cyclic evolution 中文意思是什麼
cyclic evolution
解釋
完整演化周期-
We calculate a model with angular momentum loss caused by gravitational radiation, and find that the binary undergo cyclic evolution as well. however, the period of the cycle becomes shorter, and the ratio of the time spent in the semi - detached phase to the time spent in the contact phase in a cycle becomes smaller
我們計算了由引力波輻射引起雙星系統的角動量損失的演化模型，發現雙星系統還是經歷循環演化，不過循環的周期變短，且雙星系統的每一個循環處在半接狀態的時間與處在相接狀態的時間之比變小。 -
With time - evolution - operator, it is proved that the population of upper level is in circumstance of cyclic oscillation by laser pulses pair of gaussian line - shape in a homogeneous broadening two - level system. the oscillatory time oxide is the delay time between the laser pulse pairs and the oscillatory frequency equals the one of transition between the lower and upper level
引入時間演化算符，證明均勻增寬二能級體系在飛秒激光脈沖對作用下上能級激發態布居是周期性變化的，它以飛秒脈沖對之間的延時為時間軸，以該原子能級之間的躍遷頻率為振蕩頻率 -
By studying the rule of damage evolution and remaining life under conditions of two level cyclic loading, it is considered that damage evolution and remaining life of specimen are dependent strongly on damage and hardening state caused by loading history, under multi - level cyclic loading
通過對兩級循環加載下損傷演化規律和剩餘壽命的研究，認為在兩級（或多級）加載條件下，材料的損傷演化和剩餘壽命強烈地依賴于加載歷史造成的損傷和硬化狀態。 -
At last, take a three - storeyed and two - span reinforced concrete frame as example, its damage value under cyclic load at different time is computed by the program. and the damage evolution curve of different element and whole structure is also obtained. as result the damage evolution law of reinforced concrete structure under cyclic load is found, which provides basis for the study of collapsing mechanism of reinforced structure under seismic force
最後，以一個三層兩跨的鋼筋混凝土框架為例，應用作者自編的程序計算了循環荷載作用下該框架結構在不同時刻的損傷值，並給出了其不同構件及整體結構的損傷演化曲線，揭示了循環荷載作用下鋼筋混凝土框架結構的損傷演化規律，為地震力作用下鋼筋混凝土結構的倒塌機制問題的研究提供了依據。 -
Experiment of hydrogen evolution showed that the evolution hydrogen amount of current collector coated by mono - layer plating or double - layer plating was less than without them in 7. 0m koh solution with zinc power, and that of the double - layer plating of zn - in, sn - in was the least. cyclic voltammetry - indicated that there is an obvious reduction peak of hydrogen at the potential of about - 0. 8v vs
用動態析氫實驗表徵，發現沉積單、雙層金屬的集電體在含鋅粉的7 . 0m的氫氧化鉀溶液體系中的析氫量比無沉積層的銅集電體析氫量要小，其中，沉積鋅銦、錫銦雙層的析氫量最小。
