Purpuraristatus, the growth, fertility, chromosome configuration, EST isozyme etc. were analyzed in this paper. The results showed that the growth potentiality of (E. sibiricus×E. purpuraristatus) F2 and (E. purpuraristatus×E. sibiricus) F1 were much stronger than their parents, the plant height of the former was 143.2 cm. The whole plant was reseda, the latter was 129.7 cm. The spike nodding of two hybrids were in the middle of their parents, the anther was yellow; the pollen fertility was 0.02%~0.03%, seed set was 0; the average chromosome configuration of former pollen mother cell at PMC M Ⅰ was 6.90Ⅰ+14. 02Ⅱ, the latter was 7.82Ⅰ+13.59 Ⅱ, and lagging chromosome and bridge fragment were observed at meiosis anaphase Ⅰ the EST of the two hybrids F1 and their parents at tillering stage was some certain different in locus, number and intensity.

结果表明，正交F1和反交F1植株的生长势均很强，正交F1株高143.2 cm、全株浅绿色，反交F1株高129.7 cm、全株灰绿色；正、反交F1的穗型均呈双亲中间型，花药呈黄色，花粉可育率0.02%~0.03%，结实率为0，说明杂种高度不育；正交F1的花粉母细胞减数分裂中期Ⅰ平均染色体构型为6.90Ⅰ+14.02Ⅱ，反交F1为7.82Ⅰ+13.59Ⅱ，减数分裂后期丁有落后染色体和染色体桥等不规则现象；亲本及其正、反交杂种F1分某期幼叶的EST同工酶酶带的位点、数目和强弱均存在一定差异，可作为亲本及杂种在蛋白质水平识别的重要依据。

Mammalian Spermatogenesis is a unique cell differentiation process and can bedivided into three stages: mitosis, meiosis, and spermiogenesis.

哺乳动物的精子发生是一个复杂的细胞分化过程，可分为有丝分裂期、减数分裂期和精子形成期三个阶段。

Results: The differentiated neuron appeared different patterns of amitotic figures such as transverse sever, longitudinal split, etc. The proliferating neurons divided in an asymmetric way morphologically and chemically. The differentiated neuron appeared an obvious movement of cell migration and neurite extension.

结果：培养分化的神经细胞呈现横裂、纵裂等不同方式的无丝分裂像；分裂中的神经细胞可呈现形态及化学不对称性；分化的神经细胞有明显的细胞迁徙运动和突起延伸。

Certain structure such as cleft/pseudo-cleft sentence, existential sentences can focalize certain sentence elements in both English and Chinese, the difference lies in that the focalization of predication can be achieved through nominalization, which is not exist in Chinese.

第二，句法方面，可分为特殊结构和成分移位两种手段。英汉语中都存在分裂/准分裂句，存在/隐现句等特殊聚焦结构，其功能都是将需要凸显的句子成分纳入一个特定位置而实现焦点化。

Myoblastic cells from patients with PM had a weaker ability of developing into the myotubules, thus they were unable to perform effective regeneration, which resulted in a progressive necrosis. The exogenous bFGF could promote the division and proliferation of the muscle cells in vitro . These results shield a light on bFGF's potential role in preventing and treating PM.

PM患者受损腓肠肌在体外有再生能力，但融合成肌管能力极弱，存在再生障碍，不能对变性、坏死的肌纤维形成有效再生，故呈进行性肌纤维耗竭；外源性bFGF可促进PM患者体外培养骨骼肌细胞增殖分裂，并可促进肌管成熟，对进展性肌病应具有防治作用。

Thus it is obvious that the weak homology existedamong genomes A, B, D and 〓. However, the rare unreduced gemetes and near-unreduced ones with the loss of several chromosomes could be produced by the highlyunequtional division of univalents at the first meisis and the normal second division,which gave the F1 hybrid the partial fertility.

但通过第一次减数分裂时单价体的极不对称的分离及正常的第二次分裂，可形成少量未减数配子和丢失了少数几条染色体的近未减数配子，使杂种〓表现部分可育性。

This method can be applied to any thermodynamic model, including activity coefficient model and EOS model, and this work extends phase analysis from liquid-liquid phase splitting to liquid-liquid-vapor phase splitting.

经多个实例的测试表明，LCPSO适用面广，既可用于超额自由能、状态方程等各类热力学模型，又能克服混合模型一阶不连续的困难，应用范围从液液相分裂拓展到汽液液相分裂。

Then PLGA Micro spheres can promotes the proliferation of osteoblast in a long perlod because of the controlled release of bFGF from microspheres. The PELA microspheres satisfied the proprty reguirement of controlled release, but the biological activity of the released bFGF is partially destroyed.

2体外细胞试验中，游离bFGF对成骨细胞具有促分裂增殖的作用，但效应期很短；而PLGA微球通过持续释放活性bFGF，可在较长时期内促进成骨细胞的分裂增殖；PELA微球虽然达到了缓释的性能要求，但释放出的bFGF的生物活性受到了破坏。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
