In the field of burglar alarm, there are many popular perimeter protection technologies at present, such as vibrating cable, outdoor three-authentication probe, leaking cable, tension fence, electronic fence, infrared correlation and other technologies.
At present, China's railway industry is developing at a high speed, the railway network is becoming denser and denser, and the number of railway platforms is increasing.
Fiber laser technology shows broad application prospects and great technical advantages in high-speed and large-capacity wavelength division multiplexing fiber communication system, high-precision fiber sensing technology and high-power laser.
The mechanism of laser sterilization is based on the interaction between laser and substance. Laser can be used for sterilization and disinfection. Different doses and wavelengths can kill different bacteria, viruses and various parasites.
Characteristics of lasers with different wavelengths Blue laser: The penetration depth is the shallowest.Green laser: The penetrating power of tissue is stronger than blue light intensity.
Infrared ray is an electromagnetic wave with a wavelength between microwave and visible light. It has the same essence as radio wave and visible light. Its wavelength is between 770 nm and 1 mm, and it is located outside the red light in spectrum.
Food packaging has the highest requirements in the packaging industry, and it is closely related to people's daily life, so it has always been highly concerned by people. With the continuous improvement of living standards.
