Abstract: An injection regulation and control device includes blast furnace tuyeres for introducing rich oxygen or pure oxygen to form tuyere raceways. Temperature-adjusting injection openings are evenly formed in the circumferential direction of a blast furnace and inject a hydrocarbon component-containing injection object to the blast furnace. The temperature-adjusting injection openings are located, in an axial direction, within a height range where a soft melting dripping zone is located and are not lower than the positions of the blast furnace tuyeres. The hydrocarbon component-containing injection objects are enabled to undergo a thermal cracking reaction by utilizing the temperature in the vicinity of the tuyere raceways to form a hydrocarbon thermal cracking heat absorption area. Gas products generated by the thermal cracking reaction of the hydrocarbon component-containing injection objects increase the blast furnace gas volume.

Abstract: A method, apparatus, and/or system for soft defects modeling of measurements using time-domain reflectometry. Electro-Optic Sampling based Time-Domain Reflectometry (EOS-TDR) may quickly detect soft defects in a chip under test. For example, EOS-TDR may detect soft defects in each pin from a trace-structure point at a relatively high resolution. To interpret the results in a time sensitive manner, a reference model for chips may be established from chips that are known to have met the expected quality standards. Through automated analysis of the features of the device under test waveform, soft defects of a chip may be detected that would be otherwise undetectable under time constraints, temperature variations, applied current variations, applied voltage variations, vibration variations, moisture variations, or any other kind of possible variation.
