The invention discloses a fast detection method of SAR (Synthetic Aperture Radar) image targets under strong sea clutter. The method comprises: S1, adopting a regional block dividing strategy to divide a large-scene SAR image into a plurality of sub-block SAR images; S2, acquiring target-clutter contrast-enhanced sub-block coherence images, which correspond to the sub-block SAR images, on the basis of sub-aperture coherence processing; S3. screening out target sub-block coherence images containing the targets and corresponding target sub-block SAR images on the basis of significance of the sub-block coherence images, and using the same as candidate target sub-block images; S4, carrying out fine target detection on the candidate target sub-block images, wherein fine target detection includes detecting low-scattering target pixels for the target sub-block coherence images, detecting target detail contours for the target sub-block SAR images, and fusing two detection results; and S5, removing false alarms for a fine target detection result, and carrying out regional merging to obtain a final target detection result. According to the method, the targets which are in the sea-surface large-scene SAR image and of complex structures and low scattering intensity can be detected, a detection rate is high, a false-alarm rate is low, self-adaptability is high, and a calculation speed is fast.

The invention generally relates to anesthetic compositions comprising low doses of a selective a-2 adrenergic receptor agonists in combination with anesthetic agents. The invention also relates to methods of using these compositions; in particular, the use of these compositions in humans to enhance the efficacy of a local peripheral anesthetic injection. The compositions and the methods are particularly useful in regional block anesthetic injections, and more particularly, in dental anesthetic injections.

The invention provides a manufacturing method for forming a conductor line on a non-conductive substrate. The manufacturing method comprises the following steps that: A, a non-conductive substrate is selected; B, a printing ink layer is formed on the surface of the non-conductive substrate; C, laser engraving is performed on the printing ink layer and the surface of the non-conductive substrate through laser, and the laser is utilized to divide the printing ink layer into a plurality of continuous or non-continuous different regional blocks, and then, printing ink layer segments of the non-continuous regional blocks are removed through gasification such that portions of the non-conductive substrate where the non-continuous regional blocks are located are revealed; D, metallization processing is performed on the surfaces of the revealed portions of the non-conductive substrate such that the conductor line which is composed of a metal coating can be formed: D, remaining printing ink layer segments are removed, and the conductor line is formed on the non-conductive substrate.

The invention relates to a medium voltage distribution network planning method for an electric power system, and particularly relates to a unitization system medium voltage distribution network planning method based on a load correlation coefficient. The unitization system medium voltage distribution network planning method comprises the following steps: 1, data collection and acquisition of daily load characteristic, quarter load characteristics and annual load characteristics of different users are performed based on an electric energy mass online monitoring system, and user archival information is established; 2, a government department links and collects documents and masters planning construction property and scale of each regional block of a city; and 3, oriented by power utilization requirement (based on urban control and regulation) of land blocks, a comprehensive typical load prediction model is established. By adoption of the technical scheme, the problems of low load rate, high construction investment, difficulty in land applying, and the like caused by insufficient power utilization requirement classification and analysis and the fact that the load development requirement is satisfied by only increasing system capacity existing in the prior art are solved; the power grid equipment utilization rate and power grid economic benefit can be greatly improved; and reference basis is provided for the power grid investment and construction.

The memory includes a substrate and following structure. Common doping trap of first conduction type storage unit is formed on the substrate. Insulated each other multiple second conduction type embedded bit lines is formed on common doping trap of the storage unit. Multiple storage regional blocks arranged in series are formed on single line in multiple embedded bit lines. Each multiple storage regional block contains at least one piece of storage transistor, which includes stacked grid electrodes, source electrode and drain electrode. Being parallel spanned above multiple storage regional blocks in series, the regional bit line through contact plug is contacted to drain electrode electrically. Moreover, electrical short circuit is formed between the contact plug and inferior embedded bit line. The invention has low power expenditure and compatible operation mode. Thus, high-speed program flash memory and high-density data flash memory can be integrated in single chip.

The embodiment of the invention provides a license authentication method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining an authentication instruction input by an authentication user, wherein the authentication instruction comprises a copy license, an identifier of an original license and an authentication type, and the authentication type comprises content authentication and file authentication; Determining an original certificate and an authentication type according to the authentication instruction; When the authentication type is contentauthentication, determining first authentication information in a copy certificate corresponding to the content authentication; When it is judged that the authentication user is allowed to check theoriginal certificate corresponding to the identifier of the original certificate, determining first authentication information of the original certificate corresponding to the content authentication in the regional block chain network by utilizing a preset smart contract; Comparing whether the first authentication information in the copy certificate is consistent with the first authentication information in the original certificate or not; And if yes, determining that the copy certificate and the original certificate are certificates with the same content. According to the invention, the certificate is authenticated according to the authentication instruction of the authentication user.
