中文摘要本论文针对双足机器人进行完整动力学模式推导和步伐轨迹追踪控制的研究。

Considering the factors such as randomness of natural lightning locus and the coexistence of primary and secondary leaders, it is necessary to lead in the concept of dynamic lightning protection shielding angle. It is suggested that the angular bisector of practical protective angle formed by ground wire or earth pin in UHVAC transmission line and conductor should be aligned with the direction of lightning leader as well as the ratio of vertical span to horizontal span and the impact of wind speed should be considered.

考虑自然闪电轨迹的随机性和雷电主先导与次先导并存现象等因素，有必要引入动态防雷保护角概念，建议特高压交流线路中地线对导线的实际保护角形成的角平分线应与雷电先导的来向一致，并应计及垂直档距和水平档距的比值和风速的影响。

This model can be used to determine the proper angle and position of lance. In Chapter Five, based on characteristics of Pulverized coal combustion in blast furnace, the mathematical model in the blowpipe and the raceway, including coal movement, devolatilization and combustion, was put forward.

为消除对高炉风口磨损，本章结合高炉喷吹煤粉特点，发展了一个能全面考虑气固两相流煤粉燃烧和煤粉颗粒轨迹的三维计算程序，并对所采用的理论进行了详细介绍。

The most striking feature of this machine is the realization of the space saddle-type welding seam welding control system by using the interpolation arithmetic, which can replace the method of mechanical differential outfit simulated space curve movement, guarantee the stability of the welding line, and make the track of the welding blowpipe more accurate and the mechanical structure simpler.
