Studies on mouse nuclear transfer with compacted morula blastomeres as donors In this study, C57BL/6 mouse morulae blastomeres and Kunming white mouse MⅡoocytes were used as donors and recipients, respectively, to investigate the effects of different sucrose concentration on the manipulation time of nuclear transfer, and the in vitro development of reconstructed embryos.

Basal leaves often withering early; petiole 1.2--1.5 cm. Stem leaves usually in whorls of 4, sessile or petiole to 2.2 cm, densely villous; leaf blade long ovate or ovate-oblong, 2--5 X 1.1--2.2 cm, abaxially whitish scurfy, adaxially sparsely pubescent, pinnatifid; segments triangular-ovate to long ovate, dentate.

基生叶通常早枯萎；叶柄1.2-1.5 厘米茎生叶通常在4，无梗或叶柄在2.2厘米，密被长柔毛轮生方面；叶片长卵形或卵形长圆形，2-5 X 1.1-2.2厘米，背面带白色具鳞屑，正面疏生短柔毛，羽状半裂；裂片三角状卵形的到长卵形，具牙齿。

Different strains have different reaction to the delay of oviducts in body after animal death. After 10min delay C57BL/6 mouse oocytes have death rate of 56.5%,significantely higher than Kunming mouse (47.6%);Spontaneous activation rates were respectively 13.3% and 46.0%, C57BL/6 were obviously lower than Kunming mouse.4. The oviducts were obtained after being delayed 5min 24h after the mice were injected with hCG. The oocytes were cultured in CZB. About 81.1% occurred spontaneous activation, evidently lower than parthenogenetic rate (96.4%) with SrCl_2. Spontaneous activable oocytes had high cleavage rate(93.2%) and 4-cell rate(87.3%). However, spontaneous activable oocytes had blastula development rate(18.7%) as low as parthenogenetic oocytes by SrCl_2(22.9%).

不同品系小鼠卵母细胞对输卵管在体内滞留产生的反应不同，滞留10min C57BL/6系小鼠卵母细胞死亡率为56.5%，显著高于昆明鼠(47.6%)；自发激活率分别为13.3%和46.0%，C57BL/6系小鼠显著低于昆明鼠。4.hCG后24h体内滞留5min卵母细胞在CZB中培养自发激活率为81.1%，显著低于SrCl_2孤雌激活率(96.4%)；自发激活的卵母细胞有较高的卵裂率(93.2%)和4-cell比率(87.3%)，但囊胚率(18.7%)较低，同卵龄的卵母细胞经SrCl_2孤雌激活囊胚发育率为22.9%，差异不显著。

The results showed that : 1 During nonbreeding season, the giant panda′s ovary was still rich with large and small follicular oocytes, and the large follicular oocytes could be matured in vitro; 2 The mean diameter of the oocytes was (141±6.7)μm and lots of cortical granules contained in the cytoplasm of oo...

结果表明∶（1）在非繁殖季节，大熊猫卵巢中小腔及大腔卵泡卵母细胞仍较丰富，其大腔卵泡卵母细胞可在体外培养成熟；（2）大熊猫的卵母细胞平均直径为（141±6.7）μm ，其胞质富含卵黄颗粒；（3）自配 PandaI I号获能液（含丙酮酸钠、肾上腺素等）可使大熊猫精子有效获能；（4）大熊猫卵母细胞体外受精后，经培养可观察到第2 极体，有的受精卵开始发生卵裂。

Leaves opposite or distal ones in whorls of 3 or 4, sessile or petiole to 5 mm, villous; leaf blade long ovate to ovate-oblong, 2--5 X 0.7--1.5 cm, pubescent on both surfaces, pinnatipartite to pinnatisect; segments 6--10 pairs, linear to linear-oblong, incised-dentate.

叶对生或上部的3轮生或4，对5毫米，具长柔毛的无梗或叶柄；叶片长卵形到卵状长圆形，2-5 X 0.7-1.5厘米，两面被短柔毛，对羽状全裂的羽状深裂；裂片6-10 对，线形的到线形长圆形，锐裂具牙齿。

4H was the best time of bovine oocyte activationin the 6-DAMP, and the cleavage rates and blastula rates could reach 85.1% and 26.8%. 4. IVF-100 was used in vitro fertilization, because IVF-100 was not needed to prepare usually,store conveniently, and gain a higher cleavage rates. After the oocytes have matured for 20h, theywere digested by permease and treated with suctionpipe.

由于IVF-100无需经常配制、保存方便且可以获得较高的卵裂率，所以本实验采用IVF-100为受精液，卵母细胞成熟20小时后采用透酶+口吸管消化的方法处理，获得了较好的受精效果，卵裂率可达(76.8％)。

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.

交际能力和语法的关系应该是目标与途径的关系。
