螺旋形成

Pollen cones terminal, solitary or clustered in leaf axils, or borne in spikelike complexes; individual cones pedunculate or sessile; microsporophylls numerous, spirally arranged, with distinct adaxial and abaxial surfaces; microsporangia 2; pollen 2(or 3)-saccate in Chinese species,.

雄球花单个顶生，或者在叶腋簇生，或者形成穗状复合花序；雄球花有花序梗或者无；小孢子叶许多，螺旋状排列，背腹面显著；小孢子囊2个；中国的种类的花粉2 (-3)气囊，。

The thiopeptides, by binding within a cleft located between the ribosomal protein L11 and helices 43 and 44 of the 23S rRNA, overlap with the position of domain V of EF-G, thus explaining how this class of drugs perturbs translation factor binding to the ribosome.

核糖体蛋白L11和23SrRNA的43/44螺旋结构形成裂隙，L11的构象变化能够加宽该裂隙从而允许延伸因子EF-G插入，促使GTP水解，为肽链延伸合成过程中核糖体的构象变化提供能量，而Thio能够与L11和23sRNA结合，阻止L11的构象变化，使该裂隙处于闭合状态，抑制EF－G在延伸过程中的作用。

Other types of millipedes may curl into a looser, sloppier spiral or form a neat ball.

在同样情况下，其他种类的千足虫可能会蜷缩成较为松散的螺旋形圆盘，或者形成溜圆的圆球。

The straight section and the spiral section form a single continuous cable, not two sections spliced together.

直线段和螺旋段形成单根的连续光缆，而不是两段接合在一起。

Currently has a long auger, lime machine, High Pressure Jet Drilling Rig, strong drill Roofbolter more than 10 varieties of five series.

目前已形成长螺旋钻机、灰土桩机、高压旋喷钻机、强冲钻机、锚杆钻机五大系列10多个品种。

For example,the spiral arrangement of scale－bract complexes on ovule－bearing pine cones,where the female reproductive organs of conifers are located,is important to the production of airflow patterns that spiral over the cone's su***ces,thereby passing airborne pollen from one scale to the next.

例如，带有胚珠的松球的鳞苞综合体的螺旋状安排，亦即松柏目植物雌性殖器官的所在位置，对于气流模式的形成与产生殊为重要，而这些气流模式在松球的表现盘旋上升，从而把在空气中飞行的花粉从一个鳞苞传播至下一个鳞苞。

Material is fed into the inner cylinder of the feeding scroll through a feed pipe and into the solid-bowl after the acceleration.

物料由进料管连续引入输料螺旋内筒，加速后进入转鼓，在离心力作用下，较重的固相物沉积在转鼓壁上形成沉渣层。

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
