Each donor yard is ionization with a free
frequency is the vertical scanning frequency (field frequency) of the monitor. It refers to the number of times the electron gun scans the entire screen per second, in Hz. For a CRT display, the image displayed on the CRT display is composed of many fluorescent points. Each fluorescent point emits light under the hitting of the electron beam, but the time for the fluorescent point to emit light is very sho
"Coding optimization Editor", which is available for download to all developers free of charge and offers Mac OS and Linux versions.
News Excerpt Two:
First of all, this Visual Studio code (hereinafter referred to as Vscode) is an editor with a GUI, which can only complete simple code editing functions, not an integrated development environment (IDE)
So don't know if you and bastard first heard the news when the same feeling, is Microsoft suddenly released such a tool? Not on

Now the heat of the material science of nano-technology is that a lot of material fine to nano-scale will show a lot in the conventional order of magnitude can not show the nature. We can even count the atoms in the order of magnitude of the nano. Therefore, the nanometer level is also called atomic level.Are the atoms that make up the DNA molecule, w

The photon, you are so concise, but contains the universe of the origin and true meaning, all the complexity in front of you are easy to laugh. I praise the photon, but also want your brilliance, your selfless, your tolerance, your insipid, your great character purify my heart, heal my wounds, suppress my desire.Photon ah, in the DNA spiral chain of life, I seem to see your figure, tr

assumptions one by one1. The world is not deterministic: below the atomic scale, you can only predict probabilities, for example, you cannot determine where an electron is, but what the likelihood is.2. Whether it is light or matter, there are wave-particle duality.3. In certain circumstances, the physical quantity is discrete, for example, time, quality, length, there is a minimum value, below this value, people do not know what the meaning of him.4
signal, so it must be corrected.In the TV and graphics monitor, the electron beam and the image brightness generated by the picture tube are not linearly changed with the input voltage of the kinescope, and the electron flow is changed according to the exponential curve compared with the input voltage, and the input voltage index is larger than that of the electron

problem:We should all know that a solid substance, if seen from within the atom, is actually empty. Because inside the atom, the atomic nucleus and the electron volume add up to less than 1000000000 of the atomic volume. Moreover, there is no evidence that nuclei and electrons can be passed by photons! Therefore, any object transparent is normal! But why is it that most physical manifestations are non-transparent? In fact, with the current science ca

Introduction: The effect of bonding bond between materials on the material ability
In all solids, atoms are bonded together by bonds. The key enables the solid to have strength and corresponding electrical and thermal properties. For example, strong keys result in high melting points, high modulus of elasticity, short atomic spacing, and low coeffic
Select the advantages of a flat panel monitor.
1, display high quality
Because each point in the LCD monitor is received after the signal has been maintained that color and brightness, constant glow, rather than the cathode ray tube display (CRT) need to constantly refresh the highlights. Therefore, the high quality of the liquid crystal display and will never blink, the eye fatigue to the lowest.
2, a small amount of electromagnetic radiation

Screen refresh frequency is actually a very abstract head, it is a graphic image on the screen by the electron beam hit and light-emitting fluorescence points, because the cathode ray tube in the phosphor by the beam after the light of the time is very short, so the electron beam must constantly hit the phosphor to make it continue to glow. The electron gun start
very small, but over time will lead to circuit distortion, short-circuit, leakage and interference phenomena. At this time the CPU will appear abnormal operation, its function is affected, and then is reimbursement. The high temperature will make the atomic heat movement intensifies, increases by the electron to cheat the probability, at room temperature, every 20 degrees, the electron migration intensity
, a large number of mainstream televisions have been manufactured by the same technology, namely, cathode ray tubes (CRT ). CRT is mainly composed of Electron Gun, deflection coil and cathode ray tube. Because the cathode ray tube is made of glass, it is very fragile, and the screen jitter is imperceptible, but its fatal weakness is not the above, but its size is too large. One rule of CRT technology is that the larger the screen area, the longer the
