The large R model is an arc-shaped panel with a short string length, a small string height, and a very small ratio of chord length to radius (generally defined as 1:10). The radius of the profile is relatively large, generally exceeding 1000mm, and some even exceed 2000mm, and the effective length of the effective arc segment does not exceed 100mm. The effective arc of the template is almost straight, and the radius error of the large R template is not allowed to exceed 0.25%, therefore, it is quite difficult to determine the ground radius by measurement. In theory, three points that are not on the same line can determine a circle. Chord long string method is based on this
