在生长发育中

The present work was de-signed to study systematically the changes of anther and pollen during themannitol pretreatment period on physiology and biochemistry;and then the ef-fects of mannnitol pretreatment on androgenesis and anther culture were stu-died.The donor plants used in this experiment grow in the field.

所以本文从以上几个问题出发，以大田生长的植株作为供试材料，首次系统地研究了甘露醇预处理过程中大麦花药花粉在生理生化方面所发生的变化；以及甘露醇预处理后对大麦雄核发育和培养效果的影响。

DRUSE minerals in the rock is fractured by the growth of many minerals or empty single cluster aggregates formed vigilance . They shared one end fixed to the base rock , the other side of freedom and good crystal growth firms .

矿物晶簇是指由生长在岩石的裂隙或空洞中的许多矿物单晶体所组成的簇状集合体，它们一端固定于共同的基地岩石上，另一端自由发育而具有良好的晶行。

It is known from in vitro fertilisation research that high levels of glucose can enhance the growth and development of male embryos but inhibit female ones.

高水平的葡萄糖能提高男性胚胎的生长和发育但是抑制了女性胚胎，这在体外受精的研究中广为人知。

Some of these genes have been successfully incorporated into plants . The insect-resistant transgenic plants inhibit development and decrease fecundity of homopteran insects , demonstrating practical potential of these insect-resistant genes in the control of this group of pests .

其中一些基因已被成功地转入植物体内，并且获得的转基因抗虫植物对同翅目害虫的生长，发育，繁殖能力等方面都具有一定的抑制作用，表现出这些抗虫基因在防治这类害虫中的应用潜力。

Therefore, Lef-1 palys an fundamental role in morphogenesis and cylce of the hair follicle.

因此，Lef-1因子在毛囊的发育和生长的过程中起到重要的调节作用。

The result s showed that the outgrowth of neurites as well as neuroglia cells from SCG were significantly increased when SCG were incubated with non-lymphoid conditioned medium compared with that of control medium.

结果显示，与对照培养液相比，条件培养液能够显著地促进体外培养中颈上节交感神经生长锥的发育，且这一作用在不同程度上可被抗NGF和NT-3抗体特异性阻断。

All results above indicated that:The expression of ERβand p-ERβin mouse ovary at oestrous cycle and in early gestational period changed regularly, it showed that ERβand p-ERβhad important effects to ovaries development, ovarian follicles groth, oocyte maturation and form corepus luteum in female mouse ovary during oestrous cycle and in early gestational period.

以上结果表明：ERβ及其磷酸化形式——p-ERβ在小鼠发情周期以及妊娠早期卵巢中表达有规律性的变化，揭示ERβ与p-ERβ在雌性小鼠发情周期及妊娠早期，对卵巢发育、卵泡生长、卵母细胞成熟和黄体形成有重要的作用。

Preinduction was performed using basic fibroblast growth factor, which could promote the differentiation from BMSCs into nerve precursor cells or neurons. The expression of neuroprotein molecule was coincided with the development of neural cells.

在添加化学诱导剂之前先使用成纤维生长因子进行预诱导，能促进骨髓间充质干细胞向神经前体细胞和神经元转化，且在诱导分化过程中神经蛋白分子的表达顺序与神经细胞发育过程一致。

It is suggested that the sodium selenite might be effective for inducing apoptosis in cultured cortical neurons, and the relavant changes in expression of several genes might underly the mechanisms which initiate and maintain the apoptptic processes.

硒是人和动物体必需的微量元素，已检出25余种含硒蛋白及亚单位，其中有些在脑组织中分布广泛，并且在调节神经元和胶质细胞的生长、发育、和功能维持等方面具有重要的作用。

The distribution of the growth-associated protein (GAP-43) which is close related to the axon regeneration was examined by immunocytochemical method in the adult rat brain and the rat parietal lobus injuried into which the fetal cerebral suspension was lransplanted.

在发现流式细胞计可用于神经科学的研究后，用FCM研究了大鼠脑发育过程中细胞周期的变化和胚胎大脑细胞移植到成年大鼠顶叶后对宿主顶叶脑细胞分裂的影响；由于生长相关蛋白(GAP-43)与轴突再生密切相关，用免疫细胞化学法研究了GAP-43在成年大鼠脑内的分布及顶叶损伤植入胚胎大脑细胞后GAP-43的变化。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
