flux perturbation的意思|示意

With MCNP/4B code, the influence of cut-off energy, flux tallies, nuclear databases and perturbation on the reaction rates calculation with neutron-activation method are analysed.

用MCNP／4B程序，对核活化法反应计算中的截断能量、通量计数方式、数据库、阈探测器之间的扰动等因素的影响作了分析。

The method to estimate boundary heating flux according to the observation (single point or multipoint), is given with least squares and perturbation methods;

根据单点或多点测温，应用最小二乘及最佳摄动法，确定气动加热面边界热流密度。

This paper points out that the first-order perturbation photon flux produced by this system has not observed effect when GWs is different from frequency of Gaussian beam.

笔者指出，当入射引力波和高斯束不同频率时，高斯束谐振系统产生的一阶扰动光子流没有观测效应。
