軟相鄰層 的英文怎麼說
中文拼音 [ruǎnxiānglīncéng]
軟相鄰層
英文
soft adjacent layer (sal)-
This paper describes an aag ( attributed adjacency garaph ) based method of machining features recognition for shaft kind parts and 2. 5d parts on the acis platform, which can effectively recognize the main and assistant feature of these kinds of parts. using the class library provided by acis, all the geometrical information for defining a feature can be acquired. finally a xml neutral file describing the recognition result is provided for the later capp process and the generation of nc code
本文首先分析三維實體邊界模型的特徵識別方法及其特點,繼而採用基於屬性鄰接圖的特徵識別方法,研究了軸類零件及2 . 5維零件的加工特徵的分類及其識別,並在acis平臺上開發了相應的軟體原型系統,有效地識別該類零件的主特徵和常見的輔助特徵,且利用acis提供的類庫介面提取模型底層的幾何參數,得到定義各項特徵所需的幾何尺寸信息,最後以xml中性文件的形式輸出識別結果,為后續進行的工藝規劃、加工代碼生成提供初始數據,從而為cad / capp / cam的集成提供有效的方法。Based on development platform and the software designing, we develop a self - governed and perfect database system for surface wave tomography in china and its adjacent land and sea areas. this database system is helpful and important for probing into the deep earth, the form and evolvement of lithosphere / asthenosphere, the form and evolvement and the relation of surface structure and deep structure of chinese continent
為對這些海量數據進行合理有效管理,作者採用發展較成熟的開發平臺和軟體設計方法,開發一個獨立、功能完善的「中國及相鄰陸域海域面波層析成像數據庫系統」 ,對研究地球深部過程,對了解中國及鄰區邊緣海巖石圈軟流圈形成及演化,了解中國大陸形成及演化以及地表構造與深部結構的關系都具有極大幫助和重要的意義。
