By using the principle and method of elastic deformation, an investigation in the bending deflection of the variable rigidity combined casing string is conducted. By adopting the expression of trigonometric series, the bending deflection equation and calculation method are worked out. Under the condition of variable rigidity, the deflection of the casing is inversely proportional to the variable rigidity coefficent β, and to the inertia moment I only under the condition of the space between two pivot points...

By using the principle and method of elastic deformation, an investigation in the bending deflection of the variable rigidity combined casing string is conducted. By adopting the expression of trigonometric series, the bending deflection equation and calculation method are worked out. Under the condition of variable rigidity, the deflection of the casing is inversely proportional to the variable rigidity coefficent β, and to the inertia moment I only under the condition of the space between two pivot points being constant. An example of calculation shows that the error of deflection caused by variable rigidity cannot be neglected, and the relative or is 35% ~ 45% compared with that calculated by using the traditional method. By using the series equation and energy method presented in this article, the bending deflection of the variable rigidity combined casing string can be calculated rapidly, and this is of great importance to determine the location of the casing centrilizers.

利用弹性变形原理和研究方法,对不同钢级、壁厚的变刚度组合套管柱的弯曲变形计算进行了研究。采用三角级数的表达式,导出了挠曲变形方程及计算方法。在变刚度条件下,套管挠度与变刚度系数β成反比,在两支点间距为常数情况下,仅与惯性知I成反比。实例计算表明,在变刚度组合套管柱中,变刚度引起的挠度计算误差不能忽略,与传统的不变刚度计算方法相比,相对误差在35%~45%之间。应用本文的级数方程和能量方法,可迅速计算变刚度组合套管柱的挠曲变形量,这对合理确定套管扶正器安放位置、提高套管柱居中度都很重要。

The pivot bearing system of the sealless centrifugal pump consists of an impeller shaft made of Al2O3 ceramics and two pivot bearins made of ZrO2 ceramics. The impeller has an outer diameter of 72mm and an inlet diameter of 24mm. The heights of six vanes on the top of impeller are 5.5mm and 3mm respectively...

We are developing a centrifugal ventricular assist pump, as an alternative to the roller pump for cardiopulmonary bypass, or as an short-term cardiac assist pump for patients with heart failure. The pivot bearing system of the sealless centrifugal pump consists of an impeller shaft made of Al2O3 ceramics and two pivot bearins made of ZrO2 ceramics. The impeller has an outer diameter of 72mm and an inlet diameter of 24mm. The heights of six vanes on the top of impeller are 5.5mm and 3mm respectively in inlet sides and outlet sides. In the end plate of the impeller, 8 pieces of NdFeB magnet are embedded and provide the force for magnetic coupling with 8 pieces of NdFeB magnet embedded in the opposite end of the driving motor. By the force of the magnetic coupling, the impeller rotates. The maximum admitted conditions of this centrifugal pump are flow of 9L/min against 40kPa total pressure head at 2400rpm.

我们正在研制一种心室辅助径流泵,可在体外循环中代替血泵使用,也可作为心衰病人短期心脏辅助泵使用。此种无密封件的径流的泵的轴尖支承结构由一根氧化铝陶瓷制成的叶轮轴和两只氧化锆陶瓷制成的轴尖轴承组成。叶轮的外径为72毫米,进流处直径为24毫米。位于叶轮上表面的六个叶片的进流侧高度为5.5毫米。出流侧高度为3毫米。在叶轮的底平面内装有八片钕铁硼磁铁,在与其位置相对应的驱动电机的端部装有八块钕铁硼磁铁,共同组成磁耦合作用力。通过磁耦合力驱动叶轮转动。该径流泵的最大许可工况为每分2400转并达到40千帕斯卡的压力时,可产生每分9升的输出流量。

Research study is the one of significant study methods advocated currently by the world educationists. Combining the other current study theory, we may further apprehend the research study as that it is the independent study of students on the base of structuring study theory,and must be collectivity cooperating. The development of the research study in university teaching may start from two pivots of classroom teaching and curriculum project.

 研究性学习是当今世界教育界倡导的重要学习方法之一。与当今的其他学习理论相结合,可以将研究性学习进一步理解为在建构主义理论基础上的、学生自主的、集体合作的研究式学习。在大学教学中开展研究性学习,可以重点从课堂教学和课程设置两个方面开始。
