查询词典 two-times

The Iterative Learning Control must be used on a repeatable or a peridocital system. By using motion time and iteration times as the two orthogonal vectors, a two-dimensional control system is construct, which can discribe the attribute of the dinamic behavior and learning process completely.

反覆式学习控制必须应用於具有反覆性或周期性的系统，文中将以运动时间与学习次数作为二正交向量来架构二维控制系统，使其能够完整的描述控制系统本身的动态行为与学习过程的特性。

Predeterminer):all,both,half;double,twice, three times,etc;one-third,two-thirds,etc;what,such, etc 中位限定词:the,a,zero;this, that,these,those;my,your,etc:John's,the old man's,etc; some,any,no,every,each,either,neither,enough,what, which,whose,etc 后位限定词:one,two,etc;first,second,etc;next,last,other,etc; many,much, few,little,fewer,fewest,less,least,more,most;several,plenty o f,a lot of,lots of, a great number of,a greatdeal of,a largeamount of;such,etc

在三类限定词中，中位限定词是最关键的。所谓前位限定词是指那些可以位于中位限定词之前的限定词，所谓后位限定词是指那些可以位于中位限定词之后的限定词。例如： all the four teachers 所有这四位教师前中后上述限定词的位置是固定的，不能掉换，就是说它们必须按"前位—中位—后位"的顺序排列。以此类推，如果出现两个限定词，则只能按前位—中位，前位—后位或中位—后位的顺序排列。

Two representative compounds have been determined by X-ray crystallography. The best ratio of reactants, the adequate reaction temperature and solvent have been found by contrast experiments.4. The better photoreaction conditions and irridation times have been confirmed through the different photoreaction results. It is the first time that fifty quinazoline derivatives with biological activity and four photooxidation products with urea functional groups have been obtained by photochemistry method. Two representative compounds, quinazoline derivatives and photooxidation products, have been determined by X-ray crystallography, respectively.

通过实验对比我们找到了较佳的反应物的投料比、反应温度和反应所用的溶剂。4、根据不同条件下的光反应结果，确定了硫脲衍生物的相对较好的光反应条件和光照时间，首次利用光化学手段成功得到50个具有生物活性的喹唑啉衍生物和4个具有脲基官能团的光氧化的产物，测定了两个具有代表性的喹唑啉和光氧化的产物的晶体结构。

In less than two decades, the two countries together will have more than three times as many rabid consumers as the US has

在不到20年的时间里，这两个国家拥有的疯狂消费者总数，将是美国人口的三倍以上。

If we rechange these two numbers:one other to four times as many as its original value,the average of the five numbers will become 13.Which two numbers have been changed\?I only know that the total sum of the original numbers is 45(5×9),thd total sum of the 5numbers after the first change is 40(5×8),and the total sum of the 5numbers after the second change is 65(13×5).What can Ido next\?Please help me with the problem.Thank you!Mathematics Maniac,Zhongwanting

这就要求琬婷一方面要用王牌外语准确地把她想要问的问题清晰地表达出来，只有这样网上"数字博士"才能明白你要问的问题；另一方面琬婷还必须能够正确理解网上"数学博士"对她所提问题的英语答复，这两者是相互依赖的，否则就不能正确地帮助你理解和解决问题，这就要求琬婷必须用王牌外语进行正确地表达和理解。

Before two when the season is silly, wrote two operation experience soft article about workshop net, do not know to displease which friend, also or be to hamper some my dear brother sends big money quietly, had appeared 3 times to atttack my website to today from 26 days of evening continuously.

前两天无聊的时候，写了两篇关于厂房网的运营经验软文，不知道是不是得罪哪位朋友啦，亦或是妨碍某位仁兄闷头发大财了，连续从26日晚到今天已经出现三次攻击我的网站。

Ancient times the Babylon civilization located the environment belonged to the subtropics desert climate, but benefitted from two rivers, young sent pulls the bottom river and the Tigris River mother's gracious gift, was having the exceptionally broad impact plain, but by was in the arid few rain in the middle of the desert climate, on the one hand thus created the local wooded area to be very few, on the other hand was the great plains which so stretched to the horizon smoothly like baffles, from this has become the sierra absolute forbidden area, from this occupied the plain center region people, even if wanted to use the firm stone material, also could because was far away, either was gives way before difficulties looks Shi Xing to sigh, either was after pays the extremely soaring price, shipped in by farSeveral stones only can use in actually carving the magnificent precious tombstone, even was in some plain person all not once has seen the mountain appearance for a lifetime, in brief took root in two river basin Cuban Billen civilization, finally is framed was the soil texture civilization, they created the cuneiform character, all could not but engrave above the thin clay tablet, was recording the exceptionally precious history, obviously in the different region humanity, all was influences subtly sparely no effort regarding the side each kind of environment resources use.

古代巴比伦文明所处的环境属于亚热带沙漠气候，但得益于两条河流，幼发拉底河与底格里斯河母亲般的恩赐，拥有着异常广阔的冲击平原，但由处于干旱少雨的沙漠气候当中，从而造成一方面当地森林面积很少，另一方面就是如此一望无垠平坦如砥的大平原，由此成了山脉的绝对禁区，由此处在平原中心区域的人们，即使想使用坚固的石头材料，也会因为路途遥远，要么是知难而退望石兴叹了，要么是在付出极为高昂的代价后，远远运来几块石头却只能用于雕刻华丽珍贵的墓碑，甚至是有些平原中的人一辈子都不曾见过大山的模样，总之植根于两河流域的古巴比伦文明，最终被定格为土质文明，就连他们所创造的楔形文字，都不得不刻印在薄泥板之上，来记载着异常珍贵的历史，可见不同区域内的人类，对于身边各种环境资源的利用都是潜移默化不遗余力的。

Secondly, the author has set up the Factor Set, Factor Weight Set, Evaluation Set and Evaluation Matrix based on the Fuzzy Mathematics, therefore the quantification of expert's experiences is solved. Following the example of product design procedure consisting of designing, collating and checking, the Two-stage Fuzzy Synthetic Evaluation has been established in order to supply the evaluating method of design quality for drawing die-face. After two times of eligible analysis above, the synthetic optimizing design of geometry, material and process can be done with simulation.

以模糊数学为基础，通过确定影响覆盖件拉延模型面设计的因素集、因素权重集、备择集和评判矩阵，解决了专家设计经验知识的量化问题，并建立二级模糊综合评判方法，据此设计、校对、审核等技术人员可以共同对拉延模型面设计质量进行优劣评判和修改；在前面二次分析合格的基础上，利用有限元仿真技术进行几何、材料、工艺多因素综合的优化设计。
