In this paper an experiment of human locomotion was carried out using a motion capture system to extract the human gait features. The modifiable key gait parameters affecting the dominant performance of biped robot walking were obtained from the extracted human gait features. Based on the modifiable key gait parameters and the Allowable Zero Moment Point （ZMP） Variation Region （AZR）, we proposed an effective Bio-inspired Gait Planning （BGP） and control scheme for biped robot to- wards a given travel distance D. First, we construct an on-line Bio-inspired Gait Synthesis algorithm （BGSN） to generate a complete walking gait motion using the modifiable key gait parameters. Second, a Bio-inspired Gait Parameters Optimization algorithm （BGPO） is established to minimize the energy consumption of all actuators and guarantee biped robot walking with certain walking stability margin. Third, the necessary controllers for biped robot were introduced in briefly. Simulation and experiment results demonstrated the effectiveness of the proposed method, and the gait control system was implemented on DRC-XT humanoid robot.

为了解天然气开采过程中钻井废弃物用固化池处置前后污染物随时间的消减变化及固化池渗滤液对地下水的影响,本研究分别采集川东气田固化池的渗滤液和气田作业区域地下水样品,分析渗滤液和地下水中污染物浓度水平.结果显示,与2013年原完井废弃物浸出液污染物浓度相比,川东地区2022年各场站大部分固化池渗滤液中污染物仍以常规污染物COD为主(92.6%),而氯化物、石油类和硫化物等特征污染物浓度经固化池处理后均未达到GB/T 16848-2017《地下水质量标准》Ⅲ类标准所规定的标准限值.沿江地区和非沿江地区固化池渗滤液中氯化物浓度具有显著性差异(p0.05).2022年部分地下水监测井检测结果显示川东气田固化池渗滤液并未对周边地下水质产生明显影响,但渗滤液指数计算结果显示,240个场站中有3处场站固化池渗滤液呈较高环境风险,可能对当地地下水资源造成潜在污染风险.

通过摩擦磨损实验,对两种400HBW级低合金马氏体耐磨钢27MnTiB和35CrMo进行耐磨性研究。结果表明:与35CrMo钢相比,27MnTiB钢的平均摩擦系数较小。此外,白光干涉仪测量显示27MnTiB钢的磨损轨迹较窄且较浅,27MnTiB钢的磨损体积和磨损率均小于35CrMo钢,展现出更好的耐磨性。扫描电镜观察发现两种样品磨痕形貌中均有犁沟和碎屑,35CrMo钢的磨痕中存在分层,说明发生疲劳磨损。同时讨论磨损机理,并分析影响耐磨性的因素。
