编码法 meaning in English
encoding method
Examples
- Secondly , we bring statistic coding , prediction coding , transform coding and analysis & synthesis coding into radar area . according to the properties of radar data , we take 4 methods , which are huffman coding ; prediction error model and lzw coding ; fft , uniform quantization in each frequency bank and huffman coding ; wavelet transform , uniform quantization in each frequency bank and lzw coding , to compress the genuine ground clutter radar data and give the corresponding results
根据雷达回波的特性，分别采用了huffman编码法，预测误差模型和lzw编码法， fft 、分频带均匀量化和huffman编码的压缩算法，小波变换、子带均匀量化和lzw编码的压缩算法等四种算法，并给出了用这些算法对真实的地杂波雷达回波数据进行压缩的实验结果。 - If capp and cam system want to use of these information about a part in cad , they have to transfer these information to proper style , and then they can recognize and use them . these years , there are many researches about how to make full use of the information in cad system and how to describe a part in other systems . during these researches , many methods about part information description have been developed , such as gt code method , language description method , knowledge description method , feature description method , and so on
多年来，为了使capp 、 cam等后续系统能够有效地利用cad系统中相关的零件信息，亦即对零件信息进行合理的描述，人们进行了大量的研究，提出了分类编码法、语言描述法、知识表示描述法、基于形状特征或表面元素的描述法等各种方法对零件信息进行描述，但是，这些方法都需要人来对零件图纸进行识别和分析，即需要人工来对已设计好的零件图进行二次输入，由于输入过程繁琐、费时、易出错，因此这些信息描述方法无法满足信息集成的要求，也不能适应集成环境下capp系统的需要。
