摘录自一个十年前对用球的研究:
http://steroids-and-baseball.com/changing-baseball.shtml
弹性: Platek and Gregory conducted another series of bounce tests on the pills;
the scientists conducted about 20 drops with each. They found that the average
height of the bounces from the 1995 and 2000 pills, when dropped from a
height of 182 inches, was 83 and 82 inches respectively. None of the pills
from 1963, 1970, and 1989 averaged over 62 inches. The newer pills each
bounced at least 1/3 higher than the older ones.
结构: The URI study showed that baseballs from two well-separated years in the
post-1993 era (1995 and 2000) were very like each other, yet very different
from balls from pre-1993 years; it also showed significant categorical
differences between the older Spalding and newer Rawlings balls. The Penn
State study showed a marked increase in zip from 1977 on. All that agrees
with the stats-indicated and common-sense indicated belief in a big jump when
the ball maker was changed between 1976 and 1977, as well as the belief that
there was a subsequent jump starting in 1993 and in full force in 1994.
