The present disclosure discloses a method for assessing soil health of cultivated land, which adopts 'three sets of dual index assessment systems', that is an index system for current soil function and a healthy soil function required by crops, an index system for current soil nutrition and healthy soil nutrition required by crops, and an index system for current crop output of cultivated land and a crop output expected by cultivated land users or owners. The method solves the shortcomings of the existing assessment systems that the existing soil health assessment index system has no hierarchy and applicability. This method includes using deviating degree of ratio R e.g., the index current value C/index health value E of measured dual index from 1 as well as it is simple, and the assessment result may directly determine the indicators or factors that can be used for guiding soil improvement and conservation.

A brake assembly includes: a motor rotor; a brake disc fixed on the motor rotor; a friction plate fixed to and surrounding the brake disc; a bearing rotatably sleeved on the motor rotor; an electromagnet assembly fixed on the bearing; a baffle plate fixed to the electromagnet assembly; an armature slidably sleeved on the motor rotor, and located between the baffle plate and the electromagnet assembly; and a spring assembly provided between the armature and the electromagnet assembly. When the electromagnet assembly is de-energized, the armature is pushed by the spring assembly to move in a direction close to the baffle plate, such that the friction plate is clamped by the armature and the baffle plate to realize braking.

Laser ablation processing method for debris-free and efficient removal of materials comprises the step of using a refrigeration device to condense the water vapor and form a thin frost layer on the materials at temperatures below the freezing point. The residual debris produced during the ablation process deposits on the frost layer that covers the material, which is easily removed when the frost layer melts. At the same time, the frost layer in the laser irradiation area melts to a liquid layer, which can effectively reduce the deposition of debris on the inner wall of the groove and thus improve the efficiency and quality of laser ablation. The method is applicable to debris-free laser processing on an arbitrary curved surface.

Methods, apparatus and articles of manufacture (e.g., physical storage media) to calibrate interpolating string digital-to-analog converters are disclosed. Example methods disclosed herein to calibrate a digital-to-analog converter (DAC) include determining a first calibration codeword based on a first nonlinearity error value measured at an output of the DAC when a most-significant-bit (MSB) portion of an input codeword is applied to an input of the DAC. Such disclosed example methods also include determining a second calibration codeword based on a second measured nonlinearity error value measured at the output of the DAC when a least-significant-bit (LSB) portion of the input codeword is applied to the input of the DAC. Such disclosed example methods further include combining the first calibration codeword and the second calibration codeword to determine a third calibration codeword to be accessed by the DAC to calibrate the output of the DAC when the input codeword is applied to the DAC.
