Results There was no obvious change in the ulstrasonographic characteristics and the pathology of the control group.The diameters,internal echo,the continuity of internal linear echo and epineurium changed correpondingly with time of compression in different model groups.

结果声像图表现：对照组与卡压前正常神经未见明显改变，各卡压组高频超声下均可观察到相应声像图变化，随卡压时间的延长，卡压两端内径逐渐增粗，内部回声逐渐减低，内部线性回声连续性差，神经外膜逐渐增厚。

Electric field distributions and the equation of motion ofthe particles near axis in RFQ Linac are given.

给出了它的近轴区内高频电场的分布及粒子运动方程。

The structure,voltage-dividing theory and design method of the load were presented. The influence of skin effect on the load's resistance in high frequency was analyzed. The distribution of electric-field intensity in the load and vacuum cavity was calculated. The equivalent capacitance and inductance of the load were calculated,of which the influence on the output waveforms was simulated using Pspice program.
