The layout of the wires is as follows A, a wire, two wire, wire diagram B, unidirectional traverse, return traverse, polygonal lead; C, closed wire, sympathetic wire, branch conductor D, primary conductor, two stage conductor, three stage guide Line 2. in the following level, the elevation levels of A and B are m HA234. 1，mHB634. 3，the level from P to A, B distance of kmSAP3, kmSBP2二，v i ew The elevation difference is m HAP400. 1二,mhBPOlO. 1, the leveling line is as seen. Is p The elevation is A. 2. 630m, B. 2. 640, m, C. 2. 634m, D. 2. 628m 3, known A 4810. 1013796.972, B 4957.2193588.478, then AB Coordinate increment 二AB alpha . A, 305 Degrees 12 28 ; B, 125, 12 , 28, C, 55, 47, 32 , D, 235, 47 32 4, the use of elevation of 6. 531m level point A, measuring design elevation of 6.800m indoor 0 elevation, level placed in a suitable position, read the level A, the level of reading 1. 035m the aiming level is aiming at the 0 level, and when the readings are, the height of the foot Is the 0 elevation position A, 1. 766, B, 0. 766, C, 0.866, D, 0.666 5, the of adjusting the closing error of traverse coordinate increment is to take the closing difference back symbol . A, according to the average number of angle distribution; B, according to the average distribution of wire edge; C, according to the length of the positive proportion of the distribution of D, according to the length and angle of the average distribution Two. Fill in the blanks 1 cents per room, 20 points 1. The standard square of line alignment Toward,,. 2. The function of the circular level on the level is to make the instrument and pipe level work Use for making instruments. 3, The adjustment of leveling height difference closure is to take the closing difference and its symbol according to each measuring section distribution ratio or by distribution ratio. 4, with level telescope sight on a door and light level ruler, see the image in the eyepiece Is not clear, should spiral, if not clear, should be rotated Screw. 5, the closed traverse, the actual income is not the sum of all the angles of observation is equal to the sum of the
