There are chiefly two models explaining the S4 movement: the helical screw (S4 move translationally and rotationally in a gating canal which is composed of part of the channel protein), and the paddle model (S4 lying at the channel periphery and moving as one unit with S3b).

本文即藉由S3与S4间之连接段(S3-4 linker)和S4本身之非碱性胺基酸的突变，来探讨S4在去极化时移动的方式与距离，以及包围在S4外侧之主要电阻区的环境与位置。

As a species, Ms Turkle thinks, we run the risk of letting the permanent wireless social clouds that surround us steal part of our nature.

特克尔女士认为，作为物种之一的人类正冒着让包围我们的永久无线社交层偷走我们部分天性的危险。

I hoped that the air strikes, along with our success in relieving the siege of Sarajevo, would convince the allies to take a stronger posture toward Serb aggression in and around the embattled towns of Tuzla and Srebrenica as well.

我希望这次空战，以及我们在解除萨拉热窝包围上的成功，会说服我们的盟友采取更为强硬的态度对付塞族人在图兹拉和斯雷布雷尼察市内或周围的攻势。

Listen, boy, I was with Drake in Judith, his fifty tonner, at San Juan de Ulua when we and Admiral Hawkins—he was in Minion—when we fought our way out of harbor through the dung- eating Spaniards.

&听着，孩子，我自己曾经和德拉克一起在圣·胡安·德尤尔出海，乘坐他的五十吨位的&朱迪斯号&战船，一起航行的还有当时的海军上将霍金斯的&米尼安号等——我们一起从该死的西班牙船队包围下杀开血路出港。

And Justice Rehnquist— though bareheaded and ill, pitifully underclad for the cold , with his tracheotomy tube wobbling at his throat— was basking in the climate he had helped to create.

而伦奎斯特法官－尽管没戴帽子而且病了，令人同情的被寒冷包围，做了气管切开术他的喉咙上还插着摆动着的软管－对于他协助建立的思潮感到舒适。

At the super-low permeable reservior sandstone of Fu and Yang in Daqing Oilfield, many pore throats exist a lot in the types of compacted and restored flakes and curved lamellas while the pore volume of micropore and the thin, compacted and shrunken throat that contribute little to flow take large scale in the total pore space. Thereof high filtrational resistance is caused by much trouble including high content of reservoir shale, serious sensibility to pressure at waterflooding, remarkable effects of undersaturation and water blocks in micropore. A method with laboratory experiment, theoretical confirmation and field application included was adopted to analyze the non-linear flow characteristics, to reveal the deep mechanism of pinhole enveloping macropore and to provide a new technology of improving the development effect. The outcomes aquired are as follows: Multiple cores with different low and super-low permeability were selected to perform seepage experiments by gas, water and oil. Three fields of flow were observed in the reservoir at different low and super-low core permeability. They are pseudo- elastic flow, transition flow and plastic creep flow. So the concept that there was no correlation of rocky absolute permeability with fluid properties that pasted itself was broken up. Two-phase seepage of water displacing oil in uniform super-low permeability shows that the two-phase seepage zone is narrow.

针对大庆油田扶、杨特低渗透油层砂岩孔隙喉道的大小和形态以压实再生型片状、弯片状喉道分布较广，压实、缩小型细喉道型，微孔不可流动的孔隙体积所占总孔隙体积的比例较大的特点；及储层泥质含量高，注水开发中压力敏感性强、微孔隙欠饱和及水锁效应显著，导致流体渗流阻力增大的问题，本文采用室内实验、理论推证和矿场应用相结合的方法，研究、分析了流体非线性渗流特征，更深刻地揭示出小孔包围大孔的机理及产生原因，并提供了改善开发效果的新的技术方法，取得如下成果：选择不同渗透率的低渗透、特低渗透岩心，进行了气、水和油单相渗流实验，揭示出当岩心渗透率不同时，油层内的流体呈现出拟弹性流变、过渡流变、塑性蠕变三种流变区，从而打破了岩心的绝对渗透率与通过岩心流体性质无关的观点；同类特低渗透岩心的水驱油两相渗流实验表明，两相渗流区较窄。

The latter part of October was the time when this guerilla warfare reached its height. That period of this warfare, in which the irregulars were themselves amazed at their own audacity, were every moment in dread of being surrounded and captured by the French, and never unsaddling, hardly dismounting, hid in the woods, in momentary expectation of pursuit, was already over.

这是战争的第一阶段，在这一阶段，游击队自己都为他们的胆大而吃惊，他们时刻提防着被法军活捉或者被包围，因此，他们总是马不离鞍，人不离马，隐藏在森林里，俟机袭击敌人，现在，这一阶段已成为过去。

The analysis result shows that the remaining oil of this area is characterized as: Remaining oil is mainly distributed in thin tabulated beds and untabulated beds with low permeability. Remaining oil scatters widely. Complexity exists in the contact between remaining oil and water flooded layers and zones. Vertically, the remaining oil layers in adjusting area alternates with water breakthrough layers, between them the barrier beds is thin. Horizontally, because of the plane heterogeneity, the relatively good intervals are flooded, so that the remaining oil only exists in margin oil layer owing to faultiness of injection-production; remaining oil is enclosed by waterflooded zone, therefore, it is so complex relationships between remaining oil and waterflooded layers and zones that high requirements are made in the choice of completion optimization.

通过研究分析，研究区二类油层剩余油具有以下特点：(1)剩余油以表内薄差层和表外层为主，渗透能力低；(2)剩余油比较零散；(3)剩余油与水淹层和水淹带的接触具有复杂性；调整区剩余油从纵向上看，剩余油层与见水层相间分布，隔层小；从平面上看，由于油层平面的非均质性，相对较好部位已水淹，只在油层的边边角角部位由于注采不完善等因素存在剩余油，剩余油被水淹带包围，所以目前剩余油与水淹层和水淹带的接触相当复杂，这对完井方式的选择提出更高的要求。

The situation of abnormal development of male cells is as follows:microspore mother cell can't enter into meiosis because of intense vacuolation,shrink and disintegration of its cytoplasm;although vacuolated microspore mother cell can enter into meiosis,it can't form normal dyad and degenerate in the middle process;dyad and tetrad become vacuolated and can't develop normally;cytoplasm of microspore shrinks around the nucleus at the stage of central nucleus microspore,the shape of microspore is twisted into crescent or irregular shape,at last its cytoplasm and nucleus are disintegrated and crescent vacant microspore presents;nutritive substances can't be accumulated at the stage of vacuolated microspore,cytoplasm is disintegrated,and microspore turns into a big vacant pollen.

雄性细胞异常发育有几种情况：小孢子母细胞强烈液泡化，细胞质收缩解体，不能进入减数分裂；小孢子母细胞液泡化，虽能进入减数分裂，但不能形成正常二分体而中途退化；二分体、四分体细胞液泡化，不能进行正常发育；单核小孢子中央期，细胞质收缩包围核，小孢子形状扭曲呈月牙形或不规则形，最终细胞质和核解体而呈月牙形的空壳小孢子；单核液泡期的小孢子不能积聚营养物质，细胞质解体而成为大的空壳花粉粒。

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
