differentiation phase 解釋
分化期
  • differentiation : n. 1. 差別，區別；區分，劃分。2. 【生物學】分化，變異。3. 【地質學；地理學】（從共同的巖漿產生出不同的巖石的）分異作用。4. 【數學】微分法。
  • phase : n 1 形勢，局面，狀態；階級。2 方面，側面。3 【天文學】（月等的）變相，盈虧；【物、天】相，周相，...
  1. But in the second phase, all of these theories can still be categorized into 4 kinds : dynamic comparative advantage theories, such as the new factors theories by baldwin and kenen, the life - cycle theory by vernon and hirsh, etc ; intra - industry trade theories such as product differentiation model by stiglitz and dixit, the strategy trade theory by spense, brander and krugman, and so on ; the endogenous trade theory such as technology overflow effect and learning curves theory by romer and krugman, the neo - classic trade theory by tucher and young, and the like ; and the competitive advantage theory by michael porter

    在這一時期，經濟學家們提出了形形色色的理論，出現了「百家爭鳴」局面。基本上可以歸于以下四大類型:一是動態的比較優勢理論;二是產業內貿易理論;三是內生國際貿易理論;四是競爭優勢理論。各個階段的比較優勢理論有其時代特點，但一個共同點是:比較優勢始於成本差異，並一直沒有突破成本差異，而不考慮產品的附加值。
  2. Eddy - current sensor conversion circuit consist amplification circuit, band - pass filter circuit, demodulation circuit, differentiation phase and data sampling circuit. these circuits are used to convert the test signal of eddy - current sensor to discrete signal tend to process. the microprocessor system that formed of dsp chip is used to data fitting of test system, data displaying and data communicating with personal computer, etc. the interference questions of hardware design and the measure of eliminating interference signal in the subject are introduced in the last of this chapter

    硬體電路的設計主要分三大部分來實現：激勵源電路部分，由分頻電路和頻率合成電路組成，產生頻率穩定的激勵信號以確保檢測任務的正常進行；傳感器變換電路部分，由放大電路、濾波電路、檢波電路、鑒相電路和數據採集電路組成，主要將電渦流傳感器檢測線圈檢測到的信號變換成只含有被測信息的離散信號，易於后續電路處理；由dsp晶元構成的微處理系統，主要完成檢測系統的數據擬合、顯示及與主機通信等功能。
  3. On the other hand, the activity and function of p27 kip1 was affected by many physiological agents such as camp, il - 2, rampamycin. the expression of p27kip1 increased after - irradiationin in the fibroblastoma cells, leading to arrest in gl phase, but its expression markedly decreased after y - irradiation in the nbcc cells, and leaded to arrest in g2 / m phase. several studies have reported that p27 kip1 involved in a much wider range of cellar processes, such as differentiation, apoptosis and migration, the expression level of p27kip1 is key for its function in dna damage responses

    另一方面， p27kip 』的活性水平及功能作用，因細胞類型不同而各異，又受多種因素的影響，如一些有絲分裂原camp 、雷帕黴素可以上調p27kip ，的表達，而il一2等則與p27ki 」 『的表達下降有關，受電離輻射（ ir ）照射的成纖維細胞瘤及用1 ， 25一二經基d3處理的hela細胞系在gl期均有游離的p27腳『的積累，細胞周期阻滯在gl期;而在痣癌伽bccs ）細胞中， y一射線能誘導p27吻『表達水平的顯著下調，細胞周期阻滯在g2艦期。
  4. Restin was a novel gene isolated by our lab from differentiation tumor cell induced by all - trans retinoic acid in 1999, and its molecular functions were not well understood. it mainly expresses in terminally differentiated cells. by transfection of restin into tumor cell, the cells were arrested in g1 phase and the cell proliferation was inhibited

    Restin是1999年本室在研究全反式維甲酸誘導細胞分化時克隆得到的一個人類未知功能的新基因，該基因主要表達于終末分化細胞，穩定轉染該基因的細胞出現g1期阻滯，抑制細胞的增殖，提示restin與細胞周期的調控有關。
