    摘要: The invention provides an acoustic material structure and an assembly method of the acoustic radiation structure. The acoustic material structure comprises acoustic units which can be attached onto surfaces of acoustic radiation structures. Each acoustic unit comprises a thin sheet, an air cavity between the thin sheet and the surface of the sound radiation structure, and openings penetrating through the acoustic unit with one end connected to the cavity. The openings can reduce the spring effect of the fluid medium in the cavity, so that the acoustic units attached onto the surface of the sound radiation structure can provide low-frequency sound insulation effects. The acoustic unit may also include support bodies, mass blocks, and constraint bodies. The working frequencies of the acoustic unit can be regulated by the support bodies, mass blocks and constraint bodies. The acoustic material structure can effectively suppress sound radiation from low- and middle-frequency sound waves which have relatively larger wavelength under costs of small weight and space. Moreover, the acoustic material structure can enhance the exchange rate of the heat from the attached structure surfaces by the vibration of the thin sheet.

    摘要: Use of 9,10-anthraquinone compounds of formula (I) or pharmaceutical salts thereof or plant extracts containing said compounds in the preparation of anti-HCV medicaments is disclosed, in which Y1 are Y2 are independently hydrogen, hydroxyl or groups of formula (II); and R1, R2, R3, R4, R5 and R6 are independently hydrogen, hydroxyl, carboxyl, cyano group, nitro group, groups of formula (III) or groups selected from those substituted or unsubstituted groups: amino, C1-C6 aliphatic hydrocarbon, C3-C7 cyclic aliphatic hydrocarbon, C1-C6 alkoxy, C2-C7 carbalkoxy, C1-C4 acyloxy, C6-C20 aryl, or 5 to 7 members heterocyclic or benzoheterocyclic thereof; or R5 and R6 form the group of formula (IV). The compounds of present invention are cheap, safe and effective because that they mostly come from traditional Chinese medicines and have better anti-HCV effects and lighter side effects.
