A vibration-isolating fixing mechanism for a fan frame. The mechanism, configured to couple the fan frame to first fastening portions of a casing, includes: coupling portions protrudingly disposed on two installation surfaces of the fan frame; positioning brackets each having second fastening portions and through-holes; resilient elements each circumferentially disposed between each coupling portion and each through-hole and extending to two through-hole-corresponding sides of each positioning bracket; and coupling elements coupled to the coupling portions respectively, positioned on one side of each resilient element facing away from the fan frame, and configured to position the positioning brackets and the fan frame relative to one another. Axial vibration isolation is achieved by insertion of the coupling portions into the through-holes circumferentially disposed with the resilient elements and by resilient contact between each resilient element and each coupling element.

Disclosed is an absorptive article (1) that comprises a hydrolytic surface sheet (2), a hydrolytic back sheet (3), and a hydrolytic absorber (4) provided between the surface sheet (2) and the back sheet (3). The back sheet (3) is configured of multiple sheet fragments (3A-3D), which are smaller than the main body of the absorptive article (1). The sheet fragments (3A-3D) are at least partially overlapped with each other. An adhesive (5) is applied to the overlap areas where the sheet fragments (3A-3D) are overlapped with each other.

The invention provides a preparation method of a carbon nanometer fiber / beta-cyclodextrin based nanometer fiber film with a sandwich structure. The method is characterized in that the nanometer fiberfilm employs beta-cyclodextrin as a substrate, citric acid as a cross-linking agent, beta-cyclodextrin as a reinforcing phase, and a polymer for assisting film forming, and is the nanometer fiber filmwith the electrospun carbon nanofiber enhanced polymer / beta-cyclodextrin-polyacrylic acid / polymer three-layer sandwich structure. The nanometer fiber film with the sandwich structure has good adsorption and fixation effects for heavy metal ions (such as Cd(II), Cu(II), Fe(III) metal cations) in aqueous solution. The preparation process has the advantages of simple and easy operation, easily available raw materials, environmental friendliness, and low cost, and the method can be applied to water treatment and biomedical fields which need high efficient separation and fixation of heavy metal ions.
