嵌套错误 meaning in Chinese

nesting error

The historical development of bom technique is reviewed from theory and practice , and the analysis , design and optimization strategy of relational database based bom are presented . in the flowing section , the paper analyzes traditional bom search algorithms and proposes some optimization algorithms , and then , through applying dag to bom technique , the bom cyclic nesting error check algorithms and low - lever code algorithms are improved as well
本文重点研究了bom技术的研究现状，提出了基于关系型数据库的bom的分析、设计和优化策略；并且对bom的常用遍历算法进行分析后对其进行改进；将dag图运用到bom技术上对bom的循环嵌套错误检查的算法和低层码的算法进行改进。
