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。

Kanic acid was injected into guinea pigs' cochleae and the excitotoxicity model was established. After a week the recombinant plasmid was transferred into SGCs of guinea pigs' cochlea treated with HAT. The following week the expression of NT-3 was examined by the immunohistochemical method, and the morphology of SGNs was observed under the electronic microscope after 4 weeks, in the mean time the changes of auditory brain-stein response were examined.
