This is equivalent to the difference between stable and unstable equilibria. Prices typically remain stable in terms of other relatively stable currencies. It was very stable but extremely expensive. This species occurs in relatively stable groups. It is thermodynamically stable and fairly soft metal. Compared to rotation matrices they are more compact, more numerically stable, and more efficient. Otherwise it is volatile, highly stable, and nonflammable. The Reichsbank experienced both stable and volatile periods . This observation of greater delocalization in less stable molecules is quite general. This leads to a more stable power system. He was reported to be in stable condition. Depressurization helps to make open pit mines more stable and secure. Fluorine has one stable and naturally occurring isotope, fluorine-19. New Zealand is identified as one of the world's most stable and well-governed states. Glucose may be labeled with either stable or radioactive atoms.
