中文摘要：

Cu 的敏感的秒衍生物波浪(Ⅱ) ， Pb (Ⅱ) ， Cd (Ⅱ) ， Ni (Ⅱ) ， Zn (Ⅱ) ， Fe (Ⅱ) 和 Mn (Ⅱ) ，在由氨，铵氯化物，明胶和维生素酸组成的底层溶液(pH=9.26 ) 形成被研究。七个离子的 polarographic 波浪的山峰潜力在大约 -0.48,-0.63,-0.79,-1.04,-1.28,-1.44 和 -1.60 V 分别地。与微波技术结合，为在中国传统的药的七个踪迹元素的同时的决心的一个新方法被开发。方法是容易的操作，快速、简单、方便。当 signal-to-noise 率等于 3 时，察觉 Cu 限制， Pb ， Cd ， Ni ， Zn ， Fe 和 Mn 是 4.2 × 10 ~(-3), 5.3 × 10 ~(-3), 2.1 × 10 ~(-3), 5.8 × 10_(-4), 3.0 × 10 ~(-3), 7.7 × 10 ~(-4)和 1.1 × 10 ~(-3) μg /mL 分别地。很好线性的关系在集中和山峰水流之间存在什么时候 Cu ， Pb ， Cd ， Ni ， Zn ， Fe 和 Mn 集中在 8.5 × 以内是 10 ~(-3)-10, 9.7 × 10 ~(-3)-10, 4.5 × 10 ~(-3)-10, 1.2 × 10 ~(-3)-10, 6.4 × 10 ~(-3)-10, 1.5 × 10 ~( -3)-10 和 2.8 × 10 ~(-3)- 10 μg /mL 分别地。方法在鼠尾草植物 Miltiorrhiza 习惯于七个踪迹元素的同时的决心在二药的根和复合鼠尾草植物 Miltiorrhiza 根注射， Cu 的相对标准差( RSD )， Pb ， Cd ， Ni ， Zn ， Fe 和 Mn 是3.9%和5.8%，4.0%和4.1%，4.3%和5.7%，4.9%和5.3%，4.4%和4.7%，3.5%和4.0%，0.51%和2.8%分别地；有标准方法获得的价值的决心结果的比较显示介绍方法有诚实很好。

英文摘要：

The sensitive second derivative waves of Cu（Ⅱ）, Pb（ Ⅱ ）, Cd（ Ⅱ ）, Ni（ Ⅱ ）, Zn（ Ⅱ ）, Fe（ Ⅱ ） and Mn（Ⅱ）, forming in the substrate solution （pH-9.26） consisting of ammonia, ammonium chlorid, gelatin and ascorbic acid were researched. The peak potentials of the polarographic waves of the seven ions are at about -0.48, -0.63, -0.79, -1.04, -1.28, -1.44 and -1.60 V respectively. Combining with microwave technique, a new method for the simultaneous determination of the seven trace elements in Chinese traditional medicine was developed. The method is easy to operate, rapid, simple and convenient. When the signal-to-noise rate equals 3, the detection limits of Cu, Pb, Cd, Ni, Zn, Fe and Mn are 4.2× 10^-3, 5.3× 10^-3, 2.1× 10^-3, 5.8× 10^-4, 3.0× 10^-3, 7.7 × 10-4 and 1.1 × 10^-3 μg/mL respectively. Well linear relationships exist between the concentrations and the peak currents when Cu, Pb, Cd, Ni, Zn, Fe and Mn concentrations are within 8.5× 10^-3 10, 9.7× 10^-3-10, 4.5× 10^-3-10, 1.2× 10^-3-10, 6.4× 10^-3-10, 1.5 × 10^-3 10 and 2.8 × 10^-3-10 μg/mL, respectively. The method has been used to the simultaneous determination of the seven trace elements in Salvia Miltiorrhiza Root and compound Salvia Miltiorrhiza Root injection, the relative standard deviations（RSDs） of the Cu, Pb, Cd, Ni, Zn, Fe and Mn in the two medicines are 3.9% and 5.8%, 4.0% and 4.1%, 4.3% and 5.7%, 4.9% and 5.3%, 4.4% and 4.7%, 3.5% and 4.0%, 0.51% and 2.8%, respectively; the comparisons of the determination results with the values obtained by the standard method indicate that the presented method has very well veracity.
