1、Melamine peaks meeting the retention time and ion ratio criteria must be compared to the positive tissue control.───即使三聚氰胺的保留时间和离子比符合检出标准也必须和阳性对照样品进行比较。
2、PTFE membrane was more hydrophobic than PVDF membrane, PTFE membrane employed in the treatment of phenol aqueous solution had a better efficiency and a higher ion rejection ratio.───PTFE膜的疏水性较PV DF膜强，在相同进料条件下，用PTFE膜处理含酚水溶液的分离效率和离子截留率更高。
3、That's shifted in recent years to lithium-ion batteries, which can be made much smaller, with a superior weight-to-energy ratio.───近几年转向了锂离子电池，可以做的小很多，有着超高的重量能量比。
4、Melamine peaks meeting the retention time and ion ratio criteria must be compared to the positive tissue control.───聚氰胺的保留时间和离子比符合检出标准也必须和阳性对照样品进行比较。
5、We developed an ion beam source. The atomic ion ratio is higher than 99%, much higher than commercial ion sources.───我们自行研制的离子束源，其原子离子的比例大于99%，远高于商用离子源。
