    Abstract: The disclosure relates to the technical field of electrolysis cells, and in particular to a solid oxide electrolysis cell (SOEC) and a preparation method thereof. The SOEC provided by the disclosure adopts an n-type TiO2 layer and a p-type La0.6Sr0.4Co0.2Fe0.8O3−δ layer as an electrolyte layer. Although the n-type TiO2 and the p-type La0.6Sr0.4Co0.2Fe0.8O3−δ have both ionic and electronic conductivities, the electric field effect of a PN junction between the two layers can effectively cut off the transmission of intermediate layer electrons and enable ions to rapidly pass through. The SOEC can effectively avoid short circuit and exhibit excellent performance. Furthermore, the above structure allows the SOEC to have a stable performance output, and the SOEC can be produced on a large scale due to low material cost.

    Abstract: The present disclosure discloses use of TM9SF1 gene as a target in vascular diseases, which relates to the field of biotechnology. In the present disclosure, by means of RNA interference strategy, it is found that after endogenous TM9SF1 gene is interfered with, the expression of two important genes IL1β and IL8 related to the inflammation of HUVEC and the expression of the gene ACE1 closely related to vasoconstriction are remarkably downregulated, suggesting that TM9SF1 gene has positive regulation effect on the expression of IL1β, IL8 and ACE1 genes. By inhibiting or silencing the expression of the TM9SF1 gene, it is possible to inhibit or silence the expression of IL1β, IL8, and ACE1 genes, and further achieve the object of treating or preventing vascular diseases associated with the expression level of IL1β, IL8 and ACE1 genes.

    Abstract: In a method of critical displacement forecast based on the deformation failure mechanism of slope, a sliding surface displacement, a calculation based on status stability factors and a slope surface displacement are determined, and applied for forecast based on a thrust-type slope deformation mechanism, a key compartment division, a relation between stress and strain mechanics properties of sliding surface of geo-material, and an analysis of evolution characteristics at different points of the sliding surface. The method provides advantages of determining deformation values at different points of a sliding surface, a slope body and a slope surface during slope failures; describing the process of a progressive failure, deformations and force changes of a slope; combining slope monitoring values to perform the stability analysis and the calculation of the magnitude of the stability factors in different deformation statuses of the slope; and assessing the durability of protective measures to the slope.

    Abstract: A method for breeding polyploid two-line hybrid rice includes determining a tetraploid rice photo thermosensitive genic male sterile line with the gene characteristic of PMeS (polyploid meiosis stability) and a tetraploid rice restoring line with the gene characteristic of PMeS; hybridizing and matching by indica sterile/japonica restoring or japonica sterile/indica restoring hybrid combination; preparing a tetraploid rice hybrid by adopting a tetraploid rice photo thermosensitive genic male sterile line and a tetraploid rice restoring line; and breeding a stable tetraploid rice hybrid combination which is determined as the polyploid two-line hybrid rice combination. The breeding method disclosed by the present invention utilizes the strong heterosis of polyploid rice, and transforms the existing diploid heterosis into the heterosis of polyploid two-line hybrid rice; and by adopting the method disclosed by the present invention, a new polyploid two-line hybrid rice variety with large ears, large grains and high yield can be bred.
