December 24th,The first large-scale cruise ship made in China
The "Aida Modu" departed in Shanghai.
The first trial operation was carried out.
It will officially start its first commercial voyage on January 1, 2024.
Large cruise ships are extremely difficult to design and build.
It can reflect a country's ability to build equipment.
with the level of comprehensive science and technology.
Deliveries of the Aida Mordu".
It marks our country becoming the fifth in the world
Countries that can build large cruise ships
There is still a week left until the end of 2023.
This year we also witnessed:
Which country's important weapons have come out and made breakthroughs?
Review together
The core materials of major equipment are all localized
China's first 10,000-ton photovoltaic hydrogen production project was put into operation
On June 30, China's first 10,000-ton photovoltaic green hydrogen demonstration project, the Kuqa Green Hydrogen Demonstration Project, successfully produced hydrogen, marking the first time that China has realized the industrial application of large-scale photovoltaic power generation direct hydrogen production process and engineering complete set of technology.
The project uses Xinjiang's abundant solar energy resources to generate electricity to directly produce green hydrogen, with a hydrogen production capacity of 20,000 tons per year by water electrolysis, which can deliver 280,000 cubic meters of hydrogen. Greenhouse gases are basically not produced in the production process, creating a new path for green hydrogen refining.
At the same time, photovoltaic modules, electrolyzers, hydrogen storage tanks, etcThe core materials of major equipment have all been localizedIt plays a positive role in promoting the development of the domestic hydrogen energy industry chain.
Electricity comes from the sea
The "big windmill at sea" is connected to the grid for power generation
July 19th,The world's first 16 MW ultra-large capacity offshore wind turbineThe successful grid-connected power generation of Fujian offshore wind farm marks a new level in the R&D, manufacturing and operation capacity of China's offshore wind power large-capacity unitsReach the international leading level
It is estimated that under rated working conditions, this 16 MW offshore wind turbine can generate 34 per revolution2 kWh, with an annual power generation of more than 66 million kWh, can meet the needs of 360,000 families of three use electricity for a year.
"Celestial Artifact" +1
On September 27, the annular array solar radio imaging telescope in Daocheng, Sichuan Province successfully passed the process test and was officially completed. The whole telescope is shaped like a huge "thousand-eyed dzi".It is currently the world's largest integrated aperture radio telescope.
As a "celestial artifact", the project is led by the National Space Science Center of the Chinese Academy of Sciences, and is one of the landmark equipment of the second phase of the Meridian Project of major national scientific and technological infrastructure, which will carry out continuous monitoring of the sun and forecast and warn of space weather.
In the future, this "sky-watching artifact" will also be jointly monitored with Guizhou's FAST China Sky Eye, as well as China's compound eye and Sanya's incoherent scattering radar, and play an important role in the monitoring, defense and early warning of low-frequency radio, pulsars and asteroids.
100% independent intellectual property rights in China
The main line of the Shenzhong Passage runs through
On November 28, the main line of the Shenzhen-Zhongshan Corridor, a major national project, was completed, and another new landmark in the Greater Bay Area jumped out of the sea.
The Shenzhen-Zhongshan Corridor spans the east and west banks of the Pearl River Estuary, connecting Shenzhen, Guangzhou and Zhongshan, integrating "bridges, islands, tunnels and underwater interconnection".It is currently the most difficult cross-sea cluster project in the world, with 100% China's independent intellectual property rights.
During the construction process, the project was recordedThe world's first extra-long two-way eight-lane submarine immersed tunnel and many other "world's best".。It is planned to be ready for traffic in June 2024, when the travel from Zhongshan to Shenzhen will be shortened from about two hours to less than 30 minutes.
Independent research and development of new !
A new generation of domestic CPUs was released
On November 28, a new generation of domestic CPUs, Loongson 3A6000, was released in Beijing. Loongson 3A6000 adopts China's self-designed instruction system and architecture, without relying on any foreign authorized technology, and is a new generation of general-purpose processor independently developed and controllable in China, which can run a variety of cross-platform applications.
Loongson 3A6000 can meet all kinds of large-scale and complex desktop application scenarios, and its launch marks that China's self-developed CPU has reached a new height in terms of independent controllability and product performance, and its performance has reached the international mainstream product level.
Another "global first"!Officially delivered
On November 29, the large-capacity battery hybrid ro-ro passenger ship built by China State Shipbuilding Group was officially delivered. This delivery also means that the two ships in the world's first batch of large-capacity battery hybrid ro-ro passenger ship orders have been completed.
The ship isThe world's first RoPax ship with a double-head designThe bow and stern structures are completely symmetrical, each with a cab and superior manoeuvrability. The total length of the RoPax ship is 2305 meters, 30 meters wide8 meters, full load can transport 1,500 passengers and more than 700 vehicles of various types. There are more than 10,000 square meters of public areas on board for passenger activities.
The high-capacity battery hybrid RoPax vessel is equipped with the equivalent of the battery capacity of 150 passenger electric vehicles combined, which allows the vessel to use all-electric propulsion and achieve zero emissions when sailing offshore.
China's first batch of unmanned maritime affairs
Listed in Weihai, Shandong
On November 29, China's first batch of unmanned maritime personnel were compiled in Weihai, Shandong, which effectively improved the dynamic control ability of water traffic and the emergency response level of ship accidents.
The two unmanned aircraft with a maximum remote control distance of 150 kilometers, a maximum cruising range of 400 kilometers, and a maximum flight speed of 150 kilometers are equipped with advanced equipment such as photoelectric pods, airborne ship automatic identification systems, emergency throwing and directional sound amplificationIt is currently the most advanced unmanned system in China's maritime system
The world's deepest and largest ultra-deep underground laboratory
Officially put into operation
On December 7, the civil works of the second phase of the Jinping Underground Laboratory of China were completed, and the experimental conditions were metThe world's deepest and largest extremely deep underground laboratory was officially put into operation
In the future, Jinping Facility will be developed into a world-class deep-earth scientific research center covering particle physics, nuclear astrophysics, cosmology, life sciences, rock mechanics and other interdisciplinary disciplines, helping the national science and technology innovation platform to "leapfrog up".
Innovation, improvement, breakthrough.
Super engineering and great power heavy weapons.
It demonstrates China's hard core strength in various fields.
Let's work together for the great builders.
Kudos with the amazing power of China!
