Is good experience and BOM cost a contradiction?

Under the guidance of the standard thinking single wireless charging , the competitiveness of the product and cost control are indeed a pair of contradictions. In the eyes of PVA believers, product competitiveness is a linear value system that adds up to individual configurations, and using more configurations usually means higher BOM costs.

Xiao Zhang told him single wireless charge : "Efficiency and fairness is a pair of contradictions, but also the individual wireless charging we often face the trade-off, not only for the country is more so, such as our country in the 1950s to eat a big cooker, is the practice of attaching great importance to fairness and ignoring efficiency Single wireless charging ; During periods of social change, such as the Industrial Revolution, society generally places greater emphasis on efficiency to promote social progress more quickly.

For example, the current problems to be solved or some problems to be solved, this is the primary and secondary contradictions. To put it plainly in very popular language, if you see that there are some problems to be solved in the title, it is to analyze the primary and secondary contradictions and the nature of something in the problem, the overall situation, is the primary and secondary aspects of the contradiction. Take a very simple example: China's overall development trend is good at present, with rapid GDP growth and a substantial increase in national income, but the CPI index is too high.

is a pair of contradictions and inevitability is a regular, inevitable and unchangeable trend in the connection and development of objective things. Chance is a guestObserve the uncertain trends in the connection and development of things that are not certain to occur, can occur or not occur, can occur this way or that way. Necessity and contingency have their own characteristics: first, the reasons for their emergence are different.

The relationship between compensation incentive and labor cost budget control is like a pair of complex contradictions. They conflict in the following aspects: First, labor cost control is a kind of overall decision, which is based on the overall performance and price of the company, and is a top-down management; On the other hand, compensation incentives are individualized, focusing on the performance of various departments and employees from the bottom upUpward incentive system.

Conflict and disagreement are inevitable in interpersonal communication. When confronted with conflicts, we need to find effective ways of reconciliation to promote mutual understanding and harmony. This article will explain some strategies to properly handle conflict, help people to reach a consensus when facing problems, and maintain good relationships together. Listening and understanding Show concern: In the face of conflict, you should first show the other party that you care and are willing to listen.

What were Edison's inventions

Phonograph: Edison invented the phonograph, which is the firstA recording device capable of recording and reproducing sound. Electric light: One of his most famous inventions was the electric light, and after many experiments, he finally invented a long-life incandescent lamp. Generators: Edison contributed to the development of the electric power system, inventing a variety of generators that increased the efficiency of electricity generation and distribution.

Moving motion picture camera In 1889, Edison invented a moving motion picture camera. The camera uses a pointed gear to drive a 19mm wide piece of non-porous tape, which is moved intermittently and perforated under the control of a ratchet. The camera is driven by an electric motor, and the shutter pivots and staysThe sound machine is connected, and when the camera is running, the phonograph records the sound and realizes the synchronization of the sound and the image.

Edison mainly invented the electric light, the electric car, the movie, the generator, the electric motor, the telephone, the phonograph and so on. His inventions of the phonograph, the motion picture camera and the electric light had a great impact on the world. He is credited with more than 2,000 inventions, including the phonograph, the motion picture camera, and the tungsten light bulb, which greatly influenced the world. In the United States, Edison has 1,093 patents to his name, and he has accumulated more than 1,500 patents in Britain, France, Germany and other places.

Edison invented staySound machines, video cameras, bamboo lamps, giant machines for crushing ore, nickel-iron alkaline batteries, etc. The phonograph is an electric device used to play a record; It was invented by the American inventor Thomas Edison in 1877. The phonograph record was easier to reproduce in large numbers and played for a longer time than most cylindrical recording media, so it has been called one of Edison's greatest inventions. Edison's inventions include the phonograph, the soul telephone, improved light bulbs and electric light systems, automatic telegrams, actigraphs, rechargeable batteries, and more. In 1876, Edison opened a phonograph in New JerseyLopak set up a research lab. A year later, in 1877, Edison invented something unexpected. People called him "the Wizard of Menlo Park," and it made him a real celebrity. In October 1879, Edison finally succeeded in making an incandescent bulb with carbonized fiber as a filament, called "carbonized cotton filament incandescent lamp", followed by a large number of production, and the establishment of a company to set up power stations and transmission grid and other corresponding infrastructure, soon make the light is widely used in the United States.

diy bus card (Beijing), coil material specification problem

1, *47mm. According to the "Urban public transportation IC card Technical Specifications" that the coil can be used to receive the energy of electromagnetic induction, for the IC in the card to provide working energy, bus card coil specifications 79*47mm. The bus card is the CPU card generally used when taking the bus in the city.

2, although this is not an open robbery. But it's definitely a steal. Quite agree with you. I've been in a similar situation. I'm with you.

3, induction electromotive force, proportional to the cross-sectional area of the coil, the number of turns, so the area is 4 times smaller, then the number of turns will increase by 4 times. In order to get a strong enough induced electromotive force, a reliable drive chip, go around 24 times.

4, the student card is the student ID card, the original copy of the household register and two one-inch color photos, the cost is also 10 yuan, a recharge at least 50 yuan, each time is 0.5 yuan. If it is a discount card, go directly to the bus outlet to buy it, do not need to bring documents, only need to bring money on it, the cost is generally 10 yuan, the first time to deposit at least 50 yuan.

2, the large consumption industry refers to: [food consumption] : liquor, pork, condiments, these are must be consumed, not affected by the cycle, often able to cross the bull and bear, just because the organization is now reported, the price is too high, so there is no configuration.

3, according to the meticulous division of Shen Wan, big eliminationThe fee industry includes agriculture, forestry, animal husbandry and fishery, food and beverage, medicine and biology, household appliances, trade and retail, social services, light industrial manufacturing, beauty care and textile and apparel and other nine categories. Let's explore one by one: the food and beverage sector, especially the baijiu sub-sector, is known as the flagship of big consumption, Moutai's market capitalization once exceeded 4 trillion yuan, but it has been hit hard by the market suspicion of its links to corruption.

What did Edison invent?

1, Edison mainly invented the electric light, electric car, film, generator, motor, telephone, phonograph and so on. He inventedThe phonograph, motion picture camera and electric light had a great impact on the world. He is credited with more than 2,000 inventions, including the phonograph, the motion picture camera, and the tungsten light bulb, which greatly influenced the world. In the United States, Edison has 1,093 patents to his name, and he has accumulated more than 1,500 patents in Britain, France, Germany and other places.

2, Edison invented a film camera composed of a phonograph and a camera, under the energy of the motor, the camera's light blocking crankshaft and the phonograph are connected, and the phonograph can record sound when the camera is running. When projected, the phonograph runs in sync with the pictureTo make sound and image appear at the same time. Edison invented the phonograph, the camera, the bamboo lamp, the giant machine for crushing ore, the nickel-iron alkaline battery and so on. The phonograph is an electric device used to play a record; It was invented by the American inventor Thomas Edison in 1877. The phonograph record was easier to reproduce in large numbers and played for a longer time than most cylindrical recording media, so it has been called one of Edison's greatest inventions. In October 1879, Edison finally succeeded in making a carbon fiber as a filament incandescentThe light bulb, called the "carbonized cotton filament incandescent lamp," was subsequently put into mass production, and companies were set up to set up power stations and transmission grids and other corresponding infrastructure, which soon made the light bulb widely used in the United States. 5. Edison invented many things, including, among others, the electric light, the electric car, the motion picture, the generator, the electric motor, the telephone, the phonograph, the creation timeline, the voting counter, the printing press, the sonic analysis resonator, the synchronous transmitter, the wax paper mimeograph, and so on. In 1877, Edison improved on an earlier telephone invented by Alexander Bell and put it into practical use, and soonStarted a telephone company.

6, Edison and his invention (1) synchronous transmitter Early telegraph, a message can only be transmitted at a time, and can not exchange signals at the same time, because Edison itself is a telegraph technician, he began to improve the traditional transmitter, to create a double transmitter, 1874 and developed a quadruple transmitter, that is, synchronous transmitter. At a time when radio was not yet developed, the synchronous transmitter was a major breakthrough.
