根轴

Ratio of the external leaf surface to its volume was smaller in psammophytes than in mesophytes.

轴器官中普遍具有发达的机械组织，一些植物形成异常结构；根的周皮发达；茎中基本组织／半径比率较大；部分植物形成同化枝，有的茎、叶中存在粘液细胞或结晶。

Fittingly so, it is also the instance referenced by the root property of DisplayObject instances within that SWF.

主时间轴是影片的根，也是 SWF 中所有可视对象的 root 属性所引用的实例对象。

Axial distribution of activity ratio A ( 134 Cs)/ A ( 137 Cs) along the fuel rod with different burnup level,irradiation history and cooling time is measured by the γ scanning device. As a comparison, this distribution is calculated by the FCAC code used for the fuel rod failure analysis.

在热室中，用γ扫描装置对秦山核电厂 3× 3 -2考验组件中辐照历史、燃耗及冷却时间不同的两根燃料棒中的铯活度比A(13 4 Cs)/A(13 7Cs)的轴向分布进行了测量，并利用自行开发的压水堆燃料棒破损特性分析程序FCAC进行了理论计算。

In addition to this, shoots were differentiated on hypocotyl segments cocultivated with A.

除此之外，共培养后的下胚轴切段在发根的同时也分化出幼苗。

During development of the seedling, the hypocotyl forms the lower portion of the stem from the radicle up to the cotyledons

在幼苗发育期间，下胚轴从胚根到子叶的茎的下部形成。有许多形式的心理上的丑陋。

Desiccation tolerance of hypocotyl was larger than that of radicle.

下胚轴的脱水耐性大于胚根。

In the range of 20-40g/L, the growth rate of hypocotyl calli of A. crenata was positive to sucrose concentration.

在20-40 g／L范围内，朱砂根的下胚轴愈伤组织生长速率随着蔗糖浓度的升高而升高，50 g／L的蔗糖降低愈伤组织的鲜重增长率，但提高干重增长率。

During development of the seedling, the hypocotyl forms the lower portion of the stem from the radicle up to the cotyledon s

在幼苗发育期间，下胚轴从胚根到子叶的茎的下部形成。

In cotyledon, on one hand, very weak GUS staining was observed in PARF8:GUS, but very strong was found in phyA-209 PARF8:GUS. In the shoot apical meristem, hypocotyle and root tip, on the other hand, phyA-209 PARF8:GUS exhibited weaker GUS activity than PARF8:GUS. Interestedly the same expression patterns of ARF8 resulting from disruption of PhyA have been observed in dark, white-light and far-red-light conditions.

结果表明，无论在黑暗、白光和远红光条件下，PhyA突变均明显提高幼苗子叶和叶片中ARF8的表达水平，但明显降低幼苗下胚轴、茎尖和根尖中的表达水平。

Load spectrum determination of tubing inwall proves the tubing is acted by the axial alternating load in a rod pumped well, and all the fractures are located at the root of the tooth.

油管内壁载荷谱测定进一步明确了油管在工作状态下承受轴向拉-拉交变载荷，其断裂部位全部在应力集中的齿根处。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
