A surface texture measuring instrument includes a contact piece to be in contact with an object, a sensor driving mechanism that moves the contact piece along the surface of the object, a controller that controls the sensor mechanism, and a force sensor that detects a measuring force exerted on the contact piece when the contact piece is brought into contact with the object. The controller includes a target value output that outputs a target value of the measuring force, a feedback controller that performs feedback control of the sensor driving mechanism based on a deviation between the measuring force and the target value, and a feedback compensator provided on the feedback controller. The feedback compensator performs feedback compensation in accordance with the measuring force.

Geophysical exploration for oil wells, the source from the vertical seismic profile aspect wave data stack depth domain Corridor profile approach is the use of in situ collection of well spacing VSP data, which will all receive points drilling depth of information and hierarchical data with the depth of information, the use of direct wave VSP data travel through and optimization algorithms are highly accurate anti-layer velocity model, the direct wave to the beginning of the reflected wave in the vicinity of the depth and precision homing imaging, further in-depth domain Corridor section and with the superposition of alternative conventional method leveled in the time domain, with corridors and the superposition method, the results can be superimposed for direct comparison with the drilling and seismic data stratified layer identification. More intuitive, but also made full use of VSP data in the depth of information, make geological formation of the earthquake response and drilling, logging data in depth domain direct contrast, a more intuitive geological layer and the relationship between seismic horizon, thereby enabling layer of identification and calibration more reliable.

The invention discloses a control device and a control method for automatic deployment of an oil spill boom on the sea surface, which includes a programmable controller, and the control device includes a first hydraulic motor and a second hydraulic motor, and the programmable controller The first proportional amplifier is connected to the first proportional valve, the first proportional valve is connected to the first hydraulic motor, and the first hydraulic motor is connected to the first reducer; the programmable controller is connected to the second proportional valve through the second proportional amplifier. The valves are connected, the second proportional valve is connected with the second hydraulic motor, and the second hydraulic motor is connected with the second reducer; and its control method. Using the same control method can greatly reduce the influence of the uneven force on the system of the two motors, improve the anti-interference ability of the system, and finally realize the purpose of a certain proportional relationship between the speed of the two hydraulic motors with uneven force, and realize the two Under the same control mode, the speed of the motor is coordinated and controlled, which improves the automation level and control accuracy of the system.
