Macfarlane Burnety the two processes. The first one, which is forbidden in a vacuum but is possible in an intense external electromagnetic field, is the photon decay into the electron–positron pair .. We calculate the probability of this process in an external field, in the two limiting cases where the detailed anal栖息地 发表于 2025-3-28 23:32:50

Even under optimal conditions of culture, mutation is constantly occurring, and for certain types of mutant there are highly convenient methods of measuring mutation rates.Interregnum 发表于 2025-3-30 06:10:42
