A purification method for detection of a strontium isotope in a silk cultural relic. The method includes: (1) enrichment of the strontium isotope: after cleaning the silk cultural relic, adding the silk cultural relic to a digestion agent for microwave digestion, and conducting evaporation drying; and adding a dried product to a nitric acid solution for centrifugal separation, and extracting a supernatant; and (2) purification of the strontium isotope: first, mixing 4',4″(5″)-di-tert-butyldicyclohexano-18-crown-6 and a defoamer and adsorbed to a purified resin separation column, and pre-cleaning the purified resin separation column with a nitric acid solution; next, injecting the supernatant in step (1) into the purified resin separation column with a nitric acid solution as a carrier solution; and then, injecting anSr solution and an elution solution into the purified resin separation column in sequence to obtain a separated and purified strontium solution.

The embodiments of the present application provides a method and apparatus for preventing heat damage to a thermal imaging camera. The method includes: obtaining a thermal imaging picture of the thermal imaging camera; detecting whether the thermal imaging picture shows that a high-temperature object appears in the picture of the thermal imaging camera; confirming that the thermal imaging picture shows that a high-temperature object appears in the picture, generating a heat damage alarm signal, and closing a baffle if the baffle is not closed currently. In the present application embodiments, after detecting a heat damage alarm signal, that is, after detecting that a high-energy radiating object enters an image picture, the baffle is closed immediately, thereby avoiding the risk of the sensor being permanently burnt due to directly face to the high-energy radiating object.
