How many pictures can be drawn on a piece of paper. A master plan can be drawn on several drawings, but it is necessary to ensure that the drawings on each drawing are independent. When all the drawings are combined to form a complete master plan, they do not affect each other's clarity.
4. There should be no border around the attached drawings. If there are more than two attached drawings, they shall be numbered with Arabic numerals, and the word "Figure" shall be added before the number, as shown in Figure 1 and Figure 2. This number should be marked directly below the corresponding drawing. The attached drawings should be drawn as vertically as possible on the drawings and clearly separated from each other. Marks shall be numbered with Arabic numerals.
5. The same drawings should be drawn at the same scale. The appended drawings shall have no other comments except necessary words. The text in the appended drawings should be Chinese, and the original text can be marked with brackets if necessary.

If the attached abstract obviously fails to explain the main technical features of the technical scheme of the invention, or the attached abstract is not one of the drawings in the specification, the examiner may notify the applicant to make corrections, or designate a copy ex officio, and notify the applicant.
2. The size and clarity of the attached drawings shall ensure that when the drawings are reduced to 4cm× 6cm, all the details in the drawings can still be clearly distinguished.
3. The abstract can contain the chemical formula that can best explain the invention, and this chemical formula can be regarded as an abstract diagram.
