闭合

Most lesions of SD including bony deformities could be diagnosed with MRI. But the differential diagnosis of epidermoid between dermoid was still difficult.

MRI能正确、全面地诊断包括椎体畸形在内的大多数脊柱神经管闭合不全病变，但表皮样囊肿和皮样囊肿的鉴别仍存在困难。

The comparably slow operation of a disconnector leads to sparking during closing and opening in the contact gap.

由于隔离开关的开关动作相对较慢，在断开和闭合的过程中，触点间隙中会产生火花。

Leaves alternate, distichous or spirally arranged, sessile or petiolate; leaf sheath prominent, open or closed; leaf blade simple, entire. Inflorescence usually of cincinni in panicles or solitary, sometimes shortened into heads, sometimes sessile with flowers fascicled, sometimes axillary and penetrating enveloping leaf sheath, rarely flowers solitary and terminal or axillary.

叶互生，二列或者螺旋状排列，无柄或者有柄；叶鞘显著，开放或者闭合；单叶，全缘；花序通常为蝎尾状圆锥花序或者单花，有时缩短常为头状花序，有时无梗，花簇生，有时腋生，贯穿叶鞘，很少花单生，顶生或腋生。

The protic- or Lewis acid catalyzed ring-closure of divinyl ketones (and their acid-labile precursors) pentadienylic cations is known as the via Nazarov cyclization.

质子酸或路易斯酸通过戊二烯基阳离子催化二乙烯酮的环闭合（以及它们的酸不稳定前体）这个反应被称为Nazarov环化。

Dretske can thus use this notion of doxastic sensitivity to explain why closure fails by showing how knowledge needs to be understood relative to a certain relevant range of possible worlds which is variable depending upon the proposition at issue.

Dretske于是使用这个信念敏感性观点，解释了为什么闭合原则失败：知道需要被理解为相对于相关的一系列可能世界，而这些相关可能世界，会随着命题的改变而可以变化。

Today, there are like a book in 2009, after 365 days of the goods, reading, line to close, we have slowly come to listen to the footsteps of 2010, Dungan kind of "heavy water re-doubt trackless mountains, vista" relieved.

如今2009仿若一本书，经过365天的品读，行至闭合，我们已经聆听到2010姗姗而来的脚步，顿感那种&山重水复疑无路，柳暗花明又一村&的释然。

By measuring pressure induced by dynamiting which located various positions of the circular shell, the localizational effect of impact force on the circular shell is disclosed. Also, PVDF piezofilms are used to determine accurate time while projectile contacting target, accurate time while two interfaces of the target contacting at a initial distance of 5, and the contacting pressure between the two interfaces when the projectile is in 500m/s to lOOOm/s.

通过对化爆模拟加载试验中柱壳不同角度压力的监测，揭示了化爆模拟产生的压力局域化效应，为进一步模拟设计提出研究的方向；采用PVDF压电薄膜来监测弹靶碰撞的时刻、细小间隙的闭合时间以及由此产生的压力变化，通过对PVDF压力计测试结果分析以及和数值模拟结果的比较，获得规律性的认识，为进一步的应用提供了技术支持。

The plasmid DNA bands were detected clearly by agarose-EtBr gel electrophore sis.Two forms of plasmid DNA molecules,namely covalently closed circular DNA mol e-cules and open circular DNA molecules,were observed under electron microscope.

用琼脂糖-溴化乙锭凝胶电泳分析在两株菌的DNA中鉴别出明显的质粒带，用电镜方法在两株菌的DNA制剂中均观察到共价闭合超螺旋和开放型环状两种构型的DNA分子。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
