A system and method for monitoring accumulation of fluids in a containment tank is provided. The system may be operable to and method may function to prevent (i) fluids destined for an underground storage tank (“UST”) from entering into, diffusing into and/or contaminating the ground soil due to, for example, spillage or overflow of a fill pipe of the UST when filing or otherwise servicing the UST, and/or (ii) fluids present in the ground soil from entering into and/or contaminating fluids stored in the underground storage tank. The system may include a first containment chamber that defines a given volume; a second containment chamber that may be positioned substantially within the given volume; an accumulation zone defined by a volume between the first and second containment chambers; and a monitoring device for detecting accumulation of fluids in the accumulation zone.

Provided is a blower fan comprising a fan frame, an impeller and at least one air-guide duct. The fan frame is provided with an air inlet, an air outlet and the containing space. The air inlet and the air outlet are communicated with the containing space and the containing space can be divided into an air-out zone and a pressure accumulation zone. The impeller is arranged in the containing space. The at least one air-guide duct is used to combine the fan frame and to communicate with the containing space, wherein the at least one air-guide duct is provided with an air-in end and an air-out end with the air-in end placed at the pressure accumulation zone and the air-out end facing at least one heat source. Thereby, the blower fan is able to carry out heat radiation for several different positions by simultaneously using the air outlet and the at least one air-guide duct so as to produce better radiation effects.

The invention discloses a method for calculating the flow attenuation value of a debris flow accumulation area. The method comprises the steps that a gully gradient ratio J, a debris flow depth H and a debris flow gully width B of a gully accumulation area of earthquake region debris flow are acquired; the obtained parameters are substituted into an attenuation value calculation formula for determining the flow alphq of the earthquake region debris flow, and the debris flow prediction flow attenuation value in the debris flow accumulation process can be obtained. The method is suitable for flow attenuation value prediction in the accumulation process of the earthquake region debris flow. Compared with the prior art, the method is based on strict theoretical derivation, the attenuation condition of the flow of the earthquake region debris flow in the accumulation area can be obtained more accurately, and a basis is provided for design of drainage groove control projects of the gully accumulation area of the earthquake region debris flow; the method is easy and efficient to use, and can meet the requirement for geological disaster prevention.

The invention provides a study method for reservoir formation possibility of a basin-edge negative structure. The study method for reservoir formation possibility of the basin-edge negative structurecomprises the following steps: step 1, fluid inclusion samples are collected from a target-interval reservoir, and oil-gas accumulation stage of a study area is determined according to measurement andanalysis of homogenization temperature of fluid inclusion; step 2, sand body distribution laws are determined through paleostructure restoration and sedimentary reservoir analysis, so that oil-gas migration directions, oil-gas transport systems and maximum ranges of oil-gas in different reservoir formation stages are determined; step 3, possible oil-gas accumulation zones are predicted accordingto the oil-gas migration laws in the reservoir formation stages obtained in step 2 in combination with the existing favorable trap analysis. The study method for reservoir formation possibility of thebasin-edge negative structure is an effective study method which has practical operability and integrates all geological factors, and the problem about reservoir formation possibility of the basin-edge negative structure is solved.

A media accumulator-ejector for use with an imaging apparatus. Rotatable upper and lower roll assemblies are located above and below a media accumulation zone comprised of an accumulation plate and positioned to receive media exiting an imaging device. The roll assemblies are moveable like jaws between an open position where media can accumulate on the accumulation plate without interference with the roll assemblies and a clamping position where the accumulated media is grasped by the upper and lower roll assemblies. The upper and lower roll assemblies are then rotated to eject the accumulated media from the accumulation plate. The upper and lower roll assemblies can also grasp and continuously eject individual sheets of media at a predetermined process speed.
