It was shown that the electrochemical active surface area of the oxide anodes oscillates with IrO 2 content in deposits and decreases with increasing of the preparation temperature.

阳极的电化学活性表面积随涂层中氧化物的成分变化而呈振荡变化；表面活性点数目随制备温度上升而下降。

The decrease of active surface area in the anode caused by CO2 accumulation is reduced through treating the diffusion layer and catalyst layer with PTFE, resulting in increased DMFC performance.

通过对阳极扩散层和催化剂层的疏水处理，降低了阳极产生的CO2导致的催化活性比表面积损失，有效地提高了电池性能。

The most active area of the earth surface is plate boundary, where most earthquakes and volcanic distribute on, while the region within the plate is relatively stable.

板块边界是地球表面最活动的地带，绝大多数地震、火山分布于活动带上，而板块内部则是相对稳定的地区。

Battery efficiency, lifespan and even safety could be vastly improved, the researchers believe, by increasing the surface area of the active materials that make up the battery electrodes.
