Universities are the highlands of technological innovation. The "comprehensive improvement technology of sandy land" developed by Lei Ziqiang Research Group of Northwest Normal University can transform unused sandy land into cultivated land within 1 to 2 years; The Key Laboratory of Gene Editing and Breeding in Gansu Province of Lanzhou University is expected to break through the "choke point" technology of biotechnology breeding... In recent years, colleges and universities in Gansu Province have made a number of scientific and technological achievements closely linked with local development relying on national policies and local realities, made outstanding contributions to ecological protection and economic development, and also made positive exploration to ensure national food security. To control the desert and turn the sand nest into a golden nest, it is located in the closed area of Tianshuibao National Sandy Land, Huan County, Qingyang City, Gansu Province. The once desolate and dead sandstorm area is now green and green. The number of plant species has increased by 31 compared to 2020, and the vegetation coverage has increased from 0 to an average of 35%, with a maximum coverage of 60%. Huanxian County is located on the southern edge of the Mu Us Sandy Land and is one of the 379 key sand areas and counties in China. The huge change is due to the "loess plateau gully prevention and control combined soil barrier technology" developed by Lei Ziqiang Research Group of Northwest Normal University. "Using soil as the basic raw material, engineering biological combination measures can be taken to control the sand hazard and reduce water and soil loss in a short time by means of dredging, diversion, slowing down, blocking, fixing, promoting infiltration, water collection and soil fixation." Lei Ziqiang, professor of the School of Chemistry and Chemical Engineering of Northwest Normal University and director of the Key Laboratory of Ecological Functional Polymer Materials of the Ministry of Education, explained. At present, the promotion and application area of this technology in Huanxian County reaches 309000 acres. The Lei Ziqiang research group has also developed the "Comprehensive Improvement Technology for Sandy Land", which increases the water and fertilizer holding capacity of sandy land by 30%, reduces evaporation rate by 15%, and quickly improves the microenvironment and fertility of sandy land. Unused sandy land can be converted into arable land within 1 to 2 years. Based on this technology, 13000 mu sandy land Haloxylon ammodendron grafted Cistanche deserticola in Linze County of Zhangye City and Suzhou District of Jiuquan, with an output value of 3000 yuan per mu; For more than 30 years, the Key Laboratory of Ecological Functional Polymer Materials of the Ministry of Education of Northwest Normal University has had two generations and more than 70 teachers and students engaged in the research of ecological functional polymer materials. They provided research results to nearly 60 relevant units and enterprises free of charge to help local people realize their dreams of turning deserts into oases and sand nests into golden nests. Independent innovation and service for local economic development entered the State Key Laboratory for Advanced Processing and Reuse of Nonferrous Metals jointly built by Lanzhou University of Technology province and ministry, and teachers and students are doing experiments in an orderly manner. Electric heating alloy wire material refers to the metal alloy wire material used to make electric heating devices, which is widely used in various electric heating devices such as air conditioners, ovens, Electric blanket, etc. "Fast life is an important indicator to measure the quality of electric heating alloy obtained in the laboratory. In the past, the fast life of electric heating alloy wires in our country has a big gap compared with the most advanced level abroad." Shi Yi, standing deputy director of the State Key Laboratory for Advanced Processing and Reuse of Nonferrous Metals jointly built by the province and ministry, and professor of the School of Materials Science and Engineering of Lanzhou University of Technology, said. After in-depth research, the research team discovered the failure mechanism of electric heating alloys, namely
