把規則剪貼過來
Section VII—Restrictions Governing Jump Balls
a. Each jumper must have at least one foot on or inside that half of the
jumping circle which is farthest from his own basket. Each jumper must
have both feet within the restraining circle.
跳球員至少有一腳在遠離己方籃框的半圈. 兩隻腳都要在圈內.
(換言之,可以有一隻腳踏到對方跳球員所在的半圈)
b. The ball must be tapped by one or both of the players participating
in the jump ball after it reaches its highest point. If the ball falls
to the floor without being tapped by at least one of the jumpers, one
of the officials off the ball shall whistle the ball dead and signal
another toss.
如果球掉到地上前沒人拍到,就重跳.
c. Neither jumper may tap the tossed ball before it reaches its highest
point.
球達到最高點後才能拍球.
d. Neither jumper may leave his half of the jumping circle until the
ball has been tapped.
球被拍到之前, 跳球員不得離開他的半圈.
(換言之,等球被拍到,跳球員就可以亂跑了)
e. Neither jumper may catch the tossed or tapped ball until it touches
one of the eight non-jumpers, the floor, the basket or the backboard.
跳球員在球碰到其他八人,地板等物之前，不能抓球.
（這邊動詞用catch, 應該是跟tap有區分.
而且跳球員本來就應該要能tap球才對
個人解讀是可以拍球不能抓球)
f. Neither jumper is permitted to tap the ball more than twice on any
jump ball.
跳球員不能拍球超過兩次.
g. The eight non-jumpers will remain outside the restraining circle
until the ball has been tapped. Teammates may not occupy adjacent
positions around the restraining circle if an opponent desires one
of the positions. No player may position himself immediately behind an
opponent on the restraining circle.
其他八人在球沒被拍到之前不能入圈.
(換言之,球被拍到之後應該可以衝進去搶)
Penalty for c., d., e., f., g.: Ball awarded out-of-bounds to the opponent.
h. Player position on the restraining circle is determined by the direction
of a player’s basket. The player whose basket is nearest shall have first
choice of position, with positions being alternated thereafter.
