A disposable absorbent article comprises a liner, an outer cover and an absorbent body therebetween for absorbing liquid body waste penetrating the liner. In one embodiment, the absorbent body comprises an inner layer and an outer layer. The inner layer has a lower absorbent capacity per unit weight than the outer layer. A flow control layer between the inner layer and the outer layer at least retards the flow of liquid body waste from the inner layer to the outer layer to facilitate a prolonged feeling of wetness to the wearer. In another embodiment, a surge layer lies between the liner and an absorbent body. A flow control layer between the liner and the surge layer, or between the surge layer and the absorbent body, at least retards the flow of liquid body waste through the surge layer toward the absorbent body.

An antiscattering grid for an X-ray imaging apparatus of the type comprising a substrate having a plurality of metallized partitions that together define a plurality of cells distributed over the substrate. The partitions allow passage of the X-rays emitted from a source lying in line with the grid, and absorbing the X-rays not coming directly from this source. The substrate is made of a polymer material that may be formed by radiation curing of a monomer sensitive to this radiation. The substrate may be substantially planar and the partitions may be oriented to form a focused grid.

The invention discloses a foam platform for drilling on waterways. The foam platform comprises a machine station plate used for placing equipment, support legs used for supporting the platform, a drilling operation reserved hole and a hydraulic lifting system of the platform, wherein at least a square foam floating body is fixedly connected to the part below the machine station plate; the foam floating body is arranged in a steel frame; and the machine station plate is fixed on the steel frame directly or indirectly. The foam platform device for drilling on waterways has a simple structure, is connected firmly, can achieve rapid assembly, cannot be influenced by tides or water level changes, and is suitable for being used as a platform for conducting work drilling on waterways in areas, such as shallow water areas, offshore sea, and the like. Compared with a framework working platform, a ship type working platform, an oil drum type working platform, a raft type working platform, a lifting ship body type working platform, and the like, the platform device has remarkable advantages, can meet the use requirement of drilling work in areas influenced by water level lifting, such as offshore sea, river shallow water, and the like, and improves the working efficiency and the economic benefits of drilling on waterways.

The invention provides an insulating and antibacterial automobile ceiling fabric. Silicon dioxide aerogel is used as a functional packing layer, the very poor water absorption property of the silicon dioxide aerogel is beneficial to keeping the overall dryness of the automobile ceiling fabric, due to addition of hyperbranched polymer bactericide, not only is the formation of the aerogel felt accelerated, but also the mechanical strength of the aerogel felt is improved, the bacteria can be effectively killed and inhibited, the automobile ceiling fabric is prevented from mold or bacteria, and the body health of passengers is ensured. The automobile ceiling fabric provided by the invention integrates an insulating material aerogel felt layer and a stainless steel vacuum insulating layer, and a good insulating effect is achieved as the aerogel felt is of a porous structure of nano grade aperture and a heat conduction path is blocked by the vacuum insulating layer. The invention further provides a preparation method of the aerogel felt. Due to addition of the hyperbranched polymer bactericide as a functional auxiliary agent, the aerogel felt has properties of sterilization and bacteriostasis, is very poor in water absorption property and is beneficial to keeping the overall dryness of the automobile ceiling fabric.

The invention discloses a preparation technology of black tea pearl rice. The preparation method comprises the following steps of: extracting concentrated solutions of black tea, green tea, corn stigma, poria cocos and radix puerariae respectively, and uniformly mixing the concentrated solutions with the prepared oyster mushroom slurry, tremella slurry, ramie oil and hippophae rhamnoides powder; stirring the mixture with corn powder, millet powder and polished round-grained rice powder to obtain granules; performing the puffing and extrusion processes with granulation equipment, and forming with a die to obtain golden yellow and bright black tea pearl rice the same as rice grains; and drying, finishing, sterilizing and packing to obtain a finished product.
