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。

Given the pressures of these harsh realities, mankind has no choice but to re-examine its social and economic behaviour and its path of development. Traditional ideas of considering economic growth solely in quantitative terms and the traditional development mode of "polluting first and treating later"are no longer appropriate when considering present and future requirements for development. It is now necessary to find a path for development, wherein considerations of population, economy, society, natural resources, and the environment are coordinated as a whole, so that a path for nonthreatening sustainable development can be found which will meet current needs without compromising the ability of future generations to meet their needs.

在这种严峻形势下，人类不得不重新审视自己的社会经济行为和走过的历程，认识到通过高消耗追求经济数量增长和"先污染，后治理"的传统发展模式已不再适应当今和未来发展的要求，必须努力寻求一条人口、经济、社会、环境和资源相互协调的、既能满足当代人的需求而又不对满足后代人需求的能力构成危害的可持续发展的道路。

The interpolate algorithms of three-order NURBS curve and double three-orders NURBS surface are presented. The expressions of partial derivative and normal curvature of NURBS surface are derived by the theory of differential geometry. The geometric characteristics of different curvature area of the free-form surfaces are analyzed in detail. All these work lays a theoretical foundation for constructing the cutter location calculating model of free-form surfaces NC machining. 2 On the basis of analyzing the methods of cutter path generation, the standard of evaluating the various methods of cutter path generation is presented. The method of generating cutter path with constant scallop height is presented for the first time.
