5Under powerful offensive denfense,failing in resolving the offending problems is one of the leading reasons that it lost in the world men ' s basketball championship;the quantity of the fast attacks from chinese team lags behind a lot,compared with the opponents.Moreover,the difference of the quantity of success,the gap of score and fast attacks after stealing is very obvious; scoring could only be attributed to receive and shoot,play by oneself and free throw.Scoring method is simple and unscattered;strategic offenses lag behind the opponent obviously.Both free throw after active offense and rebound control could not defeat the rivals.The stealing and offense succeeding percentage also fall behind. The offense efficiency lags more behind;the number of two – piont shot lags behind the opponent while the field goal percentage ranks a little higher than opponent.The number of three-point shot is similar, but the field goal percentage is obviously different;chinese team ' s front court rebound falls behind the opponent apparently.However,the second offense scoring is a little higher;chinese team ' s assists lags behind a lot;chinese team ' s stealing lags behind a lot;chinese team ' s turnovers distingguish a lot with opponents.

在强对抗的攻击性防守下中国队不能解决好进攻的问题是世锦赛失利的最主要的原因之一；中国队的快攻次数与对手的差异具高度显着性，成功次数的差异具显着性，得分的差异具高度显着性，断球后发动快攻的差异具显着性；得分主要集中在接球得分、单打得分、和罚球得分这三个方面，得分手段单一而且集中；战术进攻与对手呈差异有高度显著性，作为主动进攻的罚球和争夺篮板球都比对手低；抢断与对手的的差异具显着性，进攻成功率与对手的有一定的差距，进攻效率的差距更大；2分球的投篮次数与对手的具有高度显著性差异，命中率比对手稍高一点，3分球投篮次数相当，命中率具有显著性差异；中国队的前场篮板球与对手相比具有显著性差异，但是二次进攻得分却比对手略高一点；中国队与对手的助攻相比有显著性差异；中国队的抢断与对手相比具有高度显著性差异；中国队的失误与对手相比具有高度显著性差异。

通过对甲醇气相脱水制二甲醚反应特点的研究，提出了使用拟等温管式反应器的概念；并用二维数学模型进行了数学模拟；在该模型上进行了操作条件对催化床温度分布影响的模拟研究，从而提出了该反应器的结构尺寸，为甲醇气相脱水制二甲醚的大型化开发提供了设计依据。

The age was around 25 to 45 years. Jianshi on Pericardium Meridian of Hand Jueyin and Weizhong on Bladder Meridian of Foot Taiyang was acupunctured."Active"/"silent" time of points were projected with Ziwuliuzhu Najia method. Acupuncture was done at the points "active"/"silent" respectively. The changes of NO content at the body points were detected. The difference of acupuncture in different time at the body points was compared.
