The oxidation kinetics of depleted uranium was studied in pure oxygen pressure of 5 kPa at below 100°C by using spectroscopic ellipsometry. The relationship of the thickness of uranium oxide with time is measured. The results indicate that below 100°C in the initial period, the relationship between oxidation layer thickness and time is parabolic. The oxidation mechanism of depleted uranium is discussed and the active energy of depleted uranium at given experimental conditions is 87.165kJ/mol from calculation.

采用椭偏技术研究了45~95℃和5kPa纯氧气氛中金属铀的氧化，通过不同温度下金属铀表面氧化层厚度随时间的变化规律，得到贫铀在初始氧化阶段的表面氧化层厚度与时间的关系均呈现抛物线规律；绘制出了在不同温度下金属铀表面的氧化动力学曲线，由此得到在低于100℃，5kPa的纯氧气氛下贫铀表面形成氧化物的反应活化能为87.165kJ/mol。

Results Nine patients with PTE wore performed thromboembolectomy under cardiopulmonary bypass, one patient was performed thromboembolectomy under non-extracorporeal circlulation. One patient died of pulmonary re-embolism postoperatively, utile patients were survival. There was o marked increase of arterial partial pressure of oxygen and oxygen saturation (P.05) and pulmonary arterial systolic pressure decreased significantly (P.05) at the second postoperative week, with significant improvement in quality of life.

结果 9例在体外循环下行肺动脉取栓术，l例在非体外循环下手术。1例围术期死亡，9例存活；术后2周测不吸氧状态下动脉血氧分压、血氧饱和度均有显著改善，与术前比较有显著性差异(P.05)；术后2周超声心动测肺动脉收缩压显著降低，与术前比较有显著性差异(P.05)，生活质量明显改善。
