查询词典 train it

After a detailed analysis of the forces in subway train's running, the dynamics mathematical model of subway train is constructed; the eventbased control technology is adopted to solve the controlling of subway, the velocity and acceleration function with respect to the distance are deduced by introducing the action reference variable in the control problem which the object is to minimize the running time. The running scheme can be programmed in realtime, the delay caused by uncertain events is avoided. So it offers a new way for the metro research.

分析了地铁列车运行过程中的受力情况，建立了地铁列车的力学模型；将基于事件的控制技术应用到地铁列车的控制中，通过引入运动参考变量，求出在以站间最小运行时间为最终目标的列车控制中，列车速度、加速度等关于列车运行距离的函数表达式，从而可以根据列车走行距离来实时调整和规划地铁的运行规律，避免人为因素或不确定性因素导致的列车运行晚点，为研究地铁列车的规划提供了一种新的方法。

In order to study the negativesequence influence to regional power grid caused by autotransformer traction power supply system, formulas of NSeq current and threephase voltage imbalance were derived, based on current distribution analysis of AT traction power supply system and singlephase VVconfiguration train substation. Employing the "train diagram" method, the realtime voltageimbalance curve was obtained in a simulation study, as well as the factors that influence NSeq and some measures to restrain it.

为研究自耦变压器牵引供电系统对地区电网造成的负序影响，首先讨论了AT牵引供电系统、单相VV接线牵引变电站的电流分布，推导得出了负序电流、三相电压不平衡度的计算公式；然后结合"列车运行图法"开发了相应的仿真程序；最后通过一个实际算例，得到了实时电压不平衡度曲线，指出了负序大小的影响因素及相应措施。

After the collision, Shanghai Municipality organized an investigation group for this accident and came to a conclusion in a shortest possible time: it is an omission in the design that caused a wrong instruction, so the down-train directly collided with a normal turn-back train on the side due to insufficient braking distance, and the accident thus happened.

事故发生后，上海市政府迅速组成事故调查组，并在最短时间内对事故作出了结论。事故的直接原因是：由于设计疏漏，造成信号系统发出错误指令，致使列车制动距离不足，使下行列车与正在折返的列车发生侧面冲撞，导致了该事故的发生。

In Great Railway Journeys, and the television series which it accompanies, six exceptional travellers share with us their discoveries, and their pleasures in travelling by train, whether in a steam train, a shabby diesel or on a steam engine footplate.

在伟大火车之旅这当系列记录片中，在六位杰出的旅行者的陪同下，分享他们的发现和火车旅行的喜悦，无论是在蒸汽火车还是小柴油火车或是在蒸汽火车的踏板上。

When tomorrow turns in today, yesterday, and someday that no more important in your memory, we suddenly realize that we are pushed forward by time. This is not a train in still in which you may feel forward when another train goe**y. It is the truth that we've all grown up. And we become different.

当明天变成了今天成为了昨天，最后成为记忆里不再重要的某一天，我们突然发现自己在不知不觉中已被时间推着向前走，这不是静止火车里，与相邻列车交错时，仿佛自己在前进的错觉，而是我们真实的在成长，在这件事里成了另一个自己。

When tomorrow turns in today, yesterday, and someday that no more important in your memory, we suddenly realize that we' re pushed forward by time.This is not a train in still in which you may feel forward when another train goe**y. It is the truth that we've all grown up.And we become different.

当明天变成了今天成为了昨天，最后成为记忆里不再重要的某一天，我们突然发现自己在不知不觉中已被时间推着向前走，这不是静止火车里，与相邻列车交错时，仿佛自己在前进的错觉，而是我们真实的在成长，在这件事里成了另一个自己。

To the hospital to see the train that I seen before. We were lucky that day, not long after we got to the station, a train coming, it was like a great dragon on the ground, spitting white smoke, running into the station while a long ringing.

那天很幸运，我们到火车站不久，一列火车就来了，它像一条快速在地上爬的巨龙，口中图着白气，长鸣一声就进站了。

The reason is many sided: 1 student and parent think " miscalculate " irrespective, as long as next time attentive dot went. The student allows to use a calculator in 2 education, the student had to the calculator depend on, often abandon when encountering seemingly complex calculation think, use a calculator directly, for instance 618, do not know to change brief into 13, achieve a result with the calculator directly however 0.33. Phase of 3 high school trains a student " put forward, analysis and the ability that solve a problem " the demand is higher and higher, of the train of thought that inscribes to solution in classroom education, thoughtway many somes more tuitional, and to operation ability, because the student has certain base, loosened with respect to some then. 4 emphasizes the training of all sorts of thinking ability overly, the training of operation ability has the suspicion that should try education it seems that, this also is one of reasons. The operation in 5 maths, no matter be numeric computation, return be algebraic type to be out of shape figure, photograph of the train of thought that inscribes with new knowledge, new solution, skill is compared and character, appear more as dry as a chip, the student does not have interest.

原因是多方面的：1学生和家长都认为"算错了"没关系，只要下次细心点就行了。2教学中答应学生使用计算器，学生对计算器有了依靠，在碰到貌似复杂的计算时往往舍弃思索，直接用计算器，比如618，不知化简成13，而是直接用计算器获得结果0.33.3高中阶段培养学生"提出、分析和解决新问题的能力"的要求越来越高，课堂教学中对解题的思路、思想方法的讲授多一些，而对于运算能力，因为学生都有一定的基础，于是就有些放松了。4过分强调各种思维能力的练习，运算能力的练习似乎有应试教育的嫌疑，这也是原因之一。5数学中的运算，不管是数值计算，还是代数式的变形演算，和新的知识、新的解题的思路、技巧相比较而言，显得比较枯燥，学生没有喜好。

I chose to go by train every time I went to the city only to gain an immediate sight of the Lake upon leaving the train, so pure, so broad and so tranquil… what a sight! Even seen afar, the grand and mistful surface of the lake is enough to rid me of any tiredness of the journey, washing away the dust over my heart! Really enjoy the dear, warm feeling at the sight of the lake, easily got drunk while immersed into the damp, warm air around the lake, it seems that my whole body has been melted away in the green shade and the brilliance of the lake

因此，每次去这座城市，我都坚决要坐火车，只是因为一下车就能看到清亮开阔平静的玄武湖，远远望去，那一大片氤氲浩渺的湖面足可洗却旅途的劳顿，涤清时常蒙尘的心灵；很喜欢看到玄武湖那种亲切温暖而熟悉的感觉，就连下火车时扑面而来的温润潮湿的气息都令我沉醉不已，仿佛整个人都已溶入那湖光绿荫中。。。。。。

This train classifies "information carrier adhering to the build" as design elements, and probes into integrated design method of it and single building separately: method of definite position, method of definite form and method of combination; Then, this train probes into integrated design method of it and colonys building , that bases on the cognitive design method: method of rhythm controls,method of node outstanding, and that aims at the design method to protect: method of protect original, method of repairing and method of renewal.

本文的第四部分提出了一体化设计的思路，将建筑附着信息载体作为设计元素，探讨了它与建筑单体一体化设计的方法：定位法、定形法、混合法；以及它与建筑群体一体化设计时，基于认知的设计方法：节奏控制法、节点突出法，旨在保护的设计方法：存真法、修缮法、更新法。
