We observed that a majority of dsRNA was localized in the nuclear periphery discontinuously after 24 hours of transfection. Time course showed that the labeled dsRNAs were maintained in cultured silkworm cells for up to 5 days. After six days, the signal was too weak to be detected.

用荧光显微镜观察FAM标记的dsRNA在细胞内的定位，发现在转染24小时后，dsRNA开始越来越多的聚集在细胞核的周围，并呈不连续分布，细胞内的荧光强度也越来越强。dsRNA在家蚕细胞中可以维持5天的时间，但到第6天时细胞内已检测不出荧光信号。

Stability of implants was measured by rfa regularly.results there was no significant difference between both groups about stability at all periods and histomorphometry, but isq, bic and ba of experimental group were higher than control group, and isq recovered more quickly in experimental group after loaded.conclusion dual threads design contributes to assure the initial and secondary stability of implants, which is particularly important in poor density bone.

结果 两组种植体在各时期的稳定度差异均无显著性，但在每一时期实验组种植体的稳定度均较对照组高，实验组种植体在负重后稳定度恢复较快，负重3个月后实验组的骨-种植体接触率和种植体周围骨面积均较对照组稍高，但两者差异无显著性。结论双梯形螺纹种植体有利于保证种植体的初期和后期稳定性，应用于低密度骨质优越性会更加明显。

Mrs. RACHEL lynde lived just where the Avonlea main road dipped down into a little hollow fringed with alders and ladies' eardrops and traversedby a brook that had its source away back in the woods of the old Cuthbert place; it was reputed to be an intricate headlong brook, in its earlier course through those woods, with dark secrets of pool and cascade but by the time it reached Lynde's Hollow it was a quiet, well-conducted little stream, for not even a brook could run past Mrs.

雷切尔。林德太太住在阿冯利亚的大路和小山谷交界的地方，周围长满了赤杨和大红色的倒挂金钟。一条小溪横穿过山谷，它的源头在老卡斯伯特家的树林里；这条小河在流经树林的最初阶段，以众多的支流和莽撞的劲头而著称，一路留下无数隐秘的池塘和小瀑布。

For a monotone twist map the well-known Birkhoff fixed point theoremsays that the circles with rational rotation number will break up whence a finitenumber of pairs of periodic points arise,half of which are elliptic and the othershyperbolic.Moreover,around each elliptic periodic point a few of new invariantcurves will appear and make a picture of phase space with a self-similar structure.Again one may ask is there a similar picture for higher dimensional Hamiltoniansystems?

对于单调扭转映射，著名的Birkhoff不动点定理指出，在通有情况下旋转数为有理数的不变曲线一般会破裂，在原来的不变曲线附近会产生有限多对周期点，其中一半是双曲的，一半是椭圆的，而在椭圆型周期点的周围又会产生一圈圈的不变曲线，使得椭圆周期点附近的动力学行为和整个相空间的动力学行为十分相象，换句话说，整个相空间具有无限嵌套的自相似结构，自然又产生了一个问题：对于自由度数目大于2的高维哈密顿系统，其相空间是否有类似的图象？

The calculated results indicate that there are two absolutely opposite regions in the vicinity of 5-FU. In one of the regions, water molecules can assist the tautomerism from 5-FU to its enol form 5-FU(superscript *, whereas in another region, water molecules can protect 5-FU from tautomerizing to 5-FU(superscript *).

研究发现，在5-氟尿嘧啶周围存在两类不同的区域，在其中一类区域中，水分子能促进质子转移的发生；而在另一类区域中，水分子却能阻碍质子转移的发生。

Some parents may find their baby between his eyes to the right, and go to the hospital examination, doctors say that is not oblique. This may be the medical sense of epicanthus, also called pseudo-esotropia.

从婴儿的视力发育特点来看，孩子在出生2个月后，视力增强，已能注视周围的人和物，这时，婴儿如果睡在摇篮里，不能在距摇篮1.5米以内的空间摆设玩具、物件等任何东西。

The Lincoln hills rose up around me at the extremity of a snowy plain, in which I did not remember to have stood before; and the fishermen, at an indeterminable distance over the ice, moving slowly about with their wolfish dogs, passed for sealers, or Esquimaux, or in misty weather loomed like fabulous creatures, and I did not know whether they were giants or pygmies.

在我周围，林肯的群山矗立在一个茫茫雪原的四极，我以前仿佛并未到过这个平原；在冰上看不清楚的远处，渔夫带了他们的狼犬慢慢地移动，好像是猎海狗的人或爱斯基摩人那样，或者在雾蒙蒙的天气里，如同传说中的生物隐隐约约地出现，我不知道他们究竟是人还是倸儒。

The flotation mechanism of MG reverse-floating dolomite was studied by measuring the Zeta-potential of collophanite and dolomite, Infrared Absorptions Spectra analysing the adsorption of MG onto the minerals surface, ultraviolet- visible light absorbing spectrum calculating the amount of MG which was adsorbed onto the minerals surface. These researches showed that MG was more easyly adsorded onto the surface of dolomite in feeble acidic solution because of pure dolomite charges positive as well as pure collophanite charges negative. Therefore, a lot of MG negative ions was adsorded onto dolomite, and that MG negative ions contained hydrophobic group, the hydrophobicity of dolomite was modified, the grains of dolomite were adhered to air bubble and float with them.

对白云石和胶磷矿的Zeta-电位测定、红外光谱分析MG药剂在矿物上面的吸附情况、紫外-可见吸收光谱测定矿物上MG的吸附量等，研究了MG药剂反浮选白云石的浮选作用机理，表明在弱酸性条件下，由于白云石表面荷正电而胶磷矿表面荷负电，带有羧基和羟基官能团的MG药剂更容易吸附在白云石上，使其周围吸附有大量的MG负离子，而MG负离子的另一端为烃基，这就改变了白云石的疏水性，使其矿粒容易附着于气泡上浮。

"With credit frozen and the commercial paper market poised on the brink of collapse, this is the most promising development I've seen on Wall Street in months," said floor trader Tim Formato, one of hundreds who gathered around the $1 bill and excitedly called their clients to inform them that they were looking at actual U.S.

" 在这信贷冻结外加商业票据市场濒于崩溃的边缘的时候，看到这个消息是几个月来我在华尔街遇到的最富希望的事件了，"场内经纪人提姆。佛马托说道。他是在场的数百名幸福者中的一员，这些经纪人聚集在这张1美元纸币周围，兴奋地打电话给他们的客户，告诉客户他们场内经纪人都正在凝视着真正的美国货币。

"I wish I had a photo to share of this very true story but any ponder with cats has likely had the same experience at some time or another. Several years ago, when I was enjoying the second season of my first pond (I have now built four as I've moved around), one of our cats,"Smokey", who was a natural hunter in her prime, saw a mockingbird alight on a lilly pad to get a drink of water. Well, old "Smokester slowly crept out from under some day lillies and made a spectacular jump with all four paws majestically carrying her like a flying squirrel, right for that intruding bird.

"我真希望我的照片分享这个非常真实的故事，但任何思考与猫狗都有可能有相同的经历，在某个时候或另一几年前，当我在享受第二个赛季的我的第一个池（现在我已经建成4个，作为我已经让周围），我们的一个猫"的smokey "，他们是非常自然的猎人，在她风华正茂，看到一只知更鸟下车，就来垫，以获得喝水，那么旧的" smokester 慢慢来逐步脱离，有一天声声，并提出了壮观的跳跃与所有四个熊掌majestically进行，她像一个飞鼠，右为入侵的鸟。

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。
