The main works and contributions achieved in this dissertation are concluded as follows : 1. based on the scalar diffraction theory, the mathematical model of optical configuration of transmissive grating interferometer is established. it indicats that moir interference fringes is affected by many parameters, such as grating pitch, light wavelength, light beam size and incidence angle, etc. the variation that the width, intensity, orientation and contrast of moir interference fringes along with every parameter is numerically analyzed
主要的研究內容和所取得的成果可歸納如下: 1 .基於標量衍射理論，建立了透射式光柵干涉儀光路的數學模型，分析了透射式光柵干涉儀的莫爾干涉條紋與光柵柵距、光柵開口比、光波波長、光斑尺寸、光束入射角等多個參數的關系。 -
The dcb ( double cantilever beam ) met hod to test the interlaminar toughness of fabric - reinforced laminates and the modified compliance calibration method ( mcc ) were adopted in this research. the double cantilever beam ( dcb ) test was executed for stitched laminates to evaluate the interlaminar fracture toughness. the stitch parameters ( stitch line spacing and pitch spacing ) were changed and their effects on interlaminar fracture toughness were examined by means of dcb test by using improved insert type loading fixture
試驗中採用改進的插入型夾具、雙懸臂梁dcb （ doublecantileverbeam ）試驗方法，測試了載荷?試樣開口位移曲線，依據改進的柔度梁方法（ modifiedcompliancecalibrationmethod （ mcc ） ）計算出了各個試樣的層間斷裂韌性（ r曲線）及層間斷裂韌性的平均值，闡明了縫合工藝參數與層間斷裂韌性（ g _ （ ic ） ）間的關系，以拉伸與彎曲強度為約束條件，以層間斷裂韌性值為目標優化了縫合工藝。
