Abstract: Embodiments of the application disclose a heating control method, device and apparatus. The device is internally provided with a first heating tube and a second heating tube, and a cooking cavity between the first heating tube and the second heating tube is configured to place to-be-heated food. When time reaches a switching time point, a magnitude relationship between heating temperatures of the first heating tube and the second heating tube is switched, so that the effect of turning the food can be achieved to enable the food to be heated uniformly, and prevent a situation in which the food is undercooked or burnt.

Abstract: The present invention relates to computer science, molecular biology and microfluidics technique which provides a DNA molecular computer based on microfluidic chip. The objective is to provide a DNA molecular computer which uses the microfluidic chip as a operation platform, mainly including: using DNA molecules as operation media, using the microfluidic chip as the operation platform of a DNA molecular operator; using DNA molecules as storage media, using the microfluidic chip as the operation platform of a DNA molecular storage; using a electronic computer and a detector as the kernel of a controller; said microfluidic chip includes a DNA molecular computation region and a DNA molecular storage region. The microfluidic chip consists of digestion, ligation, PCR amplification and chip electrophoresis unit connected by microchannels in turn, and carries out the liquid control through micropumps and microvalves.
