When it comes to construction in China, it is indispensable to talk about decoration, and the decoration materials of houses are a mixture of various organic compounds. After the decoration of the house, it often needs to be ventilated and left for a period of time before people can go in to work or move…

Traditional solvent-based coatings contain large amounts of volatile organic compounds, which cause serious pollution to the environment. As people’s awareness of environmental protection increases, traditional solvent-based coatings can no longer meet the requirements of increasingly stringent environmental regulations. Under this situation, light-curing coatings emerged and entered the public eye. Light-curing coatings have the characteristics of…
Sensors used in medicine are mostly electronic, which are not suitable for many medical procedures, especially in hyperthermia treatments with high microwave (radiation) frequencies, ultrasonic fields or laser radiation. Because the metal conductors in electronic sensors are easily disturbed by electromagnetic fields such as current and voltage , they can cause thermal effects around the…
Hypothermia refers to a state in which deep body temperature (rectum, esophagus, tympanum) is lower than 35 ° C . Hypothermia can lead to death directly or indirectly. If the body temperature drops below 32 ° C , human organs will not be able to metabolize and work normally. Biologically, animals are divided into two…

Temperature is a physical quantity that measures the heat and cold of an object. In people’s production and scientific research projects, many are carried out at specific temperatures, which is closely related to people’s lives; humidity refers to the relative humidity of the air, generally used as %RH express. Temperature and humidity are closely related.…
How #1 charging pile works The alternating current is input from the three-phase power grid and converted into direct current through the bridge uncontrollable rectifier circuit . After being filtered by the LCR circuit, it is sent to the high-frequency DC-DC power converter. The power converter outputs the required DC voltage after direct-to-direct conversion .…
At factory oxygenation stations, safe operation is crucial. Therefore, attention should be paid to the use of oxygen measurement systems, oxygen alarms or handheld oxygen detectors to prevent explosion accidents caused by excessive oxygen concentration. The main task of the oxygen filling station is to put the produced oxygen into high-pressure oxygen cylinders through an…
SOE signal: sequence of events (resolution not greater than 2ms), record the time of occurrence of events ( switch or protection action) one by one in order, this is the sequence of events record. COS signal (non-SOE): remote signal displacement (without time stamp). The SOE signal is sent with a time stamp at the station…
