The diesel particulate filter device is located further away from the engine than the selective catalytic reduction device. The first connecting pipe passes below the selective catalytic reduction device and is connected to the diesel particulate filter device. A connecting portion for the diesel particulate filter device and the first connecting pipe is located below the diesel particulate filter device.

The invention discloses a quantitative sampling and diluting device and a quantitative sampling and diluting method. The device comprises a sample quantitative extracting component and a sample diluting vessel; the sample quantitative extracting component comprises an upper cover part and a lower sample extracting device which are arranged in a split manner, the lower sample extracting device comprises a capillary and a bearing part used for bearing the capillary, the upper end of the bearing part is buckled with the upper cover part, the lower end of the bearing part is adaptive to an opening end of the sample diluting vessel; the bearing part is provided with a through sampling hole, the upper cover part is provided with an upper cover plug, the shape of the outer wall of the upper cover plug is adaptive to that of the inner wall of the sampling hole; the upper cover plug blocks the sampling hole when the upper end of the bearing part is buckled with the upper cover part; and the capillary is arranged inside the sample diluting vessel through the bearing part. Therefore, a sample is diluted quantitatively, and the quantitative sample can also be moved to a kit to conduct a biochemical reaction.

A system and method for providing access to co-located operations data for a number of electronic display assemblies is provided. A network monitoring center electronically communicates with a number of electronic display assemblies, each comprising sensors measuring operations data, which is stored at a database but electronically partitioned by client identifier. A client identifier is assigned to the operations data. Upon receipt of an operations data request, operations data associated with a client identifier matching a received identifier is summarized in a report which is transmitted to a client device which sent the request.

The present invention provides enamelware and a glaze improving the bondability between the steel substrate and enamel layer and superior in resistance to dew point corrosion by sulfuric acid and hydrochloric acid, that is, a steel substrate of a composition containing, by mass %, Cu: 0.05 to 0.5%, Si: 0.1 to 2.0%, Mn: 0.05 to 2.0%, P: 0.005 to 0.10%, and S: 0.005 to 0.1%, restricting C to C: 0.20% or less, and comprising a balance of Fe and unavoidable impurities on the surface of which an enamel layer of a thickness of 50 to 700 μm is provided. At that time, the content of Co oxides in the enamel layer is made, converted to Co, 0.01 to 10% and / or the content of Ni oxides is made, converted to Ni, 0.05 to 20% or the total content of Ni in the steel substrate and enamel layer is made 0.005 to 4.5% with respect to the total mass of the enamelware and / or the total content of Co is made 0.008 to 4.0% with respect to the total mass of the enamelware.

The invention relates to a furniture unit hinge structure (1) adapted to movably connect a door (102) to a fixed structure (101) of a furniture unit (100), where the fixed structure is located on a support surface (104) and delimits a compartment (103), where the furniture unit hinge structure (1) comprises: a hinge structure fixing portion (2) adapted to be connected to the fixed structure (101); and a hinge structure movable portion (3) adapted to be connected to the door (102), where the hinge structure movable portion (3) is at least rotatably movable relative to the hinge structure fixed portion (2) at least between a first position adapted to open the compartment (103) and a second position adapted to close the compartment (103), where the hinge structure movable portion (3) is movable relative to the hinge structure fixed portion (2) at least between a first position adapted to open the compartment (103) and a second position adapted to close the compartment (103). The furniture unit hinge structure (1) comprises a support foot (4) connected to the hinge structure fixing portion (2), where the support foot (4) is adapted to be located on the support surface (104) to at least directly unload the weight of the door (102) onto the support surface (104).

The invention discloses a connecting structure in a root of a lengthened wind power blade. The connecting structure comprises a blade root connecting cylinder, axial mounting holes, radial mounting holes, double-thread screws and crossed nuts, wherein the axial mounting holes are uniformly and alternately formed in one end plane of the blade root connecting cylinder, the radial mounting holes are circumferentially formed in the wall of the blade root connecting cylinder, the double-thread screws are arranged in the axial mounting holes and the crossed nuts are arranged in the radial mounting holes; the axial mounting holes correspond to the radial mounting holes and are connected with the radial mounting holes to form T-shaped mounting holes, one ends of the double-thread screws protrude into the radial mounting holes to be fastened with the crossed nuts, and the other ends of the double-thread screws protrude out the end plane of the blade root connecting cylinder; the adjacent radial mounting holes are alternately formed in the wall of the blade root connecting cylinder, axial distance from a central axis of every two adjacent radial mounting holes and the end plane of the blade root connecting cylinder is different, and the lengths of the double-thread screws protruding out the blade root connecting cylinder are equal. Under the condition that the number of the radial mounting holes is increased, blade bodies among the radial mounting holes are not likely to be damaged. The invention further provides a mounting method of the lengthened wind power blade.
