cycle duration 中文意思是什麼
cycle duration
解釋
循環時間-
Constructing quantitative model with ordinary differential equations for the cell - cycle control system, it is appropriate to use ordinary differential equations ( odes ), because molecular diffusion, transcription, translation and membrane transport seem to be fast ( a matter of seconds ) compared with the duration of the cell cycle ( hours ). spatial localization of reactions can be handled by compart - mental modelling, in the spirit of pharmacokinetics
對于這樣的細胞周期控制系統，應用常微分方程是適合的，因為比起細胞周期的時間（以小時計）來，分子擴散，轉錄，翻譯和膜運輸是很快的（以秒計應用藥物動力學的區域化模型的方法，可以處理反應的空間分佈。 -
This isi series oscillation has following characters : ( 1 ) long term cycle duration, whose duration of most oscillations ranged from 3 0 - 120ms, so we called it slow wave oscillation ; ( 2 ) large amplitude of oscillation, the minimum isi is about 2ms while the maximum is beyond 40ms, which suggested that the firing frequency vary from several tens to hundred hz ; ( 3 ) abrupt turn always occurs during the continuous change in isi, this turn is called inflexion temporarily
該振蕩波有下述特徵： （ 1 ）振蕩周期較長，多數在30 ? 120s范圍，故稱慢波振蕩； （ 2 ）振蕩幅度較大，其isi振蕩最小值在zms左右，最大值可達40ms ，表明放電頻率可在幾十到幾百k范圍內變動； （ 3 ）在isi連續變化過程中往往出現突然轉折，暫稱其為拐點。 -
Data used in this work are north pacific ssta, 160 stations precipitation of china, and ncep reanalysis data. main results are as follow : ( 1 ) it is found that a apparent transition of north pacific ssta in later 1970 ' s : eastern and middle - equatorial pacific ssta turns from cold to warm with area extending, and mid - latitude pacific ( west wind drift zone ) turns from warm to cold. during this transition of ssta, different characters also appear in el nino and la nina : before 1976, la nina happens more frequently, and its duration is longer, el nino zone develops from negative ssta in the early stage ; after 1976, el nino happens a little bit frequent and longer with more intensity than before, el nino zone develops from positive ssta in the early stage ; the course of ssta variation has an enso cycle of 2 - 6 years, annual oscillation of 8 - 9 years, and decadal variation of about 22 years
本文採用1950 - 1999年北太平洋海表溫度（ sst ） 、中國160站夏季降水和ncep再分析的歐亞500hpa高度場等資料，利用eof 、 svd 、小波分析、合成分析和相關分析等方法，在分析北太平洋海溫時空分佈特徵的基礎上，著重探討了海溫異常及其年代際變化對我國東部降水的影響，並對降水、高度場和海溫三者之間的關系進行了分析，以試圖尋找三者異常之間可能的聯系，主要結論如下： （ 1 ） 1976年前後，北太平洋海溫經歷了一次明顯的轉變，赤道中、東太平洋厄爾尼諾海區由冷轉暖，暖水范圍增大，中緯度西風漂流區海溫由暖轉冷；在這樣的年代際背景下，厄爾尼諾、拉尼娜事件在不同的時期也有不同的特徵：在76年前，拉尼娜事件發生頻率高，持續時間長，事件起始於負海溫距平；而76年後，則是厄爾尼諾事件發生頻率略高，持續時間長，強度增大，事件起始於正海溫距平。 -
