5Radio: The invention of the radio was a milestone in the 20th century, which enabled people to receive and listen to audio signals from radio stations by converting electrical energy. With the application of DSP technology, the traditional analog radio is gradually replaced by more efficient digital radio, marking the arrival of a new digital era of radio technology. Night vision: The invention of night vision greatly changed the way of seeing and fighting at night.
6. Television: The birth of television is one of the greatest inventions of mankind in the 20th century. Nylon: Nylon is the world's first developed a synthetic fiber. Plastic: The invention of plastic can be said to be 20The great work of mankind in the century. Airplane: One of the most important inventions of the 20th century was the birth of the airplane.
It can be replaced, but the power consumed by wireless charging is too large, and its conversion rate needs to be improved, so wired charging may still be a more common charging method.
Wireless charging can be without a data line because it uses advanced technology, which fully shows our country's superb technology, so wireless charging can be without a data line. With the improvement of science and technology, there are more and more kinds of mobile phones, there is a kind of mobile phoneThe charging method is very strange, that is, wireless charging of mobile phones, wireless charging is the process of converting the current into a magnetic field, and the magnetic field is transmitted through the air and converted into a current to be transmitted to the charging device. Compared with wired charging, wireless charging this way does not seem to be dominant, and the current technical shortcomings are many, such as low charging efficiency, standards are not unified and the cost is higher, which is almost the fatal injury on the road to its popularity.
In fact, it has to be said that the wireless charger does bid farewell to the bondage of the charger line, and it is precisely because of this that it becomes more convenient and convenient, so most people prefer this charging method.Personally think not. First of all, wireless charging is not applicable when driving. Second, wireless charging cannot be used while charging the phone. Finally, when outside, it is more convenient to bring a charging bank to charge the phone wired. Wireless charging is not so applicable when you're driving. If you're in a car, then wireless charging is not so applicable.
After wireless charging, you can better protect the interface of the phone, and you can also have power anytime and anywhere. They will not worry about what to do when they go out without electricity, just put it on the charging site. There areSome people will often drop their phones when using wired chargers, but this will never happen with wireless. This wireless charger is designed to meet the needs of more young people.
1. As early as the 15th century, Greek doctors used the powder ground from willow bark as an herbal version of the original aspirin. By the end of the century, this formula for relieving physical pain had received unprecedented attention, and the German pharmaceutical company Bayer founded the "aspirin" manufacturerThe label became synonymous with the prescription, and in the increasingly busy modern society of the 20th century, the white round pill aspirin played an indispensable role. The inventions of the second century are: television, penicillin, the computer, the microwave oven, the Internet. Television: At the beginning of the 20th century, television began to emerge as a completely new medium. It has changed people's access to information, making it possible for people to watch news and entertainment from around the world at home. Penicillin: In 1928, Alexander Fleming discovered penicillin, an antibiotic that works against a variety of infectious bacteria. <3. Space Shuttle: In 1959, an unmanned Soviet spacecraft successfully landed on the moon for the first time and returned a large number of photographs. In the late 1960s, the United States took the first step toward landing humans on a planet other than Earth with the Apollo moon landing program. The advent of the space shuttle significantly increased the success rate of human travel to outer space, and scientists predict that human travel to outer space will be carried out after the year 2000. The fourth century discoveries and inventions are relativity, quantum mechanics, penicillin, DNA double helix structure, the computer. Relativity Relativity is a theory proposed by Einstein in the early 20th century that subvertsThe classical concept of Newtonian mechanics is presented, and the relativity of time and space is proposed. The theory of relativity revealed the nature of the motion of matter and pushed physics to a new level.
