So when you step on a patch of ice, you exert pressure on the ice, which causes its molecules to move closer together. That makes them revert to their more dense state, which is water.

The Ids RNA or siRNA obtained by said invention is mixed with hepatitis B virus expression vector in proper proportion, and injected into the mouse body by vane caudalis hydraulic pressure method, and its result shows that the non-homologous sequence IdsRNA and siRNA basically do not inhibit the replication of hepatitis B virus in mouse body, and these RNA molecules are mixed with hepatitis B virus gene.

The results indicated that the composite films exhibited much improved gas sensing performance.The phthalocyanine and its a-Fe2O3 embedded nano-particulate LB filmswere prepared by Langmuir-Blodgett technique. The films were characterized by AFM, UV-Vis and FT-IR spectra. The results indicated that the embedded LB films were composed of a-Fe2O3 nanoparticles and isopropoxyphthalocyanine molecules. The gas sensitivity of such prepared composite LB films was greatly improved. The film could detect 5ppm of propyl alcohol at room temperature. The composite films could be considered as gas-sensors for alcohols.

The result showed that the assembly of the constructed molecules agreed with the actual mid-boiling points, the concentration of structural groups, average molecular weights, and the ring and side chain distributions. The correlation of properties between pure compounds and complex mixtures of heavy oils could be built by the proposed method.

The difference between the test groups and the control group was statistically significant. It could be deduced that all the insecticides tested in this experiment damaged the spiders′ intestinal mucosa, compromising its function as a barrier and letting large molecules such as FTIC-D more easily penetrate. Among the insecticides, pyrethrin and Bt preparation are bio-insecticides, and the FITC-D concentrations of the spiders exposed to these two bio-insecticides were more than those of the spiders exposed to the chemical insecticides imidacloprid and dipterex. The difference between the bio-insecticide groups and the imidacloprid group was significant, but there was no significant difference between the bio-insecticide groups and the dipterex group.
