Abstract: In a cylinder deactivation control method of an engine, a cylinder deactivation trigger moment of a to-be-controlled engine is determined; a second cycle and a cylinder deactivation mode corresponding to the next first cycle are determined according to the crankshaft rotation speed at the cylinder deactivation trigger moment, the target torque at the cylinder deactivation trigger moment, and a second cycle and a cylinder deactivation mode corresponding to the previous first cycle at the cylinder deactivation trigger moment; the fuel injection quantity of the ignition cylinder in the next first cycle is determined.

Abstract: An unloading and collecting device for slice and a cutting machine with the same are provided. The device is configured to collect the slice cut from an end of a silicon rod. The device includes a tray, a box, and a movable assembly, and the movable assembly has a rod member connected to the tray. The rod member drives the tray to adsorb the slice, and the movable assembly is operatable to move the tray in a first direction and a second direction, and to rotate the tray to the box.

Abstract: In a cylinder deactivation control method of an engine, a cylinder deactivation trigger moment of a to-be-controlled engine is determined; a second cycle and a cylinder deactivation mode corresponding to the next first cycle are determined according to the crankshaft rotation speed at the cylinder deactivation trigger moment, the target torque at the cylinder deactivation trigger moment, and a second cycle and a cylinder deactivation mode corresponding to the current first cycle at the cylinder deactivation trigger moment; the cylinder pressure type of each cylinder in the current first cycle is determined in conjunction with the cylinder deactivation modes of three adjacent first cycles; the fuel injection quantity of each ignition cylinder in the current first cycle is determined based on the calibrated preset fuel injection quantity chart of the first cycle.

Abstract: A semi-automatic corrosion box of a copper clad laminate is disclosed. The corrosion device comprises a box body which has no cover; a baffle plate which divides the corrosion box into an upper part and a lower part, wherein a copper clad laminate circuit board is placed on the baffle plate, and a temperature detection module, water pumps and a heating rod are placed on a lower part; and a thermal imaging camera which is placed on a pressing plate through a bracket. Modules in corrosive liquid are connected with an external single chip microcomputer control module through corrosion-resistant wires. The working mode of the present invention is that time and temperature are set with a key matrix at first, and the control module can automatically stop working and enter a low power consumption mode.

Abstract: An online system presenting sponsored content items to users obtains information about quality of the sponsored content items from users to whom the sponsored content items are presented. For example, a user hiding a sponsored content item or reporting a sponsored content item to the online system describe quality of the sponsored content item. By correlating ratings of a sponsored content item by professional raters with a quality ratio of number of reports of the sponsored content item by users to a sum of number of times the sponsored content item was hidden and the number of reports of the sponsored content item, the online system trains a model to determine the quality ratio for sponsored content items based on characteristics of the sponsored content items. When selecting sponsored content items for a user, the online system penalizes or subsidizes a sponsored content item based on its determined quality ratio.

Abstract: The disclosure discloses an integrated automatic sea cucumber cooking and soaking system, which belongs to the technical field of sea cucumber processing.

Abstract: An ultramarine fluorescent protein, is a protein selected from (a) and (b) protein: (a) a protein consisting of an amino acid sequence set forth in SEQ ID:NO. 2; (b) a protein derived from (a) by substitution, deletion or addition with one or more amino acids in the amino acid sequence of (a) and having activity of the ultramarine fluorescent protein. The ultramarine fluorescent protein (UFP) has the characteristics of pH-insensitivity and light stability, and its chromophore can absorb long-wavelength ultraviolet (UVA) and release fluorescence at wavelength longer than 400 nm. And the aromatic amino acids residue (with content of 9.2%) can absorb medium wavelength ultraviolet (UVB) and release UVA.

Abstract: Provided are an enclosed stirrer using intermittent resonance and a method. The enclosed stirrer comprises: two pairs of parallel tension springs (1), a fixing bracket (2), an elastic cantilever beam (3), a cantilever beam pressure clamping device (6), an eccentric motor (4), an arc-shaped cushion block (5), and an enclosed container (8). The enclosed container (8) is mounted on the fixing bracket (2) by the tension spring (1). The elastic cantilever beam (3) is installed below the enclosed container (8) and is axially parallel to the enclosed container (8). One end of the elastic cantilever beam (3) is mounted on the fixing bracket (2) as a clamping end, the other end of the elastic cantilever beam (3) is connected to the eccentric motor (4) as a movable end. The arc-shaped cushion block (5) is connected above the eccentric motor (4). The arc-shaped cushion block (5) reciprocally strikes the bottom of the enclosed container (8) during operation of the eccentric motor (4).
