Method for measuring heat conductivity coefficients of explosives and powders by using single-side method and double probes

The invention discloses a method for measuring the heat conductivity coefficient of explosives and powders by using a single-side method and double probes, which comprises the following steps of: placing a sample to be measured on a sample bearing table of a measuring system, and closing a box door; setting the temperature in the constant-temperature box to be T which is any temperature in a range of-50 to 70 DEG C, after the temperature in the constant-temperature box is stable, adjusting a temperature detector to enable a contact of a probe to be in close contact with the surface of the to-be-tested sample, starting measurement, stopping measurement after the measurement time exceeds 10 minutes, obtaining m groups of measurement results of the current position of the to-be-tested sample, and calculating a thermal conductivity coefficient value; adjusting the contact position of a probe contact of the temperature detector and the to-be-detected sample to obtain heat conductivity coefficients of different pos
