Analysis of the Teaching of Ancient Chinese History in the Heritage Conservation Technology Major

Ancient Chinese history is an important part of the curriculum of the Heritage Conservation Technology major.Students can better understand the history of cultural relics and improve their humanistic literacy,which will help them in restoring cultural relics.At present,there are numerous challenges in teaching ancient Chinese history in the Heritage Conservation Technology major.These challenges necessitate the development of effective teaching reform strategies.This paper outlines these challenges and explores effective teaching reform strategies to provide a reference for educators.

Conservation of Jiaohe ancient earthen site in China

Earthen sites, which are mainly made of earth, are cultural heritages with historical, artistic and scientific values. Many extremely valuable earthen sites have been preserved in the arid areas in China. The earthen site of Jiaohe Ancient City is one of the earliest National Protected Important Cultural Heritage Sites. The Jiaohe Ancient City site exhibits all kinds of deteriorations, which can be found in the earthen sites in arid environments in China. Through a case study of the Jiaohe ancient earthen site, we present in this paper the comprehensive conservation technologies, including the mud bricklaying and reparation, wooden rod anchorage, crack grouting, surface potassium silicate （PS） penetration consolidation, and suspended steel beam ceiling, etc. Results of this case study showed that better conservation effects could be achieved by selecting proper PS penetration and crack grouting processes based on the deterioration characteristics of the earthen sites. The technology of mud bricklaying and reparation was also an effective method for preventing the earthen body from collapsing. Compared with traditional conservation technologies, the suspended steel beam ceiling technology could effectively reduce the negative impacts to the original state of the earthen site. As for unstable cliffs, a new method using composite anchor rod of bamboo and steel with massive loose earth was applied. Deformation monitoring and temporary supports were critical and indispensable measures for the safe of site conservation projects. Through years of monitoring and practical operation at the Jiaohe ancient earthen site, deterioration at the site has been effectively controlled.

Energy and Water Conservation Technology Analysis of Water Supply and Drainage of the Building

At present,China’s social and economic development is faster and faster.At the same time,people pay more and more attention to the construction concept of energy and water conservation.We can see the popularization and development of the concept of energy saving and water saving in every major field of our country,the same is true in the construction field.In order to effectively protect the ecological environment and maximize the use of limited resources,the energysaving and water-saving technology of the building,as well as water supply and drainage technology should be actively used.Based on this,this paper first analyzes the application significance of water supplydrainage and energy-water conservation technology in the construction field,analyzes the current situation of water supply and drainage in China,and proposes the application of water supply-drainage and energy-water conservation technology of the building for reference.

Application of coal-water slurry on the rotary calcining kiln of pedgion magnesium reduction process

Energy saving has been an important concept in modern industry especially to the countries and regions with energy shortage such as China and Japan. Utilization of Coal-Water Slurry （CWS） can improve the burning efficiency of coal and reduce the pollutions of soot, sulfide and the nitride by burning lump coal directly. The CWS is a promising energy saving technique and the effectual substitute of oil. The study on the preparation and application of the CWS has made progresses in many aspects. The present paper studied the basal problems for applying the CWS on the rotary kilns during the calcining-dolomite process in the magnesium factory, summarized the key points for the application process of the CWS and gave the corresponding solutions.

Soil and Water Conservation Technology in the Zhifanggou Watershed

Soil and water conservation technology plays an important role in soil and water loss control and the construction of the ecological civilization in vulnerable areas. Here, soil and water conservation technology use over 70 years for the Zhifanggou watershed is summarized and ecological, economic and social backgrounds are determined through consultation with experts and reference to published literature. We found that soil and water conservation technology use includes soil and water conservation engineering technology, soil and water conservation cultivation technology and soil and water conservation biotechnology. Soil and water conservation technology utilization varied with people＇s demands and core problems at different developmental stages of the agricultural eco-economic system. The coupling process of the agricultural eco-economic system at Zhifanggou went through three stages. In stages I and II, soil and water conservation cultivation technology was applied to meet farmers＇ basic life demands. In stage III, all three technologies were applied comprehensively to solve eco-environmental problems and adjust industrial structure. To facilitate regional ecological civilization construction and sustainable development of the ecological economy and society, more emphasis should be given to research and development, implementation of soil and water conservation technology, stand structure improvement, forest grass quality enhancement, biodiversity, ecosystem functional improvement, development of soil and water conservation ecological resources, the coupling of soil and water conservation, and agricultural industry-resource optimization.
