feature dependency meaning in Chinese

特征依付

There are many drawbacks in some aspects such as product model editing in the current systems based on process . people study the feature model from managing geometry model elements and put forward the feature model based on cell . in order to overcome those shortcomings and improve modeling ability and efficiency , they apply the feature dependency graph which makes feature modification independent on process tree
同时，将参数化技术引入设计系统中，使得特征具有可调整性，提高了系统设计效率。当前基于历程的特征造型系统在产品模型的可编辑性和易编辑性的技术方面存在许多弊端。为此，从管理几何模型元素这一层次上研究特征模型，提出了基于细胞元的特征模型表示方法。
