研究结果表明，铂电极上线性碳酸酯DEC、DMC和EMC的阴极还原极类似，而环状碳酸酯PC较线性碳酸酯难还原；

On platinum electrode, linear carbonate DEC, DMC and EMC have similar cathodic reduction behavior, but ring carbonate PC has lower cathodic currents than linear carbonates.

因此，本论文主要在超临界二氧化碳中进行了以下两部分工作：一是利用二氧化碳合成环状碳酸酯；二是利用二氧化碳合成恶唑烷酮。

Hence, two parts of researches were carried out under supercritical carbon dioxide in this paper, including the synthesis of cyclic carbonates and the synthesis of oxazolidinones.

在其内外层，分别还有导电材料制成的环状物，充当两个电极。最外层则是另一层聚碳酸酯的表面。

This is sandwiched between inner and outer rings of a conducting material that act like electrodes, and surrounded by yet another layer of polycarbonate as cladding.
