2.RT=real time means real time and is often used to describe the operating system (real-time operating system). RT is actually just a relative concept, which means that the delay is not enough to have an impact. Real-time operating systems, such as VXworks and RTlinux, are often used in the control field.
3.RT means cold ton, which is the unit of refrigeration capacity. Cold tons, also known as frozen tons, represent the cooling capacity required for 1 ton of saturated water at 0℃ to freeze into ice at 0℃ within 24 hours. The frozen ton represents the refrigeration capacity of the refrigerator.
4.Rt = retention time, which is a chromatographic term in analytical chemistry. The time from the beginning of injection to the maximum concentration of the component behind the column, and the time from the beginning of injection to the peak of the chromatographic peak of the component are called the retention time of the component, which is expressed by Rt and often takes minutes as the unit of time.
5.RT-PCR (reverse transcription-polymerase chain reaction) is a technology that combines reverse transcription of RNA with polymerase chain amplification (PCR) of cDNA. Firstly, cDNA was synthesized from RNA by reverse transcriptase, and then the target fragment was amplified by DNA polymerase using cDNA as template.
RT-PCR technology is sensitive and widely used, which can be used to detect the level of gene expression in cells, the content of RNA virus in cells and directly clone the cDNA sequence of specific genes.
