In the ancient city of Xi'an, the campus of the Air Force Military Medical University was cold in early winter. In the morning, Luo Erping, a professor in the Department of Military Biomedical Engineering, walked past the sculpture of "upholding morality and cultivating talents, and improving medicine to win the battle" in a hurry as usual. Entering the low-pressure chamber laboratory, Luo Erping continued to carry out the reliability verification of a certain type of equipment, and the busy lights didn't go out until late at night. "To achieve the centenary goal of building the military as scheduled, we must accelerate the transformation of science and technology into combat effectiveness. As college researchers, we should not only have the courage to climb the peak of science and technology, but also put our feet in the front line troops to truly win the service guarantee." Luo Erping said sincerely during the discussion on the spirit of the 20th CPC National Congress organized by the university. After the 20th National Congress of the Communist Party of China, the Air Force Military Medical University organized teachers and students to carefully study the original report at the first time. Luo Erping has gained a deeper understanding and thinking about "strengthening the military through science and technology" and "accelerating the transformation of science and technology into combat effectiveness" in combination with his own teaching and research. Educate people for war and serve the country through scientific research. In this school, many researchers like Luo Erping have devoted themselves to the journey of building a strong military through science and technology for several years. Their footprints are all over the desert Gobi, the snow covered plateau, and the islands in southern Xinjiang. They have written a vivid practice of winning the war through fine medicine in the motherland. Reach out to touch the sky and guard the "heartbeat" of the plateau. The night is deep, and the cold wind is biting at an airport on the plateau. At the end of the flight, Luo Erping returned to the station with the students and carefully sorted out the tower oxygen supply guarantee data of the day. "Only those who have been here know the hardships of the plateau." More than 20 years ago, Luo Erping, who had been teaching for a short time, learned for the first time about the suffering of plateau soldiers from lack of oxygen in a training course through the introduction of a plateau military doctor. Soon, when he learned that the school would go to the plateau for inspection, he signed up. Luo Erping came to the Shenxian Bay Sentry, which is more than 5000 meters above sea level. Seeing the soldiers' lips cracked by the piercing cold wind, the "plateau red" on their faces for a long time, and hearing the story that they fell down due to lack of oxygen while patrolling in the snow, he felt like a needle in his heart. "No matter how difficult it is, we must send oxygen up!" After returning to school, Luo Erping decided to tackle the problem of plateau oxygen supply. At that time, this research field was almost blank in our army, and many colleagues advised Luo Erping to give up this "impossible task". But he remained unmoved. Luo Erping's persistence has infected his colleagues, and his team has gradually developed from a single person to a group of people. A few years later, Luo Erping felt particularly successful and excited about the successful development of a single soldier oxygen increasing respirator that is the size of a kettle and can work for 10 hours continuously. In the Yushu earthquake in 2010, all the troops marched into the plateau disaster area with the individual oxygen increasing respirator developed by Luo Erping. This is the first large-scale move of this type of equipment to the "battlefield". Luo Erping paid close attention to the first-line feedback with a worried mood. "The equipment has no battery, so it is troublesome to charge" "The air inhaled into the nose is too cold"... Luo Erping carefully recorded every suggestion from the officers and soldiers, and studied and improved one by one. "The significance of scientific research is to solve practical problems in building combat effectiveness." With the unremitting efforts of Luo Erping and the team, the "oxygen supply" of individual soldiers
