该系统还在知识库构造阶段引入知识重构机制，对原有的知识库进行精简和重构。

This system also introduces a mechanism for knowledge reconstruction during building knowledge base to refine and restructure the primitive knowledge base building.

目前MRI重构算法只利用MRI图像稀疏性表示或只利用基于其局部光滑性的先验知识，重构效果不理想。

The current MRI reconstruction algorithms simply use either the sparse priors or the local smooth priors of MRI image, and result in the inferior reconstruction.

知识价值、空间整合、空间重构是管理变革的三个侧面。

Knowledge value, space integration and space reconstruction are three aspects of the management transform.
