分枝成

Say the word 'cactus,' and many people get a mental picture of a thick, straight up trunk with rounded tip, and sturdy branches curving to the vertical in a candelabra effect.

当我们提到"仙人掌"，很多人脑子里会有一个粗壮、笔直的圆顶躯干，结实的弯曲成枝状大烛台一样的分枝的仙人掌形象。

In constant acceleration growth, a retard effect of response of eu-tectic interflake spacing on the growth rate has been observed.

在加速生长过程中，共晶相间距对生长速度的响应呈滞后效应，响应机制是共晶Si相成簇分枝和局域"终结"延伸。

Hsüopsida is parallel to the above three plant categories in Early Devonian and differs from them in that: the trimerophytes or Euphyllophytina have long fusiform sporangia terminating in trusses and P-type tracheids; the zosterophytes or Lycophytina are characterized by the exarch xylem; the rhyniophytes bear simple isotomous branches and S-type tracheids.

徐氏蕨类群与上述早泥盆世的三大类群并行，它不同于三枝蕨类或者是真叶植物的长纺锤形、成簇顶生的孢子囊和P-型管胞；不同于工蕨类或石松植物的外始式木质部；不同于莱尼蕨类植物简单的等二叉分枝和S-型管胞。

Dichotomy Forked branching produced by division of the growing point into two equal parts, seen for example in Fucus.

由于主轴顶端的原始细胞分裂成两个生长点，均等的长出两个分枝形成的叉状分枝。

Lower glume not separated by an internode; spikelets in pairs and clustered toward the ends of the branches.

更低的颖片不被一节间分开；成对的小穗和对于分枝的末端的簇生。 5 P。 bisulcatum 糠稷

Results:(1)The NPY neurons are typically small and medium neurons with triangular or spindle-shaped perikaryons. Most of them have 1-3 slender, poorly ramified primary dendrites.

结果：(1)NPY和POMC神经元在形态上存在明显差异，典型的NPY神经元细胞体较小，成三角形或纺锤形，大部分具有1-3个细小的，不分枝的一级树突。

Leaf blade oblate to 5-angled or oblate to orbicular-ovate, apex often 3-lobed, base often truncate or subcordate; spikes well branched into subpanicle.

叶片扁球形到具5个角或扁球形到圆形卵形的，先端通常3浅裂的，基部通常截形或近心形；穗状花序多分枝成近圆锥花序 16 B 。

The artery ramifies into a network of veins.

动脉分枝成许多网状的静脉。

The artery ramifies into a network of vein s.

动脉分枝成许多网状的静脉。

"Unlike the hair of most mammals, feathers do not cover the entire skin surface of bird s but are arranged in symmetrical tracts alternating with areas of bare skin, which may contain the small, soft feathers called down."

典型的羽，由中心羽轴和连续成对的羽枝，构成扁平而通常略曲的羽瓣－－翮。羽枝具有进一步的分枝－－羽小枝，相邻羽枝的羽小枝是由钩相互连接，使翮更坚挺。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
