The invention discloses a Chinese electronic medical record named entity extraction method and system. The method comprises the following steps: mapping each word in an input statement into a vector through a character embedding layer; inputting the character sequence by adopting an LSTM model to obtain an implicit representation vector; taking each word as the last word of the semantic unit withthe word as the end, and carrying out semantic segmentation to obtain all grid codes corresponding to the word; carrying out linear combination on all grid codes of each character to obtain a final vector of each character, wherein a weight in the linear combination is given by a self-attention mechanism; taking a deep residual network as an output decoding layer to decode a named entity chain. According to the Chinese electronic medical record named entity extraction method and system, various medical named entities can be automatically extracted from the Chinese electronic medical record, the extraction efficiency is improved, and the labor consumption in a medical record structuralization process is avoided.

The invention relates to a large-thickness blunt-trailing-edge wind turbine blade. At least one large-thickness blunt-trailing-edge standard airfoil with a relative thickness which is larger than 40% is adopted in a blade transition section (20) connecting a circular section (1) of a blade root and the largest-chord-length section (2) of the blade. Meanwhile, a blade pneumatic appearance optimization design technique is adopted, so that the distribution range of blade sections of the airfoil with a relative thickness which is larger than 30% in the spreading direction accounts for at least 35% of the position ratio from the blade root to the section spreading direction. Smooth transition is carried out on trailing edges of sections around the large-thickness blunt-trailing-edge standard airfoil in a certain trailing-edge thickness transition mode so that all of or a part of the trailing edges of the blade are blunt trailing edges.
