The findings indicate that, on the whole, the pattern of load transfer curves of adfreezing stress on a steel pipe pile stem and that of resistance stress on the pile tip are parabola and straight line, respectively; Due to the rheology effect, to different extent, adfreezing stress on the pile stem and resistance stress on the pile tip vary with time and relative displacement of pile-soil, respectively, and the settlement of pile tip varies with time tempestuously within 5 hours of loading, and then approximates to stability.

结果表明：模型钢管桩桩侧冻结力荷载传递函数曲线及桩端阻力荷载传递函数曲线其线状大致分别程抛物线及直线；由于流变效应的影响，桩侧冻结应力及端阻应力随时间有不同程度的变化；桩土相对位移和桩端下沉量开始5h内随时间变化较大，但加载5h后逐渐向稳定方向发展。

Since the infant CPB needn't high flow rate, the 12mm pitch wheel with higher anti-resistance ability is more suitable in this study;(3) The axial flow pump with 12mm pitch wheel was used in animal experiment.

考虑幼婴儿体外循环中对流量的要求不高，因此抗阻能力较高的螺距12mm的叶轮更适合本设计的要求；（3）在动物实验中选用12mm螺距的叶轮安装在轴流泵中。

Methods 79 cases of chronic respiratory failure were divided into 2 groups randomly: control group (34 cases) were given general treatment, including anti－ inflammatory, antitussive, apophlegmatic, cardiac tonic, diuretic agents, et al; solcoseryl group received solcoseyl for 14 days besides general treatment. Hemorheologic indexes of both groups were detected before and after therapy.

79例慢阻肺、肺心病发展而来的慢性呼衰病人随机分为两组：对照组 34例，予以抗炎、止咳化痰、强心利尿、改善心肺功能的综合治疗；治疗组在综合治疗基础上予以血活素 15ml＋生理盐水 200ml，静滴，疗程 14天，两组在治疗前后测定血液流变学指标（包括高低切全血粘度，红细胞变形指数及电泳时间，血小板粘附率等）。

Results An intracerebral echoless cyst could be visualized in all the three cases, in which" high-speed and low-resistance" blood signal could be detected by CDFI. There was direct communication between the vein of Galen and several basis cranii cerebral arteries without cerebral ventricle dilation. The dilated heart-breast rate could be visualized in all the three cases, two of which complicating with the dilation of superior vena cava and tricuspid regurgitation; two of which complicating with pleural fluid and abdominal dropsy; one of which complicating with edema of skin and polyhydramnios; one of which complicating with reversing blood signal of umbilical artery in diastolic phase.
