查询词典 can it be that

Because the workpiece is in dynamic balance, the resultant moment acting on it should be zero. Introducing the moment from lapping tool and press head a moving differential equation is built. In this equation only workpiece rotating speed is unknown. It means that workpiece rotating speed can be got by this equation. Since there is a transcendental function in integral function of the equation an analytic result can not be got, only digital result can be got by a computer. Thus a change rule of workpiece rotating speed with lapping parameters is known, e.g. the radius of press disc ball socket, radius of press head ball, the distance between the workpiece rotating axis and lapping tool rotating axis, workpiece radius, modulus of elasticity of the press head and press disc, friction coefficients between the lapping tool and workpiece, and between the head and disc, pressure between the lapping tool and workpiece and pressure between the press head and press disc.

因工件处于动态平衡状态，其上所受到的来自于磨具和压头的力矩应相等，将二力矩表达式联立，建立工件运动微分方程，该方程中只有工件的旋转角速度是未知量，因此可以求出工件旋转角速度，但该方程积分式中含有超越函数，得不出解析解，只能通过计算机求出数值解，得出工件旋转角速度随各研磨参数的变化规律，如压盖球座半径、压头的球头半径、工件回转中心相对磨具回转中心的偏心距、工件半径、压头和压盖材料的弹性模量、磨具与工件间的摩擦系数、压头压盖间的摩擦系数、磨具与工件间的压强、压头压盖间的压力等。

From the aspect of word class, that can be as pronoun, adjective, adverb, and conjunction. From the aspect of syntactic function, that can be as subject, object, predicative, and adverbial, it can also introduce nominal clauses, attributive clauses and adverbial clauses. Some idioms are constituted by that and other words.

从词类上讲，that可以是代词、形容词、副词、连词等；从句法上讲，that 可充当主语、宾语、表语、状语等，that还能引导名词性从句、定语从句，与其它词搭配还能引导状语从句，一些习用语可以由that和其它词构成。

Partly it has great practical value – you can wrap it around you for warmth as you bound across the cold moons of Jaglan Beta; you can lie on it on the brilliant marble-sanded beaches of Santraginus V, inhaling the heady sea vapours; you can sleep under it beneath the stars which shine so redly on the desert world of Kakrafoon; use it to sail a mini raft down the slow heavy river Moth; wet it for use in hand-to-hand-combat; wrap it round your head to ward off noxious fumes or to avoid the gaze of the Ravenous Bugblatter Beast of Traal (a mindboggingly stupid animal, it assumes that if you can't see it, it can't see you – daft as a bush, but very ravenous); you can wave your towel in emergencies as a distress signal, and of course dry yourself off with it if it still seems to be clean enough.

一方面是由于它有着非常实际的使用价值——当你跳跃着穿越Jaglan Beta的冰冷的月亮中间时，可以把毛巾裹在身上用来取暖；在Santraginus V的灿烂的大理石沙子的海滩，你也可以躺在毛巾上，呼吸浓烈醉人的海洋蒸汽；也可以在Kakrafoon的沙漠世界里，在红色的恒星照耀下，盖着毛巾睡觉；用它做帆，在缓慢宽阔的Moth河上泛舟；在近身搏斗中打湿了做武器；包住脑袋来防止毒气侵袭或者避开Traal的贪婪虫鸣兽的喋喋不休（一种发自内心的愚蠢的动物，它总是认为如果你看不到它，它也就看不到你——蠢得像灌木，却很贪婪）；可以在紧急情况下挥动毛巾表示求救信号；当然，也可以用来擦干身体——如果它看起来还是足够干净的话。

This paper has studied the physiological and biochemical changes during the period of forming strong buds of tree peony, and expect to provide academic basis for extending its view value and economic benefit . The main results are as the following:1 Under the field condition, Characteristics of photosynthesis of tree peony are very regular. From before blooming to the prophase of abducting buds that after blooming ,that is April,May and June,the net photosynthetic rate of tree peony is higher than the other period .It indicates that this period is very important for accumulating photosynthetic products of tree peony . So, if we want to get quality flower of tree peony ,it is very important to strengthen the management of tree peony cultivation and to ensure provide the fertilizer and water.2 From the middle ten days of June, with the time elapsing and with the environment conditions worsening, the characteristics of photosynthesis of tree peony decline deeply. But it is different among different tree peony breeds. For example , cv. Wu Long Peng Sheng can also has higher net photosynthetic rate, it indicates that cv. Wu Long Peng Sheng is super than the other two tree peony breeds when adapting the environment conditions and cv. Wu Long Peng Sheng has wide prospect to extend .3 The main factors of effecting the characteristics of photosynthesis are stomatal factor and non-stomatal factor ,that is the ability of photosynthesis of leaf cells. Under the environment of high light intensity in midsummer, if overshadow tree peony properly, then it can slow the declining of chlorophyll content, and increase the net photosynthetic rate and benefit for the accumulating of photosynthetic products.4 The content of soluble sugar in the root of tree peony is the highest among different organs during the period of forming strong buds . According to analyse ,we believe that the soluble sugar will compose starch then, and provide the solid base of material for the growth and development next year. It provide us strong academic basis of adopting the method of cultivating root and protecting root under thefield environment conditions .In other words ,it will help to increase the health level of the whole plant of tree peony and will be beneficial to forming quality tree peony flower if we strengthen the management of root. 5 To tree peony, the endogenesis hormone is important for its growth and development .In the prophase ,that is about the blooming of tree peony and the mid-summer ,IAA and ZR contents are higher and GA content is lower and its changes are very little, and the content of ABA is decreasing . This indicates that IAA and ZR act the important promote function for growth and development of tree peony in this period, and the function of GA is not important. Bur in the period of anniversary senescence of tree peony , the content of IAA and ZR begin to decrease ,while the ABA content has a certain rebound .T

本研究对几个牡丹品种壮芽形成过程中的某些生理生化变化做了研究，以期了解牡丹生长发育过程中生理生化的变化规律，探讨大田栽培条件下提高牡丹花质量的栽培措施和管理技术，为提高牡丹的观赏价值和经济效益提供理论依据，结果如下：1 大田栽培条件下，牡丹光合特性在生长发育过程中表现出极强的规律性，牡丹各品种的光合速率从牡丹开花前，到牡丹花谢后的花芽诱导期前期（6月10日之前），也就是在4、5、6月份，各牡丹品种的净光合速率相对与其他时间都维持在比较高的水平，这说明，在这段时间，是牡丹光合产物积累的重要时期，因此，要保证得到高质量的牡丹花，在这段时间加强对牡丹的栽培管理，保证这个时期的肥水供应十分重要。2 从6月中旬后，随时间的推移，环境条件的恶化，牡丹的光合性能剧烈下降，但是不同牡丹品种间仍有差异，比如，乌龙捧盛仍可维持较高的光合水平，这说明了乌龙捧盛这个牡丹品种对于环境的适应性较之其他牡丹品种高，有着广泛的推广前景。3 影响牡丹光合性能的主要因子是气孔因素和非气孔因素即叶肉细胞的光合能力，在盛夏高温高光强的环境条件下，对牡丹进行适当遮荫，能缓解牡丹叶绿素水平的下降，适当提高Pn，有利于光合产物的积累。4 可溶性糖在牡丹各品种的壮芽形成过程中，根中可溶性糖的含量在牡丹各部位中始终维持最高水平，分析认为这些可溶性糖在根系中进一步合成淀粉等储藏性物质，为来年牡丹的生长提供雄厚的物质基础，这为我们在大田栽培条件下对牡丹采取养根护根的栽培措施提供了有力的理论依据，即在大田栽培条件下，加强对牡丹根系的管理，有助于提高牡丹整株的健壮程度，有益于形成高质量的牡丹花。5内源激素对牡丹的生长发育调节作用是十分明显的，在前期，即开花前后和盛夏，IAA和ZR含量维持在比较高的水平，GA含量低且变化不明显，ABA含量逐渐降低，说明了IAA和ZR对牡丹在这段时间内的生长发育起到重要的促进作用，GA的作用不是很明显，ABA可能在高温高光强下有明显的升高，也说明了ABA的确有一些促进作用，但是到了牡丹周年衰老期，IAA和ZR的含量开始下降，ABA含量却有了一定程度的反弹，说明了IAA和ZR的作用开始降低，ABA起到了促进衰老的作用

Flipping through the channels Can't seem to understand Why so many children Losing their mums and dads I remember a time there would be rainbows Now we're living in a time with darker skies There was heavy rainfall down in Mississippi People lose their families to that endless storm I remember days there would be freedom Let it be today show the way It doesn't matter what colour Or where abouts you are This world that we have is for everyone So don't you give up We'll pass the test of time Coz I can't make it through Without you Snowy is the weather down in Chicago I guess the world is changing Even faster than me and you I remember spring there would be flowers Bring me back again Oh Lord won't you please?

似乎无法理解为什么这么多孩子失去妈妈和爸爸我记得有一次会有彩虹现在，我们生活在一个与黑暗的天空时间有大雨下来密西西比河人们失去家人的无尽风暴我记得天会有自由让它成为今天带路不要紧什么颜色或者你了解我们这个世界上，我们对每个人都所以，你不放弃我们将通过时间的考验怎么把我过不去没有你雪是在芝加哥的天气下我想世界上正在发生变化即使速度比我和你我记得春天将会有花带我回来了老天啊，不好吗？

I read all that some can not believe her, though my family conditions may also be, but still can not come to that point where she just started to accept I can be over time, and I felt very uncomfortable, and Wolia one out, then the disparity would betray oneself, of course, that is definitely poor me, I do not know his own vanity at work, or it's jealousy, in this moment I had, had now to live with very good I also started feeling can not be complacent, and this issue in the end is out on me or her people?

我看了都有些不敢相信她，虽然我的家庭条件也可以，但仍不能到这一点，她才开始接受我可以随着时间的推移，我感觉很不舒服，Wolia一出，然后贫富悬殊会背叛自己，当然，这肯定是我差，我不知道他的工作，自己的虚荣心，或者是嫉妒，在这个时刻我，现在已经住在一起非常好，我也开始感到不能自满，这最后的问题是出在我和她的人民？

This week teacher has asked as about the learning puzzle, our puzzle is that we do not have enough courage to express our idea to others, so that if the teacher start to ask question to us, we might refuged from out group, we are also to be afraid of English, although it may not so difficult, but once if we feel scared and we can not express our idea clearly. So that the teacher suggested that we should started form the easy part, just like the children sketchbook or some English songs, first we should solve all the puzzles we have come up against and not to avoid it, so that we can love it truely, and not only just for the examination or study English, therefore we can understand it indeed.

本周老師問了我們的學習困難，我們的問題在於沒有勇氣做表達，也因此只要老師一開始問問題，我們就會有逃避的動作，也因此對英文有逃避的感覺，或許原本沒有這麼困難，但是只要一逃避就無法正確的表達出心裡想說的話，因此老師建議說我們可以從比較簡單的項目開始練習，像是兒童繪本，或是英文歌，先讓自己不要去逃避，同時可以是真正的喜歡它，而不單單只是為了考試或是學習而學習，如此一來才能夠真正的學會它。

Moreover, the control circuit (103) is designed in such a way that it can be used to control at least one of the varactors (105, 109) so that a resonant frequency of the corresponding resonator can essentially be set to a predefined transmission frequency such that the output voltage of the corresponding resonator of the input circuit can be increased.

How when we are in a Doubt or Hesitation, whether to go this Way, or that Way, a secret Hint shall direct us this Way, when we intended to go that Way; nay, when Sense, our own Inclination, and perhaps Business has call'd to go the other Way, yet a strange Impression upon the Mind, from we know not what Springs, and by we know not what Power, shall over-rule us to go this Way; and it shall afterwards appear, that had we gone that Way which we should have gone, and even to our Imagination ought to have gone, we should have been ruin'd and lost: Upon these, and many like Reflections, I afterwards made it a certain Rule with me, That whenever I found those secret Hints, or pressings of my Mind, to doing, or not doing any Thing that presented; or to going this Way, or that Way, I never fail'd to obey the secret Dictate; though I knew no other Reason for it, than that such a Pressure, or such a Hint hung upon my Mind: I could give many Examples of the Success of this Conduct in the Course of my Life; but more especially in the latter Part of my inhabiting this unhappy Island; besides many Occasions which it is very likely I might have taken Notice of, if I had seen with the same Eyes then, that I saw with now: But 'tis never too late to be wise; and I cannot but advise all considering Men, whose Lives are attended with such extraordinary Incidents as mine, or even though not so extraordinary, not to slight such secret Intimations of Providence, let them come from what invisible Intelligence they will, that' I shall not discuss, and perhaps cannot account for; but certainly they are a Proof of the Converse of Spirits, and the secret Communication between those embody'd, and those unembody'd; and such a Proof as can never be withstood: Of which I shall have Occasion to give some very remarkable Instances, in the Remainder of my solitary Residence in this dismal Place.

有时，我们会陷入无所适从的境地，踌躇不定不知道该走哪条路才好。这时候，内心常常会出现一种暗示，指示我们走这条路，虽然我们原来想走的是那条路。不仅如此，有时我们的感觉、愿望、或我们的任务明明要我们走那条路，可是心里忽然灵机一动，要我们走这条路；这种灵机也不知道是从哪里来的，也不知道出自什么影响，可就是压倒了原来的一切感觉和愿望，使我们走这条路。结果，后来的事实证明，如果我们当初走了我们自己想走的路，或者走了我们心目中认为应该走的路，我们则早已陷于万劫不复的境地。反复思索之后，我自己定下了一条规矩：每当自己心里出现这种神秘的暗示或冲动，指示我应做什么或不应做什么，我就坚决服从这种神秘的指示，尽管我不知道为什么该这么做或该这么走，我知道的只是心里的这种暗示或冲动。在我一生中，可以找出许许多多这样的例子，由于我遵循了这种暗示或冲动而获得了成功，尤其是我流落到这个倒霉的荒岛上以后的生活，更证明了这一点。此外还有许多例子。当时我若能用现在的眼光去看待，是一定会意识到的。但是，世上有许多道理，只要有一天能大彻大悟，就不算太晚。我奉劝那些三思而后行的人，如果在他们的生活里，也像我一样充满了种种出乎寻常的变故，或者即使没有什么出乎寻常的变故，都千万不要忽视这种上天的启示，不管这种启示是什么看不见的神明发出的。关于这一点，我不准备在这里讨论，也无法加以阐明。但这种启示至少可以证明，精神与精神之间是可以交往的，有形的事物和无形的事物之间是有神秘的沟通的。而且，这种证明是永远无法推翻的。关于这一点，我将用我后半生的孤寂生活中一些很重要的例子加以证明。
