目的:分析竞技健美操运动员落地动作的生物力学特征,比较优势侧和非优势侧生物力学指标的偏侧性,探究影响落地稳定性的关键偏侧性因素。方法:以26名高校女性健美操运动员为研究对象,同步采集40 cm高台垂直双脚落地动作中的下肢运动学和动力学数据,比较优势侧和非优势侧的触地时刻关节角度、关节活动度(ROM)、地面反作用力(GRF)、负载率、压力中心(COP)位移和包络面积的差异,计算对称指数(代表偏侧性),并采用多元逐步回归方法分析指标偏侧性和COP包络面积的关系。结果:与非优势侧相比,优势侧在触地时刻具有更大的膝外旋和髋外展角(P<0.05),在落地过程中具有较大的踝屈伸、髋屈伸、髋内收-外展及较小的踝旋转ROM(P<0.05);优势侧的伸膝力矩峰值大于非优势侧(P<0.01);垂直方向负载率和伸膝力矩峰值的对称指数与COP包络面积呈显著正相关(P<0.05);垂直方向负载率、伸膝力矩峰值和膝关节旋转角度的对称指数可以解释COP包络面积差异的83.6%。结论:竞技健美操运动员落地动作存在肢体间的偏侧性,垂直方向负载率和伸膝力矩峰值的偏侧性越大,则落地稳定性越差。此外,垂直方向负载率、伸膝力矩峰值和膝关节旋转角度的对称指数可以作为落地稳定性的预测因子。

A reuse fabrication module using micro electroetching as a precision machining process with a new design of a slant-form tool to remove the defective indium-tin-oxide （ITO） nanostructure from the optical polyethyleneterephthalate （PET） surfaces of digital paper display is presented in current studies. The low yield of ITO thin film deposition is an important factor in optoelectronic semiconductor production. The adopted precision reuse process requires only a short period of time to remove the ITO nanostructure easily and cleanly, which is based on technical and economical considerations and is highly efficient. In the current experiment, a large inclined angle of the cathode and a small end radius of the anode take less time for the same amount of ITO removal. A higher feed rate of the optical PET diaphragm combines with enough electric power to drive fast micro electroetching. A small rotational diameter of the anode accompanied by a small width of the cathode corresponds to a higher removal rate for the ITO nanostructure. A pulsed direct current can improve the effect of dreg discharge and is advantageous to couple this current with the fast feed rate of the workpiece. This improvement is associated with an increase in current rating. High rotational speed of the slant-form tool can improve the effect of dregs discharge and is advantageous to associate with the fast feed rate of the workpiece （optical PET diaphragm）.

Color filters are produced using semiconductor production techniques although problems with low yield remain to be addressed. This study presents a new means of selective removal using excimer irradiation, chemical etching, or electrochemical machining on the fifth generation TFT LCDs. The selective removal of microstructure layers from the color filter surface of an optoelectronic flat panel display, as well as complete removal of the ITO thin-films, RGB layer, or resin black matrix (BM) layer from the substrate is possible. Individual defective film layers can be removed, or all films down to the Cr layer or bare glass can be completely eliminated. Experimental results demonstrate that defective ITO thin-films, RGB layers, or the resin BM layer can now be recycled with a great precision. When the ITO or RGB layer proves difficult to remove, excimer light can be used to help with removal. During this recycling process, the use of 225 nm excimer irradiation before chemical etching, or electrochemical machining, makes removal of stubborn film residues easy, effectively improving the quality of recycled color filters and reducing fabrication cost.

A new effective tool design of three-rank form of electroremoval was present using a precision recycle system offering faster performance in removing the indium-tin-oxide(ITO) thin-films on color filter surface of displays. Higher electric power is not required since the three-rank form tool is adopted as a feeding mode to reduce the response area. The low yield of ITO persists throughout the entire semiconductor production process. By establishing a recycle process of ultra-precise removal of the thin-film nanostructure, defective products in the optoelectronic semiconductors industry can be effectively recycled, decreasing both production costs and pollution. A 5th generation TFT-LCD was used. The design features of the removal processes for the thin-films and the tool design of three-rank form were of major interest. For the precision removal processes, a pulsed current can improve the effect of dreg discharge and contributes to the achievement of a fast workpiece (displays' color filter) feed rate, but raises the current rating. High flow velocity of the electrolyte with a high rotational speed of the tool electrodes elevates the ITO removal effect. A displays' color filter with a fast feed rate is combined with enough electric power to provide highly effective removal. A small thickness of the rank and a small arc angle of the negative-electrode correspond to a higher removal rate for ITO-film. An effective three-rank form negative-electrode provides larger discharge mobility and better removal effect. It only needs a short period of time to remove the ITO easily and cleanly.

根据《西藏王臣记》等史书记载,帕竹政权的第一任第悉大司徒绛曲坚赞为了稳固政权,促进发展,采取了减轻差税、改定法律、在各冲要地点兴建以内邬栋孜为首的城堡(宗)、设立宗谿等一系列制度。关于他所修建的城堡(宗),后人习惯称之为“大司徒的十三大宗”,但相关文献资料中几乎找不到“十三大宗”这样确切数字的表述。因此,对所谓“大司徒的十三大宗”的说法有待进一步考证,并且对于一些史书及论文中出现的琼杰宗、白朗伦珠孜宗、江噶尔达孜宗等类属于“大司徒的十三大宗”的说法更有待于进一步商榷。
