The invention discloses a method for obtaining transgenic cotton by transforming live immature embryos mediated by Agrobacterium, which consists of the steps of peeling off aseptic embryos, preparing transformation liquid, shaking and infecting, preparing transgenic cotton, and identifying transgenic plants. In the aseptic embryo stripping, 30% hydrogen peroxide and sterile water are prepared into a disinfectant solution, the cotton seeds are plucked and put into the disinfectant solution, soaked at 25°C for 24 hours, the seeds are taken out and placed in a petri dish, and the seed coat and 1 / 3 to 1 / 2 cotyledons, and the remaining cotton embryos are placed in a petri dish containing basal medium to injure the cotton embryos; in the step of preparing the transformation solution, the induction solution is made of acetosyringone and magnesium sulfate, and acetosyringone Ketones can induce the activation of the Vir gene of Agrobacterium and improve the efficiency of exogenous gene integration; in the shaking infection step, Silwet L‑77 and MS liquid medium were added to the transformation solution to make Agrobacterium cover cotton embryos in a wider range. The invention has the advantages of easy screening, short cotton growth cycle, easy operation, transformation efficiency and the like.

The invention relates to an electrode assembly, a lithium-oxygen thin-film battery and a preparation method thereof. The electrode assembly comprises an insulating substrate, a positive electrode filmlayer, a negative electrode film layer and a protective layer. The positive electrode film layer and the negative electrode film layer are located on the same surface of the insulating substrate, a space is between the positive electrode film layer and the negative electrode film layer, and the protective layer is located on the upper surface of the negative electrode film layer. The electrode assembly has a simple structure, provides a reliable platform for in-situ characterization, and has the advantages of large size adjustable range, high material utilization, and simple and rapid preparation method. The lithium-oxide thin-film battery prepared from the electrode assembly facilitates integrated design and battery portable processing.

The invention relates to the technical field of dairy products, and discloses a method for screening flavored milk powder formulas. The method of the present invention simulates the production process to design the rapid viscosity analyzer (RVA) measuring program of the common modulated milk powder formula, and tests the viscosity change of the common modulated milk powder feed liquid in the simulated production heating process; simultaneously monitors the actual production with the same formula product The viscosity of the thick milk before spraying at the control point was compared, and the consistency of the viscosity data confirmed that the method was feasible, so as to determine the RVA measurement procedure of the flavored milk powder, and then screen the flavored milk powder formula according to the characteristic value of the viscosity curve. The method of the invention is easy to operate, and the characteristic value of the viscosity curve is clear. As the basis for judging the flavored milk powder formula, it is concise and clear, easy to judge, and can quickly screen the formula. And it effectively reduces the impact caused by the deviation of production experience, reduces the unfavorable loss caused by trial production, and reduces the cost and time of research and development of new flavored milk powder.

The invention provides a method and device for identifying electronic manuscripts. The trigger circuit makes the nib heat, so that the temperature of the nib is significantly higher than the ambient temperature; when the nib touches an object, the effective contact information is sent to the infrared camera through wireless transmission; The infrared video image is sent to the recognition processing circuit to correct the infrared video image in turn and record the position of the pen tip in each frame of the infrared video image after correction, and then convert it into two-dimensional coordinates for recording; complete the contact at the pen tip Afterwards, the infrared camera stops shooting, and the recognition processing circuit linearly connects the nib coordinate points of all image frames in this contact process according to the sequence of image acquisition to form a manuscript handwriting image and stores it, and simultaneously performs text recognition processing and caches it. The invention can combine the image character recognition technology and the writing tool to record the original manuscript and transform the electronic characters while writing.

The application discloses an information correction method, device, electronic equipment and storage medium, and relates to speech recognition technology. The specific implementation plan is: obtain the speech recognition result matching the interactive speech currently input by the user, and perform entity recognition in the speech recognition result to obtain entity feature information; according to the latest acquired historical speech recognition result, and the speech As a result of the recognition, contextual information is generated; according to the contextual information and the entity feature information, clarification and correction information matching the historical speech recognition results is obtained. The embodiment of the present application realizes that only by inputting the voice, the word or word that was incorrectly recognized in the last historical voice recognition result due to a slip of the tongue or homonym problems can be modified, which avoids the user's manual input and modification, improves the modification efficiency, and makes the voice interaction process more natural.
