Results: No differences were observed in the incidences of postdural puncture headacheafter spinal anesthesia with or without pillow support. There were significantly less neck stiffness and significantly improved patients satisfaction in the study group.

研究结果：实验组及控制组在脊髓麻醉后PDPH发生率，在统计上并无显著差异，但在肩颈酸痛程度和麻醉病患满意度方面，统计结果：为实验组肩颈酸痛程度(1.57分)小於控制组(3.23分)；而麻醉病患满意度调查结果为实验组的8.07分，高於控制组的满意度调查结果7.95分，虽两组平均分数差异不大，但统计结果皆为 p＜。05，表示实验组和控制组在统计上有差异。

In order to prvoide the new clue for the later tapping oil potential of maturing oilfiled, especially for the stratagem adjustment of high water-cut inefficient exploitation reservoir, and prolongate the realm and orientation of tapping oil potential, the waterflooding characteristics and the law of remaining oil distribution were studied.

结果表明，该块油层水淹程度仅80%左右，剩余油在平面上分布于区块的绝大部分区域，且与构造高低无明显关系，纵向上主要集中于层段的上部，尤其是位于该块西北区构造低部位的北断层区潜力单元，是与目前老油田潜力区主要局限于正向型微构造区所不同的新类型与新领域。

Results were as follows: in MS basic medium+KT2mg/L or 2ip, the two varieties growed well. Appending NAA0.2 mg/L could promote radication commonly. But in MS+BAP2 mg/L there was obvious difference from the two varieties. Chinese yam rhizome axillary bud was restrainted. But feng yam was prone to form fascicular bud. When supplemented with NAA0.2 mg.L-1, NAA and BAP could accelerate Chinese yam rhizome axillary bud growth and increase the number of buds.

结果表明：两品种在MS+KT2mg/L或2ip培养基上生长情况均较好，当附加NAA0.2时，一般可促进生根；但在培养基上，两品种差异明显，淮山药表现腋芽生长受抑制，而凤山药则易形成丛生芽，而当此培养基附加NAA0.2时，NAA与BAP可协同作用促进淮山药的腋芽生长，增加芽苗数，但对凤山药的生长则基本无影响。

Conclusion. No significant differences in radiologic and clinical outcome were found, in either group. Both procedures appear to be safe and effective surgically and radiographically.

两组病例在影像与临床疗效上无明显差异，两种治疗在手术方式与影像上均为安全及有效的术式。

Long branch is rufous, show "" the glyph bends, smooth, have stipular thorn or not apparent; Short branch is born in the each other on the long branch of biennial above; Fall off sexual rod is finer, without bud, bunch is born on short branch, after autumn and foliaceous all fall.

长枝红褐色，呈&之&字形弯曲，光滑，有托叶刺或不明显；短枝在二年生以上的长枝上互生；脱落性小枝较纤细，无芽，簇生于短枝上，秋后与叶俱落。

By analyzing the strange behaviors of massless integrations in dimensional regularisation, It was proposed that for a special kind integration, which is sero mathmatically, should not be simply treated as sero physically, as a fact it is the difference of the same magnitude ultraviolet divergence and infrared divergence.

通过研究维数正规化中的无质量积分的奇妙特性，本文指出对一种特殊类型的动量积分，从数学上看DR给出的结果为零，但物理上不能把结果简单处理为零，而是反映了大小相等的紫外和红外发散之差。

There were differences in peer relation and classroom structure among male students of sociometric statuses, while there were no such differences among female students of sociometric statuses (3) perceived interpersonal harmony by students was positively correlated with their prosocial behaviors, but were uncorrelated with aggressive behaviors; peer relation was negatively correlated with shyness-sensitivity.

2在男生组中，不同社会测量地位学生在班级人际和谐的同伴关系和班级组织上有显著的差异。而在女生组中，不同社会测量地位学生在班级人际和谐的各个维度上均无显著性差异。(3)学生感知到的班级人际和谐与亲社会行为之间存在显著正相关，学生感知到的人际和谐与攻击行为之间相关不显著，感知到的同伴人际和谐与儿童的羞怯－敏感性有显著负相关。

Different chemicals have different spectrographic signatures, but those of water and hydroxyl are very similar. Therefore, the scientists can't exactly distinguish whether it is a hydroxyl or water at this point. Nevertheless, the findings overturn long-held beliefs that the surface of the moon was dry and further pave the way for scientists to one day set up a permanent research base on the moon.

不同化学成分会有不同的光谱特徵，但是水和氢氧根的光谱特徵却十分相似，因此科学家目前还无法确实判断月球上的成分到底为氢氧根还是水，尽管如此，这项发现颠覆了长期以来月球表面无水的认知，且更进一步地为科学家将来有一天能於月球上设置长驻研究基地铺路。

An unusual isolate from watercress mottle,in association withturnip mosaic and cucumber mosaic viruses,produced small white local necrotic lesions on sapinoculated leaves of Nicotiana tabacum,N.rustica,N.glutinosa,Datura stramonium,Solanumnigra,Brassica pekinensis,B.chinensis,B.campestris,Raphanus sativa,Nasturtium officinale,Spinacia oleracea and Amaranthus mangostanus while small brown local necrotic lesions onGomphrena globosa,Phaseolus vulgaris,Dolichos lablab...

在北京香山樱桃沟野生的十字花科豆瓣菜上发现有芜菁花叶病毒、黄瓜花叶病毒以及一种未报导过的&小白斑&病毒的复合病。小白斑病毒在20多种寄主上，包括十字花科，单独汁液接种时只能产生局部坏死病斑，不能系统侵染；单独接种而能系统感染的寄主有百日菊，只产生极轻微的深浅绿花叶，甚至有时几乎无病状。小白斑病毒能在复合病情况下系统存在于豆瓣菜中是值得注意的一种现象。

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.
