The invention discloses a maximum wind energy capturing method for a double-feed type wind generating set in the field of wind power generation. A BP neural network model with the air speed value, the air direction value and the wind wheel rotating speed value as the input quantity and the electromagnetic torque value as the output quantity is constructed, the expected theoretical optimal air wheel rotating speed value is calculated according to a tip speed ratio point formula, the expected theoretical optimal air wheel rotating speed value is substituted into the BP neural network model to determine the initial control quantity of the electromagnetic torque value initial control quantity, a step-length-changing climbing search method is adopted, the changed step length of the electromagnetic torque value is reduced along with rising of the control period number, the electromagnetic torque value is changed in a small range so that the maximum power value point can be found, the real-time generator rotating speed value is measured in real time before each time of search, when the changed value of the generator rotating speed value exceeds the limiting value compared with the initial generator rotating speed value generated when the whole search is started, the search is started again, and when the absolute value of the difference value of the generator rotating speed values or the power generating power values in two adjacent control periods is smaller than the limiting value, the search is over. The maximum wind energy capturing method has the advantages that overlong periods or oscillation is avoided in the climbing search, and the maximum power capturing is ensured.

Implementation method of ADS-B information security transmission: (1) Construct a three-level vertical management system according to the air traffic control center, flight information region, and the control area to which the flight information center belongs. The lowest layer is the ADS- User B, ADS-B users and their control area servers communicate with each other using an independent two-way authentication mode; (2) ADS-B users are at the beginning of the planned route safety period, and the air traffic control center assigns a temporary ADS-B user to the ADS-B user Identity, and establish a mapping relationship from temporary identity to real identity, and send the mapping relationship to the management department of the flight information region that the ADS-B user plans to pass through; before the ADS-B user takes off, the management department of the control area will The user's temporary identity in the server, the two-factor symmetric key, and the server identification code of the ground server near the user's planned route and the public key information of the server message authentication code are secretly distributed to the ADS-B user. The invention can effectively resist various active attacks, realize safety authentication, and ensure the safety of ADS-B information transmission.

The invention discloses a sexual development abnormality-related gene capture kit and application thereof. The sexual developmental abnormality-related gene capture kit provided by the present invention is to perform target region sequencing on the whole exome or sexual developmental abnormality-related genome (accounting for 1% and 0.01% of the whole genome respectively) of patients with hereditary sexual developmental abnormality Analysis, which captures most of the pathogenic mutation information of the disease, has the advantages of small sample size, low cost, and high throughput, and can detect more samples, which promotes the identification of new pathogenic mutations of genetic abnormalities. Find. The genetic mutation sites related to abnormal sexual development selected in the present invention cover common hotspot mutations and other uncommon mutation points in Chinese. The high-throughput of the kit can comprehensively screen the genes related to abnormal sexual development in the population, which is of great significance for improving the quality of the population and benefiting the society.
