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。

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