Abstract: Disclosed is a method for purifying a nickel-cobalt-manganese leaching solution.

Abstract: A data processing method is provided, which can be applied to calculating a histogram of a preset data sequence. Each piece of data in the preset data sequence comprises an exponential part and a mantissa part. The method comprises: performing normalization processing on the preset data sequence to obtain a first index and a first mantissa of each data; according to the first index and the first mantissa of each data, generating a register address; and according to the register address, adjusting a numerical value in the corresponding register. The data processing method provided by the disclosure can be used in the process of statistical sorting of fixed point non-negative real number data such as ADC sampling data, floating point non-negative real number data such as two-dimensional FFT power data, and other types of data.

Abstract: A nail gun includes: a housing; an accessory box for accommodating a fastener and at least partially connected to the housing; and a power output portion for outputting a striking force to the fastener; and an operating member triggered to have at least a first position and a second position, where the nail gun has a maximum desired penetration depth when the operating member is operated to the first position, and the nail gun has a minimum desired penetration depth when the operating member is operated to the second position; and when the operating member switches from the first position to the second position, an angle by which the operating member rotates about a first straight line is less than or equal to 360°.

Abstract: An assembled subway station and a construction method thereof are provided. The assembled subway station includes a plurality of components combined in a ring shape, comprising a bottom plate component, two bottom corner components, two side wall components, a middle plate component, two top corner components, and a top plate component. Connection surfaces of each component are each provided with a concave-convex structure being matched with another concave-convex structure on a relevant connection surface of an adjacent component. Butt joint positions of two adjacent components are filled with sealing structures. The embedded grooves of two adjacent components are oppositely arranged, and connecting members for exerting opposite fastening forces on the two adjacent components are installed in the oppositely arranged embedded grooves.

Abstract: A lateral double-diffused metal oxide semiconductor field effect transistor (LDMOS), including: a trench gate including a lower part inside a trench and an upper part outside the trench, a length of the lower part in a width direction of a conducting channel being less than that of the upper part, and the lower part extending into a body region and having a depth less than that of the body region; an insulation structure arranged between a drain region and the trench gate and extending downwards into a drift region, a depth of the insulation structure being less than that of the drift region.

Abstract: Techniques are provided for creating mock responses based on default data and mapping actual requests to those mock responses so that a service under test (SUT) may be executed within a simulated integration. In one technique, multiple example requests (ERs) that exemplify actual requests that the SUT may send during a test case are created. Each ER is configured to invoke a downstream service. For each ER, a mock downstream response that is based on default values is created. In a mapping, an association between each ER and its mock downstream response is stored. During the test, the SUT is invoked. Responsively, the SUT generates downstream requests to downstream services, regardless of actual availability. The computer intercepts each invocation of a downstream request. Based on the downstream request, the computer selects a mock downstream response from the mapping and provides the mock downstream response to the SUT.
