摘　　要：本文提出的应用阿基米德螺线原理设计的球面曲率计，克服了某些经典仪器需间接换算测量结果的缺陷，其主要优点是能直接读出所测球面的曲率半径和进行连续性测量，在使用上极为方便。这种球面曲率计的设计原理是：将二元函数的理论球径公式变换为一元函数线性公式。This paper presentes the spherometer of designed with the principle of Archimedes spiral, it has main advantage: both continuity measurement and direct reading to curvature radius of sphere, over against some classical instruments requested the conversion of the measuring result. It is convenient in use. The design principle of this spherometer—the authors take the theory equation of sphere curvature radius of binary function to transform into the equation of one—dimensional function, so that we achieve the linear system of measuring reading of this spherometer by use of the characteristic of Archimedes spiral.
