在工程教育专业认证及本科国家教学质量标准视角下,针对国内大多数化工类高校传递过程原理教学中存在的弊端,通过对比国内外化工类高校传递过程原理的开设情况,并在大多数国内化工类高校“化工原理”与“传递过程原理”同时开设的基础上,提出优化传递过程原理课程知识体系,将“三传”发展史融入课程教学,提高学生主动学习兴趣,以类比教学为主、多种教学方法耦合教学,突出学生中心和产出导向的课程考核标准等教学改革措施。改革后的传递过程原理课程不仅提高了学生的自主学习兴趣,还提高了学生解决复杂化学工程问题的能力,取得了良好的教学效果。 相似文献

工厂设计与化工制图课是我校高分子材料与工程专业限选课,开课时间为第六学期,是在修完专业基础课程之后所开的一门综合性较强的理论实践课。本门课程的掌握程度直接关系到第八学期毕业设计质量的好坏。针对工厂设计与化工制图课程教学中存在没有足够的时间思考、完成的设计和绘图出现雷同、设计说明书和图等的抄袭现象,对该课的教学内容、教学方法、考核方式等方面进行改革探索与实践。改革结果提高了学生的学习质量,促进教师的教学水平提高。 相似文献

作为化工专业的基础课,《化工原理》课程的教学中包含着一个重要的组成部分———课程设计。作为实践教学环节,课程设计的目的是让学生在教学过程中,对所学过的课堂知识有一个感性认识。如完成精馏塔的设计,就会使学生在设计过程中直观地了解工艺条件的选择和控制对塔... 相似文献

以提高学生的工程应用能力为目标,跨学科创新性地将软件工程里 “敏捷开发”方法中的Scrum模式引入化工原理双语教学中,提出了将Scrum模式嵌入双语教学的改革思路。在此基础上,初步形成了以工程项目为中心、以学生为主体的敏捷双语教学模式,并以实例探讨了此新型教学方法的开展与实施。本文就化工原理双语课程的教学理念、教学方法和考核手段进行了一系列相关的改革和创新,此方法可作为传统教学方式的一种有效补充。本研究为“新工科”背景下化工原理双语课程的教学改革提供了一种全新的思路和理念。 相似文献

化工过程分析与合成是化工类实践性非常强的专业课程,其主要手段是过程系统模拟。如何将化工过程分析与合成理论和模拟软件Aspen使用进行有机结合是此课程教学过程中需解决的重要问题。将化工过程分析与合成中的序贯模块法理论与相关的Aspen模拟进行有机融合教学,重点解决由于断裂流股选取不合适及初值设置不合理使模拟结果不收敛的问题。以此可使化工过程分析与合成理论教学更加生动,学生更易掌握,同时可提高学生对Aspen软件使用和解决实际问题的能力,为后续的工程设计打下坚实的基础。 相似文献

The chemical reactivity concepts of density functional theory are studied through a unified view in the temperature-dependent approach provided by the grand canonical ensemble. This procedure leads to a more general perspective that enriches our understanding of the behavior of the average energy and its derivatives with respect to the average number of electrons, provides alternative definitions for those quantities that are “ill defined” at zero temperature, and allows one to determine the relationships among reactivity concepts at any temperature. In particular, it has been found that at high temperatures the parabolic model for reactivity indicators may be justified through the electronic entropy term in the Helmholtz free energy, and that at nonzero temperatures there is an electronic heat capacity contribution to the average energy. In summary, the unified view of the temperature-dependent approach is an important complement to the zero-temperature formulation that clarifies fundamental issues therein. 相似文献

In Lithuania research and development in chemical analysis are concentrated in scientific institutes and universities. The main fields of interest focus on biosensors, electrochemical sensors, sampling techniques and methods, study of atomization processes in spectrochemical analysis and noise evaluation in analytical measurements. Some laboratories also take part in international environmental monitoring programmes. There are about 50 researchers at the Ph.D. level engaged in analytical chemistry and several hundred technicians specialized in the field of analytical control. About one hundred chemical laboratories are active in scientific institutes, universities and factories. Specialized laboratories of chemical analysis are at the disposal of Environmental Control and Health Protection Departments and forensic investigation organizations. So far no laboratories are accredited according to the ISO 9000 norms. Special courses on analytical chemistry are offered at a few schools of higher education in the country. Only at the Department of Analytical Chemistry of the University of Vilnius specialized programmes are available to postgraduate students working towards a Ph.D. to improve their skills in current techniques of analytical chemistry. Recently the Technical Committee TC-16 for Chemical Analysis was formed within the standardization system of Lithuania. Its main activities are centered on issues such as national terminology, certified reference materials (CRMs), analytical methods and analytical quality assurance. There are numerous problems related to national terminology, the preparation of special documents in the field of analytical control and the production of regional environmental CRMs. Problems, also arise in obtaining and using CRMs for analytical instrument calibration and validation. 相似文献
