闭口

When the termination pressure in the reversible adiabatic expansion process is equal to that in the irreversible adiabatic expansion process, the external work in the former is equal to the expansion work, however that in the latter is less than the expansion work.

指出了文献[1]中关于闭口系统不可逆绝热过程分析存在的问题，认为闭口系统绝热膨胀过程对外所作的功等于热力学能降，而非膨胀功等于热力学能降。

If he should really be guilty,' said he,'and did really put in to the Island of Elba; if he is really charged with a letter for the Bonapartist committee at Paris, and if they find this letter upon him, those who have supported him will pass for his accomplices.' I confess I had my fears, in the state in which politics then were, and I held my tongue.

假如他真的有罪，'他说，'真的在厄尔巴岛上过岸，假如他真的负责带了一封信给巴黎的拿破仑党委员会，假如他们真的在他身上搜到了这封信，那么那些帮他说话的人就将被视为是他的同谋，'我很害怕，当时的政治状况充满着隐伏的危险，所以我就闭口不讲了。

He always cham up when we ask aboot his family.

我们一问到他的家庭时，他总是闭口不言。

Owing to the use of better crushing frequency and eccentric distance, thus the content of fine graininess is much higher, and the content of the granularity less than the discharge opening on closing edge may reach 80%.

由于采用了较佳的破碎频率和偏心距。使破碎产品中细粒级含量更高小于闭口边排料口粒级的含量可达80％。

In Laplace space, the exact element stiffness matrix of the axial, torsional and bending vibrations of cone-shaped and symmetrical closed thin-walled bars are derived. By use of variation principle, the element stiffness matrix of the coupling vibrations of an asymmetrical closed thin-walled bar is also given.

在拉氏空间中导出了锥形杆件和对称闭口薄壁杆件的轴向、扭转和弯曲振动的精确单元刚度矩阵，应用变分原理也给出了非对称闭口薄壁杆件耦联振动的单元刚度矩阵。

For example, self-cleaning by current-heating provides clean cap surface and stable FE characteristics; a capped CNT can be opened controllably.

比如清洁闭口管的表面，从而获得稳定的发射；或可控地打开闭口管的&帽子&。

First,it mainly utilizes analytics to deduce formula of slot leakage reactance.It considers three instances,including monolayer-slot,multilayer isometric-slot and multilayer anisometric-slot.Then,the analytics and the FEM are utilized to calculate slot leakage reactance of stator winding of prototype of Powerformer and compare their results.Second,the theory of utilitzing FEM to calculate the reactance of Powerformer is simply introduced,including stable reactance,transient and subtransient reactance.Specially,the saturated influence of the stable reactance is considered.Then, the results are analysed.Final,it mainly introduces the influence of harmonic magnetomotive force of stator winding and analyses the harmonic magnetomotive force of stator winding.

首先是用解析法推导出Powerformer定子绕组槽漏抗的计算公式，考虑了单层圆形半闭口槽、多层等半径圆形半闭口槽和多层不等半径圆形半闭口槽三种情况，并对Powerformer样机的定子绕组槽漏抗用解析法和有限元法进行了计算，并比较其结果；其次，简要介绍了有限元法计算Powerformer电抗参数的原理，包括稳态电抗、瞬态电抗和超瞬态电抗，对稳态电抗考虑饱和影响，对结果进行分析；最后，介绍定子绕组谐波磁势对电机运行性能的影响并对定子绕组谐波磁势进行了分析。

So November 15th I took her daughter with her husband came to live in Shenzhen, it is so, we are a family of three lived together in Shenzhen for some time, this time a good husband to me, makes no reference to the past, sad thing, he went to work early in the morning, around 21:00 in order to work while still caring for Internet cafes, Sunday seldom idle, but he also has a total taking more time to accompany us and her daughter to shop, but also occasionally helped me wash clothes under.

于是11月15号我就带着女儿跟老公来到的深圳生活，就这样，我们一家三口一起在深圳生活了一段时间，这段时间老公对我很好，闭口不提以往的伤心事，他一早就去上班，晚上9点左右才能下班，一边还要照看网吧，星期天也很少空闲，但他也还总抽出些时间陪我们母女逛逛街，还偶尔帮我洗下衣服。

Free float steam trap is only half of a semi-float type of ball bucket for moving parts opening down the ball bucket that is open and close cases but also seals.

ziyou半浮球式疏水阀只有一个半浮球式的球桶为活动部件，闭口朝下，球桶即是启闭件，又是密封件。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
