The present invention relates to a vaginal sustained-release drug delivery system for luteal support and a method for preparation and use thereof. The vaginal sustained-release drug delivery system for luteal support is a progesterone depot-type vaginal ring having a bilayer structure of a core layer and a film layer enclosing the core layer, wherein the core layer is composed of a solid scaffold carrier of medical EVA containing a drug uniformly dispersed therein, and the film layer is composed of a medical EVA material containing no drug. The vaginal sustained-release drug delivery system for luteal support according to the present invention can be used for assisted reproduction and for treatment of functional uterine bleeding, premenstrual syndrome and the like due to luteal phase defect with a significantly improved therapeutic effect.

Provided are an oxovanadium phosphate catalyst, and a preparation method and an application therefor. The method includes: 1) mixing and reacting a vanadium source, a choline chloride-organic carboxylic acid eutectic solvent, and alcohol; 2) mixing the obtained reaction product with a phosphorus source, raising the temperature to a temperature higher than the melting point of the eutectic solvent, and continuing the reaction to obtain an oxovanadium phosphate precursor; and 3) calcining to obtain the oxovanadium phosphate catalyst. The alcohol is: benzyl alcohol or a mixture of C-Cmonohydric alcohol and benzyl alcohol. The present method uses a green and inexpensive eutectic solvent to strengthen the preparation of oxovanadium phosphate catalyst, avoids the disadvantages of the prior art, and overcoming the problems of low yield and poor selectivity when used in a reaction to prepare maleic anhydride by catalytic n-butane selective oxidisation.

Oxovanadium phosphate catalyst, and preparation method and application therefor

The present application relates to geophysical survey, particularly provides an inversion velocity model, a method for establishing the same and a method for acquiring images of underground structure. The method for establishing inversion velocity model comprises: converting observation seismic records into first intermediary data which contains data with frequency no higher than a first predetermined frequency; calculating synthetic seismic records based on a set initial velocity model and converting the synthetic seismic records into second intermediary data which also contains data with frequency no higher than the first predetermined frequency; establishing an objective function based on the first intermediary data and the second intermediary data; calculating a velocity gradient of seismic wave based on the objective function; calculating a iteration step of the velocity gradient; determining the inversion velocity model based on the velocity gradient and the iteration step.
