METHOD FOR DETERMINING average slope elementary area in the field and profilers FOR ITS IMPLEMENTATION

摘要

1. A method for determining the mean deviation of the elementary area in the field, including the measurement of the surface profile using a profiler, characterized in that, in order to simplify the method and improve the accuracy of determining the average slope of the elementary area is determined surface profile profilograph circumferentially bounding elementary area, build scan this profile and polynomial trend line of the fourth degree by this scan, determine the value of the top point of the polynomial, which conventionally corresponds to a 180 ° position of the roller relative to the zero mark, on which you can analytically calculate the average slope of the elementary area in the field usloviyah.2. Profiler to determine the average elementary area bias field, comprising a frame with three legs, characterized in that, in order to simplify the method and improve the accuracy of determining the average elementary area bias field pivotally-latching axis is provided with ball bearing, on which the Tele shoulder with fixed perpendicularly on the end of the bar, on the bottom of which is attached to the leash in the form of a parallelogram, the roller and a mechanism for reading the vertical displacement of the roller, which consists of the motion sensor, a rigid tape with a longitudinal frame disposed horizontally to transmit only the vertical movement of the roller guide fixed on the bracket and move the sensor, sliding on the surface of a disc rigidly mounted on lockable hinged-axis, the information from the displacement sensors is transmitted to the computer via radio frequency
