The first feature of the model is the essence of each helix transformation; the second feature of this model is the inter-impact among these triple helixes; the third feature is the triple network and the re-superposition generated from the interaction among these triple dimensions.

为此，本论文得出以下几个方面的结论：(1)政府、产业和大学&三重螺旋&是一个创新模式，这一模式抓住了在知识资本化进程中，不同阶段制度安排的多元互惠关系。

Aiming at the leakage for the security of PCA, a secure face recognition algorithm was proposed, based on adaptive non-funiform quantization which quantizes the template feature obtained by PCA and stores the hash value of the quantization feature instead of the template feature.

分析了主成份分析方法的安全性，针对其存在的安全漏洞，提出了一种基于自适应非均匀量化的安全人脸识别算法，将主成份分析方法得到的人脸模板特征进行量化，用量化特征的哈希值代替人脸模板特征存储在数据库中，并给出了该算法的安全性分析。

Defines a conditional default value for a feature; the condition is specified as a feature structure, and is met if it subsumes the feature structure in the text for which a default value is sought.

定义一个功能的条件预设值；该条件被指明为一个功能结构，且若在需要预设值的文本中包含该功能结构时，则表示条件符合。

This dissertation brings forward and realizes one method of establishment of handwritten Chinese character library on account of feature of characters' shape: first, scan the characters wrote on paper to the image file, then break up the whole piece of characters image to solo character, and do some feature extraction. After this, pick up the feature of the image and write in file supervened.

本文提出并实现了基于字形特征的手写体汉字字库的构建方法：先将在纸上书写出的字符扫描成图像文件，然后对整幅的字符图像进行分割，将其分割成一个个的字符，再对图像进行一系列的预处理，接着抽取图像特征，写入文件。

Aiming at feature point based image registration, we suggest the concepts of broad sense feature point and narrow sense feature point.

针对基于特征点的图像配准，本文提出了一种基于广义特征点的图像自动配准方法。

For enhancing the system performance, the simple bit-wise indexing method was applied to the manufacturing defect detection problem, time aspect for manufacturing domains. For improving the flexibility and accuracy, the encapsulated bit-wise indexing method is applied to the pattern matching module of an Internet intrusion detection system. To reduce the processing time, the compacted bit-wise indexing method is applied to the data-driven rough-set based feature selection. Additionally, the proposed feature selection method was adopted in a KA project to discover the desired feature sets to construct a CBR system for a world-wide financial group customer relationship management system's loan promotion function.

For the 3D human body and garment modeling and surface fitting, a human body database and a three-layer feature model are set up based on the human body measurement data. The class inheritance relations of human body are established according to three-layer feature model: object layer, feature layer and geometry layer.

对于三维人体和服装的建模与曲面拟合，设计了基于人体采集数据的人体数据库，建立了人体的对象层、特征层与几何层三层特征模型，并结合三层特征模型建立了人体类的继承关系。

While only first-order gradient feature (denoted by 1) and the feature used in SRNE (denoted by 12) yield results with obvious jagged staircase effect in the constant color region and NEVPM yields results with noisy edges and blur, the proposed improved feature combination with a (13al) preserves sharper edges and shapes and suppress blocky artifacts such as the edges of goblet and book.

仅当第一顺序梯度特征（表示1）和用于在连续色彩区域中其结果明显带有锯齿状阶梯形的SRNE的特征（表示12），以及用于结果带有边缘和污点干扰的NEVPM的特征，被提议的改进的特征组合a（13al）保留了较锋利的边缘和外形以及人为控制的块状，比如酒杯和书的边缘。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
