偶而

The length of certain bond and the number of conjugate double-bond affected OWFπ-π greatly, OWFπ-π changed linearly with the change of bond length (for planar azobenzene derivatives and cyanine derivatives) and the change of conjugate double-bond number (for conjugate alkene, p-carotene and lycopene).

3键长和共轭双键数对OWF_有较大的影响，OWF_随键长(如平面型的偶氮苯衍生物、菁类和氧杂菁类等)和双键数(如共轭烯烃类、β—胡萝卜素和番茄红素等)的变化而线性变化。

3 Recently, we reported an efficient tin-free version of this reaction involving thiophenol for the preparation of cyclopentane derivatives through a 1,5-hydrogen transfer/cyclization sequence [Eq.(1); AIBN=azobisisobutyronitrile].

最近，我们报道了高效的、不使用锡试剂而使用苯硫酚的反应，这个反应是通过1，5-氢转移/环化步骤制备环戊烷衍生物的[化学反应式(1)；AIBN=偶氮二异丁腈][4]。

Obviously, divorcement rate is very high in recent years, and a lot of people don't want to marry.

畸于人而侔于天，以人为畸与天为偶，不与人打交道，和天是好朋友。

The nights of the New Year break belong to fireworks, an ear-splitting, eye-popping carnival of mass pyrotechnics that begins on New Year's Eve night and runs, with occasional lulls, until the Lantern Festival that ends the traditional holiday period 15 days later.

华尔街日报》中国新闻编辑Jason Dean报道。白天是这样的，但春节假期的夜晚，却是烟花爆竹的世界。一场震耳欲聋而又让人叹为观止的大型焰火狂欢，从除夕夜开始，中间偶有缓和，一直持续到15天过后的元宵节，至此传统节日才宣告结束。

While the guanine anion has a character of dipole-bound state,and its fragmentation is not sensitive to the low energy electron attachment.

而鸟嘌呤的阴离子具有偶极态束缚的特征，其碎片化过程对电子附着并不敏感。

Configuration feature: Constant green small tree, gao Keda 8m, bark brown gray, crack, branch is arranged loose, ramose from bottom to top gradually short, establish body tower look, big branch up or bend downward slightly, rod is long and straight, up extend, 4 arris form, close top shows a circle, it is scale leaf completely, scale leaf hands in each other opposite on rod, clingy rod, see 3 impeller are unripe occasionally, scale leaf grows 1.5-3.5mm, pointed or tip acute is blunt, small incurvate, without candle pink, have gland system, gland body is elliptic, be located in a leaf back radical ministry, individual plant of different of male and female, rare with individual plant.

科 属：柏科。圆柏属。形态特征：常绿小乔木，高可达8m，树皮褐灰色，条裂，枝条排列疏松，分枝自下而上渐短，树体塔形，大枝向上或略向下弯曲，小枝长而直，向上伸展，四棱形，近顶端呈圆形，全为鳞叶，鳞叶在小枝上交互对生，紧贴小枝，偶见三叶轮生，鳞叶长1.5-3.5mm，先端锐尖或钝，微内曲，无蜡粉，有腺体，腺体椭圆形，位于叶背基部，雌雄异株，稀同株。

Results showed that Aha logogriphs elicited a more negative ERP deflection than did No-aha logogriphs in the time window within 1400-1700 ms (LNC1), 1700-2000 ms (LNC2) and 2000-2500 ms (LNC3) after onset of the logogriph. Dipole analysis localized the generator of LNC1 in the left Gyrus frontalis superior, LNC2 in the left frontal cortex and LNC3 in the posterior cingulate cortex.

对差异波进行偶极子溯源分析，结果显示，在1400-1700 ms内该负成分(LNC1)主要起源于左侧额中回(BA 9)附近；在1700-2000ms内，该负成份(LNC2)可能主要起源于左侧额叶(BA 4)；而在随后的2000-2500ms，该负成分(LNC3)可能主要起源于PCC(BA 31)附近。

RESULTS: The microscopic observation showed chondrocytes in the transducted group proliferated stably, and triangle, and spindle cells were predominant in the seventh passage, accompanied by few long-spindle and root cells. In addition, the cells were of clear appearance and large lucency. However, in the non-transducted group, long-spindle cells were observed in the fourth passage, and almost all cells exhibited long-spindle shape in the fifth passage.

结果：①倒置显微镜观察，转导组兔关节软骨细胞生长增殖稳定，至第7代仍旧以三角形、梭形及纺锤形细胞为主，偶见长梭形和树根形细胞，且轮廓清晰，透亮度大，折光性强；而未转导组细胞培养至第4代时即己出现长梭形细胞，自第5代细胞形态几乎全部变成长梭形。

Among them Al_(11)La_3 photograph is accumulated as a result of lesser cathode face, to quickening its all round of magnesian matrix corrode do not remove apparent effect; and area of cathode of lumpish Al_8LaMn_4 photograph is larger, form small couple to corrode with matrix, quickened matrix corrode.

其中Al_(11)La_3相由于较小的阴极面积，对加速其四周镁基体的腐蚀不起明显功能；而块状的Al_8LaMn_4相阴极面积较大，和基体构成微电偶腐蚀，加速了基体的腐蚀。

他的画中往往没有什么明确具体的形，而只有一些线条、一些形的胚胎、一些类似于儿童涂鸦期的偶得形状。

Methods: Five patients with parkinsonism or dystonia were assigned to general anesthesia using an modified endotracheal tube.
