【 摘 要 】

Here I present some well known relationships that allow the variation in critical mass versus density to be written in a simple analytical form; these relationships have appeared extensively in the open literature for over 50 years, but seem to be periodically forgotten. These relationships are exact for bare, homogeneous systems, and approximate [but reasonably accurate] for reflected systems. With these relationships anyone can quickly estimate the critical mass corresponding to any given density, using nothing more complicated than a hand calculator.
