The method of preparing chicken extract flavour liquidThe invention relates to a method of preparing pure natural chicken extract flavour liquid and the flavour liquid prepared by utilizing the same. The method of preparing chicken extract flavour liquidcomprises the steps of taking chicken skeleton with low price as the raw material, curing and fermenting the chicken skeleton with curing agent at low temperature, distilling the body fluid of the fr comprises the steps of taking chicken skeleton with low price as the raw material, curing and fermenting the chicken skeleton with curing agent at low temperature, distilling the body fluid of the fresh chicken in a water-resisting mode under the condition of pressure distillation to obtain distillate, removing the grease on the upper layer of the distillate by cooling, filtering the distillate tesh chicken in a water-resisting mode under the condition of pressure distillation to obtain distillate, removing the grease on the upper layer of the distillate by cooling, filtering the distillate to obtain transparent clear extraction, and heating and sterilizing the transparent clear extraction to obtain the chicken extract flavour liquid. The preparation process of the chicken extract flavouro obtain transparent clear extraction, and heating and sterilizing the transparent clear extraction to obtain the chicken extract flavour liquid. The preparation process of the chicken extract flavourliquid provided by the invention is unique and is easy to realize and more reasonably and effectively extracts the natural chicken flavour components. The obtained chicken extract flavour liquid is r liquid provided by the invention is unique and is easy to realize and more reasonably and effectively extracts the natural chicken flavour components. The obtained chicken extract flavour liquid is rich of a great deal of amino acid and peptide components, contains no food additive, is transparent and has delicious taste and abundant nutrition.ich of a great deal of amino acid and peptide components, contains no food additive, is transparent and has delicious taste and abundant nutrition.

The invention discloses a method for partial reference evaluation of wireless videos based on space-time domain feature extraction, which relates to a method for evaluating video quality. On the basis of performing profound understanding and detailed analysis on the existing video objective quality evaluation model, by combining visual characteristics of human eyes, the invention provides the method for the partial reference evaluation of the wireless videos based on the space-time domain feature extraction to improve the conventional SSIM model. The method takes the fluency of the time domain and the structural similarity and the definition of the space domain of the videos as main evaluation indexes, and under the condition of ensuring the evaluation accuracy, the method extracts characteristic parameters of ST domains (the space domain and the time domain), establishes a new evaluation model, reduces the reference data needed by the evaluation and lowers the computational complexity to ensure that the evaluation model is suitable for evaluating the quality of wireless transmission videos in real time.

The effective total alkaloid extract of stemonaceae stemona sessilifolia has the activity of relieving and / or inhibiting cough.

The invention relates to a heat supply system for directly recovering sewage multi-section flashing steam waste heat by using multiple sections of absorption heat pumps, which is used for recovering sewage flashing steam waste heat. The system comprises 1, 2, ..., and N independent sealing chambers and the multiple sections of absorption heat pumps, wherein the multiple sections of absorption heat pumps comprise respective 1, 2, ..., and N generators, 1, 2, ..., and N condensers, 1, 2, ..., and N absorbers and 1, 2, ..., and N evaporators; water steam which is formed by flashing sewage in the1, 2, ..., and N independent sealing chambers and has different pressure from high pressure to low pressure enters 1, 2, ..., and N evaporator tubes sequentially by 1, 2, ..., and N flashing steam and is directly connected with the 1, 2, ..., and N evaporators of the multiple sections of absorption heat pumps; and flashing steam condensate outflows the 1, 2, ..., and N evaporator tubes and reflows to respective 1, 2, ..., and N liquid phase areas of the 1, 2, ..., and N independent sealing chambers sequentially by respective 1, 2, ..., and N flashing steam condensate. The system can reduce heat loss, improve the water-supply temperature of hot water and reduce investment and running cost.

The invention discloses a method for identifying the authenticity of purple sand teapot bottom style, which comprises the following steps: zooming the purple sand teapot bottom style image, extractingthe key points of purple sand teapot bottom style image under different scale spaces; scaling the purple sand teapot bottom style image; from the extracted key points, a number of key points existingin different scales being selected as stable points adaptively; calculating the matching ratio of the stable points of the two bottoms of the purple sand teapot, and judging the similarity of the twobottoms of the purple sand teapot according to the matching ratio, so as to judge the authenticity of the purple sand teapot.

The invention discloses an underwater target recognition method based on light vision, which comprises the following steps: collecting underwater target object images under natural light and artificial light source environments respectively through an underwater image collection system; Enhancement, noise location, denoising and color shift correction; sequentially extract the shape feature, color feature and texture feature of the target; the obtained shape feature matrix, color feature matrix and texture feature matrix form a training sample set, and then carry out target training, and the natural The test samples under the illumination and artificial light are classified, and the classification results are output. The invention can reliably identify underwater targets.

The invention discloses a method for identifying the authenticity of an inscription on the bottom of a purple clay teapot, which comprises the following steps: scaling an image of an inscription on the bottom of a purple clay teapot, extracting key points of the inscription on the bottom of a purple clay teapot in different scale spaces; from the extracted key points, self-adaptive A number of key points that exist in different scale spaces are accurately selected as stable points; the matching rate of the stable points of the two images of the bottom of the purple clay teapot is calculated, and the similarity of the two images of the bottom of the purple clay teapot is judged according to the matching rate, so that To judge the authenticity of Zisha teapot.
