The experiment study about the subcritical normalizing holding temperature effects the macrostructure and hardness of the 40SiMnCrNiMoA steel shows: When subcritical normalizing holding temperature is 760℃, the ferrite in the mixture phase structure is lumpish, the hardness of the steel is low (about HRC32), and when the holding temperature is over 800℃, the hardness of the steel is about HRC49, the ferrite in the mixture phase structure is in old critical range austenite grain boundaries, it is disadvantage for the steel strengthening. When the holding temperature is 780℃, the mixture phase structure is mixture phase structure including the strip ferrite、martensite and bainite, the ferrite is less than 20%wt, its grains are fine and even, the hardness of the steel is about HRC38, it is in the range of HRC35-40 which is the long-life drill rod needed.

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。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.
