Similarly, when a pipeline transverses moist clay areas adjacent to dry loam, steel surfaces in the wet area become anodic to steel surfaces in the dry area.
与此相似，当管道通过与干亚粘土接壤的湿粘土区时，湿粘土区钢表面相对于干土区钢表面为阳极。

The intimate contact of two surfaces to be bonded is a prerequisite for the anodic bonding, therefore, it is very important to analyze evolution characters of the intimate contact area.
待连接表面间的紧密接触是实现阳极连接的必要条件，因此分析紧密接触面积演化特点非常重要。

Various measures were taken depending on whether acid circulated or not to keep the acid cooler in the safe area of anodic protection with a stable passive film and thereby lone service life.
