摘要：随着数智时代的到来,传统的教育模式和方法已难以满足未来人才培养的需求。将数智化的元素融入课程思政建设中,不仅可以提高教学的效率和效果,还可以培养学生的数智思维、创新能力和跨学科综合能力,以适应数智环境下对人才的需求。以化材类专业基础课程《机械设计基础》为例,通过分析当前专业基础课课程思政数智化育人面临的难题,结合课程内容探索数智化背景下化材类专业基础课课程思政育人模式,为推动专业基础课课程思政数智化育人提供参考。With the digital era arriving, traditional educational models and approaches have become incapable of fulfilling the requirements for future talent cultivation. In order to meet the demands for talents in the digital and intelligent milieu, it is quite significant to integrate the digital and intelligent elements into the construction of ideological and political education within courses. It can not only enhance the efficiency and effectiveness of teaching but also foster students’ digital and intelligent thinking, innovation capabilities and interdisciplinary comprehensive competences. In this paper, taking the basic course of chemical engineering “Mechanical Design Foundation” as an example, the study is conducted to analyze the difficulties faced by the ideological and political education of professional basic courses in the digital era, and explore the ideological and political education model of professional basic courses in the chemical materials field under the digital background. It could provide reference for promoting the ideological and political education of professional basic courses in the digital era.

摘要：以普通425水泥为主要胶凝材料、双氧水为发泡剂,乳液为稳泡剂,制备掺杂钼尾矿发泡水泥.以乳液、水温、纤维、双氧水等作为影响因素设计正交试验,以抗折强度、干密度和吸水率为评价指标,对发泡水泥制备工艺进行优化,并对最优工艺做了验证性实验,采用X射线衍射仪和红外光谱仪对发泡水泥水化产物的物相及分子结构进行了表征.结果表明,掺杂钼尾矿发泡水泥的最优制备工艺为水温38℃、纤维4.0g、乳液30g、双氧水37g,影响因素主次顺序依次为:温度、双氧水、乳液、纤维.结构表征结果表明,发泡水泥制品中含有大量的SiO_2,还含有钙矾石、Ca(OH)_2和少量非晶态的CaCO_3等水泥水化产物的形成.
