Nonlinear space-charge effects of low energy intense charged particle beams arestudied by analytical method. The relation between changes of emittance diagramsand initial current density distributions for zero temperature beams is deter-mined. Approximate methods for calculating changes of emittance diagrams for beamsof small temperature under the action of nonlinear space-charge field and increment ofeffective emittance of beams are obtained.

The technique of intraparticle temperature measurement is used to measure the transient temperature profile of a cupric oxide catalyst pellet during its reduction at various hydrogen concentrations and surrounding temperatures. This process is simulated by a homogeneous gas-solid reaction model,and the resulting partial diff- erential equations are solved by the explicit Runge-Kutta method after discretiza- tion of them by the orthogonal collocation method. The results obtained by measu- rement and simulation have a good agreement. Both the experimental and simulation results show that as soon as the reduction process begins, the temperature inside the pellet increases quickly and passes through a maximum. Later the pellet temperature approaches a stable temperature which is higher than the surrounding temperature. The maximum temperature rise is correlated with the hydrogen concentration and the surrounding temperature, and an empirical formula is obtained in order to calculate the maximum temperature rise. According to the results obtained, this paper finds out that the temperature gradient is mainly in the interphase and the concentration gradient is mainly inside the pellet.

本文采用了粒内测温技术,实测了在不同氢浓度及环境温度下铜催化剂用氢还原 的过程中粒内温度的动态分布,并用非稳态下的均匀模型模拟此过程。对此模型用五 点正交配置法离散后用显式龙格-库塔法所得的结果与实测数据接近。 实测与模型计算均表明,在还原开始后粒内温度迅速升高并达到一最大值,在反 应后期粒子温度逐渐趋向于一个高于环境温度的稳定温度. 本文对不同氢浓度及环境温度下的最大温升进行了关联,得到了计算最大温升的 经验式.根据实测与计算结果分析了粒内与相间的温度与浓度梯度,得出了温度梯度 主要存在于相间而气相浓度梯度主要存在于粒内的结论。

It is proved by experimental investigation presented in this paper that, under the condition of low pressure plasma spraying, the mechanical properties of TiO2 coating are not dependent on the coating structure but mainly decided by the temperature and speed of TiO-2 particles prior to the formation of coating. For higher temperature and speed of TiO-2 particles, a more flatshaped powder coating is formed, more intense binding forces between the particles occur, and higher mehanical properties of coating are obtained. Therefore the spraying parameters such as plasma power, spraying distance, and the pressure of spraying atmosphere exert an great influence on the mechanical properties of the coating while the effect of the flow rate of auxiliary H2 gas is very small.

文本通过实验研究,证明了在低气压等离子喷涂条件下,TiO_2涂层的机械性能不是依赖于涂层结构,而主要由形成涂层前的TiO_2粒子的温度和速度所决定;如果形成涂层前的TiO_2粒子温度越高并且速度越大,就能形成更加扁平状粒子的涂层,增加粒子间结合力,使涂层机械性能提高。因此,喷涂规范中的等离子弧功率、喷涂距离和喷涂室压力对涂层机械性能有较大影响,而等离子弧辅助气氢气流量的影响甚小。
