When the Rotary cutting Drum for mining Cobalt-rich Crust is working on the fluctuant microtopography of sea floor, it's necessary to determine the cutting depth according to the mining requirement.

用滚筒式采矿头在起伏不定的微地形上切削海底富钴结壳时，需按开采要求确定其切削厚度。

Based on some experts' forecast, in the middle of this century cobalt crust 's commercial and comical mining would be possible.

根据专家预测，本世纪中叶就有可能进入钴结壳商业开采的阶段。

The modeling and analysis in this paper will supply some important reference to detecting the depth of the cobalt-rich crust and the fluctuant Microtopography of the cobalt crust.

此问题的建模对于钴结壳的厚度检测，及微地形起伏的检测等也有重要的指导意义。
