Water is a very good solvent for ionic species . 水对各种离子是非常好的溶剂。
Electrodes measure specific ionic species and not complexes of the species . 电极测定的是特定的离子形式而不是络合形式。
Elemental analysis based on the emission from plasma generated by focusing a powerful laser beam on a solid sample surface is known as laser - induced breakdown spectroscopy ( libs ) . when the power density of laser on the sample surface is high enough , the sample is vaporized , and the neutral and ionic species are formed in excited states 利用聚焦的强激光束入射固体靶表面产生激光等离子体,对等离子体中原子和离子发射谱进行杂质元素分析,这一过程叫做激光诱导击穿谱( laser - inducedbreakdownspectroscopy ) ,简称( libs ) 。
