stitch spacing meaning in Chinese

线距（缝线距离缝骨边缘的距离）

The in - plane equivalent elastic modulus and tensile strength of stitched composite laminates are studied , and it ' s found that the in - plane equivalent elastic modulus decreases with the increase of stitch density , stitch thread diameter , maximal misalignment angle and the distortion width , and the range is about 5 % . the tensile strength of stitched composite laminate increases with the increase of stitch step and decreases with the stitch space . the
研究结果表明：随着缝纫密度、缝纫线直径、最大纤维偏转角和缝纫变形区宽度的增加，缝纫复合材料层合板面内等效模量逐渐降低，最大降幅一般在5 %左右；缝纫复合材料层合板的拉伸强度随缝纫针距的增加而增大，随缝纫行距的增加而降低，因此缝纫密度对拉伸强度的影响程度要看具体的缝纫针距和行距。
