The invention relates to a magnesium smelting reduction pot and a preparation method thereof, which belong to the technical field of metal smelting. The magnesium smelting reduction pot comprises a pot body and an external application coating layer, and is characterized in that: the pot body comprises the following components in percentage by weight: 0.2 to 0.4 percent of C, 1.0 to 2.0 percent of Mn, 0.6 to 2.0 percent of Si, 24.0 to 26.0 percent of Cr, 6.0 to 8.0 percent of Ni, 0.015 to 0.05 percent of Ti, 0.03 to 0.10 percent of Re, and the balance of iron; and the external application coating layer comprises the following components in percentage by weight: 47.9 to 74.1 percent of zircon powder or graphite with the particle size of 200 to 270 meshes, 1.5 to 3.8 percent of bentonite, 1.5 to 2.9 percent of powdered cellulose (carboxymethylcellulose sodium), 0.7 to 2.4 percent of white latex (polyvinyl acetate emulsion), and 22.2 to 43.0 percent of ethanol. All types of the components of the pot body are put into an intermediate frequency furnace and are melted for pouring, and are brushed with a coating according to the component proportion after being cooled. Starting from each process step of preparing the magnesium smelting reduction pot, the components of materials of the reduction pot, a melting process and a centrifugal casting process are optimized and adjusted, and a high-temperature resistant coating is brushed on the surface of the reduction pot to effectively promote the oxidation resistance of the reduction pot at a high temperature, so the service life of the pot body is prolonged.

The invention discloses a flexible protective material with remarkable impact resistance and vibration suppression performance and a preparation method thereof. The protective material is an SR-RIRM-CNT material, wherein SR is silicone rubber, RIRM is a repairable impact reinforcing material, CNT is a carbon nanotube, and the flexible protective material is formed by compounding the three materials. The SR-RIRM-CNT composite material disclosed by the invention not only has excellent impact resistance and vibration suppression performance, but also has good flexibility. Compared with a traditional impact-resistant vibration suppression material, the SR-RIRM-CNT composite material has more excellent dynamic mechanical properties under the impact load, and the suppression effect on the high-speed impact vibration load is more remarkable.

The invention relates to a preparation for inhibiting adverse reaction of opioid analgesic drugs and application of the preparation. The preparation contains one or more of 17-N-allylamino-17-demethoxygeldanamycin or / and homologs thereof, and the opioid analgesic drug comprises one or a combination of more of a morphine hydrochloride tablet, a morphine sulfate sustained-release tablet, a codeine phosphate tablet, a morphine hydrochloride injection, a piperidine hydrochloride injection and a fentanyl injection. By the adoption of the technical scheme, 17-AAG can obviously inhibit the symptom ofprecipitation withdrawal reaction along with chronic administration of morphine, body tolerance and mental dependence of morphine can be obviously inhibited, 17-AAG and homologs thereof and opioid analgesic drugs are reasonably used. Meanwhile, the compound has dual effects of resisting tumors and inhibiting the tolerance and dependence of opioid analgesic drugs, so that the use of other drugs can be reduced.

The invention discloses a super-radiation light-emitting diode chip integrated with a lateral detector and a preparation method, the super-radiation light-emitting diode chip comprises a substrate and an epitaxial wafer formed on the substrate, and an isolation groove penetrating through the epitaxial wafer downwards is formed in the upper surface of the epitaxial wafer. A ridge waveguide arranged in parallel with the isolation groove is formed on one side, corresponding to the isolation groove, of the upper surface of the epitaxial wafer, and an active area and a passive absorption area are sequentially formed on the side in the length direction of the ridge waveguide. A lateral detection area is formed on the other side, corresponding to the isolation groove, of the epitaxial wafer and at the position opposite to the active area, the ripple coefficient of the super-radiation light-emitting diode can be effectively improved, and the influence of introduction of a passive absorption area on the light detection capacity of a lateral detector is reduced.
