Undergraduate scale
We will divide the total undergraduate students of the College of Materials and Materials into 500 or less students, 500-1000 people, 1000-1500 people, 1500-2000 people, 2000-2500 people, and more than 3,000 people. The specific distribution ratio is as follows:
Obviously, the total number of undergraduate students is between 1000 and 1500, followed by the 500-1000, and the two universities account for 62%. In other words, more than half of the materials colleges are between 300 and 500 people.
　　 Graduate scale
We have a similar breakdown of the total number of undergraduate students (masters + doctors) with undergraduates, the specific proportions are as follows:
It can be seen that the total number of graduate students in the school is the largest under 500, followed by 500-1000. Obviously, most college graduate students do not have more than 1,000 students, and they are concentrated below 500.
Top ten undergraduate and graduate students
According to statistics, the top ten colleges with the largest number of undergraduate and graduate students (Masters + PhDs) are shown in the following table:
  Ranking | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
Undergraduate | Wuhan University of Technology | Northeastern University | Lanzhou University of Technology | Wuhan University of Science and Technology | Taiyuan University of Science and Technology | Hefei University of Technology | Chongqing University | Nanjing University of Technology | Harbin University of Science and Technology | Tianjin University of Technology |
Postgraduate | Northeastern University | Beijing University of Science and Technology | Wuhan University of Technology | South China University of Technology | Northwestern Polytechnical University | University of Science and Technology of China | Chongqing University | Shanghai University | Harbin Institute of Technology | Shanghai Jiaotong University |
If compared with the 2012 Ministry of Education's subject evaluation rankings, the top ten colleges with the largest number of undergraduates, except Wuhan Science and Technology ranked in the top ten, the rest are in the top ten. The top ten colleges with the most graduate students are mostly ranked in the top, and six of them are in the top ten.
Comparing the above table with the ranking of the Ministry of Education's subject evaluation in 2012, we can see that the total number of undergraduate students in the school has little to do with the ranking of the subject evaluation; while the total number of graduate students in the school indicates to some extent the academic strength of the institution in its graduate students. The number of students enrolled is reflected. The number of graduate students enrolled in universities with higher academic rankings is relatively large.
　　 Ratio of undergraduate and graduate students
Finally, Xiao Bian also ranked the number of undergraduate students (masters + doctors) and undergraduates in the top 60 institutions. The top 15 universities with the largest number of graduate students and undergraduates are as follows:
Ratio ranking     | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 |
ratio | 1.60 | 1.50 | 1.46 | 1.38 | 1.38 | 1.13 | 1.12 | 1.10 | 0.97 | 0.95 | 0.92 | 0.91 | 0.84 | 0.79 | 0.72 |
Institution | Beijing University of Chemical Technology | Zhejiang University | Shanghai Jiaotong University | Tsinghua University | Northwestern Polytechnical University | University of Science and Technology of China | Beijing industry university | Beijing Aerospace University | Beijing University of Science and Technology | Xi'an Jiaotong University | South China University of Technology | Harbin Institute of Technology | Shanghai University | Northeastern University | Beijing Institute of Technology |

Super-low Ash Coal Activated Carbon
coal-based activated carbon for water purification is widely used in the deep purification of drinking water, industrial water and wastewater. Industrial water purification and gas phase adsorption, such as power plant, petrochemical, oil refinery, food and beverage, sugar wine, medicine, electronics, fish, marine and other industries water purification treatment, can effectively absorb the water in the free, sulfur and other organic pollution special The price of the coal-activated carbon filter material, especially the precursor of the Mutant (THM), is to purify the impurity and remove the odor. can also be used for industrial exhaust purification, gas desulfurization, petroleum catalytic reforming, gas separation, pressure swing adsorption, air drying, food preservation, gas masks, media carrier recovery solvent Coal activated carbon, industrial solvent filtration, decolorization, purification and so on.
Use: Used in the purification of drinking water, deodorizing, brewing industry, decoloring of pharmaceutical and chemical products.
