1.It is shown that the pump parameter and intensity noise correlation time are the major factors of the first-order-like transition.
研究结果表明,抽运参量和噪声相关时间是激光系统出现一级相变类比的关键因素,角噪声相关时间对强度谱分布中的线宽影响较大。收藏指正
2.Abstract: A new variable structure model reference adaptive control (VS-MRAC) scheme is proposed in this paper.By transforming a relative degree one system into a first-order-like differential equation,it is shown that the SPR (Strictly Positive Real)assumption for reference model or its modified form(if plant relative degree n*>1)can be removed and the tracking error can converge to zero in finite time or a small residual set.
文摘:提出了一种可具有非严格正实参考模型的变结构鲁棒自适应控制方案,可去除变结构模型参考自适应控制中普遍要求参考模型为严格正实或当相对阶大于1时参考模型经补偿后为严格正实的假设.在此基础上提出的变结构控制律可保证跟踪误差在相对阶为1时于有限时间内收敛到零,而当相对阶大于1时则可使跟踪误差收敛到一个残差集内.收藏指正
3.The basin is controlled by four groups of fault (NEE, NWW, nearly EW, NW and the fault groups like letter X) which divided the basin into three first order structure units, including northern sub-basin, the central uplift and the southern sub-basin. The two sub-basins can be divided into smaller structure units, in which the Yining depression is the most favorable in Yili basin.
盆地演化主要受四组断裂带控制(NEE、NWW、近EW及NE、NW向X型剪切断裂带),将盆地分为三个一级构造单元,包括北部坳陷、中央隆起和南部坳陷,两坳陷进一步分割为更次级单元,其中伊宁凹陷是伊犁盆地中最具油气勘探前景的凹陷。收藏指正
4.Abstract: By compressing a monolayer film,the coexistence of liquid condensed (LC) and liquid expanded (LE) phases can be reached.The transition from LE to LC is usually regarded as a first-order one,so the theory of crystallization can be applied.In this article we review our recent studies on the growth of LC domains in the LE-LC coexistence region driven by the illumination of a fluorescent microscope.The mechanism of this unusual 2D domain growth phenomenon is discussed.The formation of faceted, dendritic and fractal-like domains as well as the evolution and the transition of these patterns are investigated.
文摘:当处于气液界面的类脂类化合物的单分子膜被压缩时,随着分子间距的缩小,单分子膜将经历一系列相变过程.通过荧光显微术可以观测到新相的成核和生长过程.由于单分子膜的二维特性,该系统中的实验观测对于检验和发展二维界面生长理论尤为重要.本文总结了近年来本课题组与相关单位合作,在单分子膜系统中发现的实验现象以及对其生长机制的系列研究.内容包括对单分子膜系统中的成核、界面稳定性、枝晶生长、形态演变等的观测和分析.收藏指正
