1. A method for non-invasively measuring the concentration of a substance in a body, comprising: changing a body surface temperature from one temperature to a second temperature； then recovering a first temperature by changing a body surface temperature from a second temperature to a first temperature； measuring a first dose of infrared radiation absorbed or emitted by the body in the first wavelength range at predetermined time intervals during a reconstructive change in the surface of the body from the second temperature to the first temperature ry； measurement of a second dose of infrared radiation absorbed or emitted by the body in the second wavelength range at predetermined time intervals during a restoration of the surface of the body from the second temperature to the first temperature； measurement of the temperature on the surface of the body； measurement of the ambient temperature； calculation of the normalized ratio parameter the basis of the first dose, the second dose, body surface temperature and ambient temperature； and determination of the concentration of a substance in the body is non-invasive, by establishing a correlation of the normalized ratio parameter with the surface temperature of the body and the ambient temperature. 2. The method of claim 1, wherein the first wavelength range is a wavelength range or ranges in which a substance emits and absorbs infrared radiation, and the second wavelength range represents a whole spectrum in which a body emits and absorbs infrared radiation in far infrared spectrum. 3. The method of claim 1, wherein the first wavelength range is a wavelength range or1. Способ для неинвазивного измерения концентрации вещества в теле, содержащий:изменение температуры поверхности тела от одной температуры до второй температуры；затем восстановление первой температуры посредством изменения температуры поверхности тела от второй температуры до первой температуры；измерение первой дозы инфракрасного излучения, поглощаемого или
