本发明利用连城白鸭胚胎作为材料，进行初代培养、传代培养及细胞冻存等研究。最终获得高活率、高纯度的连城白鸭胚成纤维细胞系，其保藏编号为CGMCC No.1877属于细胞生物学领域。本发明培养的成纤维细胞无上皮细胞等，细胞纯度高；冻存后细胞质量稳定，活率可达到并维持在93.5％～96.8％之间，传代生长稳定，适合大规模培养。

Female inflorescence pendulous or erect, with numerous overlapping bracts; each bract subtending a small dichasium with 2 or 3 flowers; calyx with 1-6 scalelike lobes, or obsolete; petals absent; ovary inferior, 2-loculed; styles 2, free; ovules 2, or 1 by abortion, pendulous from near apex of each locule.

雌花序下垂或直立，具多数重叠操作苞片；每苞片对着一小的二歧聚伞花序具2或3花；花萼具1-6鳞片状的裂片，或废退；花瓣无；子房下位，2室；花柱2，离生；胚珠2，或以败育，从近先端那里下垂具有每一个子房室。

Using the theory of normal forms of diffeomorphism and according to nonlinear participation factors, a more accurate method to decide the location to implement load control or the place to allocate static var compensator is proposed.

应用微分同胚正规形理论，以非线性参与因子为依据，提出了确定实施负荷控制的地点及静止无功补偿(static var compensator，SVC)安装地点的更准确方法。

A class of affine nonlinear system of single input-single output is investigated. Firstly, the nonlinear system is transformed into an equivalent linear system through a diffeomorphism transformation. The networked control problems for the delays are constant, stochastic and shorter than a sampling period, and long and stochastic are investigated respectively.

针对一类单输入-单输出仿射非线性系统，首先通过微分同胚变换实现了仿射非线性系统的无反馈精确线性化；然后基于精确化线性模型，分别讨论网络延时为常时滞，随机时滞小于一个采样周期和随机长时滞情况的控制问题。

子房上位。心皮2，合生，柄，1，具毛的无毛或，侧膜胎座；胚珠2到多数，倒生；花柱1，有毛；柱头头状，浅裂。

Awn 5–6 mm, arising from middle of lemma; glumes smooth or scabrid only on keel.

花瓣1-1.5毫米；每果种子和败育的胚珠24-38；花柱无； 8 D。 rosea 玫红野青茅

Female flowers: perianth membranous, veinless, enlarging with ovary in fruit and enclosing utricle, apex 5-lobed or entire; ovary subovoid, slightly compressed; ovule stalked; style obscure; stigmas 2 or 3, subulate.

雌花： 花被膜，无脉，在果期子房扩大和包围胞果，顶5浅裂或全缘；近卵形的子房，稍压扁；胚珠柄；花柱不明显柱头2或3，钻形。

In one study, researchers listed foods typical of five diets: vegetarian (broccoli quiche, brown rice, avocado and bean sprout sandwich), gourmet (oysters, caviar, French roast coffee), health food (protein shake, wheat germ, yogurt), fast food (KENTUCKY Fried Chicken, Big Mac, pizza), and synthetic food (Carnation Instant Breakfast, Cheez Whiz).

在一项研究中，研究人员列出食品典型的五个饮食：素食（青花菜基切，糙米，鳄梨和豆芽夹心），美食（牡蛎，鱼子酱，法国烤咖啡），保健食品（蛋白质动摇，小麦胚芽，酸奶），快餐（肯德基炸鸡，巨无霸，披萨），并合成食品（香石竹瞬间早餐， cheez奇才）。

Blab/c nude mice of 6-10 weeks old were also used. METHODS: Fresh lower mandible of 12 weeks abortion human embryo was separated; human molar tooth germ was isolated.

无菌条件下分离新鲜的12周流产人胚胎下颌，分离磨牙牙胚。

Nevski in vitro and selected several favorable media.Germ-free plants were produced with germination on MS medium. Callus was induced with B5+1.5 mg.L-1 2,4-D+0.5 mg.L-1 NAA,with leaf sheath and hypocotyls as explants.

Nevski种子消毒并在MS培养基上萌发获得无菌苗，以幼苗的叶鞘和胚轴为外植体诱导愈伤组织，经继代后进一步诱导不定芽及生根。

I will endeavour to find you some assistance.

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
