The grads projection algorithm of redundant robot multi optimizing capability function's proportion factor is deduced. The issues of apery arm robot singularity and joint self-movement are researched. The simulation experiment result of apery arm joint self-movement and line movement is presented.

因为七自由度拟人手臂机器人的建模比较困难，采用了在等效模型下求解其运动学逆解的方法，给出了原机器人机构关节角与等效模型关节角之间的转换关系；提出了一种适于数值计算的有效的求解有关节偏置的冗余度机器人Jacobian的算法，并在此基础上推导了冗余度机器人多优化性能指标函数的均衡比例因子梯度投影算法；研究了拟人手臂机器人的奇异问题和关节自运动问题；给出了拟人手臂进行关节自运动和进行直线轨迹跟踪的仿真实验结果。

Based on the tensor expression for the Breit-Pauli Hamiltonian,and with the aid of irreducible tensor theory,the theory of relativistic corrections to the non-relativistic energies of many-electron atoms has been generalized to the case in which Racah wave functions are the linear combinations of multi-Slater wave functions,analytic formulism for calculating the relativistic corrections,which include mass correction,one-and two-body Darwin correction and spin-spin contact interaction,has been derived,all th...

以Breit-Pauli哈密顿的球张量形式为基础，借助不可约张量理论，将多电子原子能量的相对论修正理论拓展到了原子的拉卡波函数为多个Slater基函数的线性组合的情形，导出了此情形下多电子原子能量相对论修正(包括相对论质量修正项、单体和双体达尔文修正项、自旋-自旋接触相互作用项)的解析表达式，完成了所有角向积分和自旋求和计算。

The main components of the lathe are the headstock and tailstock at the oppoaite ends of a bed,and a tool-post between them which holds the cutting tool.the tool-post stands on a cross-side which enblesit to move sidewards across the saddle or carriage as well as along it,depending on the kind of job it is doing.the ordinary centre lathe can accommodat only one tool at at time on tool-post,but a turret lathe is capable of holding five or more tools on the revolving tueeet.

刀架位于一个纵面板上，小拖板使刀架能够根据加工操作的不同作纵向移动；同时又随大拖板作横向移动。普通顶尖车床只能在刀架上夹持一件刃具，但六角车床可以在其旋转的六角刀架上夹持五件或更多的刃具。车床的床身必须很牢固结实以避免在受力的时候弯曲和变形。请提问的同学最好参观一下工厂的金属切削/机加工车间。那里有车床，还有其他种类的金属切削机床。

Comclusion: transpetrous presigmoid retrolabrinth approach was rational approach for surgery on petroclivus and -4- CPA; it抯 important for accomplish the surgery to study and master the anatomy and variance of this approach; there was relative anatomical relationship among those structure on posterior of petrous bone; AAMP was the extracranial mark of inflexion of TS and SS; LAM and PSC were obvious bone marks for operation; we can confirm the abraded range of petrous bone lean upon LAM and/or GSS beside abrading step by step as literature, and it抯 unnecessary and unrational to emphasize to show PSC if the surgical space was enough; preceding sigmoid sinus and high jugular bulb often appeared at right and would bring disadvantage effect; interspace ,between CN V and CNVII or CNVII and CNJXI, were available to reach clivus and manage the mass on the range.

经SS前迷路后入路是处理岩斜坡区、桥小脑角区病变理想的手术入路；研究和熟悉手术入路中的解剖结构及部分变异对指导手术十分必要；岩骨内测面的骨性结构之间有着相对稳定的空间关系；顶乳缝前角是SS和TS转接处在颅外的标志；IAM和PSC等结构可以作为手术中的重要骨性标志；以PSC确定岩骨的磨除范围是较安全和可靠的，但亦可以结合影像检查，以内耳道和乙状窦前缘为基点判定切除范围，如果操作空间足够，过分强调磨出半规管是不适当的；右侧GSS的宽度和深度较对侧大，SS前置和颈静脉球高位较对侧多见，这些都对右侧入路有不利的影响，但仍可以进行手术操作；三叉神经和面神经间隙及面l 神经和舌咽神经间隙方便到达斜坡并处理病变。l

The morphologic change of muscle fibers: At the early stage of denervation, the area of cross sections decreased, some muscle fibers turned into angular fibers, nuclei congregated around the center of the fibers. After 8 weeks of denervation, atrophic and hypertrophic fibers coexist. Collagen increases under the endomysium and between the fibers.

肌纤维的组织形态学变化：面部肌肉失神经支配早期，肌纤维的横截面面积变小，出现角状纤维，肌细胞核聚集，细胞核从肌纤维边缘移至肌纤维中央附近；失神经支配后期，肿胀与萎缩的肌纤维并存，肿胀的肌纤维的横截面成倍大于正常的肌纤维，而萎缩的肌纤维的横截面则成倍小于正常的肌纤维；有大量的角纤维存在，肌纤维之间有较多的结缔组织增生。

The anteroposterior projectionof the foot, utilized to examine the foot disease in the past was referred as to the freely-stressed method. However, most of the patients on suspicion of Hallux Valgus get pains while standing with weight-bearing. Additionally, the patients' real conditions can not be diagnosed without standing. it is helpful for us to apply both the foot weight-bearing and the foot non weight-bearing so as to probe the individual difference between the HVA and the IMA 1(superscript * intermetatarsal angle and further to provide the informative resources concerning the assessment of performing surgery operation. The study include 40 patients who we having Hallux Valgus of different degree, The findings have revealed the significant difference among 40 patients after the method-weight-bearing AP of the foot projection given.

过去一般常用诊断足部疾病的足部摄影(anteroposterior projection of the foot； AP projection of the foot)是指未施加压於病人足部的拍摄方法，然而多大脚趾外翻的病患常於站负重时感觉疼痛舒服，而未负重摄影却无法呈现出病人站时的真实态，因此我们用足部前后位负重摄影(weight-bearing AP projection of the foot)与足部未负重摄影(non weight-bearing AP projection of the foot)的影像比较其大脚趾外翻角(Hallux valgus angle， HVA)及第一跖骨间的角1(上标 st intermetatarsal angle， IMA的差，进而提供外科手术的估评。

Little Bighorn Battlefield National Monument memorizes one of the last armed efforts of the Northern Plains Indians to preserve their ancestral way of life. Here in the valley of the Little Bighorn River on two hot June days in 1876, more than 260 soldiers and attached personnel of the US Army met defeat and death at the hands of several thousands Lakota and Cheyenne warriors. Among the dead were Lt.
