Comparison between the velocity distributions at the different flow rate conditions showed that increasing the flow rate was help to improving the velocity distribution. The periodic mean field on r-6 plane at different axis positions showed that the flow within the vaned diffuser, especially within the inlet region, was periodic unsteady when impeller located at the different circumferential position, just as the flow within the vaneless diffuser.

有叶扩压器内平均流场的分析表明，在定常流动的假设下，不同流量工况下有叶扩压器的内部流动也呈现为沿轴线向后盘方向推移流动状况逐渐恶劣的分布规律，表明二元叶片构成的平行直壁有叶扩压器对轴向不均匀流动的掺混作用仍然不大。

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。

Methods Undertake the technique of parotid sialography with48%Lipiodol ultra-fluideunder X-ray upon78patients who were given systemic anti-infections and supporting treatments only with non-obvious-results,and classify all the cases into chronic obstructive(21cases)and nonobstructive parotitis(57cases)accoding to the results of sialography through microcatheter,then go on...

根据影像所见，将患者分为慢性阻塞性(21例)和慢性非阻塞性(57例)腮腺炎。造影前，经微导管引流腮腺内分泌液，做细菌培养及药敏试验。对慢性阻塞性腮腺炎病人，给予经导管向腮腺内灌注2%利多卡因、1%甲紫治疗。对慢性非阻塞性腮腺炎病人，用同样方法注入α-糜蛋白酶、丁胺卡那霉素、生理盐水混合液治疗。结果慢性阻塞性腮腺炎组治愈率为80.95%，慢性非阻塞性腮腺炎组治愈率为87.72%。结论造影-介入是诊断和治疗慢性化脓性腮腺炎确切有效的方法。
