    Based on the curriculum concept of the new engineering, this paper studies the current situation and problems of the curriculum from the perspectives of curriculum, universities, teachers andstudents, puts forward some suggestions for curriculum reform and carries out practical exploration. Infinds out that the current curriculum concept is outdated, the curriculum content and system emphasizethe academic and knowledge system , and the isolation from engineering practice is strong , and the curriculum evaluation system is relatively simple. Curriculum reform should emphasize the innovation of curriculum idea, the reconstruction of knowledge system and the multi-dimensional curriculum evaluationmode. In universities , there is a shortage of Higher Mathematics teachers. Teachers' teaching tasks areheavy, and the teaching facilities are outdated. Curriculum reform should strengthen the introduction ofpublic course teachers and teacher training, pay attention to the upgrading of teaching facilities.Someteachers'teaching mode is relatively simple and teaching interaction is less. Curriculum reform shouldadvocate teachers to adopt modern teaching and interaction mode, and introduce engineering cases in thecontent. Students'interest in learning is low, and the phenomenon of playing with mobile phones inclass is relatively common. Teaching reform should guide students to participate in, make the curriculum more suitable for students'needs, so that teaching implementation can stimulate students' interest.

    At present, disciplinary inspection and supervision organs at all levels, especially the disci-plinary commissions of colleges and universities, usually use paper accounts or electronic forms to man-age problem clues in the process of handling them. All types of document filling are manually filled out.which makes the document archives unable to be related to the problem clues in an active manner, resul-ting in low management quality and efficiency , which is not conducive to the dynamic tracking and man-agement of the entire process and measures of problem clue handling. This study proposes to utilize thepowerful functions of the WPF framework and adopt the MVVM pattern to design and develop an information dynamic management and traceability system , which can dynamically manage documents and problem clues, monitor and judge the process of problem clue disposal, and further improve the eficiency ofdisciplinaryinspection and supervision organs’ problem clue disposal management.

    In order to investigate the effects of adding different proportions of ammonium chloride and am-monium nitrate on the solubility, metastable zone and crystallization of ammonium sulfate, the solubilityand metastable zone of the mixed solution were measured by laser method. The solution was cooled andcrystallized. The thermodynamics of mixed solution is calculated by using Van't Hoff equation. Themixed solution was cooled and crystallized. The average particle size and distribution of the crystals wereinvestigated by sieving method, and the crystal morphology was analyzed by macro. The results showthat NH4+can reverse the hydrolysis of ammonium sulfate, resulting in a significant decrease in solubilityof the mixed solution compared with that in pure water; Cl and NO, also affect the solubility of ammo-nium sulfate, and Cl- has a more obvious effect. When the ratio of ammonium chloride to ammoniumnitrate was 1:2, the width of ammonium sulfate metastable zone became wider, indicating that ammoni-um nitrate could inhibit ammonium sulfate nucleation to a certain extent. When the ratio of ammonium chloride to ammonium nitrate was 2:1, the metastable zone width of ammonium sulfate was narrower thanthat of pure ammonium sulfate. No matter how the proportion of ammonium chloride and ammonium ni-trate was adjusted, the crystallization amount of ammonium sulfate increased. When the ratio of ammonium chloride to ammonium nitrate was 1:1, the crystallization capacity and average particle size were thelargest. The related research results can provide a new idea for optimizing the crystallization of ammonium sulphate mother liquor obtained by ozone denitrification and ammonia desulfurization.

    Urban landscape is not only a typical characteristic of urban expansion , but also an importantindicator to evaluate the level of urbanization. Measuring landscape characteristic and analyzing its spa-tio-temporal evolution pattem is helpful to reveal the trend of urban expansion and provide a support forrational urban planning. Taking Chenggong district of Kunming of Yunnan province of China as the casestudy, this issue measured the characteristics of urban landscape expansion with Multi-order AdjacencIndex ( MAl) and analyzed its geographic cluster pattern using spatial autocorrelation analysis methodfrom 2005 to 2020 (every 5 years is a calculation period, and there are three periods in total). Firstly.we measured the characteristic of urban landscape according to the MAl values, and then , based on theMAl value , the spatial autocorrelation analysis method was adopted to detect the geographic cluster patterns and the urbanization trend. The results showed that: l) Sprawl type and edge type were the maintypes of urban landscape expansion in the study area, while the other types were more average and haveobvious gap compared with the above two types; 2) In the early stage of urban development ( the first 10years) , the sprawl type dominated , and then the trend was obviously declining in the later stage; 3 )The high-high cluster areas of MAl showed the trend of urban expansion from the center to the surround-ing areas, and the pace of urbanization was developing towards the direction of “ compact". These re-sults indicated that the combination of MAl and spatial autocorrelation is an effective way to measure anddetect the characteristics of urban landscape expansion and its spatio-temporal evolution process.

    The mining depth of acertain polymetallic open-pit mine is large , and the slope is high andsteep. The stability of the mining slope is directly related to the normal operation of the mine, so the analysis and evaluation of its slope stability is crucial. Based on the geological conditions of mining engineering, mining status, and rock mass quality evaluation, a slope model is established for qualitativeand quantitative stability analysis using the technical means of on-site rock mass structure inyestigation+ qualitative analysis of stereographic projection + quantitative calculation of slope limit equilibrium meth-od”. The slope safety coefficients are calculated respectively under three working conditions: selfweight, self weight + blasting and self weight + earthquake. he results show that the current slope ofopen-pit mine is stable as a whole , and meets the requirements of the safety level, which illustrates thatthe slope structure parameters of the stope design have certain rationality. At the same time , it is suggested that smooth blasting and prespliting blasting should be adopted when the slope is close to the slopedesign boundary. lt is necessary to promptly clean up the peeling rocks caused by freeze-thaw action toensure mine production safety and reduce risks.
