转动磁场并不是用机械方法造成的，而是以交流电通于数对电磁铁中，使其磁极性质循环改变，可看作为转动磁场。
Rotating magnetic field is not caused by mechanical methods, but in AC pass in a few of the electromagnet, the nature of its magnetic cycle of change can be seen as rotating magnetic field.
通过选择不同结构、不同碳数的醇做流动相的极性改性剂，优化了色谱分离结果。
The chromatographic conditions were optimized using different alcohols as mobile phase modifier. The effect of temperature on chiral separation was investigated.
