There is mutual contradiction between direction estimation of user's signal and power allocation among all users in the beamforming algorithm. A twice game beamforming algorithm based on game theory is proposed to deal with it. Beamforming game algorithm mathematics model is constructed. During the first game, direction of signal and power allocation are mapped the game theory as "player", which are modeled as the problem of maximin function and obtain direction estimation first. Then during the second game, power allocations of different users are described as a multi-user game. Power updated algorithm is designed. The existence and uniqueness of the Nash equilibrium in the twice game beamforming algorithm based on game theory are proved by mathematics derivation.

摘要针对波束成形算法中，用户的信号方向估计值和用户之间的功率分配存在着相互矛盾，本文提出了一种基于博弈论的二次博弈波束成形算法，构建了波束成形博弈算法数学模型，首先在第一次博弈的时候，将波束成形算法中的信号方向和功率分配映射为博弈论数学模型中的"局中人"，将其建模为函数的极大极小值求解问题，先求解出信号方向；然后在第二次博弈的时候，将不同用户的功率分配过程描述为一个多用户的博弈过程，设计了功率分配更新算法，通过数学推导论证了纳什平衡点的存在性和唯一性。

In this study the incidence of acute mountain sickness was 24% for people taking 125 mg twice daily, 21% for people taking 325 mg twice daily, and 51% for people taking placebo.9

Methods A randomized,double-blind,double-simulant,parallel-controlled,multicentric study was carried out in 207 patients with bladder overactivity,patients received either tolterodine (2 mg twice daily)or oxybutynin (5 mg twice daily).

采用随机、双盲、双模拟、平行对照的方法对207例膀胱过度活动症患者进行托特罗定与奥昔布宁的对比研究，服药方法每日2次，每次托特罗定2mg或奥昔布宁5mg。

In this double-blind, placebo-controlled, parallel-group, multicenter study, 656 patients with type 2 diabetes requiring insulin treatment were randomized to receive additional preprandial subcutaneous injections of either placebo or pramlintide, 60 g three times daily, 90 g twice daily, or 120 g twice daily.

每天额外接受2次120 μg pramlintide注射的患者，其糖化血色素（HbA1c）从第26周的-0.68%持续降到第52周的-0.62%，效果明显大於安慰剂（P 。05），糖化血色素（HbA1c）降到以下8%者，120 μg治疗组占46%，安慰剂则仅占28%（P 。05）；第52周时，120 μg治疗组的患者也比安慰剂患者获得较好的体重控制（体重改变幅度：-1.4 kg vs。

According to the J.D. Power Initial Quality Study－which measures product quality using a metric called "PP100," or problems per 100 vehicles－China's industry average PP100 rating stands at 231, or almost twice the U.S. average of 124. And among domestic Chinese brands, quality problems are almost twice as frequent as in locally built international brands （an average of 368 PP100 for domestic brands, compared with 189 for international brands）.

J.D。 Power调研公司《新车质量调查》（依据被称为PP100的测评标准，即以每百辆车的问题数量为测评汽车质量标准）的结果显示，中国汽车业的PP100平均高达231，几乎相当于美国汽车业平均值124的两倍；而中国自主品牌汽车的故障发生率，也几乎是同样产自中国的外资品牌汽车的两倍。

Head turned the ball over twice after freaking timoeouts,Then he doesn't freakin box ray allen out twice

The conclusion was drawn by the synthesis of molecular sieve: after mixed soluble glass and aluminium sulfate with proper proportion under room temperature, it was stirred stormily to react. And then we mixed with potassium hydroxide solution after filtrating. At last, the molecular sieves of potassium type was synthesized after the mixture reacted in the oven or autoclave for 24 hours. The molecular sieve was remodeled more than twice with ammonium chloride solution that the concentration was 3mol/L and then remodeled twice with the saturated sodium chloride solution. Finally the molecular sieve was changed into the sodium type. It was named W zeolite.

通过对分子筛的合成得到：以泡花碱、硫酸铝为原料，以硅铝比按一定比例于室温下将二者混合，激烈搅拌，抽滤后与氢氧化钾溶液混合放于烘箱或高压釜中高温晶化24小时，晶化后的分子筛为钾型，先后用3mol/L氯化铵溶液和饱和食盐水各对其改型两次以上，最后改为钠型，可制得W型沸石分子筛。
