摘要：分析化学实验教学改革包括教学方式改革和实验内容设计方式改革.在教学方式的改革上,由传统的实验教师演示实验为主改革为由理论课教师和实验教师联合授课的教学模式,并加以讨论式和多媒体辅助的教学方法.在实验内容设计方式的改革上,由验证实验为主以提高学生实验操作能力为目标的实验内容,改革成贴近实际的设计实验,籍此调动学生学习的积极性和主动性,增强毕业生的创新素质,挖掘学生的潜能.同时,将节约和环保的理念引入到实验设计中,加强学生绿色化学的概念.

摘要：A series of WO3 samples with different crystalline phases were prepared by the thermal decomposition method from ammonium tungstate hydrate.X-ray diffraction（XRD）,scanning electron microscopy（SEM）,high-resolution transmission electron microscopy（HRTEM）,X-ray photoelectron spectroscopy,and N2 adsorption-desorption were used to characterize the crystalline phase,morphology,particle size,chemical composition,and surface area of the WO3 *** formation of hexagonal（h-WO3） and monoclinic（m-WO3） crystal structures of WO3 at different temperatures or different times was confirmed by XRD.m-WO3 is formed at 600 ℃,while m-WO3 starts to transform into h-WO3 at 800℃.However,h-WO3,which forms at 800℃,may transform into m-WO3 by increasing the calcination temperature to 1000℃.SEM results indicate that m-WO3 particles exhibit a bulky shape with heavy aggregates,while h-WO3 particles exhibit a rod-like ***,m-WO3 crystals are sporadically patched on the surface of the h-WO3 rod-like particles,resulting in the exposure of both m-WO3 and h-WO3 on the *** is observed that the monoclinic phase（m-WO3）/hexagonal phase（h-WO3） junction was fabricated by tuning the calcination temperature and calcination *** relative ratios between m-WO3 and h-WO3 in the phase junction can readily be tailored by control of the calcination *** photocatalytic activities of WO3 with different crystalline phases were evaluated by the photocatalytic degradation of rhodamine B as a model pollutant.A higher photocatalytic activity was observed in the WO3 sample with the m-WO3/h-WO3junction as compared with the sample with only *** improvement of photocatalytic activity can be attributed to the reduction of the electron-hole recombination rate owing to the formation of the phase junction,whose presence has been confirmed by HRTEM and photoluminescence spectra.

摘要：无机非金属专业实验教学改革有利于以综合应用素质为主的人才培养。对实验内容的设计,由传统的单一实验为主的实验项目改革成协同完成的综合专业和基础实验内容的实验项目。以协同实验和综合实验为主的实验训练,不仅提高学生实验操作能力,还培养学生相互合作,综合运用专业知识解决问题的能力,以此为目标来达到学生将知识迁移应用解决实际问题的能力。同时,增强专业实验室的文化宣传,潜移默化地培养学生的实验素质。

摘要：无机材料性能学是涉及到材料性能原理与影响因素的一门学科。多维教学法将本门课程的教学分为课堂、实践和应用教学三个方面。将支架式知识体系、脚手架式教学以及竞争与合作的课堂环境等教学方法和观点融入课堂教学中。综合设计性实验、学徒式创新训练和情境式工厂实践等实践环节对课堂教学加以补充,提高学生的实践创新能力。最后,应用教学是多维教学法中重要的一环,是课堂和实践教学的目的。
