Studied on sensitivities of C. ellipsoidea to kanamycin , Chloromycetin , Hygromycin , Streptomycin and Geneticin (G418), the results showed that C. ellipsoidea is not sensitive to Km, Str and Cm, 600μg/ml km, 600μg/ml Str and 200μg/ml Cm can not inhabited the growth of C. ellipsoidea. However, it is fairly sensitive to Hm, 100μg/ml can completely stop the growth of C. ellipsoidea on solid media. We also found that C. ellipsoidea was highly sensitive to G418, 30μg/ml and 15μg/ml can inhabit the growth of C.

通过5种基因工程中常用抗生素对小球藻生长抑制的研究发现：小球藻对卡那霉素、链霉素、氯霉素不敏感。600μg/ml的卡那霉素、600μg/ml的链霉素和200μg/ml的氯霉素仍不能抑制小球藻的生长；小球藻对潮霉素较为敏感，100μg/ml的用量可抑制固体培养中小球藻的生长；而对G418表现出高度敏感性，30μg/ml的G418即可完全抑制固体培养中小球藻的生长，15μg/ml的G418即可完全抑制液体培养中小球藻的生长。

The effect of commonly used vegetation index NDVI was not ideal in monitoring leaf chlorophyll concentration in this study.

常用植被指数NDVI在本研究中对小麦叶片的叶绿素含量的监测效果并不理想。

A new study just published in the International Journal of Cancer examined the activity of chlorophyllin and found that, on a dose-by-dose basis , it was 10 times more potent at causing death of colon cancer cells than hydroxyurea, a chemotherapeutic drug commonly used in cancer treatment.

根据国际癌症杂志的一项对叶绿酸的活性研究，发现同等剂量下，它比常用的化疗药物羟基脲在杀死结肠癌细胞的作用要强10倍。

New research shows that chlorophyllin -- a water-soluble derivative of chlorophyll, the green pigment found in most plants -- may be 10 times more potent at killing colon cancer cells than hydroxyurea, a chemotherapeutic drug commonly used in cancer treatment.

新的研究表明叶绿酸，这种多数植物里都含有的叶绿素的水溶性衍生物，可能比常用的化疗药物羟基脲在导致结肠癌细胞死亡的作用上要强10倍。

But the paradox in the function of Social Choice always prevents the development of democracy.

投票作为人类最古老的群决策方法，也是社会选择理论最常用的决策手段之一。

According to corresponding physical parameters, the neutron pulses formed by the single-chop-disk and the double-chop-disk were simulated by internationally popular Mcstas software respectively,and the influence curves of physical parameters on the pulses from the chop-chop- disks were obtained.

采用国际上常用的Mcstas模拟计算软件，分别对单斩盘和异向双斩盘产生的中子束流脉冲的形成特性进行了模拟计算，获得了相关物理参数对斩盘产生中子束流脉冲的影响曲线，讨论了单斩盘与双斩盘脉冲形成的束流特性的差别与优缺点。

Chromo paper: A smooth, heavily coated paper, usually only coated on one side, often used for the printing of multi-colours such as labels, etc.

彩印纸：一种平滑，涂层特厚的纸。此种纸多数涂布一面，常用于多色彩印如标签等。

The V-sign itself is a challenge, for the famous Churchillian invention that used to mean Allied Victory is no longer valid.

Ciphering information with Cipher technology is the most common and effective method.

军事通信的安全保密是国防建设中的重要问题，如何确保重要信息的安全也就成为各方关注的一个重点，采用密码技术对信息加密是最常用、最有效的安全保护手段。

In engineering practice, the circle sliced method is popularly used in slope stability assessment.

滑坡是土坡重力侵蚀破坏的主要形式，在目前的工程实践中，土坡稳定性分析最常用的方法是圆弧条分法。

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.
