The insulated car can be called a refrigerated truck, which is a special vehicle for transporting perishable goods such as fish, meat, fresh fruits and vegetables. These goods need to maintain a certain temperature, humidity and ventilation conditions during the transportation process. Therefore, the body of the heat preservation car is equipped with heat insulation material, and the vehicle is provided with a cooling device, a heating device, a temperature measuring device and a ventilation device, etc., and has refrigeration. , insulation and heating three properties. First, the working principle of the insulation car Centralized power supply from power generation vehicles, centralized refrigeration of refrigeration vehicles, use of ammonia as refrigerant, and brine as refrigerant; each machine is equipped with refrigeration equipment for refrigeration separately, using Freon as refrigerant, forced air circulation; The freezer plate, which is a container for accumulating coolant at the top of the car, is "cooled", so it is called a freezer plate. Each cargo vehicle has 14 freezer plates that can run continuously for 100 hours when the temperature inside the car is kept below -180 °C. There is also a temperature regulating plate on the car, and the temperature inside the car can be adjusted within the range of -12 °C ~ +5 °C. Second, the application of insulation car A special vehicle for transporting perishable goods such as fish, meat, fresh fruit and vegetables. These goods need to maintain a certain temperature, humidity and ventilation conditions during the transportation process. Therefore, the body of the heat preservation car is equipped with heat insulation material, and the vehicle is provided with a cooling device, a heating device, a temperature measuring device and a ventilation device, etc., and has refrigeration. , insulation and heating three properties. Third, the characteristics of the insulation car The whole vehicle can maintain the specified temperature and humidity evenly, and it is easy to adjust and control, which can fully guarantee the quality of cargo transportation; no need to add ice and ice equipment in operation, save money, accelerate vehicle turnover, reduce transportation cost; The length of the journey and the limitation of the vehicle's residence time during transportation ensure the safe delivery of the goods. The exterior of the insulated car is painted in silver-gray to facilitate solar reflection and reduce radiant heat. China's self-made insulation trucks have two categories: refrigerator insulation vehicles and mechanical insulation vehicles.
Real Time fluorescence quantitative PCR system is a variation of the standard PCR technique that is commonly used to
Using sequence-specific primers, the number of copies of a particular DNA or RNA sequence can be determined.
By measuring the amount of amplified product at each stage during the PCR cycle, quantification is possible.
