1引言如何去除铁水中的磷是炼钢工必须面临的最大挑战，特别在某些钢厂内，由于原材料化学成份所导致的铁水磷含量较高条件下，这种情况更为严峻。在任何一个给定的磷含量条件下，钢水和炉渣中的磷分配取决于炉渣中P2O5的活度，其值是化学成分和温度的函数。碱性氧化物的存在（例如CaO）和低温条件可导致P2O5活度系数的降低，因而可将磷分配比提高一个数量级。

Cervical cancer is a severe threat to women's health. The majority of cervical cancer cases occur in developing countries. The WHO has proposed screening 70% of women with high-performance tests between 35 and 45 years of age by 2030 to accelerate the elimination of cervical cancer. Due to an inadequate health infrastructure and organized screening strategy, most low-and middleincome countries are still far from achieving this goal. As part of the efforts to increase performance of cervical cancer screening, it is necessary to investigate the most accurate, efficient, and effective methods and strategies. Artificial intelligence(AI) is rapidly expanding its application in cancer screening and diagnosis and deep learning algorithms have offered human-like interpretation capabilities on various medical images. AI will soon have a more significant role in improving the implementation of cervical cancer screening, management, and follow-up. This review aims to report the state of AI with respect to cervical cancer screening. We discuss the primary AI applications and development of AI technology for image recognition applied to detection of abnormal cytology and cervical neoplastic diseases, as well as the challenges that we anticipate in the future.
