Abstract: A method for fault location to single-terminal traveling wave includes steps as follows. Step (a): recording a waveform of a traveling wave signal of disturbance by a traveling wave device when a line disturbance occurs. Step (b): performing a phase mode transformation on the waveform recorded by the step (a), so as to obtain components of line mode and zero mode of a fault initial traveling wave, and performing a wavelet transform to decompose the components of the line mode to obtain singularities in the waveform of the traveling wave. Step (c): calculating a wavefront slope k of the components of the line mode of the fault initial traveling wave. Step (d): computing a preliminary fault distance D according to the slope k computed in the step (c). Step (e): confirming a fault point according to the preliminary fault distance and wavelet singularities of the components of the line mode. Step (f): end.

Abstract: The present disclosure relates to a construction method of a Mucor circinelloides cell factory for producing dihomo-γ-linolenic acid and a fermentation technology, belonging to the field of genetic engineering. In the present disclosure, γ-linolenic acid elongase gene glelo is obtained from Mortierella alpine by cloning, the gene is ligated to an integrative plasmid pMAT1552, and transformed into a Mucor circinelloides defective strain Mu402, and the gene glelo is integrated into Mucor circinelloides genome through homologous recombination, to obtain the recombinant strain Mc-glelo, and finally, the expression of the gene glelo in Mucor circinelloides is realized. The lipid content in the recombinant strain Mc-glelo is not obviously different from that in the control strain Mc1552, however, the lipid composition changes greatly, and dihomo-γ-linolenic acid appears in the lipids of the recombinant strain Mc-glelo, and the content thereof reaches 5.7% of the total fatty acids. Under optimized fermentation conditions and in the presence of precursor fatty acid, the DGLA content reaches 7.6%. The new recombinant strain was deposited in China General Microbiological Culture Collection Center on Jun. 20, 2018, with the address of No. 3, Courtyard 1, Beichen West Road, Chaoyang District, Beijing. The accession number given to the biological material by the collection center is CGMCC No. 15887, and the suggested taxonomic denomination is Mucor circinelloides-GLELO.

The method for controlling an amount of silicon added to ductile cast iron includes smelting ductile cast iron using scrap steel as a raw material. After the scrap steel is melted into molten iron, a copper alloy is added so that the molten iron has a copper equivalent of 0.8% to 1.0%, wherein the copper equivalent is controlled by formula (II). Then, ferrosilicon is added so that the content of silicon added to the molten iron satisfies formula (I).
