  集总质量矩阵
• Using the approximation form of lumped mass matrix instead of the mass matrix in finite element discretization in space , backward differencing scheme in time , an implicit computational scheme is yielded , it proved the convergence estimate for this implicit scheme
  对有限元离散中引起较大误差的质量矩阵，采用了近似形式的集总质量矩阵来代替，时间项采用向后差分，得到了一个隐式的计算格式，证明了计算格式的收敛性及其收敛速度估计。
