The invention discloses a method capable of preventing browning of stem segments of litsea coreana in tissue culture and a culture medium thereof, and belongs to the technical field of tissue culture.The culture medium contains an MS basic culture medium, 8 mg / L riboflavin, 2 mg / L of 6-BA, 0.1 mg / L of NAA, 30 mg / L of sucrose, and 6.5 mg / L of agar. The method capable of preventing browning of thestem segments of the litsea coreana in the tissue culture includes the steps of explant treatment, explant disinfection, and browning-preventing culture, and can be adopted to effectively reduce the browning rate of the stem segments of the litsea coreana in the tissue culture and increase the proliferation coefficient.

Embodiments of the present invention provide a control method for starting a compressor of an air conditioner and an air conditioner. The control method for starting the compressor of the air conditioner includes: obtaining a start-up command; if there is a start-up command, detecting the system high pressure P d and system low pressure P s ; Determine the pressure ratio P when the air conditioner compressor starts, and set the compressor initial starting current according to the pressure ratio P; wherein, the pressure ratio P=P d / P s . The invention achieves the technical effect of improving the start-up success rate of the air conditioner compressor.

The invention relates to an application starting method and device, computer equipment and a storage medium, and belongs to the technical field of computers. The method includes: acquiring a first view of a to-be-hanged-on game when running of the to-be-hanged-on game is detected; adding a second view in the first view, wherein the second view includes at least a script file of the to-be-hanged-ongame; and running the script file of the to-be-hanged-on game in the to-be-hanged-on game to complete application starting. According to the method, when running of the to-be-hanged-on game is detected, the second view including the script file of the to-be-hanged-on game is added in the first view of the to-be-hanged-on game, and the script file of the to-be-hanged-on game is run in the to-be-hanged-on game to complete application starting, and mounting a hanging-on application of a suspension-window form in the game is enabled to be unnecessary; and in addition, a terminal does not need toauthorize a hanging-on application, a starting process of the hanging-on application is simplified, a starting cycle of the hanging-on application is shortened, a starting rate of the hanging-on application is increased, and promotion for the hanging-on application is realized.

The invention relates to a method for simultaneously improving the strength and plasticity of low-carbon low-alloy steel, belonging to the technical field of metal materials. According to the method, a quenched low-alloy steel containing Mo and containing more than one of V, Nb and Ti is sequentially subjected to tempering treatment, dynamic large deformation and annealing treatment to obtain a low-carbon low-carbon steel with high strength and high plasticity at the same time. Low-alloy steel. The carbides precipitated in the tempered low-carbon low-alloy steel containing strong carbide-forming elements can further refine the grains during the dynamic large deformation process, and the large amount of fine dispersed carbides in the subsequent annealing process provides significant The strengthening effect of the second phase is also beneficial to the improvement of steel plasticity.

The invention provides a draught fan starting method and system, computer equipment, a readable storage medium and a refrigerator. The draught fan starting method is used for the refrigerator and comprises the steps that after a starting instruction is received, the temperature of an environment where the state of the refrigerator changes from deenergization to energization and the temperature inside the refrigerator are determined; according to the environment temperature, at least one refrigerator temperature interval is determined; according to the temperature inside the refrigerator and the refrigerator temperature interval, delay time of a draught fan in the refrigerator is determined; the draught fan is started delay time after the starting instruction is received. By means of the technical scheme, starting of the draught fan is delayed after the starting instruction is received, so that loads of the refrigerator are effectively reduced; especially under a bad condition that theenvironment temperature is too high and the voltage is too low, the probability that the refrigerator is normally started is improved, and normal refrigeration can be conducted after the refrigeratoris started, so that the reliability of running of the refrigerator in different environments is further improved, and the environmental suitability is higher.
