In the scale of molecule , we cannot ignore the random collision between liquid molecules and motor . so the movement of motor has the features of brownian movement 在分子水平的尺度上,细胞液中的液体分子对马达的无规碰撞已经不能忽略,因此分子马达的运动具有布朗运动的特征。
Explicit iterated integral formulae of the moments in various order of the hitting times of geodesic spheres by brownian motions on rotationally symmetric manifolds are given in this paper 摘要主要给出了旋转对称流形上布朗运动关于测地球面的首中时、球壳的首出时的各阶矩的迭代积分公式。
On the assumption that investment fund follows geometric brownian motion , the pricing model of a short - period insurance contract that is affected by its investment profit is established 摘要在投资基金价格遵循几何布朗运动的假定下,对短期保险合同,建立了在投资收益影响下的保费定价模型。
By taking the image to be compressed as a grey - level surface of some fractal brown motion , the fractal dimension of this surface gives out a good description of its texture characteristics 把灰度图像看作是某种分数布朗运动形成的(分形)灰度表面,并用这种灰度表面的分形维数来刻画它的纹理粗糙程度。
The research is composed of feature extraction of workpiece surface texture and segment of tool wear image , which are based on the model of markov random field 工件表面纹理特征的提取以随机图像纹理模型为基础,分别研究了基于分数布朗运动理论和马尔可夫随机场理论的图像纹理特征参数的提取方法和应用。
He studied the i3rownian movement deeply 、 explained the photo electric successfully 、 gave the conception of the quantum hypothesis and founded the wave identification of a dual property of ray radiation 他深入地研究了布朗运动;提出光量子概念,创立了光辐射量子理论,成功地解释了光电效应;创立了狭义相对论和广义相对论等等。
The indicatorof the large screen is releasing a music scenery film , while small fluorescent balls ( simulated molecules ) are jumping along with the music to promote the balloons ( simulated pollens ) to start brownian movement 大屏幕显示器正在播放音乐风光片,模拟分子的荧光小球随着乐曲的节拍跳动,推动模拟花粉的气球进行布朗运动。
The smaller of particle size , the bigger of light scattering energy jumpiness , which reflects jje ( % hi } ) " " & " a ' ^ tjjij ri . ' ff - ' fe ift a " _ abstract that brownnian motion of small particle is more acute than big particle ' s ( 2 )样品静态测试中发现在7角处,颗粒粒径越小,能量跳动量越大,这与颗粒在液体中的布朗运动规律相符合。
Some main characteristics of the nano - fluids , such as stabilization and nanoparticle motion , are introduced . according to the theory of brown motion , the track of a nanoparticle is simulated 论文描述了纳米流体的基本特点,从胶体理论出发,介绍了纳米流体的稳定性;根据布朗运动理论,阐述了纳米流体的运动特性,模拟了纳米粒子的运动轨迹。
A centry ago , einstein published seccesively 5 theses on respectively quantum theory , special theory of relativity , brownian movement , etc , creating miracle in the field of pgysics and gave physics a brand new look 一百年前, 26岁的爱因斯坦相继发表了有关量子理论、狭义相对论和布朗运动等5篇论文,创造了物理学的奇迹,从根本上刷新了物理学的面貌。
