The "progress bar" continues to refresh

The second domestically produced large cruise ship

"Aida Huacheng" was officially delivered

On November 6, the second domestically produced large cruise ship "Aida Huacheng" was officially delivered in Shanghai, marking the completion of a key leap in domestically produced large cruise ships from single-ship breakthrough to serial construction.

"Ada·Flower City" is fully upgraded on the basis of the first domestically produced large cruise ship "Aida·Magic City". It is longer in size, has more space, and has an experience that is more in line with Chinese people's habits.

A set of hard-core data will help you understand the strength of this "Flower City on the Sea"↓

The total length is 341 meters, which is 17.4 meters longer than the "Aida·Modu". The hull is slender and the sailing is smoother.

The hull width is 37.2 meters, which is more than the lateral width of a 12-story ordinary house. The wide hull greatly improves the stability of the ship.

The total tonnage is 141,900 tons, which is 14 times that of ordinary 10,000-ton giant ships.

The entire ship is divided vertically into 16 levels of tourist activity areas, covering everything from accommodation, dining, and entertainment to sports, shopping, and parent-child activities.

The total number of rooms is 2,130, which is equivalent to the total number of rooms in 6 small and medium-sized five-star hotels.

The maximum capacity is 5232 guests.

All guest rooms on the ship have been professionally tested for noise reduction and shock absorption. Under the maximum sailing condition of the ship, indoor noise is strictly controlled within 45 decibels.

The ship also has 28 restaurants and bars, a large theater with 800 people, a 200-meter circular sea runway, etc.

Chinese space station

Refreshing the record for the coldest substance in mankind

On November 6, the Space Application Engineering and Technology Center of the Chinese Academy of Sciences released the latest scientific research results of the Chinese Space Station. The Chinese scientific research team used the ultra-cold atomic physics experiment cabinet of the China Space Station's Mengtian capsule to prepare the coldest substance known in the universe, setting a new record for the coldest substance in mankind.

This time, the result of the China Space Station ultra-freezer is 9.7 picokelvin and the sustainable observation time is 7 seconds. What is the concept? One picokelvin is equal to one trillionth of a Kelvin, which is 14 orders of magnitude lower than daily room temperature. In general cold atom experiments on the ground, the atomic temperature is usually only on the order of micro-Kelvin. This result is equivalent to amplifying the detection signal by 1 million times. In this way, it is theoretically sensitive enough to detect extremely weak gravitational disturbances caused by a one kilogram object ten meters away.

The world’s highest grid-connected solar thermal power station

On November 6, the first unit of CGN’s “zero-carbon” solar energy storage thermal power demonstration project located in the Ngari region of Tibet was connected to the grid to generate electricity. This is the highest grid-connected solar thermal power station in the world.

The project is located in Gar County, Ali Prefecture, Tibet, with an average altitude of 4,300 meters and a total installed capacity of 150,000 kilowatts. It consists of a 100,000 kilowatt photovoltaic power station and a 50,000 kilowatt photothermal power station. Once fully completed and put into operation, the annual power generation is expected to be approximately 270 million kilowatt-hours, and the annual carbon dioxide emissions can be reduced by approximately 168,200 tons, providing support for ensuring energy supply and green and low-carbon development in the Ali region.

Domestic first set

Complete set of ultra-deep shaft intelligent welding equipment put into use

On November 3, my country’s first set of intelligent welding equipment for pressure steel pipes dedicated to ultra-deep shafts was officially put into use at Songyang Pumped Storage Power Station in Zhejiang.

The equipment is independently developed for the extreme working conditions of narrow deep wells in deep underground engineering, filling the shortcomings of automatic welding of high-strength steel pipes in ultra-deep shafts, and taking another critical step towards the independence of my country's ultra-deep underground engineering equipment.

With this set of equipment, pressure steel pipe installation can realize integrated operations of hoisting, welding, flaw detection, and anti-corrosion. The welding speed can reach 30 to 50 centimeters per minute. The welding efficiency is increased by more than 65% compared with traditional manual welding, and the one-time pass rate of welds reaches 99%.

The first domestic article

Hydrogen energy sealing material production line trial run

Recently, China's first intelligent production line for hydrogen energy sealing materials was put on trial in Huantai County, Zibo, Shandong.

A local new materials company spent three years tackling key problems, making breakthroughs in both material formulation and production technology, and achieving full domestic substitution of its core products. The newly built intelligent production line replaces manual operations with automated processes, solving the industry's chronic problem of uneven products. The hydrogen energy sealing gaskets produced by it have high rebound and small creep. They are used in electrolytic water hydrogen production electrolyzers and have a service life of up to 10 years.

In the hydrogen energy sealing segment, Chinese companies have achieved product independence and participated in formulating the industry's "safety standards." The importance of this "domestic first" production line in Zibo is not only in terms of production capacity, but also in complementing a long-neglected but crucial piece of the sealing puzzle in my country's hydrogen energy industry chain.

The world's first

4,000-meter-level floating wind power system completes first city flight

On November 6, the world's first 4,000-meter-level floating wind power generation system was successfully tested in Yueyang, Hunan Province. This was the first time that a 4,000-meter-level floating wind power system completed a flight test in an urban scene.

The S4000 floating wind power generation system that has completed the flight verification this time is 67 meters long, 40 meters wide, and 23 meters high. It can reach an altitude of 4,000 meters, has an output voltage ranging from 10 kV to 35 kV, and has a designed service life of 20 years.

This system uses a helium-filled floating platform to send lightweight power generation modules to an altitude of several thousand meters, using stable high-altitude wind resources to continuously generate electricity. The generated electricity is then returned to the ground via mooring cables.

The Great Power Project is advancing steadily

Frontier exploration continues

The innovation “progress bar” continues to move forward

More breakthroughs are worth looking forward to!
