  1. Uniform carburized layer

    均質滲碳層
  2. The metal carburized layer depth is one of the major technical parameter to evaluate the quality of carburized components

    滲碳層深度是衡量滲碳件質量的主要技術指標之一。
  3. However, many factors may affect eddy current testing and it is hard to classify them, and how to extract information which indicating carburized layer depth in signals is very important

    但影響渦流檢測的因素很多，檢測結果不盡如人意，如何提取信號中的反映滲碳層深度的信息非常重要。
  4. Abstract : the effect of different carburizing programs on the microstructure and thick of carburized layer of screw bevel gears has been studied, meanwhile the fatigue life of these gears has also tested

    文摘:本文研究了不同滲碳淬火工藝對螺傘齒輪組織及滲層深度等影響，並對螺傘齒輪進行了臺架疲勞測試。
  5. This paper is introduced bp neutral network character, algorithm, designing principal on its construction and the designed product. input features extracted by the way described above into a bp neutral network, and using it to classify seven type of different carburized layer depth specimen. the result is indicated, using wavelet packet method to extract features and bp neutral network to classifying, is effective and precise to classify different metal carburized layer depth. it is useful and economical

    本文介紹了bp神經網路的特點、演算法和其結構的具體設計方法和設計結果，並將小波包提取的特徵值輸入到bp網路，對7種不同滲碳層深度的試件進行分類，實驗結果表明，小波特徵值提取和bp神經網路分類器相結合，可以實現對不同滲碳層深度的分類，效果良好，精度較高，有一定的實用價值。
  6. Eddy current testing is a method suitable for testing changes occurred in the surface or subsurface of specimen. when using this method to test carburized components, the variable of eddy current signal is depend on the change of constituents " physical property in carburized layer. so it can be used to test carburized components nondestructively

    渦流檢測是一種適用於試件表面和近表面變化的檢測方法，利用渦流方法檢測滲碳件時，渦流檢測信號的變化主要取決于滲碳層組織的物理特性的變化，所以渦流檢測方法可以對金屬表面滲碳層深度進行檢測而不構成任何破壞。
