The groundwork of this text is as follows:In understanding the graphic presentation characteristic of the construction drawing of the building, foundation of content. At building the semantemes of construction drawing, building construction drawings understanding tactics and content gone on detailed analysis understanding. Have laid a good foundation for the following understanding of the construction drawing; According to the expression characteristic of the construction drawing, utilize the technology of OOP, Adopt C ++ language and draw the level models of fire control feature; It carries on deep analysis to DXF file format give and a method of read DXF file. On the basis of reading DXF file and familiar with understanding to the form of DXF file, study to the pattern recognition methods of fire control facility.

本文的主要工作如下：在了解建筑工程图的图示特点、内容的基础上，对建筑工程图的语义、理解策略、建筑消防审查等内容进行了详细的分析，为后面的工程图的理解打下了良好的基础；根据工程图的表达特点，利用面向对象的程序设计方法，采用C++语言，得出了消防特征类的层次模型；对DXF文件格式进行深入的分析，并给出了读取DXF文件的方法；在读取DXF文件和对DXF文件的格式熟悉了解的基础上，对消防设施的图形识别方法进行了研究，提出了实效的图形识别的方法。

The operator for detecting selfs and non-selfs on the normal model is proposed, and the operators for recognizing known non-selfs and unknown non-selfs are proposed.

提出了基于正常模型的自体／异体检测算子，提出了已知异体识别算子和未知异体识别算子。

Contrary to the traditional idea, they are unified in this thesis in which the problem of scale in vision and the scale-space representation, the essence of the computation of saliency and the method of recognition based on local invariant feature are discussed.

针对在传统机器视觉研究中，尺度、显著性和物体识别多数被分开研究的现状，本文首先分析了三者之间的内在联系和相互关系，得出应该在一个框架中来研究它们的结论；讨论了视觉中的尺度问题和尺度空间表示方法、显著性度量的计算本质以及基于局部不变性特征的识别方法。

Recognition of character in rubbings is a special application of character recognition.

拓印字符的自动识别是字符识别的一个特殊应用领域，单纯依靠一般的OCR方法不能取得满意的结果。

Furthermore, the algorithm exhibits robuster in the situation that the object is partially occluded, rotated and shape distorted. A vision-based human motion recognition method is introduced in this paper. A modified shape context method named area-based shape context is used to describe the shape. Then continuous hidden markov models are built to model the human motions, and Bayesian criterion is used to classify them.

本文的行为识别算法是建立在对人体行为观测的基础上的，用一种改进的基于人体区域的形状上下文技术表示人体轮廓形状，通过对训练样本集进行学习，利用最佳状态数估计法建立连续隐马尔可夫模型之后，利用贝叶斯判别准则，实现了对人体行为如走、跑、双脚合拢跳跃、单脚跳跃和侧向跳跃五种行为的识别。

Fourier-Mellin transformation was added in the optical joint transform correlator recognition of the rotating and rescaling targets to overcome the low recognition ratio.

针对尺度缩放和角度旋转变化目标相关识别率低的问题，在联合相关识别中加入傅里叶梅林变换方法。

Based on the objective lens and voice coil motor of the current DVD pickup head,according to photobleaching three-dimensional (3D) optical information storage's theory of two-photon absorption,the Ti∶sapphire femtosecond pulse laser was used as written optical beam and reading optical beam of two-photon three-dimensional optical storage voice coil motor was carried through multiplayer choice, and the storage and readout experimental study of binary format code with two-photon photobleaching in the new photobleaching material consisting of stilbene derivant was conducted.

The main contents include: 1 Take high pile and beam bridge for example, this paper discusses the merits and defects of the damage assessment method based on sensitivity analysis...

为 克服灵敏度分析法不能对严重损伤进行识别的缺陷，本文提出用迭代法成功解决了严重损伤的识别问题。

The binding of different halide anions to four strapped calix[4]pyrroles was studied by means of molecular mechanics and molecular dynamics simulations methods. The results indicate that the anion binding ability of calix[4]pyrrole-type systems could be effectively tuned by modifying the length and nature of the bridging straps. In this process, it was the most stable conformation upon anion binding due to the formation of four NH\|halide hydrogen bond, simultaneity, the difference of cavity by modifying straps adapted themselves to different halide anion.

模拟结果表明，加入带状修饰链和调节链长可以增强对某种特殊卤素阴离子的识别，在这个过程中，卤素阴离子与杯[4]吡咯NH上的氢形成的多氢键使主体分子与阴离子形成稳定复合物，同时带状修饰链通过改变杯吡咯空腔大小影响主体分子与卤素阴离子的氢键相互作用，从而调节了对不同阴离子的识别能力。
