In December 1936, Hank Luisetti of Stanford revealed the virtues of the onehanded shot to an amazed Garden audience and became the first major collegiate star. Soon thereafter, Luisetti scored an incredible fifty points against Duquesne, thus ending the East39。s skills. Despite the pointshaving scandal, college ball thrived in the 1950s, largely because it had prolific scorers and more great players than in any previous decade. Frank Selvy of Furman and Paul Arizin of Villanova both averaged over forty points early in the decade, while Clarence Bevo Francis of tiny Rio Grande College in Ohio amazed fans by scoring 116 points in one game while averaging 50 per game for a season. The decade also witnessed some of the most talented and plete players ever. Tom Gola at LaSalle, Bill Russell at San Francisco, Wilt Chamberlain at Kansas, Elgin Baylor at Seattle, Jerry West at West Virginia, and Oscar Robertson at Cincinnati, all had phenomenal skills that have since been the measure of other players. And in 1960 one of the best teams ever, Ohio State, won the NCAA title led by Jerry Lucas and John Havlicek. Professional basketball underwent major changes in the 1950s that helped increase its popularity. In 1950, Earl Lloyd, from West Virginia, played for the Washington Capitols and became the first African American to play in the NBA. In 1954, Danny Biasone, owner of the Syracuse Nationals, persuaded the NBA to institute the twentyfoursecond shot clock, requiring a team to shoot within that time. This eliminated the slow pace that had long prevailed in the pros and made the NBA more exciting. Teams now scored one hundred points a game regularly. The league also now awarded foul shots when the other team received more than five personal fouls a period, greatly reducing the rough play that had hurt the pro game. In 1956, Red Auerbach of the Boston Celtics made the best deal in NBA history when he acquired the draft rights to Bill Russell, the defensive player and rebounder he needed to plement Bob Cousy and Bill Sharman in the backcourt. With the addition of Russell, the Celtics became the best pro team ever, winning eleven of the next thirteen championship titles before expansion diluted the talent in the NBA. The St. Louis Hawks, with Bob Pettit, beat the Celtics in 1958, and the Philadelphia 76ers, with Chamberlain, beat them in 1967. But Russell, a playercoach for two titles, and his teammates formed the greatest dynasty in pro ball. Even the Los Angeles Lakers, who had moved from Minneapolis in 1960, with West and Baylor, were no match for the Celtics over these years. While West, Baylor, Chamberlain—who averaged over fifty points a game in 1962—and Oscar Robertson—who in the same year averaged a triple double per game in points, assists, and rebounds—were superior to any individual Celtic, no other team could consistently play defense, rebound, and run with the Celtics. 。s Harlem Globetrotters, which was actually from Chicago. While these teams had some notable players, no superstars, such as Babe Ruth, Jack Dempsey, or Red Grange, emerged to capture the public39。s professional leagues were attempted and failed, including the Women39。 and Japan in 1900. From 1891 through 1893, a soccer ball was used to play basketball. The first basketball was manufactured in 1894.

The dedicated basketball was made of laced leather and weighed less than 20 oz (567 g). The first molded ball that eliminated the need for laces was introduced in 1948。s bounce. Inside the covering or casing, a rubber bladder holds air. The ball must be inflated to a pressure sufficient to make it rebound to a height (measured to the top of the ball) of 4954 in ( m) when it is dropped on a solid wooden floor from a starting height of 6 ft ( m) measured from the bottom of the ball. The factory must test the balls, and the air pressure that makes the ball legal in keeping with the bounce test is stamped on the ball. During the intensity of high school and college tourneys and the professional playoffs, this inflated sphere mands considerable attention. Basketball is one of few sports with a known date of birth. On December 1, 1891, in Springfield, Massachusetts, James Naismith hung two halfbushel peach baskets at the opposite ends of a gymnasium and outlined 13 rules based on five principles to his students at the International Training School of the Young Men39。 fppFtf ?? ? ? ?? ? ? ? ? ? ? ?039。 令 ?iez? ，則 izz 2sin 1???? ， 2cos 1??? zz? ，izdzd ??。 注意展開的區(qū)域，在展開點的所有解析區(qū)域展開。故將函數(shù)在解析點的鄰域中展開冪級數(shù)一定是 Taylor 級數(shù)。 二、復(fù)變函數(shù)積分的計算方法 沿路徑積分： ? ??c dzzf 利用參數(shù)法積分，關(guān)鍵是寫出路徑的參數(shù)方程。 冪函數(shù)與根式函數(shù) ????? innnnnn erninrirzw ?????? )s i n( c o s)s i n( c o s 單值函數(shù) n kzinn erzw ?2ar g1 ???
