By the EBE strategy and the preconditioned conjugate gradient method (PCG method),we have developed an EBE-subspace iteration for generalized eigenproblems, in which all computations are performed on the element level.

• 本文利用EBE策略和预处理共轭梯度法（PCG法），将广义特征值问题子空间迭代法中各步的计算都单元化，从而避免了总刚度和总质量矩阵的组集，大大节省了存储量。
