Previously, researchers raised the accuracy that a robot′s hand tracks a specified path in Cartesian space mainly through increasing the number of knots on the path and the number of the path′s segments.

在以往的研究中，往往是通过在设定的路径上增加节点数和路径分段数来提高机器人手部跟踪设定路径的精度，但这种方法会导致在线计算量大幅度增加。

If the two terminals of a path coincide, the path is a closed path and is called a circuit.

如果一条路线的两个端点相交，那么它是一个封闭的路线，称之为回路或环形。

A closed path is fundamentally different from an open path: it's one continuous path and has no start or end.

闭合路径和开发路径的根本区别是：闭合路径是没有开始或结束的连续路径。

Relation between geometrical contour error of inner corner and machining condition is investigated by the experimental plan of Taguchi quality design. Through the quantitative analysis, the geometrical contour error is mainly affected by wire tension and flushing pressure. By regression analysis, a mathematical model is established to estimate cutting path error of corner cutting. According to the estimated cutting path error, the program path is corrected.

研究首先以田口式品质设计实验计画法来探讨加工参数与隅角形状误差间的关系，从变异数分析的结果得知，线张力与冲水压力是对於隅角精度影响最显著因子，应用回归分析建立转角加工路径误差量估测模式，利用此模式以预测不同加工条件下隅角加工路径误差量，依据预测加工路径误差量计算轨迹补偿量，实验结果证明本文所提出轨迹补偿策略可有效提高60%之隅角加工精度。

Robot path planning is to give a collision free path or shortest path of a moving robot.

由于空间中的机器人以及各种物体可以通过空间中的多面体加以模拟。

By employing blur synthesizing score to assess the effect the influencing factors give to the traffic states, a congregate of scenes was established to describe the incredibility of traveling time in the transporting web and then the optimal solution of this model was calculated by taking advantage of a model of absolute and relative reliable path finding designed by Minimax theory, choosing a reliable path from jumping-off point to destination and making use of a arithmetic based upon dynamic programming. By so doing, the reliable path to the target could be grabbled when emergency erupted, this would lessen the complexity of how to resolve the proposition of transportation scheduling of relief commodity.

通过对以上问题的研究，可以帮助应急物资保障人员构建出一个可以在突发事件爆发后快速、高效地保障救援物资供应的应急物流系统，为物资运输搜索可靠路径，设计最小化时间与成本物资运输与车辆调度方案，为突(来源：AB71b0C论文网www.abclunwen.com)然爆发的灾难提供有效、实用的应对方案与决策模型。

We have heard of "Katyusha" and talk to, heard of "path" of the chant:"a thin and long winding path, has been leading to fog in the distance, I would like to follow this tortuous path, Follow my love on the battlefield."

我们听过《喀秋莎》的倾诉，听过《小路》的咏叹："一条小路弯弯曲曲细又长，一直通往迷雾的远方，我要沿着这条崎岖的小路，跟着我的爱人上战场。"

On the basis of Venigalla\'s work,we adopted two path-based algorithms, namely,gradient projection algorithm and disaggregated simplicial decomposition algorithm to solve nonadditive path cost traffic assignment problem under different engine operating modes.We compared the above two algorithms in a network example which showed that compared with the traditional Frank-Wolfe algorithm, the two path-based algorithms had a more quicker convergency while getting optimal solution,and it can obtain a satisfying solution in most cases.

2在Venigalla等人研究工作的基础上，分别采用基于路径的梯度投影算法(gradient projection，GP)和基于路径的非集计的单纯分解算法(disaggregated simplicial decomposition，DSD)来求解考虑不同发动机启动模式下，具有非可加路径费用的交通分配问题，在实例计算中比较了这两种算法的计算性能。
