求翻译：PND33悬尾实验HT组静止不动时间较SO组延长，差异有统计学意义（P＜0.01），PND34强迫游泳实验中HT组静止不动时间较SO组延长，差异有统计学意义（P＜0.05）。是什么意思？

stationary time, the pnd33 tail suspension test ht group compared with the so group extended, the difference was statistically significant (p <0.01), pnd34 ht group forced swimming test in stationary than so was prolonged, the difference was statistically significant (p < 0.05).

Over 33 experiments PND tail HT group stationary time extension SO group, the difference is statistically significant ( <0.01 ) and P PND forced swimming test in 34 HT group stationary time extension SO group, the difference is statistically significant ( <0.05 ) P .

PND33 hangs the tail to test the HT group static motionless time to compare the SO group to lengthen, the difference has in statistics significance (P<0.01), PND34 force swimming experiment the HT group static motionless time to compare the SO group to lengthen, the difference has statistics sign

PND33 experiment of cantilever tail HT group group of stationary time was SO extended, the difference statistically significant (P<0.01), PND34 HT group stationary in the forced swimming test time SO groups extend, differences are statistically significant (P<0.05).
