specific efficacy
解釋
固有功能-
Chemotaxis mediated by chemokine receptors, such as cxcr4, play a key role in lymphocyte homing and hematopoiesis as well as in breast cancer metastasis. we have previously demonstrated that ? - arrestin2 functions to attenuate cxcr4 - meidated g protein activation and to enhance cxcr4 internalization. here we further show that expression of ( - arrestin2 in both hela and hek293 cells significantly enhanced the chemotactic efficacy of stromal - cell derived factor 1 ( ( sdf - 1 ( ), the specific agonist of cxcr4
- arrestin2是趨化因子受體的一種重要的調節蛋白，本研究工作發現在hek - 293或hela細胞中升高- arrestin2的表達水平會顯著增強cxcr4介導的趨化作用，反之當- arrestin2的表達被它的反義核苷酸或rnai所抑制， cxcr4介導的趨化作用則被明顯抑制。 -
On the basis of collecting and processing many datum and materials. firstly. this paper analyzes main activities and cost constitutions of each stage of the life cycle of a fcs, and lay a foundation for later analysis and evaluation of system lcc. secondly, a basis method and usage range for estimating the system lcc are introduced. a multivariate linear regression model of pcs development cost and cost driven factor is built by use of the parametric method and supplies the base of cost estimation of newly - developed systems. thirdly, combine actual examples and make statistical analysis of lcc of a certain pcs developed by our institute, predict unhappened usage and service cost with grey prediction method, obtain proportion of each constitute to the lcc. forthly, according to actual conditions, use the fuzzy theory to overall evaluate efficacy of the fcs, fifthly, combimng our actual conditions, investigate specific measures of how to implement the life cycle cost management in our institute and put forward a new conception of developing web - based flight control system lcc management information system with pdm as the platform. at last, investigate important factors such as reliability and maintainability that may affect the life cycle cost of the fcs in detail, and put forward specific methods of lowering the life cycle cost of the fcs
論文在收集和整理大量資料的基礎上，首先深入分析了飛控系統壽命周期各階段的主要活動以及各階段的費用構成，為以後系統壽命周期費用的分析和評價奠定了基礎；其次，介紹了壽命周期費用估算的基本方法和使用范圍，並利用參數法建立了飛控系統研製費用與費用驅動因子的多元線性回歸模型，為新研系統的費用估算提供了依據；第三，結合實例對我所研製的某型飛控系統的壽命周期費用進行統計分析，運用灰色預測方法對未發生的使用及維修費用進行預測，得出了該系統的壽命周期費用以及各組成部分所佔比例；第四，根據實際情況，首次運用模糊理論對飛控系統的系統效能進行了綜合評價，構造了飛控系統系統效能模糊綜合評價模型；第五，結合我所實際，探討了如何在本單位實施加強壽命周期費用管理的具體措施，提出以pdm為平臺，開發基於web的飛控系統lcc管理信息系統的新構思；最後，對影響飛控系統壽命周期費用的重要因素如可靠性和維修性等進行了詳細地研究，提出了降低飛控系統壽命周期費用的具體方法。 -
