  1. In the action of external force, aluminum alloys could bare out fresh metal, so there are galvanic couple between the fresh metal and rest parts passivated

    鋁合金受外力作用，有可能裸露出新鮮金屬，新鮮金屬與其餘已鈍化的部分之間，存在耦合作用。
  2. In the state of galvanic couple, the couple potential of the bare metal quickly shifts towards positive direction, and to approach the stable natural corrosion potential of aluminum alloys after 40 seconds

    耦合狀態下，新鮮金屬的耦合電位正向移動的速率極快，在40秒鐘后已接近於鋁合金穩定的自腐蝕電位。
  3. Furthermore, the supposition of galvanic couple is drawn into the procedure of corrosion fatigue crack growth of aluminum alloys, the relation of couple current vs loading time is determined with electrochemical methods. a formula in the theory is deduced which expresses the stress corrosion crack growth rate of lc4cs aluminum alloy, the results of mathematical modeling preferably correspond with examination

    再將「耦合作用」的猜想，引入鋁合金的腐蝕疲勞裂紋擴展過程中，用電化學的方法測定耦合電流與加載時間的關系，並從理論上導出lc4cs鋁合金應力腐蝕裂紋擴展速率的數學表達式，數學模擬的結果與實驗值具有較好的一致性。
