In some specific situations, such as when children are studying math or counting votes, notation can be used to help them understand. For example, when children learn to count, they can count one by one with a pen or finger, make a mark on the related things every time they count, and finally count how many marks they have made to know the total.
The main function of notation is to help beginners understand the concept of number, and also to help them remember and understand mathematical formulas.
Marking method is a useful tool, which can help us better understand and master mathematical knowledge.
Application of marking method
1, Biology and Biomedicine: In the field of biology and biomedicine, markers are often used to track the interaction of biomolecules (such as protein, nucleic acid and sugar).
For example, radioisotope labeling technology can be used to study the metabolic process and metabolites of labeled substances in vivo. In addition, the enzyme-labeled immunoassay technology combines the valence of antigen, antibody or hapten with peroxidase to form a complex, which not only retains the decisive factor of immune reactant (that is, the specificity of immune reaction), but also does not affect the catalytic activity of enzyme, so that the tested compounds can be identified and quantified by the products generated by the reaction between enzyme and substrate after immune reaction.
2. Geology: In geology, labeling is often used to identify and measure elements and isotopes in rocks and ores. For example, by measuring the specific isotope ratio in rocks, it can help to determine the age, source and formation process of rocks.
3. Chemistry: In chemistry, labels are often used to track the progress of chemical reactions. For example, specific labels (such as dyes or tracers) can be added to a chemical reaction to track the progress of the reaction.
Generally speaking, labeling has its applications in various fields, which can effectively help people better understand and master various complex processes and phenomena.
