Theorem 3. 11 if g is torsion locally nilpotent group and c ( p ) - group, then the nilpotent class of g is at most 3
定理3 11若周期的局部冪零群g是c 」 …卜群，則g的類最多為3 -
So we can easily obtain nilpotent class of s * ( a *, c * ) - groups and the structure of their derived subgroup in the case of torsion and locally nilpotent group
從而進一步得到了周期的局部冪零群的冪零類及導群的結構。 -
In consider drilling rod state, hole state, creep into course influence foundation of parameter synthetically, the drilling rod model under acting on the pulling force and torsion together carries on the theory to calculate, receive drilling rod pulling force and torsion differential equation group, in order to benefit drilling rod strength further to analyse
在綜合考慮鉆桿狀況、鉆孔狀況、鉆進過程參數的影響基礎上，對拉力和扭矩共同作用下的鉆桿模型進行理論計算，得到鉆桿拉力一扭矩微分方程組，以利於鉆桿受力的進一步分析。 -
The biomenchanicai study shows the stress and dispiacement measurements in aht - avb group was iess than in iiiac group and controi group in various modeis such as flex, extension, leff and right bending ( p < 0. 01 ). the torsion stress in both iiiac and aht - avb groups were greater than in control group which indicated a deficiency of anti4orsion ability of aht - avb. with additional anterior piate or pedicle screw, their stabiiity in varies modeis jncluding torsion all increased and greater than in control group
生物力學測試結果顯示人工椎體在屈曲、伸展、左右彎曲、扭轉等工況下應變較對照組及髂骨植骨組小，位移測試結果小於對照組及髂骨植骨組（ p 0 . 01 ） ；髂骨植骨組及人工椎體組在扭轉狀態下其應變及位移均大於對照組，提示旋轉性能不足；附加前路或後路內固定后? ? ? ? ? ? ? ?其各個工況下強度及剛度均明顯增加且均大於對照組。
