Abstract:
A method for fault location to multi-terminal traveling wave in a direct current distribution line, which belongs to the field of power line fault ranging and location technology. The method includes a main site and a plurality of acquisition points installed into the distribution line and includes steps as follows. Step 1001: collecting and uploading a traveling wave signal by each of the acquisition points after a fault occurs in the line; step 1002: generating a fault record set; step 1003: computing the shortest paths from a central site to other sites and their lengths; step 1004: using expanded two-terminal traveling wave ranging principle for pairing computation; step 1005: converting positions of possible disturbance points into possible disturbance occurrence time points; step 1006: extrapolating from equal path lengths of the possible disturbance points to obtain disturbance time data; and step 1007: determining a final disturbance point.

Provided is construction of Mucor circinelloides cell factory for producing stearidonic acid SDA and fermentation technology thereof. Δ15 Des gene is obtained by cloning from Mortierella alpina, the gene is ligated to an integrative plasmid pMAT1552, and transformed into a Mucor circinelloides defective strain Mu402, and Δ15 Des is integrated on Mucor circinelloides genome through homologous recombination, to obtain the recombinant strain Mc-Δ15, finally, the expression of the Δ15 Des gene in Mucor circinelloides is realized. The recombinant new strain was preserved in China General Microbiological Culture Collection Center on Jun. 20, 2018, and the address is NO. 1 West Beichen Road, Chaoyang District, Beijing. The center gave the biological material the preservation number CGMCC No. 15888, and the suggested classification name is Mucor circinelloides-D15D.
Abstract:
The present invention relates to a method for automatic identification of an application network topology for power distribution network control which belongs to the field of electric power automation. The method comprises the following steps: 1. statically configuring attributes of a switch; 2. determining, by a power distribution network intelligent terminal STU, whether a query trigger condition is satisfied; 3. sending, by an inquirer, a query command to initiate the query into an application network topology; 4. replying to the query command; 5. receiving the query command; 6. checking the integrity of the switch attribute information; and 7. forming an application network topology. The present method for automatic identification of an application network topology for a power distribution network control has few calculations and can be executed with high speed, ensures the integrity and reliability of information, and is particularly suitable for distributed intelligent control of the power distribution network. The establishment of the application network topology is distributed to each power distribution network intelligent terminal STU, thus reducing heavy calculation, and is suitable for applications having relatively few embedded system software and hardware resources.
Abstract:
This invention relates generally to the field of beer brewing, specifically to a processing method and a device for the extrusion of beer adjunct with or without enzymes added, and a saccharogenic method for the extruded beer adjunct. The processing method and the device of this invention are such that the starch in the beer adjunct extruded with or without enzymes added can be degraded more thoroughly, the saccharification time can be shortened, and the recoverable ratio of wort extract and therefore the production yield of beer can be increased further, as compared to the processing method, the device and the saccharogenic method of the prior art extrusion-cooking version. Meanwhile this invention spared the mashing and liquefying of beer adjunct mash at the temperature of 100 degrees C. as is common in the technology of traditional beer production.
