Abstract: An electric heater, and an apparatus, a heating and air conditioning system and a vehicle, each comprising the electric heater, are provided. The electric heater comprises an outer frame; a heating core configured to connect to a power source and disposed within the outer frame; and a sealing-waterproof glue member disposed within the outer frame and configured to encase at least one end of the heating core. The heating core further comprises: a plurality of heat dissipating components and heating components arranged alternately, and each of the heat dissipating component is coupled with a heating component via a thermal conductor. Each of the heating components further comprises a core tube and a positive temperature coefficient thermistor disposed in the core tube.

Abstract: This invention relates to methods for constitution and production of colony varieties of crops. Its characteristics are shown below. According to their phenotypes, single-genotype varieties, hybrid combinations or mixtures of varieties and combinations from fundamental populations, which are consistent or uniform in major characters and share particular breeding goals, will constitute the colony varieties of crops. The said single-genotype varieties or hybrid combinations are multiplied separately. According to the breeding goals, their seeds are mixed in a specific ratio to form the preparations for planting. The varieties produced in such a way are featured with uniformity, stability and peculiarity.
