The Treatment of "Leaves and Tail" in the Layout of Books and Periodicals II

2 Digital layout left empty processing

In science and technology layouts, there are many formulas, and the difficulty of typesetting is also increased. Especially when there are rows of rows, there are often left-tailed blanks. How to deal with this kind of leaving tail space?

First of all, we should grasp the features of digital formulas and the rules of digital typesetting and digital typesetting, and then perform digital typesetting. In the event of a long style, it will be split by the number of lines in a long line, that is: 1 first remove =, nickname; 2 then split +, - -; 3 last split ×, nickname.

Typesetting method: 1 split "+" sign up and down; 2+, -, ×, apostrophe indentation "=" 1 word distance.

If there is text before the formula, then the word processing rule before the formula:

1) When the formula before the text ≥ 6 words, the formula should be another line, and center row;

2) When the text before the formula is less than 6 words: a. The formula is arranged after the text, but the formula is to be centered; b. The formula has a pattern code, and the formula must be centered on another row. Formula layout is standardized.

Secondly, in the layout where leaving tails are empty, the left-end space can be handled by increasing or decreasing the line spacing or the line spacing in the formula. The annotation commands used are [HJ], [KH]. See Figure 3.

If the formula in the above layout is shifted down, the word space should be increased by one and a half words. When the formula is moved upwards, the word size should be reduced, that is, the spacing of the one-word distance.

3 Treatment of chemical layout

The layout of chemical layouts is more complex, and there are more annotation command parameters used, especially the layout of ring structures. This type of layout is also prone to stay empty, how to deal with this kind of left blank layout? The method is "rearranging." The so-called "re-arrangement" is to change the form of the ring structure, but its chemical nature does not change the typesetting. When composing, you should master:

1) According to the status of void at the end of the edition;
2) The orientation of chemical bonds (Z, Y, S, X, ZS, ZX, YS, YX);
3) Straight bonds, "C", "CH" atoms, and atom groups can be omitted;
4) Self test.

If the phthalic anhydride on the manuscript is 10 characters high, it must be at the end of the edition, but the end of the edition is only 5 characters high, obviously not in the list. If you place it on the next page, the page will be empty. We use the "re-arrangement" method to change the structure, and the result is:

The annotation commands used are [JG], [LJ], [JJ], [ZJ].
