In order to do research on pipe flow and pump characteristics of polymer flooding and water flooding rod-pumped well in especially high water-cut stage, rheometric test aimed at production stream from polymer flooding and water flooding rod-pumped well in especially high water-cut stage has been made, and the characteristic of production stream in especially high water-cut stage is confirmed as Newtonian fluid. Experiments using different mediums about pipe flow and pump characteristics is made. Frictional resistance and coefficient of friction resistance of annulus fluid between sucker rod and the pipe flow is calculated under different working conditions. Frictional resistance between plunger and pump barrel under different parameters is calculated based on related theory of pump characteristic and the strained analytical model of oil-well pump. Besides, using the theory of slit flow and hydraulic -clamping pressure, the frictional resistance is calculated, and the error between the result and measured value is no more than 13%.

为研究特高含水期水驱及聚驱抽油机井管流特性与泵特性，本文针对特高含水期水驱及聚驱井采出液进行了流变性试验，确定了特高含水期油井采出液的性质属牛顿流体；利用不同介质，进行管流特性与泵特性试验，得到了不同工况下杆、管环空流的摩擦阻力和摩阻系数；根据泵特性相关理论和抽油泵受力分析模型，计算了不同参数下柱塞与泵筒间的摩擦阻力，并利用缝隙流与液压卡紧力理论对柱塞与泵筒间的摩擦阻力进行了计算，计算结果与实测值误差在13%以内。

It is well known that the large lattice mismatch (16%) and thermal expansion coefficient mismatch between GaN and sapphire substrate are the main origins of TDs. By new growing technique of LEO, we acquired high quality GaN films almost free of TDs. The stress characteristics in GaN films with MLTB growing technique is dependent on growing systems and conditions, and the changes of stress and dislocation density are rightabout; Combining buffer layers of high temperature and low temperature is first developed to growing GaN films with low dislocation density, and the mechanism of lowering TDs density is that the first buffer layer of high temperature can make nuclear in second buffer layer of low temperature bigger. This technique also can restrain yellow luminescence effectively.

众所周知，晶格失配和热应力失配是GaN异质外延中位错产生的主要原因；为此，我们对几种降低缺陷的MOCVD外延生长方法进行了新的尝试，其中尝试了侧向外延生长技术，得到了低位错密度（小于10〓/cm〓）、高质量的GaN外延层；尝试多低温缓冲层法，发现材料中的应力特性与生长系统和生长条件有关，材料中的应力与位错密度按相反方向变化；首次尝试高低温联合缓冲层法，材料中高温缓冲层可以使随后的低温缓冲层中成核颗粒增大，从而导致随后高温GaN外延膜中位错密度降低，并且能够有效地抑制黄光峰。
