The invention discloses application of a substance for detecting the content of iron ions in preparation of a product for diagnosis and prognosis of a fever with thrombocytopenia syndrome. The invention further discloses application of the substance for detecting the content of the iron ions in screening patients with the fever with thrombocytopenia syndrome, evaluating prognosis survival conditions or death risks or tissue damage degrees of the patients with the fever with thrombocytopenia syndrome and monitoring change of disease degrees of the patients with the fever with thrombocytopenia syndrome. It is found for the first time that the content of iron ions in serum can effectively assist in diagnosing the fever with thrombocytopenia syndrome, meanwhile, the method has an important assisting and guiding effect on prognosis of development of the fever with thrombocytopenia syndrome, doctors can conduct definite diagnosis conveniently, and a reasonable treatment scheme can be made according to prognosis.

The present invention belongs to the technical field of nanocrystalline soft magnetic materials, and discloses a high magnetic permeability nanocrystalline cut iron core and its preparation method and application. The preparation method comprises: winding or further processing an iron-based nanocrystalline alloy thin strip into a target shape, and then annealing to obtain an amorphous nanocrystalline iron core; then performing a paint immersion curing treatment, and cutting the cured iron core into a C-shaped iron core; mechanically grinding the cut surface of the obtained C-shaped iron core, and using a grinding fluid containing abrasive for cooling during the grinding process to obtain the high magnetic permeability nanocrystalline cut iron core. The present invention repairs the cut surface of the nanocrystalline iron core by mechanical grinding. When two bright cut surfaces are butt-jointed together, the high-frequency magnetic permeability can be restored to more than 80% of that when the closed magnetic circuit is not cut, thereby achieving high-frequency high impedance characteristics, which can be applied to high current and high power scenarios.

The utility model provides a kind of sulphuric acid residue efficient utilization sintering equipment, including sintering furnace, the side of sintering furnace is provided with screening cylinder, spiral disc is fixedly connected in the screening cylinder.The utility model has the advantages that: the inertia of sulphuric acid residue with higher iron element content is stronger, it moves to discharge plate over drop hole, and rolls to screening box along discharge plate.Start motor drives magnetic roller to rotate, sulphuric acid residue in screening box falls on magnetic roller under the action of inertia, sulphuric acid residue with more iron content relative to its mass is adsorbed and driven to rotate by magnetic roller, sulphuric acid residue with less iron content relative to its mass flows along magnetic roller to enter discharge cylinder at through hole, so that the magnetic separation of sulphuric acid residue is realized.Sulphuric acid residue with higher iron element content enters sintering furnace through material passage, and completes ironmaking work with other ironmaking raw materials.Sulphuric acid residue is automatically screened, and two screening procedures are passed, and ironmaking raw material has higher iron element content, which is conducive to improving ironmaking quality.
