placidity

• Based on the analysis of the fuzzy control principle , this paper presents an fuzzy control method with adaptable coefficients which is used in position control loop . therefore , the speed and placidity demands can be satisfied furthest at the same time
  本文在分析模糊控制基本原理的基础上，给出了一种比例因子模糊自调整的模糊控制策略，将其用于外环的位置控制，以最大程度地满足高速卷取对台阶回避快速性和平稳性的要求。
• Her only real comfort was when the child lay in the placidity of sleep . then she was sure of her , and tasted hours of quiet , sad , delicious happiness ; until - perhaps with that perverse expression glimmering from beneath her opening lids - little pearl awoke
  只有在孩子躺下安然入睡时，她才感到真正的宽心这时她才能确定她的存在，体陈上几小时的沁人肺腑的恬静和幸福，直到小珠儿一觉醒来也许就在孩子刚刚睁眼的时候，那种倔劲又表现出来了！
• The rover performance and task life decide whether the exploration mission would succeed . the functional acquirements of lunar rover are analysied . locomotion performance evaluation including terrainability , driving placidity over - obstacle ability , untipover stability , steering sensitivity etc . , is built up and used to lunar rover
  本文通过分析月球车的功能需求,首先初步建立了包括地面自适应性、行驶平顺性、越障爬坡性能、抗颠覆能力、转向灵敏度等在内的月球车的移动性能评价模型,用于月球车的性能分析和评价。
• The results indicate that two - brace - slider rover has the same over - obstacle ability with rocker - bogie rover , better driving placidity , ground adaptability , steering delicacy and worse untipover stability than rocker - bogie rover . finally , the prototype of two - brace - slider rover is developed to validate locomotion performance evaluation built in this paper
  结果表明双曲柄滑块月球车的越障性和六轮摇臂月球车相当,平顺性、地面适应性、转向灵敏度优于六轮摇臂月球车,抗倾覆性不如六轮摇臂月球车。
