Embodiment Construction
[0012] figure 1 An example of the present invention is given. figure 1 In this method, two glass tubes with round mouths at one end are used to cover the glass tube 1 and the inner glass tube 2 in a concentric nesting arrangement, and the outer surface of the inner glass tube 2 is made of a selective absorption film by vacuum sputtering, and at the openings of the two glass tubes 1 and 2 Melting and forming a vacuum between the two layers of glass tubes to form a vacuum heat collecting tube with corner scale marks. The corner scale bar mark 3 uniformly distributed according to the 360-degree circumferential angle is formed by not coating the outer surface area of the inner glass tube 2 to form chromatic aberration. The end point 4 of part of the bar mark 3 is marked with a text corner scale mark. Usually these words are 4, 7, 10, 1, can formulate standard regulation: in 4, 7, 10, January, make 4, 7, 10, 1 be at the topmost of heat collecting tube. The surface of the coati...
