Font requirements for doctoral thesis:
Numbers with more than 5 digits, such as 1 and mantissa "0", can be rewritten as numbers in thousands and billions. Under normal circumstances, it is not allowed to take ten, hundreds, thousands, hundreds of thousands, millions, tens of millions, billions, billions, billions, etc. As a unit (except for prefixes of hundreds, thousands and trillions).

3. The numerical value is modified according to GB 8 170- 1987 "Rules for Numerical Value Modification", and its concise formula is "4+6 enters 5 to see the right, after 5, there are numbers going up, mantissa is 0 to see the left, odd numbers enter left and even numbers are discarded".
4. Multiply the numerical value by the length unit, and the unit after each numerical value cannot be omitted. For example, 5 cm×8 cm× 10 cm cannot be written as 5x8×10cm or 5x8×10cm3.
5. When the measurement units of a series of values are the same, the unit symbol can only be written after the last 1 digit. For example: 60,80, 100 mol/L. It is unnecessary to write 60 mol/L, 80 mol/L, 100 mol/L. ..
6. When the scores are arranged by 1 line, the semicolon is diagonal.
