Unlike manganese nodules, which are like golf balls scattered across the seabed, these deep - ocean deposits occur in small areas around extinct hydrothermal vents

核不同，
錳結
核就像高爾夫球洞一樣分散地分佈在海底，而這些深海礦物層則在熄滅了的海底煙囪附近的小范圍內存在。
When subjected to such process, the steel surface will be covered with numerous fine manganese - phosphate crystals so that the crystal nucleus necessary for manganese - based phosphorizing increases greatly in number. this may not only accelerate phosphorization and properly lower the temperature of phosphorization, but also prevent big - size crystals from being generated. as a result, the resulting phosphate has improved fineness and evenness
鋼鐵經它處理后，會在其表面覆蓋上許多極細小的錳磷酸鹽結晶，使錳系磷化所需晶核數目大為增加，以而加速磷化反應速度，並能適當降低磷化溫度，還可以阻止粗大結晶的生成，因此形成的磷化膜更加均勻細致。
