During operation, the positive rate of patients with increased IMP was significant higher than that of patients without pressure imcreasing(P.01).［Conclusion］The "piston effect" could lead to increased IMP during OIMN of fresh femoral fractures. The increased IMP is an important factor leading to marrow fat intravasation.

结论］股骨骨折早期开放式髓内钉内固定手术中在一定条件下产生的"活塞效应"可使髓内压升高；髓内压升高是股骨骨折早期开放式髓内钉内固定术中导致骨髓脂肪入侵的重要因素。

The results of calibration of 4He in desorption system show that the correlation coefficient is more than 0.99 and the contribution of memory effect can be ignored. The contribution of ionized atom T(superscript +) for partial pressure of m/e=3 is very little and is determined according to I+≈0.01I(subscript T2)+, so the measurement of 3He can be done without interference of T(superscript +). The relationship between gases release rate and annealing temperature can be obtained after the data are smoothed and differentiated.

研究结果表明：四极质谱计标定解吸系统内4He的分压＜350 Pa时，其相关系数R＞0.99，且记忆效应的贡献极弱；离子态氚T对m/e=3组分分压的贡献可按I+≈0.01I(下标 T2)+确定，不干扰3He的测定；将气体解吸所得的积分数据经平滑并微分处理后可准确得到气体释放速率与退火温度的关系，即热解吸谱。
