Embodiment Construction
[0013] exist figure 2 In , the glass ring (2) is fixed by the fixed snap ring (1) and the upper glass cover slip (not shown).
[0014] The method of measuring the inclination or slope angle: After measuring the inclination of the rock formation, turn the compass 90 degrees, and use the buoyancy of the hexyl ether in the glass tube to the bubble (the bubble always stays at the vertical top of the ring) to take a direct reading instead of The long level needs to be adjusted like a current compass. When reading, you can take the tangent reading x between the bubble and the scale line. Assuming that the bubble diameter corresponds to a scale value of 4 divisions, then the inclination or slope angle α=x±4 / 2=(x±2)°, that is, the reading x is the bubble and scale When the smaller value of the line tangent, α=x+4 / 2=(x+2)°, on the contrary, α=x-4 / 2=(x-2)°.
