本研究以南京椴无菌试管苗的茎段、叶片、根系为外植体，进行器官发生研究，探讨了不同因素对南京椴直接器官发生以及愈伤组织诱导的影响。主要结果如下： 1。

While testing on mRNA transcripts of either SCY2 or scygonadin,respectively in bacterially challenged mud crab,it was found that there was no significant change of SCY2 and scygonadin mRNA abundance in all of the tested tissues,suggesting that bacterial infection can not induce the transcription of both SCY2 and scygonadin genes.

检测细菌感染条件下锯缘青蟹各组织SCY2及Scygonadin表达情况，发现在感染后48 h内，SCY2和Scygonadin mRNA在性腺组织中的表达水平均无明显变化，说明外部细菌感染不是SCY2的直接诱导表达因素。

Several factors on affecting wheat leaf calli induction and plant regeneration are studied.

研究了影响小麦叶片愈伤组织诱导及植株再生的因素。

In this work, the effects of culture factors ( MET, IBA, culture medium and culturing in dark) on root formation were studied in tissue culture of Celastrus angulatus. The results showed that the root induction was significantly affected by duration of culture in dark, while other factors were least effective.

探讨了培养因子对诱导苦皮藤试管苗生根的作用，采用正交试验设计法测试了苦皮藤生根关键因素多效唑、吲哚丁酸、暗培养及培养基中盐浓度的效应。

The best culture medium for root induction of Celastrus angulatus was that containing: 1/2 MS+MET3.0 mg.L-1+IBA 0.8 mg.L-1 or 1/2 MS+ MET3.0 mg.L-1 + IBA 0.5mg.L-1 for 12 days, in dark.

诱导苦皮藤组培苗生根的最佳因素配比为：1/2 MS+MET 3.0 mg.L-1 + IBA 0.8 mg.L-1和1/2 MS +MET 3.0 mg.L-1 + IBA0.5 mg.L-1，暗培养12 d效果最好。

In addition, experiments in vivo showed that tumor in mice growed faster after treatment of mice with chemotherapeutic drugs.

在此基础上，探讨混合肽诱导的特异性免疫与其它治疗因素联合的可能性及其机制。

OBJECTIVE: To explore the feasibility of in vivo chondrogenesis by co-culture of bone marrow-derived MSCs and chondrocytes.

背景：诱导因子及软骨微环境是影响骨髓基质干细胞成软骨分化及软骨形成的主要因素。

By dynamic observation of ARM occurrence in ETU treated rats, we found ARM related to the following factors:① Cloacal membrane was too short.② Cloaca configuration was abnormal.③ The tail groove did not form.④ Fusion of URS with cloacal membrane failed.

我们动态观察了ETU诱导的大鼠肛门直肠畸形的发生过程，发现肛门直肠畸形发生与下列因素有关：①泄殖腔膜过短；②泄殖腔构型异常；③没有尾沟形成；④尿直肠隔未与泄殖腔膜融合。

On the whole, 2 mg/L 2,4-D was found to be most favorable for the induction of embryogenic callli.

在影响胚性愈伤诱导的各因素中，2，4-D浓度直接影响愈伤组织的形态、生长和分化。

According to constraint-induced financial innovation theory, evadable financial innovation theory, the transaction cost innovation theory, and based on commercial banks" basic concepts and theory of intermediary operation"s development, in a comprehensive comparison between domestic and foreign commercial banks, this paper applies the econometric method of panel data to analyze 4 macroscopical indicators impacting on intermediary operation such as gross domestic product, per capita disposable income, total direct financing business and the average deposit and loan spreads, and the econometric method of time sequence to analyze 3 microcosmic indicators such as the rate of nonperforming loans, the rate of cash and assets, core capital adequacy ratio.

本文根据约束诱导型金融创新理论、规避型金融创新理论、交易成本创新理论等理论，以商业银行中间业务的基本概念和中间业务发展的理论依据为出发点，在全面比较国内外商业银行中间业务发展的基础之上，运用时间序列和面板数据分析方法，选择了国内生产总值、城乡居民人均可支配收入、企业直接融资总额和平均存贷款利差四个宏观经济变量以及不良贷款率、现金资产率和核心资本充足率三个微观经济变量，对影响我国国有商业银行中间业务发展的因素进行实证分析。

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.
