what is nixie tube

Power supply design, or driving circuit, it is inevitable to use the field effect tube, that is, what people often sayMos. Mos have many types and functions. For power supply or driver use, of course, it is to use its switch function. Regardless of the n-type or p-type MO

chain today? What is the high quality of the chain? Just look at the so-called outside the chain of the real role! We first answer a question: what is the outside chain to do, why to give a page to do outside the chain? Look at Google and Baidu's optimization guide said outside the chain

key, out = 0. when the key is disconnected, out =? Obviously, when out is suspended, VCC can be output, which can be measured by a gauge,This VCC is produced by R1 "pull-up". As the name suggests, R1 is the pull-up resistance. The size of the pull-up resistor depends on the requirements of the output load. Generally,

accumulated good experience of technology, in their respective fields are big open hands and feet, income is basically close.In the future, the road of technology more and more difficult to go, after all, to do the technology needs a lot of time and energy, otherwise it will not keep up with the current era of technology updates, do business, customer base is growing, experience more and more rich, who's i

What is the basic computer system and what is the basic computer system? What's the operating system? First, we need to know,Why is there an operating system?. A modern computer system consists of one or more processors, primary storage, hard disk, keyboard, mouse, display,

Sometimes our monitor will appear ambiguous situation, this kind of situation is more common, encounter this kind of situation, what should we deal with the malfunction of the monitor when we encounter the ambiguity? The display of the content is ambiguous that the CRT focus is not good, resulting in poor focus on the

phenomenon. Graphics compatibility failure generally occurs in the computer just installed or after the upgrade, more common in the motherboard and video card incompatible or motherboard slots and Kakin fingers can not be fully contacted. Graphics compatibility failure is commonly used to detect the substitution method, the general use of the replacement of the video card to troubleshoot problems. (3) video card component damage failure: The failur

platform, so what Java so-called cross-platform is to install different JVMs on different platforms, and the. class files generated on different platforms are the same, and the. class file is then interpreted by the corresponding platform JVM as the corresponding platform's machine code execution.Finally, the difference between the machine code and the bytecode

What does the A-share fusing mechanism mean? A-share fusing mechanism means that when the Shanghai and Shenzhen 300 index triggers a 5%-fuse threshold, the transaction is suspended for 15 minutes, triggering a 7%-fuse threshold at any time of the day, and the transaction will be suspended until the closing period. When will the A-share fusing mechanism be implemented? A-share f

What is a voltage-adjustable power supply? What is the principle of voltage adjustable power supply? The voltage adjustable power supply is based on the regulated switching power supply to increase the voltage, so that the output voltage can be adjustable in a large range (

What is the difference between an object in a Free state and an object in a transient state. Answer one: There are 3 types of Hibernate objects: Transient (Transient), persistent (persistent), and off-state (Detached). Objects that are in persistent state are also known as PO (Persistence object), and instantaneous and de-tube objects are also known as VO (Value

What to do if the ASUS motherboard is not lit? Reason Analysis and solution: BIOS repair steps that are not lit by the motherboard: Typically, the new BIOS on the motherboard fixes some bugs in the older BIOS, corrects the known compatibility issues with certain hardware and software, and adds support for new hard drives, such as increased support for large-capacity hard disks and high-frequency CPUs. Th

main line of development. In terms of operational efficiency, PHP is slower than the latter. In practice, however, the impact on most applications is negligible. Operational efficiency is important, but the difference between faster and faster is not worth much to the app experience. In today's fast-changing informati

carrier. The P-tube is hole-conducting, and the N-tube is electron-conducting. The mobility of electrons is greater than that of holes. Under the same electric field, the current of N-tube is
