The analysis showed that both the duration and pressure influenced the SCEP latency,while the duration played a less important role. The SCEP latency was prolonged by 0.300 035 ms after one day compression under constant pressure.

• 压力、压迫时间二者均对SCEP的潜伏期变化相关；压迫时间在回归分析中的作用很小；压力不变的情况下；压迫时间增加1d；SCEP的潜伏期延长0.；000035ms;
