复合纳米纤维长丝束制备装置及其制备方法是一种简单、高效电纺制备纳米纤维长丝束的方法，其步骤为将料液输送给支架(3)上的电纺喷头对(1)；喷口相向的电纺喷头对(1)的每个喷头分别施加相反极性的直流高电压；每对相向喷口喷出分别带相反电荷的纳米纤维，并在空中相互吸引、碰撞形成复合纳米纤维，经牵引、拉伸后形成复合纳米纤维长丝束；第一对相向放置的电纺喷头纺丝形成的复合纳米纤维长丝束向下拉伸，并作为接受体与第二对电纺喷头喷出的分别带相反电荷并相互吸引的纳米纤维在空中相遇，被第二对电纺喷头喷出的纳米纤维包裹，经牵引、拉伸后形成两层复合纳米纤维长丝束；依次类推，最后经导丝辊对(2)牵引、拉伸后得到多层复合纳米纤维长丝束。

The gel dynamics experiments showed that the gel formation law was similar with the other polymer systems, which wasrelated with dense surface under the soft coagulating condition and the thickening gel; the square of gel thickness was linear with coagulation time. The qualitative analysis of the surface puckers of fibers spun from wet spinning and dry-jet wet spinning was made. The positions where the die swell appeared were not the same and the die swell appeared at the air gap where the fiber would markedly been elongated and vary little in the coagulant, thus the surface of fiber spun from dry-jet wet spinning was more smooth. The radial component concentration gradient was responsible for the radial structure of PAN fiber spun from dry-jet wet spinning. The thicker surface with microvoid structure of

对湿纺和干湿纺进行比较表层沟槽的产生进行定性分析，原因在于孔口胀大区域出现在不同位置，在干湿纺中，溶液的孔口胀大出现在空气层，并在该区完成大部分形变，进入凝固浴后形变很小，纤维表面较为光滑；干湿纺PAN纤维径向结构存在差异，这与丝条内组分由于双扩散进行导致径向上存在浓度差异直接相关；凝固强度较大的体系，可以获得厚度较大且孔结构尺寸较小的皮层；含较少缠结的PAN原液在纤维成形后截面很圆整，但原液缠结浓度增大时成形后圆整度下降；PAN纤维成形是一个远离平衡的过程，凝固作用缓和的体系可以使成形过程靠近平衡，可获得更大尺寸的孔洞结构；原液中少量的非溶剂添加剂显著改变纤维径向结构，可获得孔洞尺寸更小和更为均一的径向结构，这与径向浓度差异的减小、分相时间的集中相关；PAN原液的成形纤维表面依赖于凝固强度；由AFM对相近凝固条件下成形的PAN膜进下

Correct makes the law forms the good personal hygiene habit, sufficient sleep, attendance in exercise, reduced pressure, enough nutrition; The attendance washes the hands, after particularly has contacted the public goods, must wash the hands first touches own eye, the nose and the mouth again; Sneezes and cough time should use the paper goods to cover the oronasal; The indoor maintains ventilates and so on..

众所周知，人类感染后的类型A型H1N1禽流感的症状和感冒相似，患者会出现发烧，咳嗽，疲劳，有食欲不振等在预防方面，许蕤桁认为，现阶段没有必要挤在一起vaccinates流感疫苗的人，因为防止季节性流感疫苗，以防止型A型H1N1禽流感，而不是有效果正确的法律形式作出的良好个人卫生习惯，充足的睡眠，参加行使，减少压力，足够的营养；出席冲洗手后，特别是已与公共物品，必须先清洗双手触及自己的眼睛，鼻子和口再次；打喷嚏和咳嗽时应该使用文件的货物，以支付口鼻；室内保持通风等等如果我们用正确的方法预防它，它就不会那么可怕这里有一些为你的建议：首先，当你在咳嗽或者打喷嚏的时候，你应该用手捂着嘴然后你最好尽可能的离公共场所远一点严重强迫症的治疗，如果你必须去，请戴上口罩饭前仔细洗手，经常打开窗后这样使空气保持清新最后你应该做更多的运动去使你身体更强壮，这样你就可以保持健康了我认为这才是最重要的

The edgewise technique was used to align and level the upper and lower arches gradually and upright the lower incisors. Then, modified LeFort Ⅰ osteotomy was operated with 4 cases pterygomaxillary disjunction and the other 2 cases not. The maxillas were not moved during the operation and sutured mucoperiosteum at the same place. After 3-5 days latency period, elastic distraction about 700g/side and increasing to 1400g/side gradually, was started with two cases which the maxillas were not cut off totally.

术后经过3—5天的延迟期即开始牵引，2例行不完全截开术者，采用弹性牵引，力量从700g／侧逐渐增加至1500g／侧；4例行完全骨截开术者，首先采用刚性牵引和口外牵引钩，每天缩短牵引钢丝1mm，2例直接达到矫治要求，其余2例达到浅覆盖后，截去口外牵引钩，换弹性牵引和口内牵引钩继续前牵上颌骨。

Cases happened in 76 cases suffering the not prophylactic terminal ileum stoma patients and the patients was concrescence after treating with colon transversum stoma, abdomen-perinaeum association ectomy, nutrition and partly washing.

未施行预防性末端回肠造瘘的76例患者中吻合口瘘发生率11.896（9例），分别予以横结肠造瘘、腹会阴联合切除术及营养支持与局部冲洗引流治疗后愈合；出现吻合口瘘后的平均住院时间为27（15-60）天。

Hand-folded four-Pack (50g/mdoes-quadratical and the following paper) or hand-fold three fold (60-80g/m-squared paper) in a manner worthy of the books which should be in the book-to-last three fold in a manner worthy of the fold sewup hemomediastinum, to rule out the air and in a manner worthy of the book to prevent wrinkles appear, but now there are many flats in manual folding, knowing very well that should be hemomediastinum, but the pursuit of production would go for the big is not hemomediastinum, and finally after the wrinkles in buchbinderei and unrectifiable is extremely serious.

手工折四折（50g/m平方及以下的纸张）或手工折三折（60-80g/m平方纸张）的书帖均应在书帖倒数第三折折缝上破口，以排除书帖内空气而防止皱褶出现，但现在有许多单位在手工折页时，明知应破口，但一味追求产量就是不破口，最后书籍装订后皱褶极为严重而无法补救。

Some Britons have dismissed the anger expressed by American politicians of all stripes on the grounds that the United States, too, has courted Mr Qaddafi (Barack Obama's special envoy to Sudan lavished praise on Libya not long after Mr Megrahi flew home); that it cozies up to unsavory partners in Saudi Arabia and elsewhere; and that after Abu Ghraib and Guantánamo it is in no position to preach.

但是，部分英国人却对美国各派政客的恼怒之情不以为意，因为在他们看来，美国也在奉承讨好卡扎菲先生（迈格拉希先生乘机回国后不久，巴拉克？奥巴马的苏旦事务特使就对利比亚满口谀辞）；美国与沙特阿拉伯及其他国家和地区的一些难缠的盟友之间眉来眼去；阿布格莱布和关塔纳摩虐囚事件曝光后，美国已没资格满口仁义道德了。

一种淤泥陶粒生产的预烘干工艺，其特征在于它包括如下步骤：1准备回转钢笼：回转钢笼由旋转架(1)、钢笼(2)、旋转驱动机构构成；2将回转钢笼置于陶粒煅烧回转窑的尾部，将回转窑通风所产生的热尾气由钢笼(2)低端口导入钢笼(2)的空腔通道中；启动回转钢笼的旋转驱动机，旋转驱动机驱动旋转架(1)旋转，带动钢笼(2)旋转；待预烘干的陶粒生料球从钢笼(2)的高端口进入钢笼(2)的空腔通道中，陶粒生料球在钢笼(2)的空腔通道内翻转时与由钢笼(2)低端口导入的热尾气充分接触，从而迅速烘干水分；烘干后的陶粒生料球从钢笼(2)低端口排出。

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。
