The small company made the long descent in silence, stopping thrice to refresh themselves along the way.
小队伍安静地下行，过程中三次停顿休息。
Given that the world has gravity, that upward velocity won't last long; eventually, the sphere reaches the apex and begins its descent.
由于这个环境中具有地心引力，因此向上的速度不会坚持很久；最后这个球会上升到顶点并开始下降。
Thus they reached the verge of an incline down which the road stretched in a long straight descent of nearly a mile.
他们就这样走到了一个山坡的顶上，再往前就是从山坡上通向下面的一条笔直大道，差不多有一英里长。
So at every nonstationary point there exists at least one feasible descent direction, every iterate generated by the methods is feasible so long as the initial iterate is feasible.
这样在每一个非稳定点处至少存在一个可行的下降方向，在初始点是可行点的条件下，此算法产生的每一个迭代点都是可行点。
