中文摘要：

在有各种各样的扎根的电极安排的 Ar 的一口气压血浆喷气(APPJ ) 被采用在 APPJ 的特征上调查电极安排的效果。电、光的方法被用来描绘血浆性质。分别地，关于应用电压的 APPJ 的分泌物模式为 10 公里， 40 公里和 80 公里的扎根的电极位置被学习，主要分泌物和血浆参数被调查。在扎根的电极和高电压的电极之间的远处的增加在分泌物模式和分泌物参数导致一个变化，这被显示出。从让二解除模式，绝缘的障碍分泌物(DBD ) 和喷气的分泌物运输到有三，日冕， DBD 和喷气，随远处从的增加扎根了到高电压的电极。APPJ 的最大的长度在 8 kV 的应用电压到达 3.8 厘米。分泌物力量和转移费用并且光谱为在 APPJ 的种类的线紧张被扎根的电极的位置影响，当在电子的价值没有明显的差别时，为三的激动的温度(EET ) 扎根了电极位置。

英文摘要：

An atmospheric pressure plasma jet（APPJ） in Ar with various grounded electrode arrangements is employed to investigate the effects of electrode arrangement on the characteristics of the APPJ.Electrical and optical methods are used to characterize the plasma properties.The discharge modes of the APPJ with respect to applied voltage are studied for grounded electrode positions of 10 mm,40 mm and 80 mm,respectively,and the main discharge and plasma parameters are investigated.It is shown that an increase in the distance between the grounded electrode and high-voltage electrode results in a change in the discharge modes and discharge parameters.The discharges transit from having two discharge modes,dielectric barrier discharge（DBD） and jet,to having three,corona,DBD and jet,with increase in the distance from the grounded to the high-voltage electrodes.The maximum length of the APPJ reaches 3.8 cm at an applied voltage of 8 kV.The discharge power and transferred charges and spectral line intensities for species in the APPJ are influenced by the positions of the grounded electrode,while there is no obvious difference in the values of the electron excited temperature（EET） for the three grounded electrode positions.
