Graduate three in environmental engineering is preparing to graduate. On the one hand, it depends on the situation of the research group, on the other hand, it depends on the individual. If you just want to graduate, sci papers will not be too difficult. If you want to send a good article, the above two points are indispensable, and you need the right time and the right place.

The second section of the paper is the paper published in the second section of sci journal. When we see the division of journals in the first and second areas, we should first react that this is a unique division method of sci journals, and other journals do not have this division. This classification of sci journals has the same meaning and purpose as other standards, which is convenient for the management and classification of journals and will make the selection of authors more efficient.

The division of sci journals is mainly based on the influencing factors of publications. No matter whether it is Chinese Academy of Sciences or jcr, the journals of the second division are all journals with high impact factors. The indicators of the two journals are second only to the first one, and their academic value is very high. In many fields in China, more and more sci papers are required to be published in second-class and above divisions, that is, only second-class and first-class divisions are recognized, so the status and role of second-class divisions' journals are obvious.
