Along with the continuous development of economy in our country, most areas begin to produce electric power equipment, which makes the national grid electric power output insufficient, coupled with the aging of the power output facilities, eventually causes the voltage at the end of the circuit to be too low, which brings great influence on the stability of laser output. The stable output of laser energy is a necessary condition for laser production.

Ultrasonic generator common failure and maintenance methodsUltrasonic generator is a kind of equipment that converts the mains power into the corresponding high-frequency alternating current of the transducer to drive the transducer to work. It is an important component of the high-power ultrasonic system. It can also be called electronic box, ultrasonic driving power supply and ultrasonic controller. Although the ultrasonic generator can also be called the ultrasonic drive power, but in fact, the ultrasonic generator is only a part of the ultrasonic drive power.

Influencing factors of inductance saturationA key question is how to ensure "fast enough", that is, what factors influence switching off the tube quickly to avoid the consequences of inductance saturation? This may be the ultimate determinant of the volume and price of the inductor, so it is important to have a good understanding of the response time issue.1. All current limiting loops require a certain time response.

A key query is how to make sure "fast enough", that is, what elements affect switching off the tube rapidly to keep away from the penalties of inductance saturation? This may also be the last determinant of the quantity and charge of the inductor, so it is vital to have a exact appreciation of the response time issue.1. All present day limiting loops require a positive time response.

Why does melt-blown cloth need static electret equipment?01 Why does melt-blown cloth need static electret equipment?Electret electrostatic adsorption is to capture coronavirus droplets through the coulomb force of charged fibers.

Selective photothermal decomposition(Selective Photothermolysis)As early as 1983, a scientific paper published by two scholars, Anderson and Parrish, proposed "selective photothermal decomposition". This is a very important concept for the development and application of laser in dermatology.

As early as 1983, a scientific paper posted by way of two scholars, Anderson and Parrish, proposed "selective photothermal decomposition". This is a very necessary thought for the improvement and software of laser in dermatology.

What is the principle of pulsed strong light sterilizationPulsed strong light is the synergistic action of visible light, infrared light and ultraviolet light on microorganisms, which can destroy the cell wall and nucleic acid structure of microorganisms, thus killing microorganisms. Pulsed strong light has obvious bactericidal effect on mold, gram-positive pathogenic bacteria, Gram-negative pathogenic bacteria, aerobic bacterial spores and fungal conidia, Staphylococcus aureus, Bacillus subtilis, yeast and so on.

Pulsed bright light sterilization, what is the status of this field?Pulsed strong light has been successfully used in air disinfection, food and beverage sterilization. Because of its sterilization speed, has a unique advantage, and will not change any ingredients of the material, does not affect the color and taste of the material.

Precautions for using laser and colored light◇ In the course of optical treatment, the operator should minimize the potential risks to the person present and the possible side effects to the customer◇ During the course of treatment, unauthorized persons are forbidden to enterAll reflective materials and inflammable materials should not be placed in the treatment room, such as mirrors and reflective glass objectsCarbon dioxide extinguisher should be placed in the room◇ Beauty care center should keep the fire outlet unblockedDoors should be kept closed and Windows should be covered with light -
