以基准要素模型为扩展基础，为了显式地将时间因素作为第四维度，并满足四维和实时的需求，采用模糊时延Petri网技术对CVE各要素的动态状态变迁进行了良好的描述。
To represent time factor explicitly as fourth dimension and satisfy 4D and real-time requirements , Based on the fundamental part , a Fuzzy-Timing Petri Nets formal modeling technique was employed to expand the fundamental part to describe dynamic state transition of all essential .

对被测要素、基准要素在应用最小实体要求时，尺寸公差与形位公差相互补偿问题进行计算分析。
We calculate and analyze the mutual compensation between size tolerance and form & position tolerance while applying the minimun material requirement to the tested essential factors and standard key elements .
