:
(貌似是两种解法)

Solution 1:
It can be solved in layers, disc by disc from the bottom up starting with the brightest colours. Start by pushing in one of the balls to create a gap.
Phase 1: How to solve a disc.

Find a ball that belongs in the disc but which is not in the correct position.
If the ball is in the disc already, just in the wrong place then move it to the layer above:
1. Shift balls down to get the gap in one of the discs above the ball.
2. Rotate discs to place the gap above the ball in the same column.
3. Shift the ball up.
4. Rotate the ball to a different column and drop another ball in the gap.
If the ball does not lie one layer immediately above the disc being solved then:
1. Rotate a disc to place the gap in a different column to the ball.
2. Shift the column up/down to get the gap in the disc below the ball.
3. Rotate discs to place the gap beneath the ball.
4. Shift the ball down.
Repeat until the piece lies in the layer immediately above the disc being solved.
Place the piece correctly as follows:
1. Rotate discs to place the piece in a different column than its destination, and the gap in the destination column.
2. Shift the column up/down to get the gap in the disc below the piece.
3. Rotate discs to place the gap beneath the piece.
4. Shift the piece down.
Note the similarity to step b.
Repeat a-d above until the whole disc is solved.
The method above can solve any of the layers of the tower, except for the top one. There are a few minor differences when solving the first layer because of the spring mechanism that creates the gap. First push in one ball to create the gap. Solve the ball on the other side. Then pull out the first ball and push in the solved one. Now continue the method as above.

Phase 2: Solve all but top disc.
Repeat phase 1 with the remaining discs until everything except the last disc is solved.

Phase 3: Solve top disc.

If the permutation of the balls and the gap (where the gap belongs in the column of the pushed-in ball) is odd, then rotate the disc one step, i.e. 1/6 of a turn.
Rotate the top disc an even number of steps (i.e. 1/3 turn) to put as many pieces correct as possible.
To solve the remaining balls, the following sequences will come in handy.
Let a and A denote the top balls of one column, b and B those of another column etc., and let Z be top ball of the column with the gap. The following diagrams show how certain positions can be solved:
      B A   BaA   Ba   Bab    ab  Aab  A b  ABb  AB
      abZ    bZ   AbZ  A Z   ABZ   BZ  aBZ  a Z  abZ

      BCA   BCAa   CAa  cCAa  c Aa  cBAa  cB a  cBCa   BCa  ABCa  ABC
      abcZ   bcZ  BbcZ  Bb Z  BbCZ   bCZ  AbCZ  Ab Z  AbcZ   bcZ  abcZ
Both of these cycle three things in the top disc, the first cycles two balls and the gap, the second three balls. Note that the relevant columns need not be adjacent nor in the order as shown here. Simply mentally name the columns a, b, Z (and c) and move the balls between these columns as shown above wherever they may physically be on the puzzle.
From step a, the balls have an even permutation, so these 3-cycles suffice to solve it. If you end up with exactly two balls swapped (or only a ball and the gap swapped) then it was an odd permutation so go back to step a to rectify it.
Solution 2:
It can also be solved in columns.

Phase 1: Place each colour into a column.
This phase is virtually the same as solving the Whippit puzzle.

Decide which colours the columns will have. To speed things up, you could rotate some discs to partly solve some columns already.
Push in a ball to create a gap.
Look at the column containing the gap, and determine which colour the column has.
Find a piece of the required colour in a different column. If there are none, and the columns are not yet one colour each then find any piece on the puzzle that is incorrect.
Slide pieces in the column up or down until the gap is in a layer next to the layer that contains the piece.
Rotate the layer with the gap until it lies above or below the piece.
Slide the piece up or down into the gap.
Rotate the layer back to its original position, which brings the piece into the column as required.
Repeat steps b-g until the puzzle is solved. At some point you should also let out the pushed in ball, and push in the ball on the other side. Do this any time that the bottom two balls of the column on the other side have been solved.
Note that in practice it is quicker to move not just the one layer, but all the layers above/below it as well.

Phase 2: Order each colour, except for top two layers.

There now follows a method of moving a ball up two layers, passing over two balls which drop down one layer. This is a 3-cycle.
First create a gap in any other column.
Bring the gap to the layer above the ball to move.
Use the method of phase 1 to bring the ball to the position of the gap. (Rotate the gap above the ball, move ball up, rotate disc back again.)
Bring the gap to the layer above the ball to move.
Again insert the ball into the position where the gap is.
Use steps b-e to place the correct 4 balls in the bottom 4 positions of the column. Note that the top two balls may now either be correct, or they need to be swapped.
Now get rid of the gap by releasing the pushed in ball.
Solve each column in the same way.
Phase 3: Swap the top two balls of any columns that need it.

If there is an odd number of columns that need their top balls swapped, then turn the top layer 60 degrees (i.e. one step) and go back to phase 1. It will not take long to fix this problem since the bottom 4 layers need not be disturbed.
If there are two or more columns that need swaps, then choose any two of them, and create a gap in a third column.
Do the sequence shown in the following diagrams.
      ab   abA  a A  aBA  aB   aBb   Bb  ABb  AB
      ABZ   BZ  bBZ  b Z  bAZ   AZ  aAZ  a Z  abZ
      
Note that the relevant columns need not be adjacent nor in the order shown in these diagrams. Simply mentally name the columns a, b, and Z and move the balls between these columns as shown above wherever they may physically be on the puzzle.
Repeat steps b-c until the puzzle is solved.

其實唔洗教程,用借位既方法係咁推,係咁轉,係咁推,係咁轉就得架喇,好容易架,自己研究吓就搞掂

你是能看懂没实物。我是有实物看不懂。
