A sample processing and analyzing device for soil analysis in a karst area comprises a mounting unit, a processing unit arranged on the mounting unit, and an analyzing unit arranged on the mounting unit and connected with the processing unit through a feeding unit. The design of the damping component can control the grinding force to avoid sample crushing. The installation disc can be effectively clamped by the second axial moving component to move the sample position according to the grinding requirements, facilitating step-by-step polishing. The feeding unit sends the sample to the analysis unit through a conveyor belt for effective analysis. The sample processing and analyzing device can effectively process a soil concretion sample into a sample for analysis, has the advantages of easy operation, high degree of automation and high efficiency, and is suitable for mass popularization.

A sampling device and method for evaluating ecological risk of soil in a high geological background area comprises an impact sampling mechanism, a soil layer stripping mechanism and an auxiliary support frame. The impact sampling mechanism comprises a sampling hopper with a downward opening. A connecting sliding rod is fixedly arranged on the top of the sampling hopper. An upper end of the connecting sliding rod is connected with an impact rod. The impact rod is internally provided with an impact hammer capable of reciprocating along an axis of the impact rod. The soil layer stripping mechanism comprises a stripping sliding cylinder in sliding fit with the connecting sliding rod, and a support disc. A plurality of stripping plates are connected to a lower side edge of the support disc in a sliding fit mode.

A nonlinear disturbance rejection control apparatus and method for electronic throttle control systems are invented to control the electronic throttle system and to achieve a continuous finite-time disturbance rejection control goal. A control sub-apparatus and method are proposed with an observing sub-apparatus and method for controlling the opening angle of an electronic throttle valve. A mathematical model of the electronic throttle system is analyzed and a control-oriented model is presented with the formation of a lumped disturbance. With combination of the continuous terminal sliding mode control method and the output feedback control method, based on the finite-time high-order sliding mode observer, the preferred control performance is guaranteed, where both the dynamic and static performance of the system is effectively improved.

A method () for automatically performing a plurality of image processing functions on an electronic device () by providing a plurality of image processing option keys () including a first image processing option key and a second image processing option key. The first image processing option key is associated with a first image processing function and the second image processing option key is associated with a second image processing function that is different from the first image processing function. The method () performs capturing () a first image using a camera () in response to a user activation of the first image processing option key and then automatically performing () the first image processing function in response to capturing the first image. Next, there is performed a capturing () a second image using the camera () in response to a user activation of the second image processing option key and automatically performing () the second image processing function in response to capturing the second image. Both the first image processing function and the second image processing function are selected from a group of functions.
