母体

What scientists call "the fraternal birth order effect", the fact that each successive boy born to the same mother has a greater chance of being gay, may be due to an increasing immunological response by a mother's body to each male foetus in her womb.

科学家称之为"兄弟出生顺序效应"的一种现象，是指同母所生的每个男孩比其上一个亲生哥哥是同性恋的概率要大，这可能源于母体对自身子宫里每个男性胎儿的免疫反应强烈程度逐渐上升。

Any of numerous usually free-swimming marine coelenterates of the class Scyphozoa, characteristically having a gelatinous, tentacled, often bell-shaped medusoid stage as the dominant phase of its life cycle.

水母，海蜇大量的、经常自由游动的真水母类腔肠动物，胶质的、带有触须的、常为钟形的类水母体阶段是其生命循环中的主要形式

The mothers confined to the diet consisting of both Fucus and Pilayella grew better and produced larger egg mass than those having consumed Fucus alone.

The methacrylic acid, TRIM and SDBS were used as functional monomer, polymeric matrix and dispersant respectively.

本文以Cu2+为印迹离子，以MAA为功能单体，TRIM为聚合物母体，以SDBS为分散剂，利用反相乳液-悬浮聚合法制备了Cu2+印迹聚合物微球。

Statistical methods designed specifically for mapping QTL controlling endosperm trait have been proposed by several researchers in recent years, but these methods all ignored the influence of the maternal genom.

谷类作物种子的整个发育过程是在母体植株上完成的，母株为种子提供库容和营养，因此种子胚乳性状和胚性状的遗传表达除了受胚乳和胚自身基因型控制以外，还可能受到母株基因型影响。

Hairy roots were induced from tobacco leaves with Agrobacterium rhizogenes LBA1334 harboring agropin type PRil855 and binary vector PIG121HM carrying a kanamycin resistant gene nptll and GUS gene and the good hairy root clones were selected. The root with many root hairs and branches grew vigorously toward all the direction on MS medium without plant hormone and on kanamyain containing medium (km:30mg/L). The structure of the hairy root tip is different from that of ordinary root. Witch was not typical root cap maybe the main cause of losing the geotropism of hairy root. Plantlet regenerated from hairy root when cultured on Ms medium without plant hormone. The nicotine content of the hairy root was little higher than that in the natural roots.

本研究通过发根农杆菌工程菌LBA1334(含有野生型pRi1855质粒和pIG121HM双元载体质粒，编码NPTⅡ基因和GUS基因)转化烟草沙姆逊，获得了具有卡那霉素抗性烟草发状根，并筛选出良好的单克隆株系，该发状根具有典型的发状根特性(多根毛、多分支、在无激素培养基上快速生长)，通过根尖压片分析，烟草发状根不具备典型的根冠；发状根中烟碱含量1.61％稍高于与天然栽培品种母体根的含量(1.5％左右)，发状根向培养液中释放烟碱，释放量最多时占总烟碱量的81.1％；在无激素的培养基上获得了再生植株。

Calcic phosphor is the bases of form ossification road and tooth, both lacks fetal skeleton with respect to development undesirable, bring about gibbosity, the mother's body still can give view cramp, osteoporosis.

钙磷是形成骨路和牙齿的主要成分，二者缺乏胎儿骨骼就发育不良，导致软骨病，母体还会出观抽筋、骨质疏松。

Both slag and scale can be found as elongated or globular inclusions in base or weld metal.

焊渣和鳞片在母体金属或焊缝金属中都能以伸长的或球状的内含物形式存在。

据 介绍，在彗星世界里，最著名的就是哈雷彗星了，四大流星雨之一的宝瓶座流星雨的母体彗星就是哈雷彗星。

Culture is the mother of science and technology, and it is the economy and society development herald.

文化是科学技术进步的母体，是经济社会发展的先声。

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.
