The invention relates to an ice temperature gas conditioning and coupling compound antioxidant multiple-factor fence preservation technology of cooked beef, belonging to the technical field of meat preservation. The method comprises the steps of soaking the beef into a mixed solution containing 0.25-0.75% of tert-butyl hydroquinone (TBHQ), 10.75-20.75mg/ L of tea polyphenol and a flavoring agent, cooking thoroughly, cooling and then putting the cooked beef into a food preservation box; vacuumizing, and charging 60-80% of oxygen, 10-30% of nitrogen and 10% of CO2; sealing the box by using a high-barrier compound packaging film which is made of polyethylene terephthalate (PET)/ chlorinated polypropylene (CPP) material and has the thickness of 0.062mm, and preserving at the temperature of 0-1 DEG C. Therefore, the aims of good preservation effect, low cost, good flavor and long preservation time are achieved.

The invention discloses a new energy vehicle energy storage optimization control method based on a multi-objective genetic algorithm, which comprises the following steps: establishing a control strategy database of the vehicle-mounted energy storage system; establishing characteristic data module of vehicle energy storage system; establishing the evaluation module of multi-factor coupled energy storage system to evaluate the advantages and disadvantages of the current control strategy in the whole life cycle; a multi-objective genetic algorithm is used to optimize the energy-saving control strategies. By comparing and analyzing the effect of each control strategy, the optimal control strategy of new energy vehicle energy storage is obtained under the coupling of multiple factors. Under thecondition that the passenger comfort degree is ensured, the speed command designed by the invention can realize traction energy saving. The speed command obtained from the final design meets the requirements of non-dominated standards, which is very beneficial to the decision-making based on the time uniform distribution standard and the energy consumption sensitivity standard. Aiming at the energy-saving optimization of speed commands under various control strategies of energy storage system, the optimal control strategy of vehicle-mounted energy storage system can be obtained through the comparative analysis of its effects.
