【正文】 its construction and size of 30 in (76 cm) were ruled official in 1949. The rulesetters came from several groups early in the 1900s. Colleges and universities estab。 Australia, China, and India between 1895 and 1900。s original players were Canadians, and the game spread to Canada immediately. It was played in France by 1893。 the ball was the objective. To score, the ball had to be shot through a horizontal, elevated goal. The team with the most points at the end of an allotted time period wins. Early in the history of basketball, the local YMCAs provided the gymnasiums, and membership in the anization grew rapidly. The size of the local gym dictated the number of players。s Christian Association (YMCA), which later became Springfield College. Naismith (18611939) was a physical education teacher who was seeking a team sport with limited physical contact but a lot of running, jumping, shooting, and the handeye coordination required in handling a ball. The peach baskets he hung as goals gave the sport the name of basketball. His students were excited about the game, and Christmas vacation gave them the chance to tell their friends and people at their local YMCAs about the game. The association leaders wrote to Naismith asking for copies of the rules, and they were published in the Triangle, the school newspaper, on January 15,1892. Naismith39。s ball is in (7274 cm) in circumference. The covering of the ball is leather, rubber, position, or synthetic, although leather covers only are dictated by rules for college play, unless the teams agree otherwise. Orange is the regulation color. At all levels of play, the home team provides the ball. Inflation of the ball is based on the height of the ball39。s National Basketball Association (WNBA) playoffs. And it has also made American heroes out of its player and coach legends like Michael Jordan, Larry Bird, Earvin Magic Johnson, Sheryl Swoopes, and other great players. At the heart of the game is the playing space and the equipment. The space is a rectangular, indoor court. The principal pieces of equipment are the two elevated baskets, one at each end (in the long direction) of the court, and the basketball itself. The ball is spherical in shape and is inflated. Basketballs range in size from in (7276 cm) in circumference, and in weight from 1822 oz (510624 g). For players below the high school level, a smaller ball is used, but the ball in men39。t e naturally or easily to them, and so they are trying to follow a predetermined set of rules. Some individuals with autism have normal intelligence, and many have special talents in areas such as music or memory. However, individuals with autism may have other mental or emotional problems that coexist with their autism. Some of these other disorders may include impulse control disorders, obsessivepulsive disorder , mood and anxiety disorders, and mental retardation . PSYCHOLOGICAL AND FAMILY FACTORS. Although Henry Maudsley, in the late 1800s, was the first psychiatrist to focus on very young children with mental disorders, it was the psychiatrist Leo Kanner who coined the phrase early infantile autism in 1943. Kanner believed that the parents of children with autistic behaviors were emotionally cold and intellectually distant. He coined the term refrigerator parents to describe them. His belief that parental personality and behavior played a powerful role in the development of autistic behaviors left a devastating legacy of guilt and selfblame among parents of autistic children that continues to this day. Recent studies are unequivocal, however, in demonstrating that parents of autistic children are no different from parents of healthy children in their personalities or parenting behaviors. In fact, many families with an autistic child also have one or more perfectly healthy children. Because autistic children can be extremely sensitive to change, any change within the family situation can be potentially traumatic to the autistic child. A move, divorce, birth of a sibling or other stressors that occur in the lives of most families may evoke a more extreme reaction from an autistic child. While there is no single neurological abnormality found in children with autistic disorders, some research using noninvasive brain imaging techniques such as magic resonance imaging (MRI) suggests that certain areas of the brain may be involved. Several of the brain areas being researched are known to control emotion and the expression of emotion. These areas include the temporal lobe (large lobe of each side of the brain that contains a sensory area associated with hearing), the limbic system, the cerebellum, the frontal lobe, the amygdala, and the brain stem, which regulates homeostasis (body temperature and heart rate). Recent research has focused particularly on the temporal lobe because of the finding that previously healthy people who 中小企業(yè)融資現(xiàn)狀問題及對策 18 sustain temporal lobe damage may develop autisticlike symptoms. In animal research, when the temporal lobe is damaged, social behavior declines, and restless, repetitive motor behaviors are mon. When measured by MRI, total brain volume appears to be greater for those with autistic disorders. Other neurological factors include lesions to the brain, congenital rubella, undiagnosed and untreated phenylketonuria (PKU), tuberous sclerosis, and Rett39。正是由于他們，我才能在各方面取得顯著的 進(jìn)步。 中小企業(yè)融資現(xiàn)狀問題及對策 15 參考文獻(xiàn) [1] 張金穎 .關(guān)于中小企業(yè)項目融資現(xiàn)狀調(diào)查與加大中小企業(yè)項目融資比重的對策研究 [J].中國管理信息化 .2021(16):8389 [2] 金路 .淺議中小企業(yè)的財務(wù)管理 [J].中國商界 (下 ).2021(04):3237 [3] 李鑒君 ,徐向東 .我國中小企業(yè)融資的現(xiàn)狀、問題及對策 [J].會計之友 .2021(02):5859 [4] 孟青霄 .我國中小企業(yè)融資現(xiàn)狀分析 [J].市場論湯 .2021(06):4546 [5] 王淑梅 .金融危機下中小企業(yè)融資現(xiàn)狀、問題及建 議 [J].中國商界 (上半月 )． 2021(12):1921 [6] 王志剛 .中小企業(yè)融資現(xiàn)狀及對策分析 [J].時代金融 .(下 ):9697 [7] 彭桂蘭 .中小企業(yè)財務(wù)管理存在的問題及建議 [J].發(fā)展 .2021(02):5254 [8] 王德祥 .武漢大學(xué)學(xué)術(shù)叢書 [M].武漢大學(xué)出版社 .2021:231237 [9] 國家發(fā)改委中小企業(yè)對外合作協(xié)調(diào)中心 .中國中小
