Compared with the control, the lungs of 3-day-hyperxia-exposure group developed into edema, hemorrhage and inflammatory infiltration and this condition aggravated at the 7th day. The pulmonary septum was significantly widened at the 14th day, the interstitial fibrocytes as well as alveolar epithelial cells proliferated obviously, and the tendency of lung fibrosis was also presented. The results mentioned above showed that the modle of hyperoxia lung injury was successfully established, and the acute inflamationm was its early symptom while the fibrosis was its late manifistation. There was no positive cytes of IFN-γ in the lung of nomal rats, The positive cytes of the groups under hyperxia-exposure for 3, 7, 14 day, which climbed to the climax at the 7th day and began to decline from the 14th day, were found in alveolus epithlia,pulmonary interstitial, bronchoepithlia and macrophage.

高氧14天（5.46±0.30）虽有所下降，但同空气组比，差异仍然具有显著性（P.05）；BALF中蛋白含量高氧3天（0.45±0.10）、7天（0.66±0.08）、14天（0.79±0.14）显著高于空气组（0.18±0.08，P值均。05）；肺通透系数高氧3天（6.61±2.05）、7天（10.88±1.54）、14天（12.75±2.20）均明显高于空气组（2.99±1.27，P值均。05）；同时病理组织学改变也表明与空气组比较，高氧3天时肺组织水肿、出血、炎性细胞浸润，7天时进一步加重，14天时肺间隔明显增宽，间质纤维细胞和肺泡上皮细胞明显增生，出现肺纤维化倾向；以上结果均表明我们成功地建立了高氧肺损伤动物模型，且急性炎症反应是其早期表现，纤维化改变是其晚期表现。

Results:There were luminal dilations of the femoral vein(12.9±2.7mm vs 9.2±2.1mm,P＜0.001)and the popliteal vein(8.8±1,2mm vs 5.9±1.5mm,P＜0.001)in the acute stage of all cases compared to the healthy extremity.There were low echoes in the thrombosed segments by 2D and no blood flow signals by CDFI.

结果：19例急性血栓形成患者入院初诊患肢深静脉内径较健肢明显增宽，股静脉(12.9±2.7)mm vs (9.2±2.1)mm，P＜0.001；静脉(8.8±1.2)mm vs (5.9±1.5)mm，P＜0.001 ，管腔内呈低回声，CDFI未显示血流信号或有血流充盈缺损。

This dissertation gives an alternative way to improve the performance of perovskite manganites by broadening the intrinsic CMR through inducing magnetic inhomogeneity in the material.

The is related to the frequency dependent absorption cross section and the density and spatial distribution of atoms in the lower level of the transition. Position dependent 5P3/2 state densities had been combined with the collisional broadening rate 5P3/2 5S1/2 line due to both helium and cesium perturbers to yield the .The effective radiative rates of the Rb D2 line as a function of the He pressure PHe were obtained . The fluorescence intensity I780 of the 5P3/2 5S1/2 emission was measured simultaneously.

由于辐射陷获存在，有效辐射率是自然辐射率与透射因子（发射的光子在探测区域内没有被吸收的平均概率，它与吸收截面及激发态原子密度和空间分布有关）的乘积。5P3/2原子密度及其空间分布结合5P3/2 5S1/2跃迁线的碰撞增宽计算了透射因子，从而得到了不同He气压下，Rb D2线的有效辐射率。
