置换

During the displacement, the low adsorption methane was always first to be desorbed and the high adsorption CO2 was late to be desorbed. The displacement results under the high pressure is always better than the low pressure.

在置换过程中总是吸附能力弱的甲烷首先解吸，而吸附能力强的二氧化碳最后解吸，而且较高压力下的置换效果总比低压下的好。

This is a report of the results of the clinical application of China-made Austin-Moore artificial femur prothese on 14 cases of femur head and femur upper section desease. Alien bone was used together with artificial femur protheses in two of these cases. Of the 14 cases, 7 were male and 7 female. The oldest was 75, and the youngest 39. The longest follow-up time was 2 years and 3 months, the shortest 5 months. One case died seven months after the operation due to fungus meningitis. One case of ...

本文报告应用国产Austin-Moore型人工股骨头置换股骨头及其上端病变14例，其中二例是人工股骨头加异体骨，男性7例，女性7例，最大年龄75岁，最小年龄39岁，随诊时间最长二年三个月，最短五个月，一例术后七个月，因发生霉菌性脑膜炎死亡，一例系陈旧性股骨颈骨折，因骨折周围软组织挛缩，造成术中安置人工股骨头困难而被迫放弃手术，进行骨牵引，再行第二次置换，随诊结果，功能恢复优者9例，良者2例，差者2例，其中一例术后人工股骨头松动旋转90°，一例失败。
