By comparing theoretical predictions with experimental data , one can obtain a valuable information on the form of the qq interaction potential . such information is of great practical interest , since at present it is not possible to obtain the quark - antiquark ( qq ) potential in the whole range of distances from the first principles of qcd 夸克势模型是其中重要的模型之一,它不仅能研究强子的基态,而且能研究激发态,但是,源于在中和大距离与qcd真空的复杂结构有关的非微扰特征,还不可能获得整个距离范围内的夸克?反夸克相互作用势。
Computational flow imaging ( cfi ) uses theoretical predictions of the interaction and transmission of optical waves through theoretical flowfield to generate digital pictures that simulate real observations . it was used to construct flow visualization corresponding to shadowgraph , schlieren , interferometric and planar laser induced fluorescence ( plif ) images . by providing a better insight into the flow physics and cfd code behavior , cfi is proving to be extremely useful to experimentally validate cfd codes 计算光学流动显示技术( computationalflowimaging - cfi )就是把数值计算( cfd )获得的流场中的物理场,经过与实验相同的计算光学(全息干涉、纹影、阴影、平面激光诱导荧光)的过程转换为所需的各个方向与试验流动显示图像相对应的计算流动图像。
