The invention relates to carrier particles for use in pharmaceutical compositions for the pulmonary administration of medicaments by means of dry powder inhalers. In particular, the invention relates to a novel technological process for obtaining a carrier modified so as to improve the efficiency of redispersion of active particles and hence increase the respirable fraction. After the treatment of the invention, the surface of said modified carrier particles can also be coated with a suitable additive so as to further improve the respirable fraction.

The invention discloses an apparatus for preparing synthetic gas with adjustable H2 / CO proportion by methane-rich gas and a method thereof. The apparatus comprises a fuel reactor, an air reactor, a first cyclone separator, a second cyclone separator, a material returning valve 1, a material returning valve 2 and a material returning valve 3; a bubbling fluidized bed is arranged at bottom of the fuel reactor, a lifting pipe is arranged at upper part of the fuel reactor; the bubbling fluidized bed is connected to the air reactor through the material returning valve 1, the upper part of the air reactor is connected to the first cyclone separator, a blanking tube of the first cyclone separator is connected to the lifting pipe through the material turning valve 2, the upper part of the lifting pipe is connected to the second cyclone separator, and the blanking tube of the second cyclone separator is connected to the lower part of the bubbling fluidized bed through the material turning valve 3. By adjusting the circulation volume of oxygen carrier and stay time in the bubbling fluidized bed, the reduction depth of the oxygen carrier in the bubbling fluidized bed can be controlled, proportion of H2 / CO at a synthetic gas outlet can be adjusted, subsequent synthesis technology is convenient, CO2 can be instantly separated and captured, and separating step can be avoided.

The invention relates to the technical field of making wine, and particularly relates to jack fruit wine and a preparation method of the jack fruit wine. The method comprises steps of mixing peeled jack fruit with water and preparing into pulp; then adding amylase, cellulose and pectinase into the pulp for enzymolysis so as to obtain enzymatic hydrolysate; then mixing with water and sugar, sterilizing so as to obtain mixed liquor; adding saccharomycetes into the mixed liquor for anaerobic fermentation so as to obtain fermented liquid; filtering, sterilizing and ageing the fermented liquid so as to obtain the jack fruit wine. The preparation method is simple and has high use ratio of the fruit; the jack fruit wine prepared by the method has low alcoholic strength, rich jack fruit flavor and highlighted bouquet, and is fresh and cool.

The invention relates to a comprehensive utilization method of a coal-based oil residue. According to the method, a heated solid heat carrier is mixed with the coal-based oil residue by using a solid heat carrier method; the oil residue is heated and gasified and partially pyrolyzed by using sensible heat of high-temperature solids; heavy liquefied oil in the coal-based oil residue is recovered after being pyrolyzed and gasified; the residual un-gasified residue enters a hot blast heater of a circulating fluidized bed to fully burn; one part of heat generated by combustion is used for heating the solid heat carrier; the other part of heat is recovered through a waste heat boiler. The comprehensive utilization method is small in investment, easy to implement, and high in overall efficiency.

The invention discloses a liquid chromatography-mass spectrometry screening method for multi-target antithrombotic substances based on dried blood spot samples, which belongs to the field of drug screening. The method comprises the following steps: rehydrating the dried blood spot sample, optionally several substrates of key target enzymes involved in the thrombus formation process, mixing several substrate standard solutions with the substances to be screened and then adding them to the rehydrated In the dried blood spot sample, the reaction solution is processed and analyzed by liquid chromatography-mass spectrometry to screen for substances with multi-target antithrombotic activity. The screening method of the present invention is simple and quick to operate, has high accuracy and strong specificity, and can continuously analyze a large number of samples. The target of substance action is clear, which lays a theoretical foundation for the subsequent drug development. The reagents used are easy to obtain, the degree of operation automation is high, clinical promotion and popularization are easy, and the commercial value is high.
