摘要
介绍了采用双三次均匀B样条曲面法构造星孔装药燃面退移图象中，夹直纹面的曲面；具有脊线曲面的反算拟合；燃面拟合的边界条件及曲面加密网格的求解等特殊问题。
Spectial problems of constituting curves and curved surface of burning surface regression of star perforation grains with cubic uniform B-spline and bicubic uniform B-spline are introduced.These problems include reverse calculation fitting of straight grain surface between curved surface and curved surface with ridge line, border condition of the burning surface fitting and calculation of the burning surface with additional dense net.
