It is found thatthere exist three modes in a magnetized, homogeneous, and collisional dusty plasma:the wholly damped mode due to the thermal diffusion, damped electrostatic dustacoustic wave, and damped electrostatic dust cyclotron wavediscovered by the dissertation for the first time; As neutral gas pressure increases,the damping rates of the EDA and EDC waves increase; The effects of dust densityon the EDA and EDC waves are remarkably different from unmagnetized orcollisionless plasma; A possible explanation to plasma crystallization is suggestedon the basis of the present results.

EDA的阻尼速度随中性气体压强的增大而增大，这一点与实验相符，对于EDC也存在同样的关系。尘粒密度对EDA波和EDC波的影响明显不同于非磁化或者无碰撞尘埃等离子体中的情况。当忽略碰撞时，阻尼的EDA和EDC波回到纯振荡波。最后就尘埃等离子体晶化给出了一个可能的解释。

The results show that photocatalyst TiO2 improves the removal rate of toluene in not only the nitrogen plasma field (NTP-P-O2/N2) eradiating ultraviolet light but also the argon plasma field eradiating visible light. This supports the idea that both the UV light and the high-energy electron in the plasma field can activate TiO2. Furthermore, the toluene removal rate in NTP-P-Ar system is 5% higher than that in NTP-P-O2/N2 system, confirming that high-energy electron has greater effect on the degradation performance of toluene, as compared with UV light.

结果表明：在发射紫外光的氮等离子体场(NTP-P-O2/N2)中和发射可见光的氩等离子体场中，TiO2：均能提高体系的甲苯去除率，说明等离子体场中产生的紫外光和高能电子均能激活光催化剂TiO2；NTP-P-Ar体系中的甲苯去除率较NTP-P-O2/N2：体系中的约提高5%，说明等离子体场中高能粒子对甲苯降解性能的影响要强于紫外光的影响。
