Attention points for proofreading technology reading materials in printing 2. Symbols 【 Buke printing factory 】

Symbols in science and technology books are an organic part of characters, and there are many commonly used symbols in mathematics, physics, chemistry, biology, meteorology and geology. Some of them have only slight differences, which can easily make mistakes during typesetting. However, if you relax a bit during proofreading, it can also lead to confusion and missing samples. For example, the symbols "∠ (angle)" and "<(less than)" are often difficult to immediately determine in handwritten manuscripts, and need to be distinguished from each other in terms of textual meaning. Another example is "↓ (precipitation)" (gas) "in the chemical symbol,">(greater than) "and"<(less than) "in the mathematical symbol. They have the same shape, but are opposite in direction. If they are confused, their meaning will be opposite. Some symbols are similar to certain punctuation points, but their positions are different, which should also be noted. For example, the "." sign, when used as a period, is positioned lower, while when used as a temperature and angle symbol, it is positioned higher. Improper layout can result in two different meanings.

There are quite a few corner markers in science and technology reading materials, and when proofreading, it is necessary to verify them according to the original manuscript. First of all, pay attention to its position. Some are in the upper right corner, while others are in the lower right corner. You cannot get the position wrong. Some corner markers are more complex, such as Ax1, and attention should be paid to their font sizes (one size smaller each level), fonts (positive, oblique), and so on.
