Abstract: A device for measuring a thermal conductivity of high-temperature and high-pressure liquid is provided and includes a probe and a liquid flow channel, the probe radially penetrates through the liquid flow channel, both ends of the probe extend out of the liquid flow channel and are connected to a control system via wires; the control system includes a power supply, a voltmeter, an ammeter, a thermocouple and a flowmeter, which are used for energizing the probe, measuring voltage at both ends of the probe, measuring current flowing through the probe, measuring temperature of and a flow velocity of the liquid, respectively. A measuring method is further provided. The device and the method for measuring the thermal conductivity of high-temperature and high-pressure liquid utilize a principle of heat balance and characteristics of liquid sweeping across a circular tube for measurement when the liquid enters a fully developed section.

Abstract: The present disclosure discloses a method for automatically identifying south troughs by improved Laplace and relates to the technical field of meteorology. The method includes the following steps: acquiring grid data of a geopotential height field; calculating a gradient field of the geopotential height field in an x direction; searching for a turning point where a gradient value turned from being negative to being positive, and cleaning the gradient field; calculating a divergence of the x direction to obtain an improved Laplacian numerical value L?; performing 0,1 binarization processing on the L? to obtain a black-and-white image and a plurality of targets of potential troughs, merging the black-and-white image and the plurality of targets of the potential troughs by expansion, recovering original scale through erosion, and selecting an effective target through an angle of direction of a contour and an axial ratio.

Abstract: A motion control system including components such as an accelerometer for detecting zero force positions and for self-calibrating the motion control system. The motion control system may be implemented in an active seat suspension.

Abstract: An active suspension system includes a relative slow-responding force bias eliminator (such as a pneumatic actuator) and a relatively fast-responding actuator (such as an electromagnetic actuator) that together support a plant (such as a truck seat or vehicle cabin). The system also includes a load-unload detector (which may be a physical or virtual detector) to detect a loading or unloading of the plant. When such a loading or unloading is detected, the system causes the force bias eliminator to respond quickly (e.g., as quick as possible) while controlling the fast-responding actuator so as to preserve the available energy for operating the actuator (e.g., so as to keep the fast-responding actuator from consuming all of its available energy) prior to when the force bias eliminator can respond.
