No harm. The principle of metal detectors: Metal detectors use the principle of electromagnetic induction, the use of alternating current through the coil, to produce a rapidly changing magnetic field. This magnetic field can induce eddy currents inside metal objects. The eddy current will generate a magnetic field, which in turn affects the original magnetic field, causing the detector to emit a sound. Hand-held metal detectors are designed to detect peopleOr a metal object carried by an object.
No, hand-held metal detectors do not have any harm to the human body and the instrument. Sometimes pregnant women and people with cardiac pacemakers ask not to use hand-held metal detectors for manual inspection, and the security inspector will agree. This does not mean that hand-held metal detectors are harmful to the body and the instrument, only that security personnel can feel at ease for passengers.
Ionizing radiation emits radiation to the outside world, which can affect the human body, while electromagnetic radiation does not. When you take the high-speed rail or subway, there will be a security inspector with a security scanner for a full body check, in fact, this handheld>

2, which copperThe quality is the best, but the price is high. Stainless steel has high strength, strong corrosion resistance, no discoloration, and is a lock material, but the forging performance is not good, and the style and color of stainless steel door locks are relatively single. Zinc alloy has strong wear resistance, corrosion resistance and other properties, and is relatively easy to cast, you can design many styles and patterns, many of the locks on the market are zinc alloy material. 3, the lock body material this involves a lot of professional knowledge and the technology of various manufacturers, the mainland is generally made of iron, steel, stainless steel, zinc alloy, due to the process, the cost of the limit, the lock rod hardness is not enough, often very largeEasy to be cut by tongs, hydraulic pliers. Most people buy locks only look at the shape, and think that it must be good if it is large.
1, the selection of soft light, need to consider the use of the scene, light quality, portability, compatibility and after-sales service and other aspects. First, it is key to define the use case. Different shooting environments have different needs for soft light. For example, indoor photography may focus more on uniformity and softness of lighting, while outdoor shooting may place more emphasis on portability and battery life.
2, softLight lamps are generally recommended to choose between 30 and 120 watts. The detailed explanation is as follows: soft light because of its soft light characteristics, widely used in photography, home lighting and other fields. When choosing the power of the soft light, you need to consider the use scenario and purpose. For photography, the right power can ensure that the light and shadow effect of the photo is natural and soft. For home lighting, soft light can provide a comfortable lighting environment without being too harsh.
3, when choosing live soft light, it is necessary to consider multiple factors comprehensively to ensure the best live effect. First, the brightness of the lights is crucial and must be bright enough for live streamingIn the environment, it is generally recommended to choose a lamp source with higher brightness to ensure a clear picture. Secondly, it is very important to choose a lamp that supports the adjustment of color temperature, which can help you adjust the color of the light according to different shooting environments, creating a more natural and comfortable atmosphere.
4, turn on the two-color temperature four-soft light to enter the camera selfie interface -- the lightning icon in the upper left corner, select "soft light" to turn on the soft light real-time fill light, click "soft light steady" to adjust the color temperature of the soft light. Turn on the dual soft light to enter the selfie screen of the camera - the lightning icon in the upper left corner, select the soft light to turn on the soft light real-time fill light.
5, soft light for the light color requirements, must be soft, warm tone. It is very important for people's eye care. The wattage problem of soft light lamp Selecting a energy-saving lamp with large power can improve the color saturation of the photo taken, and also improve the clarity and noise. According to what you said, it is recommended to choose about 30W energy-saving lamps (pay attention to color temperature). Preferably with a hood. The white balance of the camera can be adjusted to achieve the required effect.
