【 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.
