My name is Saran and I ' m14 years old .

我的名字是Sara并且我14岁。

In order to obtain the gene of full length , the cDNA Library of M14 bud was constructed through highly efficient and simplified method .

为了得到全长基因，采用cDNA文库快速构建法制备了M14花蕾cDNA文库。

Cyto-embryological Study of the Apomixis of the Monosomic Addition Line M14 in Sugarbeet

Research on Specific Expressed Genes in Florescence of the Apomictic Line M14 of Beta corolliflora in Sugar Beet

甜菜无融合生殖品系M14花期特异表达基因的研究

The observation of Microsporogenesis and the development of male gametophytes in the monosomic addition lines of apomictic beet M14

甜菜无融合生殖单体附加系M14的小孢子发生与雄配子体发育的观察

Using the Dual-phase steel wire rod can produce 8 . 8 grade M10 , M14 hexagon head tap bolts and M8 tapped studs .

用该双相钢盘条可生产8.8级M10，M14六角头螺栓和M8双头螺柱。

As an example , the maximum wall temperature of 203 mm howitzer using M14 slotted stick propellant is 1284 K , the heat wear in single shot is 17 9 μ m.

该文还以某榴弹炮的M14开槽管状装药为例，计算得其膛壁最高温度为1284K，单发磨损为17.9μm。

And according the sequence of FIE gene , designs a pair of primer , uses RT-PCR and colones the specific fragment of Beta vulgaris M14 FIE gene .

同时根据已发表的不同植物FIE基因序列的高度同源区，设计一对引物，以甜菜M14花蕾总RNA为模板进行RT&PCR扩增甜菜M14FIE特异片段。

The influence of cultural conditions , such as nitrogen source , C / N ratio , pH , age and volume of inoculum on cell growth and lipid formation of Mortierella sp . M14 strain was studied .

对培养条件，如氮源种类、C/N比率、pH、种子种龄与接种量对被孢霉（Mortierellasp.）M14菌株的细胞生长和油脂形成的影响作了研究。

Inorganic nitrogen source contributed to produce unsaturated fatty acid and organic nitrogen source contributed the cell growth of M14 . Low C / N ratio facilitate the enhancement of biomass , higher C / N ratio was able to promote the synthesis of lipid in mycelia .

无机氮源有利于不饱和脂肪酸的产生，有机氮源有利于细胞的增殖。低C/N比率有利于菌丝体产量的提高，提高C/N比率则能促进菌体细胞内的油脂合成。

We choose Beta vulgaris line M14 to be our experiment object , not only because Beta vulgaris are widely planted in China , what is more important , people obtained some precious subspecies in the long-term cultivating process , and accumulated plenty of genetic informations .

我们选择甜菜作为实验对象不仅仅因为甜菜在我国广泛栽培。具有可观的经济价值，更重要的是人们在甜菜的长期培育过程中获得了若干宝贵的亚种，积累了人量遗传信息。

The time of infection of pigs by JE and M14 viruses was identical . No evidence was provided that JE virus was inhibited by M14 virus in nature and it seemed that the lower epidemicity of JE had nothing to do with M14 virus .

猪感染M14病毒与感染乙脑病毒的时间基本相同，表明这两种病毒在自然界传播中不存在明显的互相干扰关系，乙脑低流行年的出现并未受到M14病毒的影响。
