It ' s possible . short iron stick and mace are the weapon carried by buddha and god . it ' s more possible that there ' s not sword but mace on the wrist of the god in the 2nd fresco . suppose that sword is edge tool and should not be on the wrist as usual , while mace is converse . it looks like four arrises mace more or less 有此可能,鞭锏历来是佛道神将所持的兵器,第二张壁画神将腕上悬挂的更可能是锏而非剑,试想剑乃利器,照常理是不应挂腕的;而锏乃钝刃打击器,挂腕使用道很合常理,从收藏的明代以前四棱锏实物来看,还真有几分相似的
Nobody came near them , and their movements showed a mechanical regularity ; their forms standing enshrouded in hessian wroppers - sleeved brown pinafores , tied behind to the bottom , to keep their gowns from blowing about - scant skirts revealing boots that reached high up the ankles , and yellow sheepskin gloves with gauntlets . the pensive character which the curtained hood lent to their bent heads would have reminded the observer of some early italian conception of the two marys 没有人走近她们她们的动作像机械一样地一致她们站在那儿，身上裹着麻布罩衫这是一种带袖子的黄色围裙，从背后一直扣到下摆，免得让风吹来吹去穿着短裙，短裙下面是脚上穿的靴子，靴子的高度到达了脚踝以上，手上戴的是带有护腕的羊皮手套。
This article is to design a skew - rpyr mechanical wrist not only with comparatively high workspace and dexterity but also the capability of circumventing the mechanism singular position effectively while operation . the dynamics analysis and calculation will become the basis of practical control . a short review of the development in wrist design is introduced in the paper , and the development of the idea of the skew - rpyr wrist put forward is necessary 斜四关节手腕( skew - pryr )具有较大运动空间和较高的灵活度,通过运动学的分析和优化使该手腕具备在运动中有效回避机构奇异和手腕关节运动范围极限的能力,并且用拉格朗日法对手腕的动力学的分析和计算为以后实现控制作了准备。
