因子

PCA is to perform the variable transformation, whereas factor analysis needs to form a factor model.

主元分析只是进行一定的变量变换，而因子分析则需构成因子模型。

Objective: To explore the therapeutic effect of the Yishenhuoxue capsule on basic fibroblast growth factor and transformation growth factorβ1 (TGF-β1) of hyperhomocysteinemia rats.

目的：观察益肾活血胶囊对同型半胱氨酸血症大鼠碱性成纤维细胞生长因子，转化生长因子β1(TGF-β1)的影响。

Objective To detect the expression of basic fibroblast growth factor and E26 transformation specific 1(Ets 1) in primary ovarian carcinoma to provide new evidence for understanding the biological behavior of primary ovarian carcinoma.

目的检测碱性成纤维细胞生长因子(basicfibroblastgrowthfactor ，bFGF)和E2 6转录因子(E2 6transformation specific 1 ，Ets 1 )在原发性卵巢癌中的表达，为评估卵巢癌的生物学行为提供新的依据。

In general, cytokines are induced transiently upon cell activation.

细胞因子是由机体细胞合成并分泌的小分子多肽类因子，它们参与多种细胞的增殖、分化，在免疫和炎症反应中发挥重要作用。

So there must be some non-specific and transiently expressed factors involved in this process.

这提示TCS免疫之后可引起局部淋巴结细胞短暂地产生出一些非抗原特异性的因子，这些因子可进一步促进在此微环境中的无关抗原的IgE抗体应答。

Aims: To investigate the expression and significance of epidermal growth factor receptor, cyclooxygenase-2 and trefoil factor 1 in the carcinogenesis of gastric mucosa.

目的：探讨表皮生长因子受体、环氧合酶-2和三叶因子1在胃黏膜癌变过程中的变化规律及其意义。

We introduce some concepts, such as yon Neumann algebras, factor von Neumann algebras, nest algebras and so on, and give some well-known theorems that we will use in this paper. In Chapter 2, we put our attention on linear maps that preserving zero Jordan triple product on nest subalgebrasof factor yon Neumann algebras.

第二章首先对因子von Neumann代数中套子代数上保Jordan三重零积的线性映射进行了研究，证明了从因子von Neumann代数中套子代数到任一有单位元的Banach代数的保Jordan三重零积的单位线性双射是Jordan同构。

In the evaluation, we find that in order to achieve a high and appropriate correct classification rate, the cutoff should be selected by trading off tyeⅠerror rate and the typeⅡerror and efforts should be made to reduce the potential cost of two types of errors to the decision-maker.

结果显示，在jackknife method方法下包含了多因素因子的模型对经营困境的分类识别能力比单独使用财务变量因子的模型有较大增强，说明非财务变量包含了与经营困境有关的重要信息。

Density, size and maturity of buckwheat seeds, temperature, radiation, ultra-violet light, GA, 6-BA , microelement were the dominant factors; Main study on sprout status, sprout ration, vigor index, plant height, yield, vitamin C, total flavonoids content and variation of correlated enzyme, in order to find out the correlated parameter that all factors affected the buckwheat, then we could guide the production.

中文摘要：本试验以种子的千粒重、大小和成熟度，温度、光照、微量元素、赤霉素、6-BA、紫外光等为主要影响因子，对苦荞种子的发芽势、发芽率、活力指数，苦荞芽菜的株高、产量、维生素C和总黄酮含量以及相关酶活性的变化进行了研究，期望找出各因子对苦荞芽菜生长和生理影响的相关参数，以指导生产。

The colloidal material concentration is calculated by using integral sample concentrations of ultrafiltrate and retention with concentrate factors

实际分析样品时，应选择合适的浓缩因子，固定的膜压及流速对样品进行分离，胶体物质浓度应用超滤结束后超滤液和浓缩液中的物质浓度结合浓缩因子进行计算。

The basic concept of FOP can be summarized as to further optimize effective prescription according to the standard of curative effects and with the aid of modern science and technology and theories of traditional Chinese medicine.

其基本内涵可概括为：以确有疗效的中药复方为研究对象，以现代科学技术和传统中医药理论为技术支持，以该复方所治病证的药效响应为评价标准，以优化重组疗效更优的新复方为研究目的。

Ever since our world has been a world, native forests have been indiscriminately exploited by man.

自从我们的世界一直是世界原生森林被任意剥削人。
