Its physics signification is that geometric parameter varies with reference time proportionately. 其物理意义是几何参数相对于参考时间(RT)成比例变化。
It can handle unexpected or uncertain event, as the reference time is controlled through estimating error of the system and desired output can be adjusted based on the running state of the system. 通过对系统误差评价控制规划器的参考时间(RT),使期望的输出可以根据系统当前的运动状态进行调整,从而使系统具有处理不可预测和不确定事件的能力。
Perfect Construction means anterior, which denotes the precedence of Event Time over Reference Time(RT) in the secondary tense. 完成式是次级时制中的先时,表示事件时间前于参照时间。
For it is no solution to calculate the simultaneous equation set up by the goal of trajectory motion, through defining actual motion process as reference time, linking planning and practice, a new movement planning method based on self-defining time was presented. 针对以轨迹运动目标建立的运动微分方程不能完全求解的问题通过定义实际运动过程为参考时间(RT),建立规划与实际的联系,提出了基于自定义时间的运动规划方法。
In addition to the consideration of the average reference time duration, the recently passed time, the size of the WEB file and the cost per unit of file, the dynamic characteristic of WEB access rate is also taken into account. 新的替换算法除了考虑Web文档的平均引用时间、最近流逝时间、文档大小和单位大小价值以外,还考虑了Web业务的访问率动态改变的特征。
