The invention provides a refrigerant leakage detection method and an air conditioner. The refrigerant leakage detection method includes the following steps: S1: the air conditioner is running, and a first-level judgment is performed to determine whether the first-level judgment condition is satisfied; Refrigerant leakage; if not, go to step S2; S2: Execute secondary judgment to determine whether the secondary judgment condition is met; if yes, refrigerant leakage occurs; if not, go to step S3; S3: Judgment whether the preset detection trigger is met Conditions; if yes, execute step S1; if no, re-execute step S3; the detection side of the refrigerant leakage described in the present invention can improve the effectiveness of refrigerant detection and enhance the safety of the entire air-conditioning system; that is, the method can achieve Comprehensive benefits of accurate judgment, energy saving and safety.

The invention discloses a software protection method based on network, a client side and a server, which is used for improving the accuracy and the effectiveness for detecting whether client side software is distorted. The method comprises: a server side receives a program operation request sent by the client side and sends random data to the client side according to the program operation request; the client side adopts a set Hash algorithm to determine a first Hash value according to client side identification, random data and a program code segment which is stored in the client side and corresponds to the edition information of software to be operated; the server side adopts the set Hash algorithm to determine a second Hash value according to client side identification, random data and a program code segment which is stored in the client side and corresponds to the edition information of software to be operated; the first Hash value and the second Hash value are compared to determine whether the client side is permitted to execute the program according to the comparison result. The technical scheme of the invention improves the accuracy and the effectiveness for detecting whether client side software is distorted.

The invention discloses a human epididymis protein immune detection kit and its use method. Its active ingredients include labeled immune gold nanoparticle reagent and Fe3O4@Au immune nanoparticle reagent with a volume ratio of 1:1. Surface-enhanced Raman spectroscopy and core-shell magnetic materials. After activation of carboxyl groups on the surface of gold nanoparticles, inject human epididymis protein antibody to obtain labeled immune gold nanoparticle reagent; after amination modification on the surface of Fe3O4, mix with gold nanoparticles, inject human epididymis protein antibody, and obtain a reagent with good magnetic properties and Fe3O4@Au immune nanoparticle reagent with excellent SERS enhanced activity. The kit provided by the invention has mild conditions for use, and portable detection instruments can be used without large-scale equipment; the detection limit of human epididymis protein can reach femtogram levels, and has high sensitivity; the base of the kit has a recyclable characteristics, reducing the cost of testing.

The invention provides a natural light interference resistant intelligent gas meter. One surface of a sampling plate provided with components and parts is toward to a sampling character wheel, and adistance between a photoelectric detector on the sampling plate and the circumference of a sampling character wheel is not more than 1mm; the sampling character wheel is provided with numbers and a reflecting surface, the numbers comprise reference numbers and general numbers, and the reference numbers are arranged above and below the reflecting surface; the heights of the reference numbers are slightly lower than that of the general numbers. The invention further provides a gas sampling and detecting method, which comprises a light protecting and detecting step, a sampling step and a standby step. According to the gas meter provided by the invention, and the distance between the sampling plate and the sampling character wheel can be controlled and the proper color of the sampling character wheel can be selected, so that the incident dose of outside light rays can be reduced, the emission current of an optoelectronic switch tube can be reduced, and the reliability of the intelligent gas meter can be improved; furthermore, according to the gas detecting method provided by the invention, the effectiveness of the detection can be ensured by the light protecting and detecting step, and the low energy consumption of the operation can be realized by the standby step.
