因子

Finally, on the basis of analysing the structure of environmental region of Chinas each province and municipality,and social economic structure,the relation Shop between the two was probedinto,and the leading direction of social economin a justment and control to improve environmental quality in different types of regions were determined.

从地域的角度出发，构建环境综合指数，并分析中国各省市区的环境地域结构；通过因子分析方法，选择与环境状况有关的社会经济因子综合成若干公共因子，建筑经济发展的主驱动力，并考察社会经济地域差异；最后，在分析中国各省市环境地域结构和社会经济结构的基础上，探讨了二者之间的关系，确定了不同地域类型改善环境质量的社会经济调控主导方向。

In this assessment, two groups of evaluation factors were used: one group is stipulated in "Environment quality standards for surface water (GB3838-2002)"; the other factors included main pollutants of Jinhe River, such as kjeldahl nitrogen, nitrite nitrogen, nitrate nitrogen and chlorophyll a, and the standards of some of them were given by the author on the basis of relative data.

在此评价中，采用了两组评价因子，一组是地表水环境质量标准(GB3838-2002)内的因子，一组除了标准内的水质因子，还包括了津河的主要污染物凯氏氮、亚硝酸盐氮、硝酸盐氮和叶绿素，这些污染物的标准是经过查阅资料自定的。

AIM: To investigate the effects of goat placenta immunoregulating factor on the expression of costimulatory molecules lineaged T cells in BALB/c mice. METHODS: Animal model for immunodeficiency made from BALB/c mice with whole-body irradiation by 5 Gy 60Coγ-ray was applied for research.

目的：分析羊胎盘免疫调节因子对BALB/c小鼠T淋巴细胞共刺激表面抗原分子表达及其细胞因子分泌的影响，探讨羊胎盘免疫调节因子免疫促进作用机理。

In this paper,the response factors of thermal conductivity detector of monochloromethane and dimethyl ether are estimated and calculated by using group cross section area method,molecular diameter method and homologue linear rule method.

热导校正因子的估算以及在工业氯甲烷生产中的应用李洪宽（山东省化工研究院色谱中心济南250014）关键词气相色谱法，一氯甲烷，热导检测器，校正因子1前言热导检测器定量校正因子的测定和计算是气相色谱热导定量的关键。

The importance of the role of these morphogenic substances, as well as their mechanism of action, is evident by the fact that they have been conserved throughout evolution, where different variants can be found to exist in species ranging from worms to fruit flies and up to higher species including humans.

这些形态因子及其作用机理的重要性是显而易见的，事实上，在进化过程中这些因子是非常保守的，不同的物种包括蠕虫，果蝇以及高级物种人类在内，都存在形态因子的不同形式。

TGF-β s are multifunctional cytokines with a broad range of biological activities. TGF-β s belong to a family of related proteins, which demonstrate various degrees of amino acid sequence homology; this protein family is called the TGF-β superfamily. Other members of this family include the bone morphogenetic proteins, inhibin, activin and Mullerian substance.

TGF-β类生长因子是一类具有广泛生物学活性和重要临床应用价值的细胞因子，包括多种蛋白因子，它们在氨基酸结构上具有不同程度的同源性，共同构成了TGF-β超家族，包括BMPs、活化素、抑制素和缪勒氏物质等。

In combination with the change of motor endplate and myodynamia, acupuncture can improve the function of wounded limbs.

针刺能明显提高周围神经损伤后雪旺细胞的功能状态，促使其分泌NGF、神经生长因子受体、碱性成纤维细胞生长因子，并能延长内源性神经营养因子的作用时间。

They are determination factors in skeletal muscle myogenesis. They consist of MyoD, myf5, myogenin and MRF4. They play an important role in embryonic muscle development. They can activate the expression of muscle specific gene. They express in a temporal and spatial pattern in muscle development.

成肌调节因子是一组转录因子，它们是胚胎时期骨骼肌发生的决定因子，该家族主要有4个成员：MyoD、Myf5、Myogenin和MRF4，它们在胚胎时期肌肉发生中起着重要的调控作用，能激活肌肉特异性基因的表达。
