Disk absent. Ovary ovoid, cylindrical, or bottle-shaped, glabrous or hairy, many loculed; ovules numerous per locule; styles as many as carpels (15-30), usually reflexed, persistent, radiating, in functionally female flower elongating after anthesis; rudimentary ovary in functionally male flower very small, with minute styles.

The primers and the detection programs have been used to detect the pathogens in the inoculated-diseased cucumber plants .The details are reported as follows: 1. By using the primers ITS1/ITS4, only Fusarium isolates could be amplified to produce a special fragment of 750bp. This product generated 480bp, 200bp and 100bp fragments after digested by restriction enzyme HinfⅠonly from the pathogen of Cucurbits Fusarium Wilt.

引物ITS1/ITS4只在镰孢属菌株上扩增到一条750bp分子片段，其他供试菌株无扩增条带产生，扩增产物经HinfⅠ酶解后，只有瓜类尖镰孢菌产生480bp、200bp和100bp 3条带，说明该PCR-RFLP程序对瓜类尖镰孢菌具有特异性；巢式PCR引物BIK1/BIK4和BIK2/BIK3只有在黄瓜尖镰孢菌菌株上扩增到一条800bp分子片段，其他菌株均无扩增条带产生，说明该巢式PCR程序对黄瓜尖镰孢菌具有特异性。

On bright, calm days they lie in thousands on the now darkening water, mostly yellow flotillas of poplar, floating continuously down from great trees that themselves shake in the windless air with the sound of falling water , but on rainy days or after rain they seem to swim or be driven away, and nothing remains to break the surface except the last of the olive-yellow lily pads that in high summer covered every inch of water like plates of emerald porcelain...

当风和日丽时，无数的树叶浮在已经变暗的湖水上，大部份都是白桦叶子，他们一批一批，像黄色的小小扁舟，不断地从高高的树上飘落下来，在无风的空气中轻轻地晃动着，发出如同流水而下的声音。但是在下雨的时候，或者雨过之后，那些浮在湖面上的落叶，仿佛鱼儿一样都游走了，又像是被不知什么驱赶一空，湖面上除了最后的几片黄绿色睡莲叶子，再无一物，而在盛夏里，那些睡莲叶子，如同翠绿晶莹的瓷盘，覆盖着每一寸湖面。

The theory can also be used in the computation of thin, medium-thick and thick plate in elastic foundation.

建立了Winkler地基及双参数地基上Mindlin中厚板的无网格法分析理论，将EFGM法、RKPM法、NEM法这三种无网格法应用于Mindlin中厚板弯曲问题，推动了弹性地基上中厚板计算理论的发展。

A broad expanse of the river was turned to blood; in the middle distance the red hue brightened into gold;,through which a solitary log came floating ,black and conspicuous; in one place ,a long slanting mark lay sparkling upon the water; in another the surface was broken by boiling ,tumbling rings, that were as many-tinted as an opal; where the ruddy flush was faintest ,was a smooth spot that was covered with graceful circles and radiating lines, ever so delicatedly traced; the shore on our left was densely wooded ,and the somber shadow that fell from this forest was broken in one place by a long, ruffled trail that shone like silver; and high above the forest wall a clean-stemmed dead tree waved a single leafy bough that glowed like a flame in the unobstructed splendor that was flowing from the sun. there were graceful curves ,reflected images ,woody heights ,soft distances ; and over the whole scene ,far and near ,the dissolving lights drifted steadily ,enriching it every passing moment with new marvels of coloring.

还记得自己刚开始船上生涯时所见过的那次辉煌的落日：宽阔的河面一片血红；不远处这红色明亮起来，变成金色，一根显眼的黑色圆森木从中漂过；这边，一根长长的浮标倾斜在水面上，熠熠闪光；那边，翻滚的波浪打破了宁静的水面，像猫眼石般色彩纷呈；微红的水流最缓和处，美丽的涟漪在平稳的水面上层层荡漾开去；左侧的河岸上丛林茂密；一条如银带般闪亮的小径从昏暗的树荫中蜿蜒而出，伸向远处；高高的密林之上有一根无枝无蔓的枯树，仅留有一根带叶的树枝在风中晃动，在太阳一泻千里的光辉里，它宛如燃烧的一团火；还有优美的波纹、水中的倒影、树木葱茏的高地、柔和的远景；放眼望去，由远及近，逐渐裉去的光线随波荡漾，每时每记得都以其新的奇妙着色为这条河添姿增彩。

Anhydrous plate wash An anhydrous alcohol, a water-free alcohol used in lithographic deep-etch platemaking to wash the plate before applying tie lacquer image base.

无水洗版液是无水酒精。在制深蚀版时用来清洗版面，然后在印纹基样上涂上假漆。

The condensing tower comprises a gravity settling chamber where a set of loading trays is fixed, wherein the middle-lower part of the condensing tower mounts a round condenser tube, of which the upper and lower ends is connected with a sieve pore type baffle, in manner of closest arrangement based on the round section. The upper part of the condensing tower comprises a spherical cover without hem, a pre refrigerating chamber, a gas pipe type refrigerated trap, and the lower there of is a passive cold trap.

冷凝塔包括重力沉降室，沉降室内安有一组承料盘，冷凝塔中下部有按圆截面最紧密排列的方式设置圆形冷凝管，冷凝管上、下端联接有筛孔状隔板；冷冻塔上部分包括无折边球形塔盖，预冷冻室和气管式冷冻捕集器，下部分为无源冷阱捕集器。

Nickel-Titanium instruments have become widely used in the endodontic treatment. However, their unexpected separation was a serious concern in endodontics. To date, no scientific methods have been developed to evaluate the functional lifespan of Ni-Ti instruments. In this study, we used resonance frequency analysis to nondestructively detect the fatigue life of Ni-Ti instruments to determine the feasibility of this technique for use in the clinic.

镍钛合金根管锉已经广泛的使用在牙髓病的治疗上，但其无预警的断裂也是令牙医师关心的问题，之前并无一科学性的方法来评估镍钛合金根管锉的寿命，而本研究室利用自然频率的分析方式对镍钛合金根管锉做非破坏性的疲劳检测，确定此方式可行且在临床上有应用的价值。

Finally, the prints are laminated on line-free and acid-free cardboard, giving them a genuine archive feel. The results are museum-quality photographs with long-term durability that will bring pleasure to their owners for many years to come.

接著再上一层可让照片持久保存的特殊涂剂，最后再将之护贝在无痕的无酸纸板上，呈现出一种博物馆级的展览质感，这将带给收藏家无比的观赏和收藏的乐趣。

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。
