galvanic coupling meaning in English

电阻耦合

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
铝合金受外力作用，有可能裸露出新鲜金属，新鲜金属与其余已钝化的部分之间，存在耦合作用。
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
耦合状态下，新鲜金属的耦合电位正向移动的速率极快，在40秒钟后已接近于铝合金稳定的自腐蚀电位。
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
再将“耦合作用”的猜想，引入铝合金的腐蚀疲劳裂纹扩展过程中，用电化学的方法测定耦合电流与加载时间的关系，并从理论上导出lc4cs铝合金应力腐蚀裂纹扩展速率的数学表达式，数学模拟的结果与实验值具有较好的一致性。
