The number and distribution of the singular points of streamlines in the cross section of steady flow through a curved tube are discussed by using the method of topological structure analysis.

利用拓扑结构分析方法，分析了弯曲圆管内定常流在横截面上流线的奇点个数及分布规律，给出了二次流的漩涡数目由 2个变为 4个，流态结构发生分叉现象的理论判据·进而，利用Galerkin方法，得到了弯曲圆管内定常流的流函数和轴向速度的半解析表达式，给出了流态结构发生分叉现象的临界Dean数，所得结果与理论判则一

Generally, it can be divided into three types of floating stress, spindling stress and pressing stress, among which floating stress is the most important.

血管内流体压力的突然升高，在血管分叉处产生涡流；液体在血管内流动对管壁产生不同的应力，一般分流体切应力、轴向应力和压应力3种，其中流体切应力最为重要。

Template-confined growth is a very powerful method for obtaining aligned 1D nanomaterials with adjustable diameter, length and morphology. Porous anodic aluminum oxide templates with different channel structures have been synthesized in our lab, with which the aligned CNT arrays, Y-branching and novel dendriform CNTs have been obtained. Based on the structural characterization of the products, a space-limited and self-catalytic growth mechanism has been proposed accordingly. Roughly speaking, the catalyst particles at the bottom of template channels initiate the nucleation of carbon species, which acts as the seed for subsequent CNT growth.

本文采用近年发展起来的模板控制生长法，以多孔氧化铝模板控制CVD生长的方法调控了碳纳米管有序阵列、γ-分叉及树枝状分叉结构，在对产物进行详尽结构表征和分析的基础上阐述了氧化铝模板控制生长碳纳米管的生长机制：孔道内催化剂仅在生长初始阶段催化碳物种的成核，起&种子&作用，随后模板孔道自身的催化及限域作用使碳纳米管紧贴着孔道内壁生长。

At the root canal therapy process, hidden in the root canal isthmus, bifurcation area, triangle, shape and irregular dentinal tubules within the Enterococcus faecalis prepared by mechanical means it is difficult to remove, it can be biofilm, proton pump tolerance mechanisms such as root canals harsh ecological environment, to avoid conventional drugs, the role of disinfection, resulting in the failure of root canal therapy.

在根管治疗过程中，隐藏在根管峡部、分叉区、三角区、形态不规则区及牙本质小管内的粪肠球菌难以用机械预备的方法去除，它可通过生物膜、质子泵等机制耐受根管内苛刻的生态环境，躲避常规消毒药物的作用，从而导致根管治疗的失败。

Any of various other nocturnal songbirds of the genus Luscinia.

感夜性属的各种蝙蝠，特征是鼻管延长并分叉。

Any of various fruit bats of the genus Nyctimene distinguished by nostrils drawn out into diverging tubes.

感夜性属的各种蝙蝠，特征是鼻管延长并分叉。

All specimens are of small size, mostly less than 150 μm in diameter. In gross morphology, those problematical microfossils consist of stout tubes with closed base, tiny internal mold of elongated tube, parallel clustered unbranching tubes, spicule-like structure with expanded circular base, and branching tubes of various bifurcating styles.

作者在处理陕南末元古纪的化石过程中，发现了大量不同形态的微体管状化石(直径大多小于150μm)，包括末端封闭的粗短管体，不分枝管体，末端扩展的骨针状构造及具多种分叉样式的分枝管体。

Methods: The microanatomy of these interspaces was studied in 8 sides of human cadaver specimen with sphenoid approach. Seven cases of pituitaries and four craniopharyngiomas were diagnosed by MRI, which were removed bit by bit through the interspace superior to the fork of internal carotid artery and the first to the fourth interspaces in skull base.

在8侧尸体头上采用翼点入路观察颈内动脉分叉上间隙的显微结构；并对磁共振诊断为大型垂体瘤7例及颅咽管瘤4例者，采取翼点入路、联合应用颈内动脉分叉上间隙及颅底第1~4间隙，行瘤内减压、逐步切除肿瘤。

The results show that, influenced by the rarefaction waves from the left sharp corner, the reaction zone is separated from the leading shock. Then, the detonation is degenerated into the deflagration. The winkled reaction front can be clearly identified in numerical schlieren and temperature contours.

结果表明：气相爆轰波在分叉管中传播，分叉口左尖点的稀疏波导致诱导激波后压力、温度急剧下降，诱导激波和化学反应区分离，爆轰波衰减为爆燃波。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
