The "cold fusion" phenomenon may be attributed to experimental errors
mistakenly indicating an excess production of energy. Those theories explaining
cold fusion require revisions in existing theories, and scientific skepticism
Line requires that unless the experimental evidence justifies belief in these miracles,
(5) one must conclude that experimental errors are being misinterpreted as positive
proof of cold fusion’s possibility. One would expect half of all careful energy-
balance measurements in cold fusion experiments to indicate excess energy, and
about half to show an energy deficit, because experimental error spreads the
results around the expected outcome. The recent preponderance of results
(10) showing excess energy might indicate something new, but if one is deliberately
searching for excess energy, then one may be able to "optimize" a complicated
system to yield large amounts of apparent excess energy by fooling the
measurement apparatus somehow. Whether a given excess-heat result
represents a physical "miracle" or an experimental error is very difficult to
(15) determine if the amount of excess heat is small or if the fraction of excess power
to total input power is simply too low.
According to the passage, the major reason that the evidence for the cold fusion phenomenon is suspect is
选项
A、no existing theory can explain the evidence produced by cold fusion experiments
B、the excess production of energy associated with certain cold fusion experiments owe primarily to experimental error
C、too many energy-balance measurements have indicated excess energy, instead of evenly distributed experimental error
D、the total input power in cold fusion experiments has been too low to draw solid conclusions about the fraction of excess power
E、scientists too often regard these experiments as proof of "miracles"
