    該兩級式變換器保留了上述單級式ppfc方案的基本優點，同時改善了其存在的幾點不足之處，具有相當的優越性，適用於本文所研究的燃料電池發電系統，文章最後通過模擬和實驗進行了原理驗證。
  4. Over - expression of yggg retarded the cell cycle, on the point after dna partition, resulting in accumulation of diploid as bacteria stop division and sequentially went to death. this appearance is similar to that of the era mutants, including the partially defective in era gtpase activity or the reduced in the synthesis of wild - type era which bacteria become arrested in the cycle at the predivisional two - cell stage

    在熒光顯微鏡下細菌形態的變化，以及dapi染色和透射電子顯微鏡觀察， yggg的表達與era突變（使era功能降低時）對細菌分裂的影響有類似之處，即細菌dna合成，子代dna分離后；分裂停滯，形成細菌繁殖受阻時， 2 - 4倍體的出現。
  5. Objective to investigate the effect of liuwei dihuang soft capsule and ginkgo leaf tablet on serum regulated upon activation, normal t cell expressed and secreted rantes in the patients with diabetes mellitus type 2. methods forty patients with early stage dm2 were randomly assigned to two groups, 20 in each group

    目的探討中藥六味地黃軟膠囊和銀杏葉片對2型糖尿病患者血清受活化調節由正常t細胞表達和分泌的趨化蛋白regulated upon activation ， normal t cell expressed and secreted ， rantes水平的影響。
  6. A lot of transcription factors such as atf, c - fos, c - jun, e2f and p53 were envolved in this stage. in this study, we try to identify the transcription factors interacted with restin by using mammalian cell two - hybrid system

    當細胞自靜止狀態的go期進入gi期時，眾多轉錄因子如燈f 、 e一fos 、 e一jun 、 ezf 、 p53等均參與這一進程。
  7. Based upon basic principles of the analog integrated circuit and theories of system stability, this paper deals with high precision, wide band - width and fully differential cmos operational transconductance amplifiers ( ota ). other than discussions about its performance evaluation and testing, a two - stage full differential ota has also been designed including its core cell and the overall layout

  8. We also stained the embryos with anti - arp3 antibody and found that these two kinds of antigen are generally co - localized but arp3 were not detected in cleavage stage embryos. it was deduced that cortactin functions in the cytokinesis independent of arp3. and microinjection of anti - cortactin antibodies into the i cell stage embryos leaded to fatal developmental defects because of the unequal cytokinesis

    在利用抗ap3的抗體進行的胚胎整裝染色中，激光掃描共聚焦顯微鏡觀察發現， arp3在卵裂期沒有表達， mbt后，在細胞皮層區檢測到arp3蛋白的陽性染色，在隨后的發育過程中arp3與皮層蛋白共分佈。
