According to the number and behavior of B genomechromosomes, all hybrid plants were classified into three types. All somatic cells of TypesⅠplants contained 16 B genome chromosomes which formed 8Ⅱat diakinesis and shown8:8 segregation at anaphase; TypesⅡcontained 14 B genome chromosomes whichformed 6Ⅱ+2Ⅰat diakinesis and showed 6:8 or 7:7 segregation at anaphase. TypesⅢcontained above two chromosomes number and behavior.

On the basis of the previous work, we make further study on the mechanism of the denucleation process, especially on the role of different cytoskeletal elements in the denucleation process. To clone and sequence a gene related to terminal differentiation of erythroblast, and construction of two cDNA libraries of erythroblast differentiation. The results of our study are as follows

本文在我室前期工作的基础上，对红系细胞终末分化中的排核机理作了进一步的探讨，克隆、测序并表达了一个与红系细胞终末分化相关的基因，另外，还成功地构建了小鼠终末分化和差减cDNA两个红系分化cDNA文库，为本室以后的基因克隆工作打下了基础。

Of our famed rods and cones, the two classes of light-sensing cells with which the retina at the back of each eye is supplied, the rods do the basics of vision, of light versus shadow, tracking every passing photon and allowing us to see by even a star's feeble flicker, though only in gunmetal shades of black, white and grim.

在我们眼球后面的视网膜上有锥状和柱状两类感受光亮的细胞。柱细胞承担视觉的基本操作，分辨明暗，跟踪光子，使我们透过那怕只是由黑白蓝调出的铁灰色，也能看见遥遥星空的闪烁。

Results:Normal rats as the donator of serum, using methanolic extract of CWC, 10 times equivalent dose for adults every day, intragastric administration twice a day of 8-hour interval, keeping on 3 days, hemospasia after 2 hours of the last administration was the better preparative method of the serum containing drug.

建立CCl4诱导的原代培养大鼠肝细胞损伤模型，大鼠为含药血清供体，以含药血清对损伤肝细胞增殖及丙氨酸氨基转移酶泄漏的影响两个指标，结合含药血清中五味子乙素的含量测定，分别采用单因素考察、多因素的正交试验，优选含药血清的制备方法，并确定体系中血清添加量。

Rather than one cell group being the master control of the clock as scientists had assumed, the two cell groups take turns acting as master and slave.

这两种细胞轮流扮演控制与被控制的角色，而不是像先前科学家推测的一种细胞占据控制生物钟的角色。

So we selected thevinblastine optimum parameters were 0.1μg/ml and 8 hour cultured duration.The fourth, there were significantly differences percent between 10 hourgroups and other three groups in 0.1μg/ml groups; and there were no significantlydifferences between 8 hour groups and 10 hour groups, but they had significantlydifferences among other two groups in 0.3μg/ml groups; and there weresignificantly differences between 10 hour groups and other three hour groups in0.5μg/ml groups; and there were significantly differences between 10 hour groupsand other three groups in 0.7μg/ml groups on the metaphases (P＜0.05), in theexperiment of the effect on the mouse 8- cell embryo stage single blastomere ofvinblastine with different concentrations and duration, by x~2 statistical analysis.

根据实验的实际情况，适宜制备小鼠4-细胞期胚胎单卵裂球染色体标本的长春花碱的处理浓度和时间是0.1μg／ml和8小时。4、在确定长春花碱不同处理浓度和时间对小鼠8-细胞期胚胎单卵裂球中期分裂相数影响的实验中，经统计分析，阻断培养0.1μg／ml浓度组中10小时组与其他三组差异显著；阻断培养0.3μg／ml浓度组中8小时组和10小时组间差异不显著，但与其他两组差异显著；阻断培养0.5μg／ml浓度组中10小时组与其他三组差异显著；阻断培养0.7μg／ml浓度组中10小时组与其他三组差异显著(P＜0.05)。

Sowe selected the vinblastine optimum parameters were 0.1μg/ml and 8 hourcultured duration.The fifth, there were significantly differences between 0.45% sodium chloride groups and other two groups (0.5% sodium citrate groups and 0.35%potassium chloride groups) on the metaphases (P＜0.05), in the experiment of theeffect on the mouse 4-and 8-cell embryo stage single blastomere of differenthypotonic fluids, by x~2 statistical analysis.

根据实验的实际情况，适宜制备小鼠8-细胞期胚胎单卵裂球染色体标本的长春花碱的处理浓度和时间是0.1μg／ml和10小时。5、在确定不同种类低渗液处理对小鼠4、8-细胞期胚胎单卵裂球中期分裂相数影响的实验中，经统计分析，0.45％氯化钠低渗液组与其他两组(0.5％柠檬酸钠和0.35％氯化钾)差异显著(P＜0.05)。

Udensis' genetic variation, its historical causes and dispersal, and references for the explanation of China's geological changes and post-Pleistocene geographical dispersal of plants.

由于七筋菇植物不同细胞型共存，两种细胞型的分布区相邻或重叠，为我们探讨七筋菇种群的遗传结构和遗传分化，多倍体的起源、扩散和演化，及其迁移路线提供了理想的天然研究场所。

In both cases, when they grew the cells in the presence of a chemical that infiltrates newly synthesised DNA, they could see that the unlabelled template strands of DNA went into one daughter cell and the new strands went to the other.

他们在培养基中添加能渗入新合成DNA的化学试剂，结果，两种情况下都观察到未标记的模板DNA链进入了一个子细胞，而新合成的DNA链进入了另一个子细胞。

The cell outline was collected with two-step expansion model of modified Snake,at the same time;greedy algorithm was applied to reduce the operative time of procedure.Upon the basis that the segmentation of wood cell intracavity and edge was finished,wood cell wall was identified.

利用改进的Snake两步膨胀模型对细胞轮廓进行提取，同时应用贪婪优化算法，减少程序运行时间，在完成对木材细胞内腔和边缘分割的基础上，完成对木材细胞壁的识别。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
