Analyses show that refractive index changeinduced by thermal effect is similar to the change induced by other effects for linearabsorption,if laser pulse width is far less than the characteristic time of sample,i.e.refractive index change is directly proportional to spatial part of incident pulse laserintensity,so time averaged nonlinear refractive index can be defined.
结果表明,当激光脉冲宽度远小于被测样品的特征时间时,对于线性吸收来说,其热效应产生的折射率变化与其它效应产生的折射率变化有类似的形式,即与入射脉冲激光光强的空间部分成正比。因而可定义时间平均非线性折射率。在这种情况下,可用通常的Z-scan法进行非线性折射率及热光系数的测量,所得结论符合以前的实验结果。

First of all, retreat of glaciers and shrink of perennial snowbank induced by climate warming provide parent materials and spatial room for soil formation and development in the maritime Antarctica. Meanwhile, melt water originating from glaciers and snow-ice covers enhances temporal and spatial availability of free water, which plays all-important roles both in periglacial processes and the processes within soil profiles, thus influencing soil genesis and evolution to a great degree.

If his previous work could be categorized by being in between illustration and Contemporary art, his recent work can be described as shifting and committing completely to the presets of Contemporary art. Deva Loka, an epic project Amano eagerly created with much drive. Deva Loka, a work that was crystallized through much time and imagination, carries significance because it encompasses Amano's world of art. The main concept for this project is the Big Bang, a phenomenon that brought about all the planets in space.

The shorter of interruption duration, the more obvious interruption effects, and this support the motion opponency theroy. 3 The different intervals between priming and target were detected. Due to interruption of blank frame, the shorter interruption elicited positive proming effects, which is consistant with integration of temporal and spatial in the human brain. 4 The negative of the same direction is relationship to visual adaption and visual inertia effects.
本系列实验得到以下主要结果与结论:1插入空白图片,将导致特定运动方向的反转,而对二义的运动没有明显影响,反映了空白图片对正常视觉运动的阻断;2阻断时间越短,导致特定运动方向反转的几率越大,即阻断效应越明显,支持运动知觉对立理论;3考察不同间隔的启动——靶刺激,由于空白刺激的插入,启动——靶刺激间隔较短时引起的正性启动效应,与人脑系统对视觉信号的时间与空间整合和视觉惯性是一致的。4同向运动的负性倾斜效应与视觉适应有关。

We have concluded five key tectonics geologic characteristics of Chinese foreland basins based on the study of the sedimentary infill, tectonics evolution, tectonic dynamics, spatial location distribution and structural deformation geometry.(1) The foreland basin is the superimposition of the compression sedimentary stratigraphic sequence with the extension basin, and the foreland basin includes underlying rift basin and upper dustpan flexure deposited basin.(2) The foreland thrustfold structural deformation has occurred four times since the Protozoic, in the Late Caledonian, Late Hercynian, Indosinan and Late Himalayan, respectively.(3) The foreland basin developed based on the control of two factors that are the basin basement collaged by many small plates or terrains and the rejuvenation of ancient orogenic belt, so the foreland basins or foreland thrusts are located in front of ancient orogenic belt.(4) The foreland basins and the rejuvenation of ancient orogenic belt make up a giant basinmountains system resulting from the distant effect of IndiaEurasia collision, which is located on the outer circle of Tibet Plateau, so the thrust deformation intensity, basin deposition range and coupling between orogenic belt and basin changed from strong to weak as from interior to outer circle of Tibet Plateau.(5) There are many structural styles of the thrust and fold belt in different basins, such as brittle behavior faultrelated fold, ductile behavior basementinvolved structure, basementinvolved faultrelated fold, and salt structure.

Only with such characteristics, the movement equations can be expressed as matrices, and the idea of transforming the movement equations to the simplest form through a nonlinear transformation can be realized;(2) The form of Zi =Yi + YTH2i Y + Y7H3i Y(2)+ Y(2)T H4i Y(2)+ YTH5i Y(3) is adhibited in the nonlinear transformation, so that the multivalued problem caused by the nonlinear transformation is avoided, and the higher order transformation can be taken next;(3) The fourth order nonlinear transformation matrices H21,H31,H41 and H51 are derived, by which the original movement equations of electric power system is transformed to Jodan form in Z space;(4) By use of the fourth order nonlinear transformation, the approximate expression of the stability boundary is obtained, in Z space it is Z1= 0,in Y space it is Y1 + YTH21 Y + YTH31 Y(2)-i- Y(2) TH41 Y(2)+YTH51 Y(3)= 0;(5) The criterion used in this paper to judge whether the system critical unstable is simple and quick;(6) The method used in this paper is a direct method, and no need to construct an energy function.
正是由 于电力系统的运动方程具有这样的特性,才能写成矩阵的形式,通过非线性变换将电力系统的运动方程变换为最简单的线性形式的思想才能得以实现;(2)将通常运用于电力系统暂态稳定性分析的Normal Form变换的形式由 Yi= Zi+ ZTh2riZ变形为 Zi= Yi+YTH2iY+YTH3iY(2)+Y(2)TH4iY(2)+YTH5iY(3),从而使得在对持续故障轨线实施同样的非线性变换以确定临界切除时间时,避免了非线性变换带来的多值性的问题,而只有在没有多值性问题的困扰下,才能采用较高阶的变换:(3)推导出了将原始电力系统系统的运动方程变换到Z空间的约当形式的非线性变换矩阵H21、H31、H41、HS1:(4)在运用四阶了「线性变换的情况下,给出了受扰动后系统的稳定边界的近似的解析表达,在Z空间为Z1=0,在y空间为: Y1+YTH21Y+YTH31Y(2)+Y(2)TH41Y(2)+YTH51Y(3)=0 (5)确定临界失稳的判据简单、快捷:对于一个复杂的电力系统,其稳定边界是相当复杂的一个高维曲面,即便是已知系统稳定边界的解析表达,要求出系统持续故障轨线何时与这一高维曲面相交,在数学上几乎是不可能实现的。
