确实有很多实验啊, 我随便从google大学摘抄点. RE和flexibility负相关很容易理解
吧...
Several studies contend that flexibility affect RE (Godges 1989, Gleam 1990,
Craib 1996). Godges (1989) showed in athletic college students that RE
improved
with improved hip flexion and extension. This finding reflected the
empirical belief
that improved flexibility is desirable for increasing RE and may be
explained by an
enhanced neuromuscular balance due to the high flexibility, eliciting lower
VO2submax. Contrarily... 阅读全帖 |

Uranus-Neptune cycles
China
There is a fascinating relationship between Chinese dynasties and Uranus-
Neptune cycles. Dynasties loosely represent cultural-social periods in
Chinese history. Their rises, peaks and falls have an astrological
timeliness to them. The Qin, the first classical Chinese dynasty, who
established a unified imperial Chinese system from -221, probably started
hatching their plot around the conjunction of -233, just twelve years
earlier. The Early Han soon took ov... 阅读全帖 |

alternate law. Alternate law allowed AF447's horizontal stabiliser to trim
automatically 13° nose-up to avoid overspeed as the thrust was set to
maximum. Without manual re-trimming, the aircraft pitched up sharply as the
crew applied maximum thrust. It stalled and the crew lost control. |
