The invention discloses a multiple NaI (T1) detectors based radioactive substance two-dimensional locating method in an access control detection system. A two-dimensional locating model of a radioactive substance is determined through the measurement of the attenuation law of gamma rays and the change of the azimuth angle of the radioactive substance at different positions relative to a detector. The energy resolution capability of the NaI detector is utilized to recognize the radioactive nuclide, and the problems of mutual interference of different radioactive nuclides and simultaneous location of different radioactive substances can be effectively solved under a multi-source condition. According to the method, a maximum characteristic peak counting detector with high counting capability, a detector at the opposite side and a second largest characteristic peak counting detector at the opposite side are adopted, situations that the location error is increased and even a position close to the edge cannot be located due to the influence of statistical fluctuation on the counting value of the detector when the solid angle of the radioactive substance on the detection surface of the detector is too small or the attenuation distance is overlong are avoided, and the method has the advantages of short measurement time, high location accuracy and the like.

The invention discloses an electrochemical biosensor based on triplex catenated DNA (deoxyribonucleic acid) and a preparation method. An inner ring probe and an outer ring probe are designed; the twoprobes complement each other to form DNA ringlets; the ringlets are self-assembled through Hoogsteen bonds and Watson-Crick bonds under an appropriate pH (potential of hydrogen) condition to form a catenated nucleic acid chain; a catenated DNA long chain is connected onto a gold electrode with the assistance of an acquisition probe and a connecting probe; hexaammineruthenium is absorbed on a DNA framework by an electrostatic effect; and miRNA (micro ribonucleic acid) is detected by detecting an electrochemical signal of hexaammineruthenium. The biosensor accurately detects target miRNA-21 between 1fM and 10nM, and a limit of detection is 1.63fM. The biosensor can directly detect miRNA in a serum sample without pretreatment, can be used for detecting other biomarkers, and has good application prospects in clinical diagnosis and prognosis.

The present invention relates to a system and a method for family gateway service identification which are realized on the basis of a strategy. The identification information of a family terminal is certified by an automatic configuration server, and the identification information of the terminal is reported to the automatic configuration server. After accomplishing certification, the automatic configuration server inquires the service information of the terminal from a service application system by using the identification information of the terminal, and then makes a request for obtaining astrategy matched with the service from a strategy server by using the terminal service information obtained. The terminal service flow strategy obtained by the automatic configuration server from thestrategy server is sent to the family gateway. The family gateway realizes the identification and the control to the service flow through the identification information and the control method contained in the strategy. The system and the method of the present invention have the advantages that the service flow identification is accurate, the realization is simple, the operation is nimble, and thesystem and the method are easy for deployment and implementation.
