In this thesis, several kinds of spherical curvature measurement methods are introduced, and the "arch-high and chord-length method" is selected after introduction of the existing methods, and then the novel type of instrument for measuring spherical curvature with the variable ring is developed. In research, the grating sensor, integrated circuits and other new technologies are adopted and integrated. As a result of this, Its specific technical indicator is 0.1um in absolute accuracy, 0.01% in relative accuracy, and 0.001% in repeat accuracy.

本文首先对几种球面曲率半径的测量系统进行了深入的理论分析，在分析了各个测量方法优缺点的基础上，选用了"弓高弦长法"的测量原理，并从理论上推导了本文所述系统的可行性，采用光栅传感器、集成电路等新技术成果，将机械、电子技术、计算机技术以及传感器技术有机结合，研制出一种新型的可变径球面曲率测量仪器。

In spherical polar coordinates, DRSC potential have supersymmetry and shape invariance for θ and r coordinates. By using the method of supersymmetry and shape invariance, exact bound state solutions of Schrodinger equation with double ring-shaped Coulomb potential are presented. The normalized angular wave function expressed in terms of Jacobi polynomials and the normalized radial wave function expressed in terms of the Laguerre polynomials are presented. Energy spectrum equations are obtained.
