In particular, we compute Hochschild homology and cohomology groups of infinitedimensional path algebras and some of their quotient algebras, and we prove that for a general monomial algebra (not necessary finite-dimensional), all Hochschild cohomology groups of positive degrees vanish if and only if its Gabriel quiver is a finite tree.

特别地，我们计算了无限维路代数以及某些商代数的Hochschild同调群和上同调群，而且给出了一般单项代数的各正次Hochschild上同调群为零的充分必要条件，即它的Gabriel箭图是有限树。

The IIA property might not be satisfied in human decision-making of realistic complexity because the scalar preference ranking is effectively derived from the weighting—not usually explicit—of a vector of attributes (one book dealing with the Arrow theorem invites the reader to consider the related problem of creating a scalar measure for the track and field decathlon event—eg how does one make scoring 600 points in the discus event "commensurable" with scoring 600 points in the 1500 m race) and this scalar ranking can depend sensitively on the weighting of different attributes, with the tacit weighting itself affected by the context and contrast created by apparently "irrelevant" choices.

该协会的财产可能不能满足人类的决策现实的复杂性，因为标偏好排名实际上是来自加权，通常没有明确的载体的属性（一本书处理的箭定理请读者考虑有关问题创造一个标措施，田径十项全能比赛，例如如何使一个得分600分，铁饼事件"公"与得分600分， 1500米比赛）和本量排名可以依靠敏锐的加权不同的属性，与默契加权本身受影响的范围和所创造的对比显然是"无关"的选择。

There is a small action range in archery.Simple methods and analysis is inadequate,so the author,on the basis of testing the archery athletes in national team with the Qualisisy infrared photoelectric testing system,Footscan sole pressure testing system,Noraxon myoelectricity remote testing system, etc,analyzes comprehensively the action technique of the athletes in national team from the posture,body motion characteristics,body posture equilibrium and stability,distribution of centre sole pressure, myoelectricity characteristics,etc,with the methods of relative software and data statistics.The conclusions and the suggestions are as follows:Conclusion:Firstly,the communality of posture angle,muscle strength,the activation order of main muscle during raising the bow, raising the bow and the timing of the raising could be used as the evaluation index of technique action in archery;Secondly,the length of the time needed in the different periods couldn\'t be used as technique evaluation index since it has no relation with the result.But the time of raising and pulling back the row is relatively fixed,and the time has a positive relation with the archery achievement of the national team in China.Thirdly,the central index of the sole pressure could be used as the reference criterion of selecting athletes and forecasting achievement.During playing archery,the interrelation between the central index of the sole pressure and the achievement is different individually and in different periods.Fourthly,there is low stability of the archery athletes in the front and back direction during the action, caused by the athletes\' posture disequilibrium of dorsal abdominal muscle and non-professional sport shoes..Fifthly,kinematics and electromyography shows that the people on archery in China haven\'t taken the raising and pulling back the row seriously.

射箭的肢体动作幅度小，简单的手段和分析不能满足其需要，笔者结合各种运动生物力学仪器优点及射箭项目的特性，选用Qualisisy红外光点测试系统、Footscan足底压力测试系统、Noraxon肌电遥测系统等对国家队射箭队运动员进行多方位的测试，运用相关软件及数理统计方法，对运动员的射箭动作技术，从射箭动作的姿态构架、肢体运动特点，身体姿态平衡稳定性、足底压力中心分布、肌电特性等进行全面分析，结论及建议如下：结论：第一，姿态角、肌肉用力激活程度、举弓阶段主要用力肌肉激活顺序、举弓、开弓时间等的一致性可作为射箭技术动作评价指标；第二，各动作阶段所用时间的长短不能作为技术评价指标，但举、开弓的时间相对较固定，开举弓时间比与中国国家队射箭成绩正弱相关达到显著性；第三，闭眼状态下足底压力中心单位面积轨迹长与144支箭最好成绩正相关达到显著性，可作为身体素质、选材及成绩预测的参考依据；实射时身体平衡的足底压力中心指标与成绩的相关程度具有个体性差异、阶段性差异；第四，射箭运动员实射时身体在前后方向上的稳定性较差，这与运动员的站立姿态、腹背肌力量的不匹配以及射箭没有专业运动鞋有关；第五，运动学及肌电学都表明中国射箭训练对举弓、开弓阶段的重视不够，背部肌肉用力特征不明显，撒放技术合理性不高。

Based on the principle of compound pendulum ,the measurement method and corresponding equipment for the centroidal deviation and the rotary inertia of rocket projectile were described.

基于复摆原理，阐述了箭弹的质偏和转动惯量的测量方法及装置，推导出了质偏和转动惯量的计算公式。

After doing some more research, confab'ing with some pro shamans, and reading lots of forum posts, we decided this was probably a sufficient niche for CL and trying to push it into a purely AE role would mean a loss of fun for some shamans.

在作出更多研究，论坛的帖子以及与一些资深萨满交换意见之后，我们认为这么改动(将闪电箭单体伤害降低但作用更多目标的改动)将会使得闪电链的作用变得过于单一以至于对不少萨满来说少了不少乐趣。

The son of Priam hit the breastplate of Menelaus's corslet, but the arrow glanced from off it.

正如在一大片打谷场上，黑皮的豆粒和鹰嘴豆儿高弹出宽面的锹铲，在呼吹的劲风中，随着杨荚者有力的抛甩，致命的羽箭弹离光荣的墨奈劳斯的胸甲，蹦出老远，硬是被顶了回去。

Here Love his golden shafts imploies, here lights His constant Lamp, and waves his purple wings, Reigns here and revels; not in the bought smile [ 765 ] Of Harlots, loveless, joyless, unindeard, Casual fruition, nor in Court Amours Mixt Dance, or wanton Mask, or Midnight Bal, Or Serenate, which the starv'd Lover sings To his proud fair, best quitted with disdain.

在这里，小爱神射出黄金的箭，点着长夜明灯，挥动紫艳的翅膀，尽欢地统治着这里；不是从娼妓买来的浅笑，或无爱无欢无情谊，一时的作乐；也不是宫廷艳事，男女私混，或淫荡的假面剧，半夜的舞会，或忍冻的情夫，对他高傲的美人儿唱的小夜曲，这些都是为人所唾弃的。

When aiming for a distant target, the crossbowman can estimate using the Wang Shan on how high he should elevate his crossbow. The crossbow bolts fired would thus follow a parabolic path and hit the enemies accurately.

当瞄准远处的目标时，射手参照望山估算弩抬高的角度，弩箭沿抛物线轨迹就可以准确命中敌人。

There lies the dead man, in the black cloak wrought with silver; the crozier in the powerless hand that was once so mighty.

3丹麦西海岸海难很多，那里的渔民使用一种能发射带着绳索的箭一般的铁器的机械装置。

But Menelaus reassured him and said,"Take heart, and do not alarm the people; the arrow has not struck me in a mortal part, for my outer belt of burnished metal first stayed it, and under this my cuirass and the belt of mail which the bronze-smiths made me."

听罢这番话，棕发的墨奈劳斯宽慰道："勇敢些，不要吓坏了会战此地的阿开亚人。犀利的箭镞没有击中要害，闪亮的腰带挫去了它的锋芒，底下的束围和铜匠精心制作的腹甲挡住了它的冲力。"

What would he tell Judith and the children?
