A global crack - line displacement fitting procedure ( gcdfp ) for computing stress intensity factors ( sif ) has been developed. the precision of sif is compatible with the corresponding cod data
使用paris公式求出裂紋前緣各點的裂紋擴展增量，並用三次b -樣條函數對這些增量進行擬合，得到新的光滑裂紋前緣。 -
This method utilizes an on - line algorithm based upon lssvm ( least square support vector machine ), which can build adaptive models to predict the cod values of unknown water samples quickly and accurately. in the modeling process, every training sample is also assigned a prior weight to take their significance to the final predictive model into account
該方法是一種基於最小二乘支持向量機的在線自適應加權演算法，這種演算法可以自適應地選取和未知水樣最相近的標準樣本進行建模，同時在建模中又利用加權的方法分別考慮了各個標準樣本重要性。 -
