Second, the origin, current level and social recognition of the two universities are completely different.

1, xi University of Technology, a provincial college in Shaanxi Province, formerly known as Xi 'an No.2 Industrial School, has distinctive military characteristics. He once belonged to the Ministry of Ordnance Industry, the State Machinery Industry Committee, the Ministry of Machinery and Electronics Industry and China Ordnance Industry Corporation.

There are provincial key disciplines: optical engineering, material processing engineering, mechanical manufacturing and its automation.

Major with national characteristics: measurement and control technology and instruments, mechanical design and manufacture and automation, metal material engineering, automation, software engineering, human resource management.

2. Northwestern Polytechnical University, also located in Xi 'an, is a 985,211engineering university, which belongs to the Ministry of Industry and Information Technology (formerly known as the Commission of Science, Technology and Industry for National Defense). The Ministry of Industry and Information Technology is directly under the Seventh National Congress, which is one of the seven sons of national defense. In the domestic military field, it is second only to Harbin Institute of Technology, and its comprehensive strength is second only to Xi Jiaotong University in the whole northwest. It has always been famous for its three airlines. The so-called three navigation means aviation, navigation and aerospace. These three colleges are also the pillars of the school.

There are national key disciplines: materials science and engineering, aerospace science and technology.

There are national second-class key disciplines: material physics and chemistry, material science, material processing engineering, aircraft design, aerospace propulsion theory and engineering, aerospace aircraft manufacturing engineering, man-machine and environmental engineering, aero-engine, electromechanical integration engineering, solid mechanics, circuits and systems, control theory and control engineering, computer application technology, weapon system and application engineering, and underwater acoustic engineering.

3. Talk about undergraduate enrollment.

Xi Polytechnic University enrolls 2 students in most provinces, and only enrolls 1 person in some provinces such as Shaanxi Province. And Northwestern Polytechnical University, no matter in which province, is an enrollment. The scores of natural strokes are also much higher than the former.
