The domestic accessions exhibited high relatedness of root color within each sub-group. The accessions with red-coated root were nearly put into one sub-group, while the accessions with white and green-coated or white-coated root were put into the other sub-group.

国内种质的分类表现出了与根皮色密切相关的特征，基本上是根皮色为红色的聚为一个亚组，根皮色为白色和绿白色的聚为一个亚组。

Figleaf gourd and turban squash plants showed the highest dry weights, light-saturated rates of the CO_2 assimilation P_(Nsat and stomatal conductances at 14℃. Successively lower values for these measurements were observed at temperatures of 24℃and 34℃respectively.

上述六种温度敏感性不同的瓜类作物中，组Ⅰ在低根际温度下表现了最大的生物量、光饱和二氧化碳同化速率P_(Nsat与气孔导度，其次为中根际温度处理植株，以高根际温度处理植株表现最低。

When cultured on the medium with different auxin , root segments could elongate and branch, and the addition of 1mg/l IBA into the medium was the most suitable for long-term root culture. Calli could be induced from root explants in the presence of 2, 4-D and when transferred onto E medium, they transformed further into embryonic calli which could develop into normal plants through the stages of globular-embryo, heart-shaped embryo, torpedo-shaped embryo, cotyledonary embryo.

培养基中添加生长激素（IAA，IBA，NAA）能够诱导无菌苗根切段的生长和分枝形成；而1mg／l IBA的存在，最适合于根的长期离体培养。2，4-D的存在能够诱导根外植体脱分化形成愈伤组织，愈伤组织转移至E型分化培养基能够转变成胚性愈伤组织，并进一步经球形胚、心形胚、鱼雷形胚、子叶形胚发育成正常植株。

The effects of different cutting-root methods (time of the cutting, distance of cutting surface to stem base, and the numbers of cutting surface) and K top-dressing measures at later growth stage on K content in leaves of flue-cured tobacco plants were studied.

从断根时间、断根部位、断根数量、断根时追钾与否及追施钾素的形态等方面研究了不同处理及其组合对烤烟烟叶含钾量的影响。

ResultsThe root canals of 120 tooth were removed the filling and negotiated successfully,the 22 were failed.

结果成功去除原根管充填物及通畅根管120颗，22颗因出现侧穿、根管钙化无法扩通、器械折断而无法进一步治疗，维持现状或拔除。

Methods Sixty human teeth with single root were instrumented using step-back technique, then were divided into six groups and treated with different concentrations EDTA paste and NaClO solution.

选择60颗离体单根管牙，用逐步后退法预备根管，预备后随机分成6组，采用不同质量分数的EDTA糊剂对根管进行处理，分别为5%、10%、15%、17%和20%EDTA糊剂，另设生理盐水组作为对照。

Group 1 was instrumented with SS-K files by step-back technique, group 2 was instrumented with manual Protaper instruments according to manufacturers' directions.

第一组使用不锈钢K锉采用逐步后退法预备近颊根管，第二组使用手用Protaper采用厂家推荐的方法预备近颊根管，第三组使用机用K3采用逐步深入法预备近颊根管。

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。
