Seismic image filtering machines, systems, program products, and computer implemented methods are provided to generate a filtered seismic image responsive to filtered seismic image data generated by attenuating coherent seismic noise from surface waves of an unfiltered wavefield constructed from unfiltered seismic image data through a single downward extrapolation of the unfiltered wavefield using a plurality of nonstationary convolution operators to perform localized filtering at each of a plurality of spatial locations of the unfiltered wavefield. Various embodiments, for example, can beneficially handle strong lateral velocity variations thus making various embodiments effective tools to remove complicated coherent seismic noise which is typically in the form of exponentially decaying evanescent waves. Embodiments of the present invention, for example, can use, as a part of the filtering mechanism, specially designed nonstationary convolution operators that are implemented in the space-frequency domain as nonstationary filters.

The temperature control circuit and the temperature controller of the electric fryer has advantages of high control sensitivity, precise control of temperature variation, real-time adjustment of the cooking time for the frying food based on that the different temperature variation caused by the different food and quantity, simple operation and high automation.

The invention relates to a method for performing an oil change on a wind power plant, comprising the steps of rotating the rotor (3) to a maintenance position, subsequently draining the oil out of a first variable-speed gearbox (6), filling the first variable-speed gearbox (6) with fresh oil, draining the oil out of a second variable-speed gearbox (6′) that is oriented differently than the first gearbox, and filling the second drive device (6′) with fresh oil. The variable-speed gearboxes each comprise a sump (63) having a first outlet opening (65) and a mirrored sump (64) on the opposite end of the housing thereof having a second outlet opening (66). Thus, the rotor (3) does not need to be rotated further during the oil change. The oil change can be performed simultaneously on several or all variable-speed gearboxes, reducing time and personnel expenses. The invention further relates to a correspondingly designed drive device and to an oil changing device.

The invention provides a fuel nozzle and an engine. The fuel nozzle comprises a shell body and a spraying spout body, wherein the shell body comprises an outlet end, the spraying spout body is installed at the outlet end of the shell body, a spraying spout cavity is formed inside the spraying spout body, the spraying spout cavity comprises a conical section and a spraying-out section, the spraying-out section is connected with the small-diameter end of the conical section, the taper angle of the conical section is an acute angle, and the length of the spraying-out section is larger than 0.2mm. The fuel nozzle enables diesel to meet operation conditions of a turbine engine. When the fuel nozzle is used for the turbine engine, the turbine engine using the diesel operates normally, the turbine engine gets rid of the restriction of aviation kerosene, the combustion application range of the turbine engine is widened, the adaptability of the turbine engine is obviously improved, and oil cost of the turbine engine is correspondingly lowered. Due to the fact that the fuel nozzle enables the fuel oil to be better scattered in an atomization mode, the engine achieves a better combustion effect and increases power output when using the aviation kerosene.

The invention discloses an oil reservoir for heating diesel oil, which comprises a cylinder body, wherein an upper cover is arranged on the upper part of the cylinder body; an oil outlet pipe, an oil suction pipe and an oil return pipe are arranged in the cylinder body; upper ends of the oil outlet pipe, the oil suction pipe and the oil return pipe pass through the upper cover respectively and extend out of the cylinder body; a heating oil pipe is communicated between the upper end of the oil suction pipe and the upper end of the oil return pipe; and a heating device is arranged on the heating oil pipe. When the oil reservoir is arranged, the cylinder body is arranged inside an oil tank, the upper cover and the oil tank are fixedly connected by a connection flange; when the oil reservoir is used in winter, the oil suction pipe sucks diesel oil in the oil tank to the heating oil pipe by an oil pump; and when passing through an exhaust pipe of an engine, the diesel oil is heated by the waste heat of the exhaust pipe of the engine and returns to the cylinder body from the oil return pipe, and the heated diesel oil is conveyed to the engine by the oil outlet pipe, so the wax deposit of the diesel oil is prevented; and due to the adoption of low-grade diesel oil, the cost of the diesel oil is reduced. The oil reservoir can be used in both winter and summer, so the normal running ofdiesel oil vehicles in winter is ensured.
