纵向轴

With the advancement of technology, people's growing demand for the bar, its accuracy is also getting higher and higher, before people parallel roller leveler straightening tubes, rods and other circular cross-section of the build, round-wood in hand Direct the process of rotation is easy to produce, and only straightening roundwood roll axis perpendicular to the longitudinal section on the bend.

随着科技的进步，人们对棒材的需求量越来越大、对其精度要求也越来越高，以前人们采用平行辊矫直机矫直管、棒等圆形断面条材，圆材在矫直过程中容易产生自转现象，并且只能矫直圆材垂直于辊轴的纵向剖面上的弯曲。

Based on the generalized potential energy variational principal of nonlinear elasticity theory with large deflection, the incomplete generalized potential energy functional with large deflection is established on the space coupling free vibration of three-span self-anchored suspension bridge by considering the effect of axial compressive and shearing strain energy of stiffening girder.

摘 要：摘要：基于大位移非线性弹性理论的广义变分原理，考虑了加劲梁轴向压缩应变能和剪切应变能的影响，建立了三跨自锚式悬索桥空间耦合自由振动的大位移不完全广义势能泛函，通过约束变分导出了自锚式悬索桥的竖向挠曲振动、横向挠曲振动、纵向振动及扭转振动的基础微分方程，为自锚式悬索桥的固有振动性状分析提供可靠的理论依据。

Vertical sliding column valve is the use of a column in the shoulder of the slide valve body axial movement, so that the air intake on or off of.

纵向滑柱阀是利用一个有台肩的滑柱在阀体内轴向移动，从而使各气口接通或关断的。

Stamens usually 6 in 2 whorls, rarely 3 or 1, inserted on perianth, often unequal or dissimilar; filaments slender, free; anthers 2-loculed, introrse, dehiscing by longitudinal slits or rarely by pores; pollen grains 2- or 3-nucleate, colpi 1 or 2(or 3), distal or subequatorial.

雄蕊通常6，2轮，很少3或者1，着生在花被上，通常不等长或者不同；花丝纤细，离生；花药2室，内向，纵向开裂或少数孔裂；花粉粒2-3核， 1或者2(或者3)沟，远轴或者近赤道面。

Lute 鲁特琴（中文的琵琶也译做lute:A stringed instrument having abody shaped like a pear sliced lengthwise and a neck with a frettedfingerboard that is usually bent just below the tuning pegs.

一种纵向削制的形状如梨的拨弦乐器，琴颈上有定音档的指板，通常弯曲于调音单轴之下。

The second connecting member is capable of being positioned to be substantially coaxially aligned with the longitudinal axis and in ultrasound-transmitting physical contact with the first connecting member.

第二连接构件能够被定位成与所述纵向轴线基本上共轴对准，并且与第一连接构件超声传输物理接触。

Fruit a loculicidal capsule dehiscent from base or drupaceous and indehiscent, usually 2 seeds per locule; pericarp woody or fleshy; columella persistent.

果为室背开裂蒴果，自基部开裂，或具核果和不裂，通常种子每室2；果皮木质或者肉；轴柱宿存纵向的种子压扁，无翼；种皮多骨，光滑，发亮；种脐线；无胚乳。

Because the traditional research of vibration of shafting is on the basis of nonrelation among the torsional vibration, axial vibration and whirling vibration and carries out the calculation separately, the great difference between the calculating results and road-test results are led sometimes.

由于传统的轴系振动研究是以扭转振动、纵向振动、回旋振动互不联系为基础而分别进行的，从而导致有时计算结果与实测结果相差较大。

Inflorescence a raceme with 2 or 3(–6) spikelets, rarely a panicle with many spikelets, peduncle, axis, branches, and pedicels slender, glabrous, scabrous or pubescent along longitudinal angles, branches usually subtended by a scaly bract at base. Spikelets ± compressed at maturity, several to many florets; rachilla disarticulating below fertile florets, extended beyond palea of uppermost floret, internodes flattened or concave on side facing floret.

花序为一总状花序具2或3(-6)小穗，一圆锥花序具很多小穗，花序梗，轴，分枝和花梗纤细，沿着纵向的有棱的无毛，粗糙的或短柔毛的很少，成熟时的小穗多少压扁，数枚到多数小花；在肥沃的小花下面脱节的小穗轴，在最重要的小花的内稃以外延长，在边面对小花上节间被变平或者凹。

The main characters of this category are: 1 It possesses clear main axes and lateral branches/sporangial stalks; 2 Sporangia terminate the lateral branches or long stalks; 3 With the distinct dehiscing mechanism, the sporangia have the variation in shape, i. e. reniform, rounded or vertically elongate; 4 Primary xylem is of centrarch maturation; 5 Conducting tracheid is G-type.

该类群包括Hsüa，Renalia，Nothia，Sartilmania和Huia，其主要特征为：1）具有明显的主茎轴及侧出的分枝系／孢子囊柄；2）孢子囊顶生于侧枝上或侧生的长柄上；3）孢子囊性状存在变异，为肾形、圆形或纵向伸长，具明显的开裂机制；4）初生木质部发生顺序为心始式；5）G-型输水管胞。
