1·And the depth profile resolution of interface analysis is determined by compromise between the ion mixing and pile up effect.

深度剖面分析的分辨率由离子混合效应和原子堆积效应的折衷结果而决定。

2·Results (1) The spinal cord compression due to degeneration structure in flexion-extension was more significant than that in static position, it even had pile up effect.

结果（1）椎管内退变结构在颈椎伸屈活动时常形成较自然位更加严重的脊髓压迫征象，而且它们间还有“动态叠加作用”。

3·The cooperated mechanism between BT and CTS may be the effect of simple pile up or the effect of releasing slowly.

BT与CTS之间的协同作用机理可能为：简单叠加效应或缓释效应。
