Plant cytoplasm velamen H + & ATPase ( EC3.6.1.35 ) is an inserted protein on the velamen . It can produce energy by hydrolytic ATP and pump out H + at the inner side of velamen so it is called protonic pump .

植物细胞质膜 H~+&ATPase（EC3.6.1.35）是质膜上的插入蛋白，具有利用水解ATP产生的能量，将细胞质膜内侧的H~+泵到质膜外侧的特征，简称为质子泵。

The traditional measuring method is that passing a large current through contacts so that velamen resistance is eliminated then contact resistance is nothing but contraction resistance .

传统的检测方法是让 触点 接通一个较大的电流，以消除 薄膜电阻，此时触点的接触电阻即为收缩电阻。

The contact resistance between contacts is composed of contraction resistance and velamen resistance .

电器触点间的接触电阻包括收缩电阻和 薄膜电阻。
