He entered his novitiate to the true wilderness with Sam beside him as he had begun his apprenticeship in miniature to manhood after the rabbits and such with Sam beside him, the two of them wrapped in the damp, warm, negro-rank quilt while the wilderness closed behind his entrance as it had opened momentarily to accept him, opening before his advancement as it closed behind his progress, no fixed path the wagon followed but a channel nonexistent ten years ahead of it and ceasing to exist ten yards after it had passed, the wagon progressing not by its own volition but by attrition of their intact yet fluid circumambience, drowsing, earless, almost lightless.44

孩子就这样进入了熟悉真正的荒野生活的见习阶段，有山姆在他身边，正如他小时候追捕兔子这类小动物度过雏形的见习时期，山姆也陪伴在他身边，这时两人裹在湿漉漉、暖烘烘、散发出黑人臭味的被子里，方才暂时对他开放来接纳他的荒野在他身后合拢了，森林在他前进之前开放，在他前进之后关闭，大车也没有固定的路可走，只有一条仅仅看得清前面十码路的通道，大车走过十码后，这段路也就湮没，这大车并没有按自己的意志往前行进，而是由人和大车所造成的纯净的气流浮托着在往前滚动，大车在打瞌睡，听不见一点声音，也几乎见不到一点光线。45

Simulation results show that the performance of the open-loop control system is poor when the model parameters change. The second system is designed via feedback linearization method. Since the path signal is introduced as feedback signal, the designed closed-loop control system improves the system robustness to the parameter perturbation. Simulation results verify that the closed-loop control system shows better performance than the time optimal control system.

前者侧重于时间最短的控制性能，但由于是开环控制，当出现参数摄动时，系统的性能会受到较大影响；后者由于引入了飞艇轨迹的反馈信号，因而相对提高了系统对参数摄动的鲁棒性，计算量较小，并且仿真结果证实了这种闭环系统设计方案可以抑制参数摄动带来的影响，与时间最优开环控制系统相比，显著提高了控制精度、改善了控制效果。

According to the characteristics of multi-class high-dimension gene expression profile, a new multi-class classification algorithm based on closed pattern was designed. Firstly an approach called path enumeration was proposed to mine closed patterns based on the vertical formatted data-table, which can reduce most redundant patterns.

摘 要：针对多类高维基因表达谱的特点，提出一种基于闭合模式的多类分类算法CBCP，即根据垂直格式的数据集采用路径枚举的方法挖掘闭合模式，极大地减少了冗余模式的产生。

So in order to improve ROP, the VTK vertical drilling technology of Baker Hughes was introduced. VTK is a kind of closed loop, automatic, and vertical drilling technology, made up of closed loop rotary steering drilling system AUTOTRAK, high-performance X-TREME motor and reliable MWD. It is able to return the well path back to vertical by adopting downhole microprocessors to analyze the measured deviation data and determine the proper force necessary for decreasing the deviation angle to guide the steering rib at the high-side to reliably stick out against the upper wellbore.
