Secondly, paper introduces the composition structure and the manufacture craft characteristic of airplanes, describes the structure and the main assembly process and the assembly characteristic of the n # fuel tank section, points out the assembly accuracy control of the n # fuel tank section. thirdly, paper analyses in detail problems which exist in the current riveted assembly of the n # fuel tank section, proposes the improve measures against the existent problems. finally, paper forecasts in theory the positive effect that the new plan will bring, introduces the practical result after approval test, analyses the differences of both
具體做了以下幾方面工作:第一，詳細闡述了工作研究的基本原理;第二，介紹了飛機的組成結構、飛機製造工藝的特點、 n #油箱段的主要結構、 n #油箱段的主要裝配過程、 n #油箱段的裝配作業特點和n #油箱段的裝配準確度的控制方法;第三，具體分析了n #油箱段鉚接裝配生產線現行作業中存在的問題，針對存在的問題，提出了具體的改進建議，並形成了新的改進方案;第四，從理論上預測了新方案將會帶來的積極效果，介紹了新方案在現場試驗驗證的實際結果，並對兩者之間存在的差異進行了對比分析與研究。 -
The new fuel assembly has very low radioactivity and can be handled and transported safely
未經使用的燃料棒和燃料組件含極低放射性，故在處理和運送方面均屬安全。 -
It is therefore necessary to have an accurate knowledge of low - cycle fatigue ( lcf ) behavior demonstrated by zirconium alloys in order to run the reactor safely, and it becomes in immediate need of the detailed knowledge when the new fuel assembly in request is being developed to reduce the cost of nuclear electricity
因此，要保障核電站水冷動力堆的安全運行，就要對鋯合金的低周疲勞行為有詳盡的了解和認識。特別是當要求研製新型高性能的燃料組件以降低核電成本時，對鋯合金低周疲勞行為的研究就顯得尤為迫切。
