Memorize numbers module — In this task, subjects must recall numbers that are given at baseline, then carry out an arithmetic "distractor" task, then reproduce the numbers given at the outset."If you have 2 numbers, it's easy, but if you have 10 numbers and then a distractor task, your working memory is working very hard to get this information," Dr. Penner notes.

记数模组—在这个任务中，受试者必须记住一开始给予的数字，之后进行算数诱答任务，接著再现一开始给予的数目；Penner博士指出，如果你有两个数字，那是简单的，但是如果有10个数字，然后进行诱答任务，你的操作记忆会难以得到此资讯。

Based on the nonlinear dispersion relation of electromagnetic wave in relativistic plasma, the nonlinear controlling equation for linearly polarized mode is obtained using Karpman's method. The modulation instability of intense laser pulse propagating through relativistic plasma is analyzed and the modulation instability growth rate as a function of perturbation wave number for laser beam propagating through relativistic plasma is given.
