1. Atomic Nature(1) The Atom is the basic unit of the constituent matter (of course, electron, etc.), so the meaning of the atom represents-"not divided";(2) Atomicity is the rejection of multi-threaded operation, whether multicore or single-core, with atomic quantity, at the same time only one thread to operate it. In short, operations that are not interrupted by the thread scheduler during the entire operation can be considered atomic. For example,

software a color mode, in this mode, processing the image is more convenient, and, RGB stored images than CMYK images to small, can save memory and space.
CMYK mode is a pigment mode, so it belongs to the printing mode, but in essence, there is no difference with RGB mode, but the way of producing color is different. RGB is the additive blending mode, and CMYK is the subtraction process color mode. For example, the display uses RGB mode because the display is an
required for 4K products?
For 4K resolution, it has only horizontal pixel value and vertical pixel value of two attributes, but for the 4K TV and 4K display products, in addition to the resolution to meet the standard, the level of refresh rate can not be ignored. Refresh rate refers to the screen image of the update rate, the previous CRT monitors rely on electronic excitation screen phosphor display image, but because the same time only one pixel is lit, to display a complete image, the moni

The liquid crystal display has radiation, but it is very low.
The principle of radiation is that the current generates a magnetic field to generate an electric field and then generate a magnetic field, so that the infinite cycle of its source is the current so as long as there is radiation, but there is no ordinary display LCD display high-voltage coil, so the radiation is very low.
LCD Bi Chunping Monitor is much smaller. Because it has no high-voltage circuit, no need for high-speed
by the electromagnetic work, time is long, may appear color, show confusion and so on. Therefore, the use of the display should be placed in the distance from other electromagnetic fields, regular (such as one months, etc.) using the degaussing button on the monitor degaussing, but do not pay attention to the use of a repeated, this will damage the display.
3, to avoid CRT display work in a high temperature state
CRT's picture tube as a large heat source of the display, in too high ambient te
Because the display is mainly for people with eyes, and eye vision has a direct correlation with the test project, is the main way to select a monitor. I think the only requirement for the monitor is to look at the eyes not tired, comfortable, so I locked the target in with the eyes have a direct effect on the performance. The direct function of the eyes of the display performance, the monitor is the most important menu performance.
1. Focus
Focusing ability is the indicator of the display, wh
power of the larger household appliances, the display will also be affected by the working state, which is prone to color-red phenomenon; The third is that the display has been used for a long time, some parts of the interior have been aging or damaged, For example, if the display inside the electron gun aging, or the internal degaussing line is damaged, the monitor can not be in normal working condition; The four is the monitor and the display card
only go to the display after the cover, reseat the interface of the board, the most taboo is to open the LCD panel. Because the assembly of the LCD panel is carried out in the dust-free environment, open not only may let inside into the dust, affect the display effect, may even display directly scrapped.
Four, do not use screen saver
In the CRT era, many people like to use screen saver, because this can avoid the electron beam long-term bombardmen

Canon G1X Mark II is equipped with a highly sensitive 1.5 "CMOS image sensor (about 18.7x12.5mm) near the SLR camera aps-c size, which means that more light signals can be captured and better signal-to-noise ratio is achieved." The Canon G1X Mark II CMOS uses the chip internal noise elimination technology, may eliminate the fixed type noise point, simultaneously unifies in the pixel point to use the entire
In many cases, pagination also brings in query conditions, where queries are often not fixed. For example, the common search needs to be based on the user query keyword to retrieve, in the search results too much, you need to make the search results reasonable pagination.
thinkphp paging can be easily implemented to support the parameters of the unfixed query. The implementation is to assign values to the parameter property of the paging class or to instantiate the paging class directly when th
talking about the color mode
Do you have the feeling that a vivid and colorful image is printed through a color inkjet printer, and the color becomes dark and ugly, even though the printer is of high quality output? But before you blame your printer, I want to ask, what color format is your image?
"Color is color, what's the format?" ”
Yes, there are various forms of color.
Open your Photoshop and look at the mode item under the Image menu, which has a long list of names, what are those? Let's g
Recently used electron platform to do a Web desktop applet, through this small program can generate and verify the server each node needs the INI file. Because the server has a wide range of nodes, so will generate multiple INI file, also put forward a demand, the multiple INI file compressed into a zip back to the user.This is my first JS Web desktop app, I can't help but share:

According to various references to introduce the corresponding CSS. For example, the list page does not require a table to be decorated, so it does not introduce table.css. To conserve the amount of code.
