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 elec...
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 ar...

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 ...
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 out...
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...
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 ti...
Nitrogen, with the chemical formula N₂, is usually a colorless and odorless gas, accounting for about 78% of the volume of air (about 21% of oxygen). Only about 0.02 volume of nitrogen is dissolved in 1 volume of water. High-purity gases play an important role in modern industry. High-purity nitroge...
