Claim 0:
1. A method for measuring a shortest distance between two adjacent capacitances, comprising: obtaining a distance between tangent lines of adjacent surfaces of the two adjacent capacitances, and taking the distance between the tangent lines of the adjacent surfaces of the two adjacent capacitances as the shortest distance between the two adjacent capacitances, wherein the tangent lines of the adjacent surfaces of the two adjacent capacitances have a same direction, and the direction of the tangent lines is perpendicular to a preset arrangement direction of the two adjacent capacitances;
wherein a distance between the tangent lines of the adjacent surfaces of the two adjacent capacitances in the preset arrangement direction is used as the shortest distance between the two adjacent capacitances, the two adjacent capacitances are columnar capacitances, and the tangent lines are tangent lines of cross sections of the two adjacent capacitances;
wherein obtaining the distance between the tangent lines of the adjacent surfaces of the two adjacent capacitances further comprises:
obtaining radiuses of the two adjacent capacitances; obtaining a distance between two straight lines that pass through circle centers of the two adjacent capacitances respectively, wherein the two straight lines have a same extending direction as the tangent lines; and taking a difference of the distance between the two straight lines and a sum of the radiuses of the two adjacent capacitances as the distance between the tangent lines;
or
obtaining diameters of the two adjacent capacitances; obtaining a distance between first tangent lines of non-adjacent surfaces of the two adjacent capacitances, the first tangent lines have a same extending direction as the tangent lines of the adjacent surfaces of the two adjacent capacitances; and obtaining a difference value of the distance between the first tangent lines and a sum of the diameters of the two adjacent capacitances, the difference value being taken as the shortest distance between the two adjacent capacitances.
