本文采用压力模型计算出稳定弧光制粉时的气相空间温度在373K以下；从电流密度和电导率角度计算出等离子体电弧场中心温度高达5000-6500K；由此得出弱电离等离子体自由弧的自身温度场即使没有外界强制冷却，在等离子体焰区特征半径(约1.26cm)范围内的温度梯度就可达4787℃/cm，这是电弧等离子体温度场分布高度集中的具体表现，也是纳米金属粉末无须液氮冷却就能生成的本质原因，阐释了等离子体温度场自身的极大温度梯度是金属粉体纳米化的控制机制。

Firstly, a class of affine nonlinear systems are considered. The single-layered neural networks are used to approximate the nonlinear functions of the systems. Stable adaptive control algorithms are presented based on system states feedback and system output feedback respectively. The boundary of the tracking error is guaranteed. Then, by using the technique of input-output linearization, the stable adaptive control method for general nonlinear systems is proposed. Finally, the effectiveness of the proposed adaptive control algorithms are verified through the simulation researches for the control of robot manipulator.

In this report, half-esterification between these pendent hydroxyl groups of hydroxyl-PU and maleic anhydride could lead to new pendent groups, carboxylic groups. These highly polar carboxylic groups in the side chain of PU could play the role of internal emulsifier. They had self-dissociation ability in the water or were neutralized first by appropriate amount of base. Then, PU bearing carboxylic group could dispersed steadily in the water, named aqueous-based polyurethane dispersion.
