As another example, cosmic rays have a wavelength of lessthan a millionth of a millionth of an inch, while some radio waves have wave lengths of over a mile!
再举另外一个例子,宇宙射线的波长不及万亿亿分之一英寸,而某些无线电波的波长却超过一英里!
Two ideas are worth notice in the adiabatic scenario (assumed that the initial perturbations are adiabatic) : 1. The idea of the cosmic density wave.
在绝热密度扰动(假定初始扰动是绝热的)的方案中,有两种观念特别值得注意:1,宇宙密度波的观念。
The propagation effect of VLF wave could become a useful tool of detecting the intensity variation of cosmic rays.
所以,VLF波的传播效应可能成为间接探测宇宙线强度变化的有用工具。
