There were just two problems: it had a lower energy-density than cobalt oxide and suffered from low conductivity, limiting the rate at which energy could be delivered and stored by the battery.
只是存在两个问题：它的储能比钴氧化物要低，而且导电率也较低，这限制了电池释放和存储能量的速度。

The minimum magnetic field intensity needed to induce significant effect on cathodic limiting diffusion current density decreased with increasing ferric ion concentration.
引起极限扩散电流密度明显增加的临界磁场强度随三价铁离子浓度增加而减小。

Phosphorus is the first limiting nutrient density to the algae populations, and therefore control the eutrophication, may depend on the phosphorus control measures.
