A 50-kilogram hydrogen energy UAV jointly developed by the Aviation Industry Corporation of China and Tsinghua University recently completed a 30-hour long-endurance cross-day-and-night continuous flight. It has broken through the integrated flight, propulsion and control design technology based on the output characteristics of hydrogen fuel cells, broken the record of similar domestic aircraft, and its endurance capacity has reached the international leading level. During the takeoff process, the project innovatively adopted the autonomous release by an unmanned vehicle, forming an unmanned system of "unmanned vehicle + UAV", and successfully completed the demonstration and verification of the usage scenarios under non-standard runway conditions.
The team from Peking University has proposed the RainyGS technology. By combining physical simulation with a 3D Gaussian splash rendering framework, it has achieved high-quality simulation and presentation of dynamic rain effects in real scenes, ensuring physical authenticity. This technology can not only generate realistic raindrop trajectories, water surface fluctuations, and light refraction effects in real time, but also allow users to flexibly adjust the amount of rainfall. It provides pixel-level trustworthy dynamic twins for scenarios such as autonomous driving simulation and disaster deduction.
The Zhengrong big model of Feidu Technology, with its AI - driven all - element digitization capability, breaks through the bottleneck of traditional digital twin modeling by using technologies such as AI oblique photography reconstruction and neural network segmentation. It increases the modeling efficiency of urban scenes by 60%, with centimeter - level accuracy. It supports dynamic partial updates and multi - domain intelligent decision - making, achieving a leap from an "empty - shell model" to a "conversational living system". It has been applied in multiple fields such as smart cities, smart emergency response, smart water conservancy, and smart mines, promoting the intelligent upgrade of the industry.
Shenzhen Customs takes the lead nationwide in rolling out the "full-capability version" DeepSeek-R1 intelligent inspection robot. It can complete the safety inspection of the hazardous chemicals environment in 3 seconds, with an 80% increase in efficiency. The accuracy rate of commodity classification reaches 99.2%. It has achieved a 30% reduction in the overall inspection time of imported fruits at the port, a 50% reduction in the overall inspection time of imported hazardous chemicals, and an 80% reduction in the links requiring manual intervention. The customs clearance efficiency has been significantly improved, injecting new development vitality into promoting the development of the real economy and optimizing the business environment at the port.
The BYD Han L and Tang L series of models are officially launched. Both new cars are built on the BYD Super e - platform, which features a 1000V high - voltage charging system and megawatt flash - charging batteries. The new cars can accelerate from 0 to 100 km/h in 2 seconds, and their top speed exceeds 300 km/h.
The Han L and Tang L are important flagship models of the BYD brand aiming at the mid - to - high - end market. They will be equipped with the "God's Eye B" high - order intelligent driving laser version across the board, which can realize functions such as urban piloting, high - speed piloting, valet parking, and active safety. Along with the launch of Han L and Tang L models, BYD's first batch of 500 "megawatt flash-charging stations" were put into use simultaneously.
