LAMMPS的velocity设置

请问一下,如果LAMMPS的velocity命令设置为:velocity  group-id  create  temp  seed dist uniform,那么生成的速度是不是该温度下的方均根速率?

LAMMPS的说明书只是说:

'The create style generates an ensemble of velocities using a random number generator with the specified seed at the specified temperature.'

'The dist keyword is used by create. The ensemble of generated velocities can be a uniform distribution from some minimum to maximum value, scaled to produce the requested temperature.'

    问题本身就不通顺

    不过可以这样理解

    "dist uniform" means that the initial velocity components do not form a Gaussian (Maxwell) distribution but will approach
    it afterwards. If you are interested in the statistical properties of the initial velocities, you need to study a little about probability distribution,

    OK, thank you !
