The invention relates to a thermal conduction mechanism of a weighting sensor temperature compensating testing device, which consists of two groups of conduction fastening devices symmetrically arranged on a test platform and having same structure, wherein each conduction fastening device comprises a base, a conduction board, a cooling plate, a fan, an air cylinder, a bracket and a spring, the air cylinder is arranged on the base, the piston rod of the air cylinder is connected with the rear part of the bracket, fastening pieces pass through supporting seats at two sides of the cooling plate to be connected in threaded holes at two sides of the bracket in a screwed way, and springs are also arranged between the supporting seats of the cooling plate and the bracket, the rear part of the cooling plate is provided with the fan, and the front end of the cooling plate is provided with the conduction board; two conduction boards on the two conduction fastening devices correspond to each other, and a distance a for placing a weighting sensor is left between the two conduction boards. The invention can enable the weighting sensor to quickly reach thermal equilibrium of tested temperature while carrying out temperature compensation test to the weighting sensor, thereby saving energy and greatly enhancing the test efficiency of the test.

The invention relates to a structure for improving the reliability of a storage unit of a phase-change memory and a manufacturing method thereof, which is characterized in that a thin layer of buffer material is added between a nano-heating electrode and a columnar phase-change material with the same diameter to strengthen the phase-change material and the phase-change material. The adhesion and interface matching between heating electrodes can improve the electrical matching between phase change materials and heating electrodes at the same time, forming a good ohmic contact. In addition, a thin layer of thermal resistance material is added between the phase change material and the item electrode to improve the thermal balance of the device during erasing and writing, reduce the heat dissipation of the upper electrode, and reduce the power consumption of the device. The memory unit structure prevents the diffusion between the phase change material and the heating electrode and the interface failure in the process of repeated erasing and writing, and enhances the reliability of the device. The heating electrode, the buffer material and the phase change region are confined in the same dielectric hole to form a self-aligned columnar structure, which does not require an insulating layer around the phase change material, reducing the number of process steps.

The invention provides a non-invasive human body core temperature detection probe and method, including a probe heat conduction layer, at least three heat transfer units with different heights and a control unit; by setting the heat transfer unit and heater, according to the heating treatment, the establishment of thermal balance is accelerated, Improve the rapidity of human body core temperature detection; improve the ability of the detection device to resist environmental factors by using an adaptive filter based on the minimum gradient algorithm; through the combined compensation of at least three heat transfer units in the human body core temperature detection probe due to the uneven lateral heat flow of the human body The measurement error caused by uniformity improves the detection accuracy.
