bilinear relation

In the yield data acquire multi - line geometric in a radial pattern is adopted . before theoretical explanations about the non - uniqueness of inversions and the necessity of constrains are illustrated , the description of linear travel - time interpolation ( lti ) calculations , the derivation of jacobian linear equations , and the deductions of solving large sparse matrix equations , i . e . the lsqr iterations , are involved . in order to cope with the uncertainties in tomography , we reach several categories on constraint methods
对于野外数据采集采用多测线上放射状布置检波器；围绕层析成像方法，文章分析了线性差值射线追踪lti技术，推导出在矩形网格内速度以双线性关系变化时方程组的解析式，进一步详细探讨方程组的求解方法，即最小平方正交分解法，并给出了迭代公式。
