AND、OR、NOT	Boolean logic combinations of key words is a skill used to expand or refine search parameters. (1) AND (1) AND: Refines search parameters (2) OR (2) OR: Expands search parameters (3) NOT: Excludes irrelevant parameters

DOI stands for Digital Object Identifier （ D igital O bject I dentifier ） ,
and is the unique identifier for objects on the internet. It can be used to create persistent link and to cite articles.

Using DOI as a persistent link

To create a persistent link, add「http://dx.doi.org/」「 http://dx.doi.org/ 」 before a DOI.
For instance, if the DOI of an article is 10.5297/ser.1201.002 , you can link persistently to the article by entering the following link in your browser: http://dx.doi.org/ 10.5297/ser.1201.002 。
The DOI link will always direct you to the most updated article page no matter how the publisher changes the document's position, avoiding errors when engaging in important research.

Cite a document with DOI

When citing references, you should also cite the DOI if the article has one. If your citation guideline does not include DOIs, you may cite the DOI link.

DOIs allow accurate citations, improve academic contents connections, and allow users to gain better experience across different platforms. Currently, there are more than 70 million DOIs registered for academic contents. If you want to understand more about DOI, please visit airiti DOI Registration （ doi.airiti.com ）。

Parallel Abstract 〈TOP〉

Oxide Metallurgy is a method that could be used to effectively utilize the formation of inclusions to improve the steel quality by pinning grain boundary or forming IAF.  Previous studies shows that the deoxidization and desulphurization ability of Ce is higher than Al and Ti, the commercialized deoxidizer,. Therefore, Ce was chosen as the main deoxidizing agent in present research to form the inclusions that could be used to improve the steel quality and to reach the higher cleanliness of steel. In present study, we focus on predicting the inclusion types which could be applied to oxide metallurgy. Wagner’s interaction model (ai = fi * [% i ] ; log fi = ∑_i^j▒〖e_i^j*[ %i ]〗) was applied to build a calculation model to predict the formation of inclusions after the deoxidization and desulphurization process. A thermodynamic prediction module of Ce inclusions was constructed and shows a promising results which is proved by the experiment using Ce as the main deoxidizing agent. The sample was investigated after it was quenched from high temperature. There are three types of inclusion usually formed such as Ce2O2S, Ce2O3, CeAlO3. Furthermore, the size, shape morphology and profound characteristic of each type of inclusion were also studied.
