摘要：
The present invention relates to an anti-fretting wear spacer grid having a plurality of canoe-shaped springs formed thereon, wherein each of the canoe-shaped springs includes: a fuel rod-contacting part having a flat surface having a predetermined longitudinal length so as to have linear contact with the fuel rod; a curved face-connecting part formed on the upper and lower portions of the fuel rod-contacting part; a leg-connecting part formed on the end portion of the curved face-connecting part; and legs each being formed of a plate shape having a predetermined length and connecting the both sides of the leg-connecting part with one unit grid cell surface.
摘要（中）：
本发明涉及一种具有形成在其上的多个独木舟形弹簧的抗微动磨损间隔栅格，其中每个独木舟形弹簧包括：具有预定纵向长度的平坦表面的燃料棒接触部分， 与燃料棒线性接触; 形成在所述燃料棒接触部的上部和下部的弯曲面连接部; 形成在曲面连接部的端部上的腿连接部; 并且每个腿均由具有预定长度的板形形成，并且将腿连接部分的两侧与一个单元格格单元表面相连。
