Reverse authentication method and system of terminal equipment based on authority body

The invention discloses a reverse authentication method and system of terminal equipment based on an authority body. The reverse authentication method comprises the steps that a user reads and encrypts a plain code identifier of the terminal equipment by employing a mobile client, and transmits the identifier to an authority body authentication platform; the authentication platform decrypts the plain code identifier and checks the identifier with platform registration information, generates a random checking code if the information is consistent, encrypts the code and transmits the code to the mobile client and the terminal equipment; the terminal equipment decrypts the random checking code and displays the code on the terminal equipment in a plaintext mode; the mobile client decrypts the random checking code, the user compares to determine whether the checking code in the mobile client is consistent with the checking code on the terminal equipment or not, the terminal equipment is safe and legal if the checking codes are consistent, or otherwise, the terminal equipment is fake. According to the method and the system, self-authentication of the terminal equipment is avoided, the authentication is directly carried out on the terminal equipment in the authority body authentication platform through the mobile client, the safety and reality of the terminal equipment are ensured, and the risk and direct property loss resulting from cheating personal information by the fake terminal equipment can be avoided.

Large horizontal ammonium nitrate solution storage tank

PendingCN112173462ALow conveying head requirementLow head requirementLarge containersTank wagonsAmmonium nitrateMechanical engineering
The invention relates to a large horizontal ammonium nitrate solution storage tank which comprises a tank body, a feeding port, a discharging port, a heating mechanism and a drenching mechanism. The feeding port, the discharging port, the heating mechanism and the drenching mechanism are arranged on the tank body, a backflow circulation mechanism is further arranged in the tank body, and the backflow circulation mechanism is composed of a plurality of backflow circulation assemblies arranged in the height direction of the tank body. Each group of backflow circulation assembly consists of two backflow circulating pipes which are arranged at opposite angles in the axial direction of the tank body, one end of each backflow circulating pipe extends out of the tank body and is connected with anexternal backflow pipeline, and the backflow pipelines are also connected with the feeding port and are used for circulating parts of materials discharged from the discharging port into the tank bodythrough the backflow circulating pipes; and outlets of the two backflow circulating pipes in the same group of backflow circulation assembly are not on the same straight line. Compared with the priorart, the large horizontal ammonium nitrate solution storage tank has the advantages that the concentration uniformity of a solution in the tank can be improved, operation is safe and reliable, and the overhaul rate is low.

Method for long term storage of grain without deterioration and equipment thereof

InactiveCN101485356BLong shelf lifeThe solution will not deteriorateSeed preservation by dryingGrain storageNitrogen
The invention relates to a method for prolonging storage tenure of grains and bean grains to prevent deterioration, and equipment thereof. The equipment comprises a grain store, wherein the grain store can ensure vacuum degree and can be sealed; a vacuum pump assembly is arranged outside and communicated with the grain store; a pipeline and a valve are arranged on the store wall to fill nitrogen into the grain store; the store wall is provided with an entry inspection door; an air lock store is arranged on a cover board of the entry inspection door, is communicated with the grain store through an air lock valve and the outside through a sampling valve; a discharge valve, a discharge pipeline and a conveying pipeline with a turnover valve are arranged in the center of the bottom of the store; and an electroheat low-temperature drying system, a temperature sensor and a humidity sensor are arranged in the grain store, and the temperature sensor and the humidity sensor can detect temperature and humidity in the grain store respectively, so that oxygen and humidity during the period of grain storage can be controlled by the vacuum technology, and the grains are enforced to be in natural dormancy. Therefore, speed of natural exhaustion of the grains can be controlled to achieve the aim of prolonging the tenure of storage of the grains to prevent deterioration, and the grain store has low cost, easy construction and wide application range.

Method for promoting anthesis of Indica sterile line

The invention discloses a method for promoting anthesis of an Indica sterile line. The method comprises the following steps: selecting single strains which are in a full heading stage and have neat layers of ears of rice in the sterile line in an afternoon of a day before the day when test crossing and transformation are carried out, cutting out old and excessively young ears of rice in the single strains of the sterile line, retaining flag leaves of the ears of rice, stripping the flag leaves down to ear necks, cutting out bloomed glumous flowers at upper parts of the ears of rice and glumous flowers with whitening glumous hulls at the basal parts of the ears of rice, carrying out watering and moisture retention after trimming and standing the single strains of the sterile line for subsequent usage; and in the day of test crossing and transformation, treating the sterile line in lukewarm water with a temperature of 44 to 46 DEG C, then wrapping the ears of rice of the sterile line with a wet agricultural black mulch film immediately, placing the wrapped ears of rice in sunlight for treatment for 20 to 30 min, opening the wrapping mulch film, flicking off unnecessary moisture and anther, covering the ears of rice with a waterproof hybridization paper bag, enclosing the paper bag and carrying out further test crossing and transformation. With a technical scheme in the invention, anthesis of the sterile line is promoted, an outcrossing rate is increased, seed quality is improved and the seedling rate of a coeno-species is enhanced.
