Objective: Purpose to investigate the different in vitro function of targetable non-viral vector containing poly-L-lysine or protamine.

DNA-多聚阳离子-配体形成的复合体可以通过受体介导的内吞作用将目的基因靶向性导入含相应配体的细胞中［1］。

ResultsThrough a large number of the literature investigations,in the medicinal guides,some chemical constituents such as Platycodosides,3H-ligustrazine and aromatics,etc were found to have their own selectivity and the ability to actively enter the targetable sites, similar to the active target-tropism functions of primer, promoter, transmitter, mediator, transductor and transporter, etc.

结果经过大量的文献调研，发现引经中药中的某些化学成分如桔梗皂苷类、川芎嗪和芳香烃类等许多活性成分均有各自的主动选择性，能主动进入靶点部位，类似于引物、启动子、递质、介质、介导体、转导子、转运体等主动靶向性载体的功能。

Using cotyledon as explants to induce and differentiate callus, and a lots of resistent callus with green prominence were created, the completely differentiated transgenic alfalfa was not yet obtained.

利用农杆菌介导的叶盘法，选取子叶为外植体，现已获得大量的抗性愈伤组织，并且在愈伤组织上有绿色的突起，尚未得到分化完全的再生植株。

Huge thickness of lake facies deposit of Quaternary is developed in eastern Qaidam basin, in which the abundant microfossils such as ostracods, charophytes and gastropods are important evidences for analysis of stratigraphy and sedimentary environment.

柴达木盆地东部发育了巨厚的第四系湖相沉积，介形类、轮藻和腹足类等微体化石发育，是地层和沉积环境演化分析的重要依据。

Co-transformation of plasmid pGg-gfp and plasmid pCc1001 which harbors the complementary gene trp1 was conducted by the PEG-mediated protoplast transformation of the oidia of LT2, a tryptophan auxotrophic strain of Coprinus cinereus.

采用PEG介导法把表达质粒pGg-gfp与辅助质粒pCc1001（含有trp1基因）共转化进色氨酸营养缺陷型的灰盖鬼伞粉孢子的原生质体中。

A decrease in Qef value (x = 0 ~ 0.10) with increasing x was dominated by a decrease in the degree of 1:2 order. A increase in relative dielectric constant (x = 0 ~ 0.50) and the positively change of temperature coefficient of resonance frequency (x = 0.10 ~ 0.50) with increasing x were dominated by a decrease in the proportion of [NbO6] octahedra.

扭曲的 [NbO6] 八面体之比率主导本系统之相对介电系数随著 x 的增加而升高以及 x = 0.10 ~ 0.50之共振频率温度系数随著 x 的增加而往正的方向变动的趋势。

It should be noted that not only in the complex perovskite like BaO3,(X=Mg, Zn, Co, Ni, Mn: Y=Nb, Ta) but also in the compounds with tungsten bronze structure such as Ba6-3xLn8+2XTi18O54, they are consisted of corner-sharing oxygen octahedra and the ratios of ion in B site to ion in A site are usually larger than one.

值得注意的是业已开发出来的材料不论是复合钙钛矿BaO_3，(X=Mg，Zn，Co，Ni，Mn；Y=Nb，Ta)还是钨青铜结构，它们都是由氧八面体共顶连接，而且氧八面体内、外阳离子比例都等于或略大于1，因此，我们推测在B位与A位阳离子比例略小于1的类钙钛矿结构中极有可能存在具有优良介电性能的新材料。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
