漸減函數 的英文怎麼說
中文拼音 [jiānjiǎnhánshǔ]
漸減函數
英文
decrescent function-
It is found that in the absence of dissipation and average photon number of the reservoir the linear entropies of the atom and the field varies with time periodically, going to zero at the disentanglement times, and the period is the same as that of bell function and the linear entropy of the total system is zero at any time. if the cavity dissipation and the average photon number of the reservoir is taken into account, the linear entropies of the atom and the field present local maxima and minima and the difference between them diminishes with time, tending to asymptotic values
結果表明，在忽略腔損耗和熱庫的平均光子數時，原子和場的線性熵有周期性的變化，在沒有糾纏的時刻，值為0 ，此時的周期與bell函數相同，而系統的線性熵在任何時刻都為0 ；如果考慮到腔場的損耗和熱庫的平均光子數，原子和場的線性熵有局部的最大值和最小值，它們之間的差距隨時間逐漸減小，趨向一個漸進值。Life time of mn2 + in nano - zns was measured and was found to be close to that of the bulk materials. therefore the quenching centers quench the exciton but not the mn2 + ion self. 2. the increasing curves are different in film and ethanol colloids because there is diffusion process of quenching centers in colloids
對薄膜樣品的熒光增強曲線的擬合表明，顆粒表面猝滅中心數目隨輻照時間的衰減函數是非e指數形式;同時考慮溶液中猝滅中心通過向顆粒表面的擴散而逐漸耗盡，很好地解釋了溶膠的增強曲線與固體薄膜的增強曲線的不同。Our results show that the optimal value with a parameter is a monotone decreasing sectionally continuous linear function g about parameter a, and the membership function of fuzzy objective sets are a linear function, written as c
經過研究發現，其最優值是隨著參數減少而逐漸減少的分段連續的線性函數g 。另外，模糊目標集的隸屬函數也是一個線性函數，記為c 。In this thesis, firstly, we introduce generalized gaussian distributions to model the distributions of dct coefficients of an el frame. then, according to quantization theory, we analyze the distortion - rate function of the generalized gaussian model, with which we conclude that for the actual fgs coding, the derivative of actual distortion - rate function usually decreases continuously as the rate increases, and then begins to increase slowly at a comparatively high bit rate. finally, guided by the
然後分析了fgs編碼的量化模式，並把它應用到ggd分佈上，得到了ggd分佈率失真函數的變化規律，從而獲得實際fgs編碼的率失真函數的變化規律，即fgs編碼失真速率函數的導數先隨著碼率的增加而逐漸減小，然後在碼率比較高的時候開始隨碼率的增加而緩慢地增加。分享友人
