3·Just as an acid descaler breaks apart limescale inside a kettle, so the shells that protect molluscs and other creatures will be dissolved.

正如酸性清洁剂溶解水壶内的水垢，保护软体动物和其他生物的外壳也会被酸性海水溶解。

4·Electronic descaler is one that creates a rapidly alternating current in a frequency range that exceeds the best estimate of the internal natural frequency of water.

电子除垢器是一个创建一个迅速交流电的频率范围内，这超过了最乐观的估计内部自然频率的水。
