- He had the correct idea of trying to explain chemical phenomena in terms of ultimate particles .
他有试图用最终的微粒解释化学现象的正确想法。 - The application of chemistry mcai in middle school can enable students to observe and analyse chemical experiments , explore microcosmic world , understand abstract principles as well as get to know some chemical phenomena and processes that are difficult to be observed in reality
多媒体cai在中学化学中的应用使学生更好地观察和分析化学实验，探析微观世界，理解抽象原理，认识难以实地观察的化学现象和过程等。 - Consequently concrete production practices are now being conducted by relying on more experiences or trial and error than related theory . so the study on the interfacial chemistry phenomena and rheological properties of the “ cement - water - superplasticizer ” system is in active demand . the systematical study on the interfacial properties and their influence factors based on the theory of colloidal science , interface chemistry , chemistry of cement and polymer science were conducted in order to establish the relationship among interfacial properties , microstructure and rheological characteristics of “ cement ? water - superplasticizer ” system , and provide the theoretical guide for the manufacture and applications of cement , concrete and superplasticizers
本文选择“水泥-水-高效减水剂”系统的界面化学现象和流变特征作为研究课题,旨在通过深入系统地研究水泥与高效减水剂在水介质中的一系列界面化学现象及其影响规律,利用胶体化学、界面化学、水泥化学和高分子化学的相关基础理论,分析水泥与高效减水剂的相互作用机理,确定系统中界面化学现象、系统微观结构和流变特性的关系,指导水泥、混凝土及外加剂的生产实践。 - Superplasticizer has undoubtedly played the key roles in the progress of high performance and the functionalization of concrete . but excessive research work has been made to develop new types of admixture and production technology , while the study on basic principles concerning the interaction of cement and superplasticizer , physico - chemical phenomena of interface were insufficient in the past , due to the fact that admixtures was regarded as a mysterious know - how or technical product
但长期以来,混凝土外加剂在水泥混凝土行业一直作为一种技术秘密或技术产品在使用,因此大量的研究工作都集中在外加剂的制备方法、生产技术和应用技术的研究上,而对水泥与外加剂相互作用的基本原理、界面化学现象和作用过程等基础研究却重视不够。 - In this paper , the microstructure changes of polypropylene induced by a complex combination of shearing , compression , stretching and friction actions during single pan - milling or co - milling with iron , uhmwpe and waste tire rubber chips ( wtr ) were studied and the stress induced effects were revealed . the structure and morphological development of iron particulates and wtr during pan - milling and co - milling with polypropylene were also characterized . the properties of pp / fe , pp / wtr and pp / wtr / fe composites prepared through pan - milling techniques were investigated
本文利用磨盘型力化学反应器对被碾磨材料施加强大的剪切、环向应力、挤压、拉伸和摩擦作用，研究聚丙烯碾磨和共碾磨粉碎过程微观形态结构和性能的变化，以及聚合物在碾磨过程中呈现的力化学现象，并将其应用拓展至金属、橡胶等体系，研究碾磨粉碎在聚丙烯铁超微粉体的制备、高交联密度弹性材料废旧轮胎橡胶( wtr )的超微粉碎，以及pp fe ， pp wtr材料的性能与碾磨作用的关系。
