3DAR globeThe 3D AR globe was an innovative globe product. It broke through the traditional globe model and had the following characteristics:
** 1. Function and Specialties **
1. ** Rich knowledge display **
- With the help of AR technology, various astronomical and geographical knowledge was displayed through 3D animation, just like the world encyclopedia knowledge base. The knowledge included, but was not limited to, astronomy, geography, weather structures, celebrities, animals, plants, scenic spots, and even ancient creatures such as dinosaurs.
- For example, the 14 major topics of the Iswo Open intelligent point reading globe appeared at any time, from national scenery to extreme climate, from ancient dinosaurs to rare animals, from the vast universe to historical celebrities, famous schools, etc. Each theme was a real AR three-dimensional model, allowing children to experience the relevant scenes.
2. ** Multiple interaction experiences **
- Many 3D AR globes had an interaction function that allowed children to understand knowledge in three dimensions. For example, they could rotate the globe 360 degrees to view information from different areas. They could also rotate and enlarge the AR scene at will to interact with the things displayed, such as dinosaurs.
- Some globes were equipped with exclusive applications. For example, the Iswo Open intelligent reading globe with exclusive applications could view AR animations of the solar system and the Earth's structure, clearly showing the deep structure of the Earth and the situation of the solar system.
3. ** Learning Support and Bilinguals **
- It was very helpful for children to learn geography and other knowledge. It was a very good teaching aid for geographical knowledge. Some even provided explanations in both Chinese and English, so that children could learn geography while learning foreign languages.
4. ** Night light function **
- Some 3D AR globe could be used as a small night light after being plugged in, which had a better atmosphere. For example, the Blue Planet globe was a gentle night light when turned on at night.
** 2. Instance of the product **
1. **Funglobe Rolling Ball Touch Lamp AR globe **
- It was produced by a modern enterprise that specialized in producing terrestrial globe for 47 years. The brand had been awarded many honorary awards and cooperated with many brands offline.
- The ball and base were separate and independent designs, light and convenient, and the ball was designed as a roly-doll. The surface of the sphere was double-sided printing. When the light was not on, the original appearance of the Earth could be seen. After the light was on, the administrative area, ocean currents, latitude and latitude lines, etc. could be seen intuitively.
2. ** Iswo's Unlock intelligent reading globe **
- It had six functions: a globe, reading, large model AI dialogue, walking encyclopedia, AR black technology, and real person explanation.
- Gifted VR glasses in a box. Through the APP, you can experience the world in VR, such as the charm of landmark buildings in different cities, the structure of the earth, the solar system, and other content. There will also be interesting explanations in the VR experience to help the child build a systematic geographical awareness.
3. ** DIP ER Beidou intelligent point reading voice 3D AR globe **
- It could be used as a gift for Children's Day, birthday, school, etc. It had a certain educational enlightenment effect, but the price was relatively high. The promotional unit price was 559 yuan.
cu elementCopper was a chemical element with an atomic number of 29. It was an important transition metal element in the fourth cycle of the periodic table.
Under normal temperature and pressure, the appearance of pure copper is rose red, shiny, malleable, odorless, and purple-red when the surface is oxided. Its density is 8.89 g/cm 3 (20 ° C), melting point is 1083 ° C, and it has excellent electrical conductivity, thermal conductivity, corrosion resistance, and good malleability. It can be used for various cold and hot processing. Copper in nature mainly exists in three valences: Cu, Cu2, and Cu3. Among them, the compound of Cu2 is generally white or colorless. Solid copper has high thermal stability, but it is extremely unstable in solution, easy to be oxided or reduced, and its complex has low dissolution. In nature, copper mainly exists in the form of Cu2, which is stable under the conditions of strong oxidization. The compound of Cu3 has strong oxidisation, but its stability is poor.
Copper had little activity and was relatively stable in dry air at room temperature. In humid air, it would react with carbon dioxide and water to form copper rust (verdigris). Under certain conditions, it can react with oxygen, acid, hydrogen, cyanides, and sulfur.
Copper was one of the oldest metals and an important material for the development of civilization. It was widely used in electronics, electricity, transportation, machinery manufacturing, national defense industry, food, agriculture, and other fields. From a historical point of view, as early as 6,000 B.C., copper was used in Anatoria, and around 2,000 B.C., metal smelting technology spread to all parts of the world.
In terms of biology, copper was a trace metal element in the body. It could be absorbed from seafood, organs, meat, grains, water, and other foods. It was absorbed by the small intestine, transported to the liver for metabolism, and then transported to various tissues and organs through the blood. Copper acts as a catalyst and structural cofactor for the corresponding zymes in the body, participating in processes such as oxidoreduction, energy generation, cell metabolism, signal transmission, etc. It also plays a role in cell death mechanisms such as cell death, cardiovascular stress, and copper death. It was also involved in iron metabolism, the formation of colloid, and was a component of many membranes (such as sod and copper-and-zinc-sod), helping to neutralize free radical molecules and maintain cell health. However, excessive copper could cause damage to the body. For example, in patients with diabetes, the imbalance of copper balance would lead to an increase in oxidoxin stress and damage to the anti-oxidoxin mechanism, stimulating the production of inflammatory neurotransmitter and inflammatory factors, thus affecting the occurrence and development of complications of diabetes. It was reflected in complications such as diabetes, myocardipathy, glomerulonepathy, anorexia, and inflammation. In addition, the copper element in preserved eggs should also be taken in an appropriate amount. Overconsumption may be risky for pregnant women, children and other special groups.
