Abstract: A method for preparing modified calcined kaolin particles with surface amphiphilicity. The method includes the steps of drying and sieving the calcined kaolin particles, adding ethanol, and stirring to obtain a suspension A, preparing an ethanol solution of a vinyl silane coupling agent, and stirring for a period of time at a certain temperature to obtain a solution B, dripping the solution B into the solution A, and stirring for a period of time at a certain temperature to obtain a suspension C, reducing the temperature of the suspension C, introducing nitrogen, adding a certain amount of sulfhydryl compound, stirring for a period of time at a certain temperature to obtain a suspension D, filtering, washing and drying to obtain the modified calcined kaolin particles.

Abstract: A blood vessel imaging temperature measurement method is provided. The method comprises the steps of finding blood vessels, displaying a measurement position, and aligning for temperature measurement to achieve visual and precision temperature measurement. The temperature measurement is quite visual, instead of the traditional technology that uses a blind measurement method corresponding to a position to be measured, thereby solving the problem that the temperature measurement is not accurate enough in the traditional technology.
