1. The Feature-based Spatio-Temporal Data Model 2. 1 The conception The definition of feature defined by ISO/ TC211 is that the feature exists in two levels: feature type and feature instance.
基于特征的时空数据模型 2。1概念 的定义，功能定义由ISO / TC211是该功能存在于两个层次：功能型和功能实例。
2. With this method, a feature control based adaptive finite dement mesh, by feature definition, search of feature point, line and region, the feature based mesh density control can be realized.
通过特征定义及特征点、线、域搜索，可实现基于特征控制的自适应有限元网格密度分布。
3. I think being bad, is very uhm, is very attractive. An out-and-out baddie is incredibly attractive.
我认为是不好的，非常，嗯，非常的有吸引力。一个彻头彻尾的坏蛋是令人难以置信地吸引人的。
4. Two new flame feature vectors are defined:one is the flame detection context based dynamic feature row and the other is the optimal flame feature area vector.
算法定义了两种新的火焰特征向量：火检上下文动态特征切入列，火焰特征最优区域。
5. Aim at the discrepancy of classified capacity and stability of feature, this paper make use of BP neural net to remark and select above feature, pick out basic feature of cutting tool state.
针对特征分类性能和稳定性的差异，本文采用BP神经网络方法对上述特征进行评价和选择，挑选出刀具切削状态的基础特征。
