With the theme of “To Advance a New Journey to the Future through Science Popularization”, the event was held in a combination of online and offline approaches. It included exhibitions covering the science and technology led by party building, marine science and technology, aviation science and technology, ecological science and technology, research, development and protection of seed industry, and southern propagation breeding, while there were also other special science popularization sections like life and health, emergency, rural revitalization, epidemic prevention and control, carbon peaking and carbon neutrality, and food safety. In the main venue, interactive experience of marine science and technology, hands-on experience of scaling marine robot and interactive experience of aerospace could be seen. In addition, there were rocket models, Beidou navigation network models, drones, airplane models, etc., which was equipped with commentators interacting with the audience. Rubber-tapping-technology champion Hainong Yu and “Deep Sea NO.1” and others also appeared in the exhibition, allowing the public to closely feel the changes in production and life brought about by science and technology!

在海洋科技主题展区中，海南大学海洋科技展以“向海而生——智慧海洋 智慧生活”为主题，展出了海洋生物标本、海洋应用科技以及文创优秀作品、海洋牧场沙盘模型、光电一体化燃料电池概念小车、半自动化纳米催化剂合成设备、氢燃料电池2-20 kW电堆及系统、便携式水质检测仪、FORBID病原微生物快速分析仪等多件展品。其中的半自动化纳米催化剂合成设备，主要包括气流控制系统、温控系统、注射系统和微型反应器系统等，形成从仪器原理验证到关键技术研发、系统集成，再到应用示范和产业化的仪器设备开发链条。该系统制备的催化剂具有产率高、形貌规整、均一性好、结晶性高等特点，具有较好的市场应用前景。便携式水质分析仪具有光学稳定性强、检测准确性高且速度快、支持在520nm波长检测、超长使用寿命等显著特点；FORBID病原微生物快速分析仪采用创新的FORBID微生物检测技术，能实现微生物全自动检测，可做到无需对样品进行预培养，即可同时检测16个样品；各种海洋“硬科技”展现出海大的科研“硬实力”。

In the marine science and technology exhibition area, Hainan University, with the theme of “Sea and New Birth—Wisdom of Sea, Wisdom of Life”, exhibited marine biological specimens, marine application products of science and technology, outstanding cultural and creative products, marine ranching sand table models, portable water quality detectors, photoelectric integrated fuel cell conceptual model cart, semi-automatic nanocatalyst synthesis equipment, hydrogen fuel cell 2-20 kW power stack and system, portable water quality detector, FORBID fluorescent photoelectric microbial diagnostic instrument, etc. Among them is the semi-automatic nanocatalyst synthesis equipment, which mainly included airflow control system, temperature control system, injection system and micro reactor system, etc. It formed a chain of instrumentation development of instrumentation principle verification, key technology development, system integration, and application demonstration and industrialization. The catalysts prepared by this system were characterized by high yield, regular shape, good homogeneity and high crystallinity, and had a good market application prospect. The portable water quality analyzer was characterized by strong optical stability, high detection accuracy and speed, availability for 520nm wavelength detection, and ultra-long service life. The FORBID fluorescent photoelectric microbial diagnostic instrument using innovative FORBID microorganism detection technology could achieve fully automatic detection of 16 samples at the same time without preculturing samples. In short, many technological products exhibited showed the scientific strength of Hainan University.

此外，南海因其多样的生态系统（如红树林、海草床、珊瑚礁等），孕育了全球海洋生物种类的1/3，其中包括鱼类3400余种，约占全球鱼种的10%。海南，位于南海之滨，是我国海洋面积最大的省份，拥有丰富的渔业资源。”海南大学南海海洋资源利用国家重点实验室南海海洋生物资源利用方向展示了蓝臀鹦嘴鱼、带纹条鳎、腹纹叉鼻鲀、蓝猪齿鱼等二十多件深海鱼标本供人观赏，其中蓝臀鹦嘴鱼身着蓝绿色外衣，鳞片外缘又为橙色，形成独特搭配，带纹条鳎身着多条黑褐色横带，造型十分吸睛。不少人驻足观看，近距离感受神秘深海的独特魅力。

In addition, the South China Sea, with its diverse ecosystems (such as mangroves, seagrass beds, coral reefs.), is home to 1/3 of the world’s marine species, including more than 3,400 species of fish, accounting for about 10% of the world’s fish species. Hainan, located on the shore of the South China Sea, is the province with the largest marine area in China and has rich fishery resources. More than 20 specimens of deep-sea fish such as chameleon parrotfish, zebrias zebrinus, arothron hispidus linnaeus and blue tuskfish were displayed, among which the chameleon parrotfish and zebrias zebrinus attracted a lot of visitors due to their unique appearances.

展区中央由白色桌布搭放的展台上，展示着由陶瓷制作的珊瑚礁、海草、海螺等“海洋物种仿生艺术创作”和手工纸制作的“南海印象”等文创产品以及由螃蟹、虾等制作的标本，富有创造力和想象力，受到了不少小朋友的喜爱。除此以外，在南海现代化海洋牧场沙盘一区，码头、观测站、钻井平台、探测船、风力发电风车等按比例分布其中，辅以炫酷的灯光，让人们直观地了解海洋牧场的运作机制的同时也留下了深刻的印象。此沙盘向人们诠释了海洋牧场的定义，即通过人工鱼礁、增值放流、生态养殖等措施增值养护渔业资源、改善海域生态环境，实现渔业资源可持续利用。

On the booth in the center of the exhibition area, there were bionic art handicrafts of coral reefs, seaweeds and conchs which were made of ceramics, creative products showing the culture of Hainan, as well as specimens made of crabs and shrimps, attracting a lot of children. In addition, in the modernized marine ranching sand table area, the wharfs, observatories, drilling platforms, detection vessels and wind power windmills were scaled down at the same proportion, supplemented by cool lights, so that people intuitively understood the operation of the marine ranching mechanism. This sand table explained to people the definition of marine ranching, that was, through artificial reefs, multiplication from more release, ecological aquaculture and other measures to conserve fisheries resources, improve the ecological environment of the sea, and to achieve sustainable use of fisheries resources.
