Using of optical microscopy, X-ray diffraction, transmission electron microscopy, hardness and tensile testing, the effect of thermal exposure at high temperatures on the microstructures and of high-temperature tensile properties of rapidly solidified AlCrYZr have been studied. The results show that there are two main phases,Al20Cr2Y(cubic, a=1.437 nm) and DO23Al3Zr(terganal, a=0.4 013 nm , c= 1.732 nm), in the as-solidified alloy. The Al20Cr2Y phase can maintain its cubic structure at 500℃, but the particles coarsen remarkably and even become lumpish. In coarse lumpish Al20Cr2Y phase the plane faults and twin structures exist.

摘 要：采用金相、 X射线衍射、透射电镜、硬度测定和拉伸试验研究了高温热暴露对快速凝固AlCrYZr合金显微组织影响和高温下力学性能的热稳定性，结果表明，快速凝固AlCrYZr合金主要第二相为Al20Cr2Y(立方，a=1.437nm)和DO23Al3Zr(正方，a=0.401 3nm， c=1.732nm)，Al20Cr2Y在500℃热暴露尚能保持其立方结构，但质点明显粗化，甚至块状化，在粗大的Al20Cr2Y相中存在有层错和孪晶结构。

The operating range suitable for three-phase reaction was obtained and a mathematical model established. The results show that MSB formed by fine magnetizable powder and fliudizing flow can be operated stably in a wide range. MSB has three kinds of regimes: particulate, chain, and magnetically condensed. In these regimes, the chain regime is the best for three-phase reaction. When Ni-RE-P catalyst particles mixed with some iron powder, magnetically stabilization is easily achieved; therefore, it is possible that NiRE-P catalyst can be controlled in the bed for reaction more easilly if adding certain percentage of iron powder.

研究结果表明：细粉铁磁性颗粒形成的磁稳定床可在较宽流速范围内稳定操作，该磁稳定床有三种操作状态：散粒状态，链式状态和磁聚状态，其中有利于进行气液固三相反应的操作状态是链式状态；当磁稳定床在最小流化速度和带出速度之间操作时，床层处于链式状态；最小流化速度和带出速度可用（1-24）、（1-25）、（1-27）、（1-33）式计算；弱软磁性Ni-RE-P非晶催化剂中混入定量铁粉颗粒后便可形成磁稳定床，因此利用混入铁粉颗粒在外加磁场作用下控制弱磁性非晶催化剂颗粒进行反应的方法是可能的。

The thesis is based on the architecture of All-Digital Frequency and Phase Synthesizer (All-Digital PLL) which is published by Hugh Mair and Liming Xiu. The architecture makes multiple signals of the same frequency and the same phase difference the output of a voltage-control-oscillator to be the internal input of the DCO (flying-adder architecture), and we utilize the control word to decide the desired synchronized output signal.
