Problems solved by technology

But this method is not suitable for measuring trace substances, such as the temperature change of solid powder below 1 gram
On the one hand, the mass of the substance to be measured is too small, so that the thermocouple probe cannot fully contact the surface to be measured; on the other hand, the temperature change of the substance to be measured is weak, and the heat loss to the surrounding is too fast, so that the thermocouple probe cannot fully reflect the actual temperature. temperature
This makes it difficult to study the temperature rise of ferromagnetic powders in an alternating magnetic field

Embodiment Construction

[0022] The present invention shows the method of ferromagnetic material temperature rise by simulating vascular bed,

[0023] 1. Fabrication of simulated vascular bed:

[0024] (1) Heat a piece of blood cover on the flame of an alcohol lamp for 2 minutes, then place it flat on a copper plate, and the blood cover will break into several parts when it is cold;

[0025] (2) Splicing the fragments on the glass slide with double-sided tape, leaving a gap of 0.5mm-1.5mm between the cracks, which is the simulated blood vessel;

[0026] (3) Drop a little molten polyethylene glycol with a molecular weight of 2000 between the two layers of glass slides, and form monolayer regular, radial, polygonal crystals after the tiled polyethylene glycol is cooled;

[0027] (4) After the polyethylene glycol is solidified, the polyethylene glycol in the gap is removed, and dry 10 mg of ferric oxide powder is filled in the above gap to obtain a simulated vascular bed;

[0028] (5) Repeat the above ...

Abstract

This invention relates to analogue blood bed display iron magnetic substance heating method, which comprises the following steps: quickly cooling it down and cracking it into parts; re-piecing the cracked blood cover slices on the glass slides with gaps between; dripping melted poly glycol between blood cover slice and glass slice; deleting the poly glycol in gaps after the poly glycol solidified; filling the dried iron magnetic power to the above gaps to get the analogue blood bed; putting the above analogue blood bed in the alternating magnetic field and then putting the analogue blood bed under bias microscopes for observation.

Description

technical field [0001] The invention relates to a method for displaying the temperature rise of ferromagnetic material by using simulated blood vessel bed, in particular to a temperature measurement method for displaying the temperature rise of ferromagnetic powder in alternating magnetic field by using simulated blood vessel bed. Background technique [0002] At present, the commonly used contact method to quickly measure the surface temperature of an object is to use a thermocouple thermometer to measure the temperature. It has the characteristics of fast, accurate and high sensitivity. But this method is not suitable for measuring trace substances, such as the temperature change of solid powder below 1 gram. On the one hand, the mass of the substance to be measured is too small, so that the thermocouple probe cannot fully contact the surface to be measured; on the other hand, the temperature change of the substance to be measured is weak, and the heat loss to the surroun...
