It has been shown that : the little indentation which represents the quantum noise of the system appears in the evolution curves ; the quantum noise which is caused by virtual photon field gradually becomes weak when w increases, the quantum noise increases when n increases ; the virtual photon process make the antibunching effect strengthen, make the squeezing degree deepen obviously, and lead to the additional vibration of entropy, the oscillation extent of the additional vibration of entropy increases when n increases and decreases when co or g increase. besides, the quantum dynamics of two coupling atoms interacting with a single mode ligh t field in a kerr medium is studied in this paper ; the influences of the kerr effect on the mean photon number, the degree of second order coherence of field, the evolution of the field entropy and the squeezing effect are also discussed
）的增大，量子噪聲分別減小和增大；虛光子過程使光場的反聚束效應增強，使光場的壓縮程度明顯加深，並引起了附加的「熵振蕩」 ，這種附加「熵振蕩」的幅度將隨著光場初始平均光子數（ ? ）的增加而增大，隨著光場頻率和原子間耦合系數g的增大而減小。本文還研究了充滿kerr介質腔中「耦合雙原子-單模光場」相互作用系統的量子動力學性質，研究了克爾效應對場的平均光子數、二階相干度、場熵演化特性及光場壓縮效應的影響。 -

將上述命題演繹和整合成一種廣泛適用於地質系統的地球科學的復雜性理論，名之為： 「地質作用的自組織臨界過程動力學? ?地質系統在混沌邊緣分形生長」 ，並將其內容歸納成6部分： （ 1 ）自組織臨界性、瞬態混沌、混沌邊緣和弱混沌， （ 2 ）多組分的耦合與相互作用及其相干與協同， （ 3 ）演化過程的分形動力學， （ 4 ）作用的時空結構， （ 5 ）分形生長動力學， （ 6 ）有限大小標度理論。 -
The adsorption of polymer chains at the sio2 surface avoided the coherence between the nascent hollow fibers, improved spinning conditions and hollow fiber bearing. the addition of ca further improved mechanical property of membrane, but pressure - resiposivity became weak. by controlling polymer and sio2
通過對sio _ 2填充pu溶液紡絲成形研究發現，因sio _ 2對pu紡絲液相分離條件的改變及對pu大分子的吸附，有效防止了pu初生纖維的粘結，提高了pu紡絲溶液的可紡性，改善了pu中空纖維膜的支撐性。 -
Under the condition of " comparatively weak correlation between the two noises involved, coherence function is used as a frequency domain amplification factor for improving snr of the output signal to the filter and the speech enhancement effect. meanwhile, a real - time recursive algorithm is put forward in substitute for current algorithms based on short time fourier transform. the new algorithm will simplify computations and will be suited for real - time implementation together with the adaptive systems
接著針對上述nanc系統兩路輸入信號噪聲相關性弱的情況，用相干函數作頻域增益因子來提高輸出信噪比與改善語音增強效果，同時，通過一種實時迭代演算法解決了短時傅氏變換計算量大的問題，簡化了計算，便於實時處理與實際應用。 -
Abstract : one of the unsolved problems of the high power application of high temperature superconductors is how to lower the energy dissipation induced by flux motion. due to the extremely high anisotropy, small coherence length and weak pinning potential, the mixed state phase diagram which is tightly related to the flux dynamics becomes very complicated. a brief account is given of the field induced crossover of criticalities of energy dissipation, which has been observed in our recent sensitive electromagnetic measurement
文摘:高溫超導體在強電方面應用的關鍵問題是如何克服磁通運動所造成的能量損耗.由於存在極強的各向異性、短的相干長度和小的磁通釘扎勢，因此與磁通運動緊密相關的混合態相圖變得很復雜.文章綜述了根據一系列靈敏的電磁測量所觀察到的磁場誘導的能量耗散行為的轉變
