Results The inductivity of stem was the highest about 55.56%,but callus of leaves could not be induced.6-BA was the most important factor on callus induction,followed by 2,4-D NAA and sucrose.

结果茎段的诱导率最高，为55.56%，叶片诱导不出愈伤组织。6-BA是叶下珠愈伤组织形成的主要影响因素，2，4-D、NAA、蔗糖次之。

This promoter was used to construct an induction expression vector for monocotyledon (pC1300WDREB) with transcription factor gene of stress resistance and hygromycin phosphostransferas gene.

用该启动子与抗逆相关转录因子基因和潮霉素磷酸转移酶标记基因一起，构建成单子叶植物诱导表达载体pC1300WDREB。

It is similar with normal induction motor with high efficiency and power factor while operation with the adoption of parallel star-shape connection and nonparticipation of appended interspaced resistor. During starting stage the adoption of unique serial triangle connection with the participation of appended interspaced resistor improves the starting performance with the character of low start current and high start torque.

它正常运行时，采用并联星形连接，使得中间附加电阻不参与运行，其运行性能类似于普通感应电动机，具有较高的效率和功率因数；而在起动时，采用独特的串联三角形连接，使得中间附加电阻参与运行，相当于转子电阻增加，从而有着起动电流小、起动转矩高的优良的起动性能。

Potent synergism between vascular endothelial growth factor and basic fibroblast growth factor in the induction of angiogenesis in vitro.

MMF对狼疮性肾炎及其它血管炎显著的疗效提示血管内皮细胞有可能是它的效应器官之一［1，2，16］。

Statistic analysis indicated that the main factor which influenced callus induction and the inducting rate of fasciculated shoots were explant, the optimal medium for callus induction was MS+1.0mg/L BA+1.0mg/L NAA+0.5mg/L 2,4-D+Leaves.

论文摘要：采用正交设计方法，研究了6-BA、NAA、2，4-D及外植体4种不同因素及其组合对钟花樱愈伤组织及丛生芽诱导率的影响，试验结果统计分析表明：外植体是诱导愈伤组织和诱导丛生芽的最主要因素。

Expanded MSCs were induced to differentiate into nerve cells withthree different treatment protocol in the prensent study . On the following day, the medium was replaced with preinduction medium consisting of DMEM, 20% FCS, and 10 ng/ml basic fibroblast growth factor. After 24 h, the preinduction medium was removed, the cells were washed twice with PBS, and neuronal induction medium containing DMEM supplemented with 2% DMSO and200 m bu-tylated hydroxyanisole was added. In later experiments, we used DMEM with 5 mM p - mercaptoethanol or sulfo - glycerine as an alternative neuronal induction medium for the same incubation.

将待诱导分化的MSCs按0.4x10~6／ml接种于事先放置有消毒盖玻片的六孔板内制备细胞爬片，分别采用三种不同的方法诱导第2代至10代的MSCs向神经细胞分化，即方法1先用含bFGF的培养基进行预诱导，之后再用含叔丁基对羟基茴香醚，和二甲亚砜的无血清培养基进行诱导；方法2和方法3用B-巯基乙醇和硫代甘油进行预诱导，然后不同浓度的上述物质进行正式诱导。

In particular, induction generators cannot support the system voltage during faults, unlike steam or hydro turbine-driven synchronous generators (however properly matched power factor correction capacitors along with electronic control of resonance can support induction generation without grid).

特别是，感应发电机不能支持系统电压故障期间，与蒸汽或水轮机驱动的同步发电机（但是适当匹配功率因数校正电容器以及电子控制的共振可以支持新一代无网格感应）。

Second chapter has analyzed the international direct investment position choice fundamental factor, the IT industry industrial characteristic and the IT industry multinational corporation international investment position choice strategy, has carried on the induction to the IT industry international direct investment position choice primary factor.

第二章分析了国际直接投资区位选择的基本因素、IT产业的产业特征和IT产业跨国公司国际投资的区位选择战略，对IT产业国际直接投资区位选择的主要因素进行了归纳。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
