The following experimental results are obtained:(1) Through the dissociation and ionization of sodium amide in a shock tube with a magic hole to provide sodium ions and electrons, the three-body recombination rate coefficient of sodium ion with electron is determined under the condition of argon atoms acting as the third body in the collision process:〓. The experimental temperature range is from 1400 to 2700K, extending the limitation of the flame method.

实验获得了如下结果：（1）在魔洞型单脉冲激波管上以氨基钠粉的高温分解和电离提供钠离子和电子，测定了以氩原子为碰撞第三体时钠离子与电子的三体复合速率系数〓，实验测量温度范围1400～2700K，拓宽了火焰方法测量结果的局限。

In addition, they have relatively longer flower tubes, higher stigmatic pollen loads, bigger pollen size and a shorter blooming period for individual flowers. Finally, the author discusses the evolutionary significance of floral design in genus Pedicularis.

如我们发现，由柱头特征不同导致传粉效率的差异，这种传粉效率与马先蒿属植物的花冠管成正比，与单花开放时间成反比，与花粉大小成正比，本文还着重讨论了这些相关性的适应性意义。

By adding some fluorescence group in the reaction,we can utilize the fluorescence signal to accumulate and monitor the whole PCR process,and finally through the standard curve,we could analysis the unknown sample.As this technology has the characteristics of strong peculiar,high sensitivity,fine repetitiveness and accurateness,fast and totally closed raction,so in diagnosing animal virosis,this technology not only can measure the power and distribution of pathogen infection in the organism,and also it still has sensitive,fast,convenient characteristics.

该技术实现了PCR从定性到定量的飞跃，同常规PCR法相比，该方法特异性和可靠性更强，能实现多重反应，且采用了完全闭管检测，不需PCR后处理，有效解决PCR污染问题以及EB对试验人员的伤害；再配以相应的荧光PCR仪，使整个PCR过程实现自动化，加之具有耗时短，操作方便等特点而备受推崇，因而广泛应用于基因表达研究、转基因产品安全检测、单核苷酸多态性研究及病原体检测等领域。

The flower has calorie of power, sepal egg shape wraps around needle form, petaline corydalis is lubricious, have canaliculus state, straight or go up a bit curved; Florescence 4 ～ May, purple floret, xie Rengqing of after autumn bine is green be like first, the companion other the flower has acicular small fruit, till at the beginning of the winter, ground upside divides ability wither, because this is wonderful ground by the plant, but sheet is planted the predestined relationship issues a Zhi Yulin or on the meadow of exposed to the sun, also but with other herb, wait like bison grass, dandelion mix kind, form level ground of beautiful compose flowers and plants.

紫花地丁叶基生，狭披针形或卵状披针形，边缘具圆齿，叶柄具狭翅，托叶钻状三角形，有睫毛。花有卡柄，萼片卵状披针形，花瓣紫堇色，具细管状，直或稍上弯；花期4～5月，紫色小花，秋后茎叶仍青绿如初，花旁伴有针状小果，直至冬初，地上部分才枯萎，因此是极好的地被植物，可单种成片植于林缘下或向阳的草地上，也可与其他草本植物，如野牛草。蒲公英等混种，形成漂亮的缀花草坪。

METHODS: Sixty-two patients with symptomatic degenerative lumbar spinal stenosis were treated with single-level instrumented posterolateral lumbar fusion.

60例出现临床症状的退行性腰椎管狭窄的患者采用单节段的腰椎后外侧融合术。

Besides the normal shape of myelin figures, single, double or even super helixes were found when the electrolyte concentration increased.

随着电解质浓度的增加，除通常的囊管结构外，还出现了单螺旋、双螺旋甚至超螺旋的结构。

To explore the potential application of boron nitride nanotubes in chemical sensor devices, we investigate the adsorption properties of the pristine and silicon doped (8, 0) single-walled BNNTs towards the toxic gas cyanogen chloride molecule by performing density functional theory calculations.
