breakdown cycle 中文意思是什麼
breakdown cycle
解釋
塑煉周期-
Protein kinase a is camp - dependent kinase, one of the most important signal transduction pathways, plays a pivotal role in growth, differentiation, tumor occur, cell cycle control, etc. pka activators such as camp, 8 - br - camp or phosphodiesterase ( pde ) inhibitor isomethyl butyl xanthine ( imbx ) or purified pka catalytic subunit all can inhibit germinal vesicle breakdown ( gvbd ) and meiotic maturation in mouse oocytes, also in xenopus oocytes
蛋白激酶a （ proteinkinasea ， pka ）是依賴于camp的絲蘇氨酸蛋白激酶，是重要的信號傳導途徑之一，廣泛參與許多生命過程，包括生長、分化、腫瘤發生、細胞凋亡、細胞周期調控等。以小鼠卵母細胞為實驗對象，給予pka激動劑camp 、 8 - br - camp或磷酸二酯酶抑制劑imbx （ isomethylbutylxanthine ）均可抑制小鼠卵母細胞的胚泡破裂及減數分裂成熟。 -
It is broken down by a reversal of the first two pathways, or by deamination to glyoxylate, followed by conversion to malic acid and further breakdown in the krebs cycle
它可在前兩種方法中被分解，或者通過脫氨作用生成乙醛酸，然後轉化為蘋果酸，進一步在三羧酸循環中被分解。 -
The sequence of two patterns presence is changed alternately, that is, one pattern will appear at the second pulse of total pattern in this half cycle if it appears at first pulse in last half cycle. the stability of square pattern was studied by considering the interaction among the wall charges. the discharge moments of individual filament alternate from long one to short in the square pattern, which can been explained by using the breakdown and quench model through considering the wall discharge accumulated on the dielectric layers
實驗研究了正方網格斑圖與混合氣體的比例及外加電壓的關系，給出了班圖類型隨上述條件變化的相圖；實驗採用光學方法對正方網格斑圖進行了時空動力學測量，發現正方網格斑圖是由兩套正方網格斑圖相互嵌套而成，其中一套的微放電絲位於另一套正方形單元的中心，這兩套微放電絲交替進行放電；考慮到壁電荷之間的相互作用，研究了正方網格斑圖的穩定性；實驗發現正方網格斑圖的微放電絲放電時間間隔是長短交替變化的，考慮到電介質表面積累的壁電荷的作用，使用擊穿?熄滅方程很好的解釋了該現象。 -
The results show that the final discharge in the last half cycle decided the first breakdown in this half cycle by analyzing the sequence among three current pulses in a half cycle
實驗分析了半周期有三次電流脈沖時放電的時序關系，發現上一個半周期放電的最後一個電流脈沖決定了本半周期第一次擊穿的時間。 -
Proper selection will eliminate one source of likely breakdown in the communication cycle
取詞正確的話，就等於消除了溝通過程中可能引起不暢的一個源頭。 -
Its operation frequency is 1. 38mhz, with an integration of a power mosfet whose breakdown voltage is up to 50v. the allowable input voltage ranges from 2. 7v to 5. 5v and its output voltage can be programmed between - 2v and - 15v, additionally, the output current is in a 200ma range in typical application. to avoid the poor efficiency of the pwm control scheme at light load, a skip - cycle - mode operation is introduced that allows system ’ s efficient operation at the light load
該電路工作頻率為1 . 38mhz ，內部集成耐壓50v的功率mosfet ，輸入電壓范圍2 . 7v 5 . 5v ，輸出電壓可在- 2v - 15v間連續可調，典型工作條件下輸出電流在200ma之內;同時，在輕負載下提供跳周期模式，具有很高的待機效率。
