簇

The distributing of weed in the field is random and asymmetry.

杂草在田间的分布是随机的，不均匀的，而且具有簇生性。

Plant with erect leafy stems bearing clusters of rayless yellow flower heads on bent individual stalks; moist regions of southwestern United States .

有直立、多叶的茎和簇生的、无边花的、黄色头状花序；生在美国西南部潮湿的地区。

While undercooling at other temperatures, two or three events of recalescence may occur and the dendrite cluster may solidify.

其他过冷范围内的合金液则发生多次再辉和枝晶簇凝固。

Dendrite cluster mode of growth occurs during recalescence if Ni-32. 5%Sn eutectic alloy is undercooled by larger than 10k or 〓 and 〓 alloys are undercooled by less than 480k and 110k respectively.

共晶成分的Ni-32.5wt％Sn（△T大于10k）、非共晶成分的〓（△T小于480k）和〓（过冷度小于110k）等合金再辉过程中以枝晶簇方式凝固。

However, we can reconstitute the biosynthetic pathway by supplying the cells with catalytically active polypeptides.

但是，我们可以通过向细胞簇提供催化活性肽来重建生物合成的途径。

Are you the bed of roses sort of withered yet unique in passion, breathtaking, redden like raging flames?

你是那断红尚有相思字的蔷薇吗？花红如簇，旋缀遗魂。

The traits of dedifferentiation and redifferentiation of the explants form H. sampsonii show that the calli the stem and leaf usually form buds at its parietal cells. In the presence of auxin, the parenchyma of the leaf gap at the node is initiated firstly, then, develops blastemata that form buds in a cluster on the node without callus. These show that the various parts ofthe herb differ greatly in cell initiation and organ differentiation.

研究元宝草外植体的脱分化和再分化的特点结果表明，茎段和叶片启动形成愈伤组织，其不定芽通常发生在愈伤组织的周边区，茎节叶腋的叶隙薄壁组织在激素的诱导下启动、分裂，不形成愈伤组织而直接器官分化成芽原基，并在节结处产生一圈成簇的不定芽，表明元宝草不同部位的细胞启动及器官分化调控存在差异。

We brought forward theoretically the definition of refrangibility andstudied the nonlinear refraction and absorption of clusters based on the excited-state Z scan theory.

在理论上给出了折射度的定义，应用激发态Z扫描理论研究了团簇的非线性折射与吸收。

Structures and relative stability of medium-sized SiN clusters(21≤N≤50 and N=60).

中等尺寸SiN团簇结构和相对稳定性的研究(21≤N≤50，N=60)。

Flowers bisexual, protandrous, zygomorphic, resupinate to through 180° in axillary or subterminal racemes or pseudo-umbellate inflorescences, or not pedunculate, fascicled or solitary.

花两性，雄蕊先熟，左右对称，颠倒达180°度角，组成腋生或近端的总状花序或假伞形花序，或者无有花序梗，簇生或者单生。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
