2. Science generally refers to natural science, applied science and mathematical logic. Science includes mathematics, physics, chemistry, biological science, astronomy, atmospheric science, electronic information science and environmental science. The goal of science training is to engage in scientific research, teaching, technology development and related management. As far as the development of higher education in China is concerned, laying a good foundation for undergraduate education is increasingly recognized by the society.

3. Engineering is a discipline developed by applying the principles of basic science such as mathematics, physics and chemistry, combined with the technical experience accumulated in production practice. Typical disciplines include civil construction, highway and bridge, machinery, water conservancy, electrician, automobile, electronics and information, thermal energy and nuclear energy, materials, instrumentation, environmental engineering, chemical industry and pharmacy, aerospace and so on. The goal of engineering training is to train senior professionals engaged in design, manufacturing, technology development and management in related production and technology fields.

4. Mathematics is a subject that studies concepts such as quantity, structure, change and spatial model. By using abstract and logical reasoning, the shape and motion of objects are counted, calculated, measured and observed. Mathematicians have extended these concepts in order to express new conjectures with formulas and establish strictly deduced truths from properly selected axioms and definitions. Because of the characteristics of the subject, science requires Excellence, and mathematics is more needed than engineering.
