Surprising as it may sound, no one really knows what an electron is, and it is this fundamental question that has been driving much of modern physics and ultimately led to the development of quantum field theory. To answer the question "What is an electron?" This problem, you would think the first step would be to observe it. But that's easier said than done. Electrons are too small for us to see -- the smallest thing we can see is … Continue reading "What is an electron? Do you really know anything about electrons?"

A metal laser cutting machine is a kind of mechanical equipment that uses laser technology to manufacture and cut metal. At present, many metal processing manufacturers choose to use laser cutting machines to cut metal. Metal Laser Cutting Service is an important production process in the industrial construction industry. At present, acetylene, propane and other raw materials are used in the cutting process to improve production efficiency and save energy. A so-called metal cutting machine, also known as a metal … Continue reading "What is metal laser cutting? What is the use of metal laser cutting technology?"
In addition to the punch material and the design of the punch itself, what are the causes of punch fracture? 1. The punch hardness is too high, the punch material is not right ---- replace the punch material, adjust the heat treatment hardness. 2. Improper material positioning, resulting in punching punch cutting side, due to uneven force breakage ---- adjust positioning or feeding device. 3.Deep Draw Stamping material does not meet the requirements, resulting in bad angle, resulting in size … Continue reading "Why is the punch of stamping die easy to break?"
A netizen commented that the same phone, Samsung Note9, saves battery power far more when plugged into the mobile card alone than when plugged into the Unicom card alone. Online, wifi is also used in this case. This IS THE BATTERY LIFE OF THE MOBILE CARD INSERTED YESTERDAY AFTERNOON UNTIL 8:20 AM TODAY. Besides SCROLLING news, XIMalAYA LISTENING has been busy, and it still HAS 68% battery LIFE. If that was the case with the Unicom card, it would have … Continue reading "Use mobile phone card, save electricity more than Unicom telecom card?"

The semiconductor diode mainly depends on the PN junction and work. The point contact type and Schottky type, which are inseparable from the PN junction, are also included in the range of general diodes. So what types can it be classified according to its construction? Follow Xiaobian to have a look ~ ⒈ Dot contact diode Point contact diodes are formed by pressing a metal needle on a single chip of germanium or silicon and then passing it through the … Continue reading "What types of semiconductor diodes can be classified according to their construction?"
The Capacitance, also known as the Capacitance, refers to the charge storage at a given potential difference. The symbol is "C". The SI unit is Farad. The commonly used capacitance units are millimetric (mF), micrometric (μF), nanometric (nF) and cuticle (pF). The specific conversion method is as follows: 1 farad (F) =1000 milieu (mF) =1000000 micromethod (μF) 1 micromethod (μF) = 1000 nano method (nF) = 1000000 skin method (pF). Capacitors are mainly used in power filtering, signal filtering, bypass, … Continue reading "Understanding capacitor elements"
