中文版：螺旋面在线计算器
原理：螺旋面参数式 (v·cos u, v·sin u, c·u)，v ∈ [0, R]。第一基本形式 E = 1、F = 0、G = v² + c²，故面积 S = ∫∫√(v² + c²) dv du = πn(R√(R²+c²) + c²·asinh(R/c))。
步骤：输入 R、c、n 后直接代入闭式，并与 GL16 数值积分交叉验证。
示例：R = c = n = 1 时 S = 7.211799724207；c → 0 时退化为 n 个重合圆盘，S → πnR²。
注意事项：螺旋面是与悬链面局部等距的另一个极小曲面（Catengero 定理），但两者的整体面积不能直接画等号；本工具计算的是给定 R、c、n 参数域上的面积。
参考值：S(1,1,1) = 7.211799724207；asinh(1) = 0.881373587020；c→0 极限 = 3.141592653590。
