”Big bags, small bags, please go through security check!” Security check is always an essential step when you travel by high-speed rail, airplane, or subway. I wonder if you have ever been interested in this security check machine. What can the staff see on the screen? How do they quickly identify the items in the suitcase? Today, let the editor reveal this secret for you.In the eyes of peers, baggage scanner machines It has good qualities that people covet, and it also has many loyal fans that people envy. https://secuzoan.com/

　　How does the security inspection machine work?

　　

　　Generally speaking, the machine that conveys and inspects luggage is called an X-ray luggage inspection machine. As the name suggests, the security inspection machine uses X-rays to inspect luggage.

　　

　　X-rays are short-wavelength electromagnetic waves that can penetrate objects. The penetration of X-rays varies depending on the thickness, density and material of the object.

　　

　　Everyone should know that X-rays in hospitals are also used by doctors. The penetration rate of X-rays varies according to the density of the structure and tissue. The penetration rate is high in loose areas and low in dense areas. The bones of the human body are denser than the skin and flesh tissue. Therefore, when X-rays are irradiated to the human body, the outline of the bones will be displayed more clearly on the screen.

　　

　　security check

　　

　　The same is true for the security inspection machine that checks luggage. The penetration rate of X-rays on different objects is different. When the suitcase passes through the security inspection machine, the X-rays penetrate the suitcase and display the outlines of different objects on the display screen.

　　

　　At this time, some friends may feel confused: X-ray imaging should be black and white, so why can security inspectors identify different objects so quickly?

　　

　　This question really hits the nail on the head. If you have ever looked at the security check display screen, you will find that the image on it is in color, not black and white.

　　

　　security check

　　

　　Normally, the color of the image formed by X-rays on the film is indeed black and white, just like the X-ray photos in the hospital. The reason why a color image appears on the security screen is that the computer calculates and converts the projection intensity of the X-rays. This is also to make it easier for security personnel to quickly distinguish different objects in a short period of time.

　　

　　Normally, orange represents organic matter such as liquids and sprays; blue represents metals and various controlled knives; and heavy metals or lead, which can completely absorb X-rays, will be displayed in black.

　　

　　Now you should know why the staff will immediately notice and ask you to take out a small pair of scissors in your suitcase; and the water in your backpack will also be asked to take out and drink a sip.

　　There are many steps in makeup, and the makeup tools used in different steps are different. For example, when painting eye shadow, eye shadow brush will be used, and when concealing, concealer brush will be used. So, can the eye shadow brush be used as a concealer? Concealer brush is harder than eye shadow brush, and the brush head is smaller. Concealer is generally paste, but eye shadow brush is not suitable. Let’s learn more about the difference between concealer brush and eye shadow brush.Therefore, this is the choice makeup brush set The reason, there is no denying its positive impact. https://lsmakeupbrush.com

　　

　　First, can the eye shadow brush be used as a concealer brush?

　　

　　The eye shadow brush can’t act as a concealer. The concealer brush is to dip a proper amount of cosmetics, that is, concealer liquid foundation, etc., and then smudge the edge of the concealer, remember to use it a few times. The material of eye shadow brush is not suitable for concealer.

　　

　　Eyeshadow brushes can be roughly divided into five types according to the size of the brush head. Generally speaking, the color brushed by the big brush head is relatively light, which is suitable for a large area of eye socket, and the middle brush head is used to brush the middle color. People with deep double eyelids can get eye shadow on the wide side of the brush. Eyeshadow brush with pencil brush head is generally a necessary tool to draw a gradual feeling at the end of the eye. Small flat brush with long hair is mainly used to enhance the effect of key colors.

　　

　　Second, the difference between concealer brush and eye shadow brush

　　

　　1. In terms of softness and hardness, concealer brushes are generally hard, while eye shadow brushes are softer; In terms of brush head area, concealer brush head is smaller, and eye shadow brush head is bigger; In terms of usage, if you choose a concealer brush, you should adopt a point painting method, and if you choose an eye shadow brush, you should adopt a horizontal painting method.

　　

　　2, concealer brush is mainly used to cover a small area of the face, emphasizing accuracy, so the concealer brush is hard, which is more convenient to apply. The eye shadow brush is used to apply eye shadow, which needs to be applied repeatedly on the eyelids. If the brush head is too hard, it will hurt delicate skin, so the bristles of the eye shadow brush are particularly soft.

　　

　　3. When you need to retouch your makeup, you can dip a small amount of liquid foundation and concealer with a concealer brush and gently apply it to acne marks and other parts. In order to make the concealer and the base makeup blend together better, you can gently wipe the border with a cotton swab, so that the concealer can smudge better and blur the dividing line.

　　

　　4. The brush head of the eye shadow brush is generally larger than the concealer brush, but there are many kinds of eye shadow brushes, and each eye shadow brush is used to apply different parts. Eyeshadow brushes with large area and flat shape are generally used as a base, which can ensure that the edges and corners are taken care of. You can dip it in white or beige, and then apply it across the entire eyelid. A small flat eye shadow brush is generally used to highlight the main color, and is usually used to smear the middle of the eyelid. Eyeshadow brushes with small area and sharp shape are generally used to repair or outline.

　　

　　5. Concealer brush and eye shadow brush have their own strengths. If you want to create a perfect makeup, it is best to buy them together. And whether it is a concealer brush or an eye shadow brush, remember to clean it in time after use, so as to ensure that you still have a clean beauty brush next time.

　　Ultraviolet (UV) rays are a type of electromagnetic radiation that comes from the sun. These rays are invisible to the naked eye but can have damaging effects on the skin and eyes. UV rays are divided into three types:

　　

　　UVA: These rays penetrate deep into the eye and skin. Prolonged exposure to UVA rays can lead to long-term damage, such as cataracts and macular degeneration.

　　

　　UVB: These rays are more intense than UVA rays and can cause immediate harm, such as sunburn. In the eyes, UVB exposure is linked to photokeratitis, also known as “sunburn of the eye.”

　　

　　UVC: These rays are mostly absorbed by the Earth’s atmosphere and do not pose a significant threat to humans.
