| 1. | In all quantum mechanics system , quantum geometric effect and geometric phase hold a very important role 在整个量子力学系统中,量子几何效应和几何相位占据着很重要的地位。 |
| 2. | Most of students are not interested in quantum geometric effect because it is a nodus . yet no innovations can be found 量子几何效应历来又是教学中的一大难点,造成不少同学对此部分没有兴趣,更谈不上有什么创新了。 |
| 3. | Firstly , several familiar quantum geometric effects and the discovery processing and current states of geometric phase are introduced in this paper 本文中首先介绍了几种常见的量子几何效应以及几何相位的发现过程和研究现状。 |
| 4. | At last , i briefly discussed how to cultivate students " creative ability using the ideas of constructivism during the course of teaching 本文根据建构主义的思想,结合教育理论就如何在量子几何效应的教学中培养学生的创造性思维进行了讨论。 |
| 5. | Finally , convergent geometry had an important effect on the perturbance coupling between the interfaces of the finite fluid . the attenuation factor of perturbance coupling from the outer interface in was greater than the one from the inner out 本文研究表明:收缩几何效应对有限厚度流体的界面之间的扰动耦合有重要影响,柱和球几何中扰动耦合从外界面到内界面的衰减因子大于从内界面到外界面的情况。 |
| 6. | For example , the geometric effect and vignetting are simulated with the synthetic method in which they are modeled with ray tracing and then simulated with pixel - based processing . the effects of detector noise on imaging are simulated with the three - dimension model . the theory of pixel transfer function is extended and developed , and microscanned images of four patterns are simulated with good results 本文具有如下几个突出特点:用光线追迹法分析建模,而用基于象素处理的综合方法,模拟了光学系统中的几何效应和渐晕现象;利用三维噪声模型,模拟了探测器噪声对图像质量的影响;对象素传递函数理论进行了扩展和延伸,给出四种工作模式的微扫描成像系统的象素传递函数的具体数学表达式,并利用这些表达式模拟了探测器的空间效应和微扫描成像的图像效果。 |
| 7. | The strength of convergent shock was enhanced in cylindrical and spherical geometries than in planar geometry . the bubble became more wide and big and the spike became more narrow and long . it showed in spherical implosion that the spike close to the symmetrical axis grew faster than the ring one away from the symmetrical axis 第四,利用lared一s程序模拟柱和球几何内爆过程中rt不稳定性增长,表明收缩几何效应对内爆过程中不稳定性的增长有重要影响,柱和球几何中聚心冲击波的强度大于平面情况,气泡变得更加宽而大,而尖顶变得更加细而长。 |
| 8. | Secondly , nonlinear threshold of two - dimensional rt instability was analyzed in planar and cylindrical and spherical geometries . density amplitude was defined relating to instable interface and formulae of nonlinear threshold values for rt instability in three geometries were given , then the lared - s code was used to simulate two - dimensional rt instability in three geometries and simulation results agreed well with the formulae 其次,讨论了二维平面、柱和球几何中rt不稳定性发生非线性偏离的阈值问题,给出了三种几何中密度扰动振幅的非线性闭值公式,并且用lared一s程序进行了检验,计算结果表明柱和球几何中的模藕合机制与平面几何不同,存在几何效应的影响。 |
