The working principles of the 2D and 3D are different. You can refer to the following explanation:
Two-dimensional refers to the fictional two-dimensional world that usually appears in anime, comics, games, and other media. In the 2D world, characters, scenes, and things were flat, and the colors and shapes were simple geometric shapes. The working principle of 2D was based on the projection principle by projecting an image onto a two-dimensional plane to create a virtual world.
The three-dimensional world refers to the real world we live in. In the three-dimensional world, characters, scenes, and things were all three-dimensional, and the colors and shapes were all complicated. The working principle of the three-dimensional world was based on the principle of perspective. By observing an object from different angles and distances, one could obtain its shape, size, position, and other characteristics.
Therefore, the difference between the working principle of 2D and 3D was that they were based on different principles and presentation methods.
The working principle of oil extraction included geological exploration, drilling, oil extraction, and transportation. The location and nature of the oil reservoir can be determined through geological survey and geological survey. Well drilling was the process of passing a drill bit through the earth and into the oil reservoir. Oil extraction was the process of extracting oil from a reservoir. Transportation was the process of transporting the extracted oil to its destination. The specific mining methods included natural pressure mining, artificial pumping, water flooding, and gas flooding.
Bluetooth works by connecting devices through radio waves, allowing them to communicate over short distances. The Bluetooth device includes a Bluetooth module, a Bluetooth radio, and software. When two Bluetooth devices wanted to communicate with each other, they needed to pair up. Communication between Bluetooth devices was carried out in a short-range temporary network that could accommodate two to eight devices. After the network environment was successfully created, one device would be the master device, and the other devices would be the slave devices. Different types of Bluetooth technology had different versions of the core specifications. Bluetooth uses the 2.4-gigasecond radio frequency band for communication, which is divided into multiple small channels to avoid interference. Bluetooth's global usefulness and low power requirements made it a popular standard for connecting all kinds of devices, from consumer electronics to business applications to Internet of Things devices.
The working principle of the rainwater intercepting hanging basket device was to use gravity to separate the dirt in the rainwater and settle it at the bottom of the basket, while the clear water flowed out from the top of the basket. The device collected rainwater and sewage through a basket-like object, while preventing sewage from entering the rainwater pipe, reducing environmental pollution. This device usually consisted of a basket and a support frame. The basket was usually made of plastic or stainless steel, and its shape and size were designed according to actual needs. When using this device, the bottom of the basket needed to be cleaned regularly to prevent blockage and odor. At the same time, the integrity and cleanliness of the device needed to be checked regularly to ensure that it was functioning properly.
The working principle of a full-text search engine can be summarized as the following:
Full-text Search: Full-text search engines are not limited to the title or keywords of a document or web page, but can search the entire content of a document or web page, including passages, sentences, and the entire text.
2. Semantics analysis: Full-text search engines use natural language processing technology to analyze the content of the text to understand the meaning and logical structure of the text in order to provide more accurate and useful search results.
Full-text index: Full-text search engines usually create an index to store the content of documents or web pages in the database for quick search and retrieving. The index usually contained the title, author, date, keywords, and other information of the document.
Multi-language support: Full-text search engines usually support multiple languages and can search documents or web pages in different languages. This helped to expand the search range and improve the accuracy of the search results.
Personalized Search: Full-text search engines can provide customized search results based on the user's search history, preferences, language, and other factors. This can improve the user's search experience and help the user better understand the search results.
These are the main features of a full-text search engine, which can help users find the content they need faster.
The principle of bleachings was to make objects lose their color through the oxidisation properties of bleaches. Different types of bleaches had different principles. The principle of the bleaching-powder was that the bleaching-powder would produce hypochloric acid when it came into contact with water. The hypochloric acid could catalyze the coloring matter, thus achieving the purpose of the bleaching-powder. The principle of hydrogen dioxide was that hydrogen dioxide was a strong oxidiser. It could destroy the " chromophore " inside the organic color substance and cause it to lose its original color. The principle of the absorption bleachings was that the substance had a large surface area, which could absorb the dye and make the substance fade. Other bleaches such as sulfur dioxide and ClO2 had similar principles. In general, bleaches change the color of objects or fade them through an oxidization reaction.
The principle of reducing bleaches was to make use of the reduction effect of the dye to fade. The color of organic matter was produced by the color groups contained in its molecules, and the color groups contained unsaturated bonds. The reducing bleaches release hydrogen atoms, causing the saturated bonds contained in the coloring base to become single bonds, and the organic matter would lose its color. This kind of bleacher can make the coloring in food decompose and fade through reduction.
The eye of a typhoon was a special area in the center of the typhoon. The formation principle was that the wind inside the typhoon rotated counterclockwise, causing the air in the center to rotate. The centrifugal force generated by the rotation and the wind force rotating toward the center balanced each other, resulting in a windless phenomenon within dozens of kilometers of the typhoon center. In addition, the air in the eye area of the typhoon sank and warmed up, causing the clouds to dissipate and the rain to disperse. The weather was clear.
There were many ways to prepare the bleachers. One of the common methods was to add Cl2 into water to form Cl2 and Cl3. This kind of bleachers used its strong oxidization ability to vaporize the "chromophore" inside the organic color substance, causing it to lose its original color. The other method was to prepare the bleachers by vaporizing salt water, which would produce both NaClO and NaOx. The content of the bleachers could vary depending on the preparation method, and was generally between 4-15%. In addition, the active ingredients in the bleachers were mainly the two main ingredients, namely, the hypochlorites and the chlorites. In general, the principle of the preparation of the bleachers was to use the strong oxidization of the bleachers to achieve the bleachability of the colored substances.
The construction principle of Xuankong Temple was to distribute the weight of the building on the supporting structure to achieve the effect of hanging on the cliff. Xuankong Temple used the principles of mechanics to insert flying beams as the foundation, relying on the rocks as the hidden support. The beams and columns were one body, and the corridors were connected to the left and right. The plank road that looked up at the sky was only supported by a few vertical and horizontal logs. The true center of gravity of Xuan Kong Temple was supported by the hard rock, using the principles of mechanics and the structure of the flying beam. In addition, the wood used for the flying beams of Xuankong Temple was the local specialty hemlock wood. It was soaked in tung oil before use to prevent corrosion and insects. These special architectural designs and materials allowed Xuan Kong Temple to remain standing for thousands of years and become one of the world's greatest architectural miracles.
