we went to mianyang in northern sichuan to experience the technological atmosphere there. mianyang, which also started with the third front construction, is now the only science and technology city in china approved by the cpc central committee and the state council. in 2023, in the national innovation map, mianyang ranked 17th among the top 50 cities in terms of technological innovation competitiveness, rising 24 places in two years. it is one of the fastest-growing cities in the country and was named one of the top ten cities with the greatest potential for technological innovation in the country.

cctv reporter wang zizhuo: this is the production line of changhong tv in mianyang.an lcd tv goes offline every 6 secondsthis place has also witnessed the rapid development of mianyang's electronic display industry over the past 60 years.

cctv reporter wang zizhuo: walking into the trumpet-shaped vacuum tube, you will see the electron gun, deflection coil, and fluorescent screen. due to the electromagnetic field, the electrical signal hits the fluorescent powder and turns into a light signal. this is the "old tv" we have watched for decades.

fang lianhui, senior manager of the product research and development center of changhong smart display company: lcd tvs display images by controlling the arrangement and combination of liquid crystal molecules and the size of the voltage.

nowadays, lcd flat-panel tvs have been successfully reduced in size. from the light-emitting layer to the liquid crystal layer, the panel, which has more than ten layers, is only one centimeter thick.

fang lianhui, senior manager of the product research and development center of changhong smart display company: now, through the 10-bit lcd panel packaging process, the screen resolution has reached 7680×4320.

just now, the "fucheng no. 1" low-orbit satellite flew over mianyang and sent back real-time information about the situation on the ground. every day, this satellite flies around the earth 15 times to monitor the situation on the surface in real time.

du zhigui, general manager of mianyang tianyi space co., ltd.: more than 500 kilometers from the ground,microwave remote sensing imaging technology can penetrate clouds and detect millimeter-level subsidence on the ground.provide information for emergency relief, pre-disaster warning, etc.

zhu zhicheng, deputy general manager of sichuan jiuyiyuan particle technology co., ltd.: this is a medical cyclotron accelerator. the main purpose of this device is to accelerate charged particles to bombard different target materials and produce a variety of radioactive isotopes.

in 2021, jiuyiyuan's first medical cyclotron in the field of nuclear medicine has made breakthroughs in key core technologies and successfully achieved import substitution.

zhu zhicheng, deputy general manager of sichuan jiuyiyuan particle technology co., ltd.: it is mainly used in clinical diagnosis and treatment of tumors and other major diseases.

mianyang has also shown great potential and vitality in the development of the drone industry. this "double-body fixed-wing drone" uses the latest flight control law technology.it has excellent performance in application scenarios such as maritime monitoring and electronic pod flying.

zhu baojun, deputy general manager of sichuan yaolei technology co., ltd.: our drone has high structural rigidity and strength, and can fly normally in wind speeds of level 10.

today, mianyang has gatheredmore than 30 upstream and downstream companies in r&d, manufacturing, operation services, and airspace resources have formed a strategic emerging industry cluster for the development of the entire drone industry chain.

this is the "robot dog" in the fire emergency robot series developed by mianyang 58 institute.its autonomous obstacle avoidance, flexible movement, and superior ability to climb hills and slopes enable it to operate with ease in special environments such as toxic and harmful gas detection, search for dangerous and explosive items, and extraction of physical evidence in areas prone to collapse, thus ensuring the personal safety of investigators.

this humanoid robot is moving towardsthe functional development of human beings such as "strong limbs", "dexterous hands" and "smart brain".

in the future, robots of all shapes and sizes will move from science fiction to the real world.

technological innovation is everywhere. interconnection and integrated development. in recent years, mianyang has been gathering strong forces to build a pioneering zone for scientific and technological innovation with chinese characteristics.
