Around 40 ; the neutral curve obtained by the growth rates of the temperature fluctuation has a ringlike curve separated from the main branch of nachtsheim s calculation by velocity fluctuation at the lower grashof number side ; and its phase velocity is close to the maximum mean velocity where the critical layer of the eigenmode locates. the thermal fluctuation decays rapidly as the nondimensional frequency above 0. 4, so that it means that the coupling effect between instability wave generated by buoyancy fluctuation and velocity waves by invicid instability seems weak enough for their critical layers in the range of the nondimensional frequency

科學發展的非線性觀立足點就在於科學是社會系統的分系統,它不僅有非線性相互作用,這構成了發展的源泉和動力,更有導致無序中產生有序的奇異吸引子(科學問題與科學理論, 「馬太效應」與「優先權」 ) ,在發展過程中對初始條件也具有敏感依賴性,並受到系統內部、外部的各種隨機因素的影響而產生漲落,在常規發展時期表現為科學的漸變,也就是量的積累,當漲落放大時就表現為科學革命,即質的改變。Therefore the emergence and development of the culture of science and technology can be traced back to the initial conditions of geography and climate, viewed as the factor of internal fluctuation from the sensitiveness of the random choices of the cognitive subject to the initial conditions. since a culture has a pivotal component as its core, once the culture of science and technology comes into being under nonlinear interactions of the social subsystems, the core component functions in the same manner as order parameter in the self - organization system, immensely attracting, regulating and controlling others under the slaving principle. and thus the analysis provides a nonlinear approach to the needham ' s problem
對于任何思想文化傳統而言,其形成和延續都有其現實的物質生活的根源,因而,對于科技文化的產生和發展,我們能夠返回到其發生的原點? ?即地理氣候等初始條件,從認知主體的隨機性選擇對初始狀態的敏感性方面,視其為科技文化產生的內漲落因素,考察其對科技文化形成的影響;而一種文化之所以稱其為文化,必有其全局控制力的核心因素,科技文化是在社會各子系統非線性的相互作用下形成,其核心因素所發揮的作用就如同序參量在自組織系統中的作用那樣,在支配原理的作用下起著規范、引導和支配等效用。The 2 - point self - energy and 3 - point vertex correction in < j ) 3 theory are calculated in this rule, and the fluctuation - dissipation theorem for 3 - point nonlinear response function is verified

分析得到了潮灘水動力基本特徵:光灘水位漲潮和落潮時間基本相等,而鹽沼前緣帶水位漲潮時間略短;光灘流速過程線在漲潮初和落潮末出現峰值,呈現「雙峰型」特徵,鹽沼前緣帶則冬、春季節呈現「雙峰型」 ,夏、秋季節落潮峰值消失,鹽沼帶四季呈現單峰特徵,潮溝內過程線為「雙峰型」 ;各測點流向均呈現回轉流特徵,在高水位時流向迅速改變,不存在明顯的憩流。The analytical solutions of the gain, dispersion and population difference in the steady state of an open ladder lasing without inversion ( lwi ) system are at first given when the phase fluctuation of the driving field is considered. then the effects of the driving field phase fluctuation on the gain, dispersion and population difference are analyzed by the numerical results from the analytical solutions. our research shows that the phase fluctuation of the driving field will results in a finite line width ; with the line width increasing, the gain decreases monotonously, however, variation of the dispersion isn ? t monotonous, it has a maximum value when the line width takes some value ; the line width varying can ? t lead to change lasing from without to with population inversion
給出了有驅動場位相漲落的開放的梯型無粒子數反轉激光( lwi )系統增益、色散和布居數差的定態解析解,進而用得到的數值計算結果分析了驅動場位相漲落對增益、色散和布居數差的影響.研究結果表明,驅動場位相漲落將導致有限線寬;隨著線寬的增加,系統增益單調地減小,但系統色散的變化並不是單調的,當線寬取某個值時,色散有極大值;線寬的變化不能導致無反轉激光向反轉激光的轉變The urban resource - environment system is a dissipative structure with the characteristics as follows : openness, far from equilibrium, complicated non - linear interaction within the system, fluctuation and abrupt change

在此基礎上,從東西方科技文化的發生和起源入手,從耗散結構的觀點出發,考察了認知主體的隨機性選擇這種文化的內漲落因素,是怎樣依託于各自不同的初始條件?地理氣候條件,在自然觀、物質觀和思想模式方面一步步得到正反饋式的放大;進而,在文化系統內部種種非線性的相互作用下,從競爭和協同所必然產生的序參量和吸引子兩個方面,分別考察了東西方科技文化不同的發展規律,聚焦東方的實用化取向和西方的思辨化、技術化取向的影響機制,從它們在不同時期所發揮的不同作用正面回答了「李約瑟難題」 。Various important effects brought by noise in nonlinear systems, such as noise inducing phase transition, stochastic resonance, nonequilibrium fluctuation - induced transport, open up a wide range of applicability of the stochastic theory
