Disclosed are a method and system for detecting a complex multi-step attack in an electric power system. The method includes: collecting interaction behavior data of a network entity; preprocessing the interaction behavior data of the network entity based on a heterogeneous graph to obtain input data; and inputting the input data into a complex multi-step attack detection module to obtain an attack detection result. Information is extracted from the interaction behavior data to construct a node and an edge of the heterogeneous graph. Timestamp information of a destination node and an adjacent source node of the destination node is input into a Time2Vec layer to obtain a first time embedding representation. Data that fuses node feature information and the first time embedding representation is input into a Heteformer layer, and a second node embedding representation is obtained as input data and input into the complex multi-step attack detection module.

A multi-directional radiation leaky coaxial cable, including an inner conductor, an insulating layer, an outer conductor and a sheath which are sequentially and coaxially nested from inside to outside. The outer conductor is provided with at least two rows of slotted hole groups, the at least two rows of slotted hole groups are distributed at different angles in a circumferential direction of the outer conductor, and each row of slotted hole group includes a plurality of slotted hole arrays which are periodically arranged along an axial direction of the outer conductor. Each slotted hole array includes a plurality of slotted holes, pitches of the slotted hole groups are the same, and a periodic arrangement difference of two adjacent rows of slotted hole groups in the circumferential direction is half a pitch, such that a phase difference of respective excitation electric fields is 180°.

The present invention designs and synthesizes the ascorbyl ester derivatives of the aryl (ethanoic) propanoic acid non-steroidal anti-inflammatory medicaments, such as ibuprofen, ketoprofen and naproxen, and addition salt of the derivatives with pharmaceutical acid or pharmaceutical alkaline. The non-steroidal anti-inflammatory medicament which takes the ibuprofen as the representative is a common antipyretic analgesic medicament. The invention has remarkable antipyretic and analgesic effects and good safety except for anti-inflammatory effect, thus being not only suitable for adults, but also suitable for the elderly people, infants and children. The aryl (ethanoic) propanoic acid ascorbyl ester can be converted into ascorbyl ester derivatives and the addition salts of the derivatives with pharmaceutical acid or pharmaceutical alkaline, which can improve the water solubility thereof, facilitate intravenously administration, reduce the onset time, improve the bioavailability, reduce the stimulation effect to gastrointestinal tract, and enhance the penetrating capacity to hemato encephalic barrier, and can be used as a novel medicament to be applied for antiphlogistic, antipyresis, analgesia, treatment of arthritis, dysmenorrheal, multiple sclerosis, pneumonia cystic fibrosis and patent ductus arteriosus of premature infants, and prevention and treatment of cerebral apoplexy, hypoxic-ischemic brain damage, senile dementia and certain cancers.
