To some degree, this study revealed the relationship between ossein and bone miner and the important preventive and therapeutic effects of ossein on OP. It provides theoretical and experimental basis for the research and development of effective prescriptions to cure OP. Limited by the actual experimental situation, we only did some study on the synthesis and content of type Ⅰ collagen. Further study on the changes of decomposition and structure of type Ⅰ collagen are needed to be done.

本课题的研究，在一定程度上揭示了骨胶原纤维和矿物质之间互根互用的辨证关系，及Ⅰ型胶原在骨质疏松症的发病和治疗中所起的重要作用，并为开发研制治疗本病的有效中药复方提供了理论和实验依据，但由于条件所限，本研究仅就Ⅰ型胶原的合成及其含量变化做了初步观察，而本病中骨胶原纤维的分解代谢及其结构的改变，尚待进一步探讨。

However, a growing number of studies suggest that excessive extracellular glutamate and resultant overstimulation of its receptors cause excitotoxic roles and lead to neuronal damage in several pathological conditions such as cerebral ischemia. Normally, the excitatory postsynaptic roles of glutamate are terminated by the activities of high-affinity sodium dependent glutamate transporters that locate on neuroglial cells and neurons near the synaptic cleft, which are thought to play important roles in inactivating released glutamate and keep it below toxic levels in the extracellular space.

在生理状态下，突触间隙中谷氨酸的清除取决于邻近神经胶质细胞及神经元上高亲和力、钠依赖性谷氨酸载体的活动，通过该载体的再摄取机制保持细胞外谷氨酸浓度于正常范围，这在预防谷氨酸的神经毒中起着重要的作用。

Considerating over-all performance of mag nets, it was concluded that the optimal amount of doped-Ga was 0.5wt%. The other was that the grains size distribution of grains was narrow and grain distributed homogeneously as to microstructure of magnets when the amount of doped-Ga was 1 .Owt%;(3 ) In the magnets, there existed not only Nd2Fei4-xGaxB, but also GaNd concerning the Ga-elment form. The GaNd increased the amount of liquid and had favorable function during sintering, so it made for the increase of magnets density and the form of the second phase is good for improving coercivity.

综合考虑磁体的性能，最终得出添加0.5wt％为最佳的Ga添加量；(2)对于Nd_(15)Fe_(78)B_7+Ga系永磁体，当Ga的添加量为1.0wt％时，得到颗粒粒度分布范围窄，颗粒分布较均匀的显微结构；(3)元素Ga在磁体中不但以Nd_2Fe_(14-x)Ga_xB形式存在，而且以GaNd的形式存在，在烧结的过程中，增加了液相的数量，起助烧结的作用，有利于磁体密度的提高，形成第二相有利于矫顽力的提高。

A hypothetical particle of heredity postulated to be the mediating factor in the production of new cells in the theory of pangenesis.

胚芽，芽球在泛生论学说中，指遗传中的一种假定粒子，被假定认为在新细胞的产生中起媒介作用

In this paper dimension-chain is used to calculate the last effective dimension formed under the influence of tolerances and other distortions. Feature modeling is applied to construct the three-dimension mode of the parts in solidworks. Based on the parametric design function, simulation of assembling result is realized by making use of VB to develop Solidworks. The accomplish of variable parametric design system in tolerance designing is realiazed.

运用尺寸链技术计算出零件在公差及其他变形影响下的最终作用尺寸，利用solidworks中特征建模方法建立起装配体的三维模型，并根据该软件的参数化设计功能，利用VB对其进行二次开发，模拟了装配结果，实现了变参数设计方法在公差设计评价技术上的应用。

In corollary with the role of habitat patchiness in maintaining coexistence between competing species (see topic I1), environmental heterogeneity is likely to be of critical importance in allowing predators and prey to coexist.

由于生境斑块在维持竞争种间共存中所起的作用(见I1)推论，环境异质性很可能在允许捕食与猎物共存中具有关键的重要意义。

Margaret is the central as well as a multi-functional character in the novel and her special quality can be viewed in three aspects: in the story she is drawn away from the supposed female realm, into the dialogues with men and social activities; she is performing the abandoned paternalist role in her family, becoming "parent to the parent"; she is established by the author as a "rescuing heroine" and thus her final union with Thorton represents a new "unity of purpose" between the upper classes.The thesis tries to examine Margaret the heroine through a close look at the multiple role she plays in the narrative from the above three perspectives.

本篇论文试图从三个方面分析玛格丽特的人物性格塑造：借助女主人公在作品中频繁的"角色越位"，作者把玛格丽特塑造成"新女性家长"式的人物；同时，玛格丽特又是充满同情心的中介者，在厂主与工人两个对立阶级之间起着"传声筒"的作用，文本中各种不同的话语声音实际是对当时"英国现状论争"的体现；作品中的主要人物，尤其男女主人公，都带着鲜明的文化印记，是各自文化的产物，因此，玛格丽特与桑顿的婚姻被赋予了"社会解决方案"的象征意义。

This findings are the first to provide in vivo evidences for IGFBP-3 playing an important role in regulating development and growth of pharyngeal cartilage and otic vesicle, differentiations of optic and motor neuron, as well as its involving in the development of eye, pineal gland and pectoral fin bud in zebrafish.

这些新的发现，首次提供在体证据证明 IGFBP-3 在调节斑马鱼咽弓、内耳的生长发育、视神经和运动神经的分化过程中起着重要作用，并参与调节眼睛、松果腺、胸鳍的发育过程。

KAP6-1.5 and KAP8-2 were also expressed in internal root sheath of primary hair follicle discontinuitily. It demonstrated that KAP6、7、8 were important structure proteins of wool and cashmere cortex,and cells of cortex were keratinizated by KAP6、7、8.KAP6、7、8 participated in the synthesis of wool and cashmere directly, affected the physico-chemical property of pelage.

结果表明KAP6、7、8 mRNA在初级毛囊和次级毛囊的皮质层有强烈的表达信号，KAP6-1.5和KAP8-2mRNA在初级毛囊的内根鞘有微弱不连续的表达信号，说明KAP6、7、8是绒山羊毛和绒皮质蛋白的组成成分，是皮质层中起角质化作用的重要蛋白质，直接参与了绒毛和粗毛的合成，对毛发的理化性质有重要作用。
