其測量法年夫優于傳統的手工方法：該裝置是一種低成本，高精度的單擺實驗裝置。 -
The results of studying show that time dilation effect in horizontal motion of compound pendulum is a result of the change in mechanism of dynamics such as acceleration of gravity, such in vertical motion of compound pendulum is due to both the change in mechanism of dynamics and the change in mechanism of kinematics
結果表明，復擺鐘整體沿水平方向運動的鐘慢效應是因為動力學機制發生了變化；而沿垂直方向運動的鐘慢效應，既與動力學機制的變化有關，也與運動學機制的變化有關。 -
The first part makes a detailed exposition on " problem - inquiry " model in the aspects of historical origins, connotation, theoretical basis, operation programme, evaluation system and implementation conditions etc. in accordance with the different characteristics and requests of theoretical, experimental, exercises lessons, the second part illustrates how carry out " problem - inquiry " model respectively using the motion of level projectile, determine acceleration of gravity with single pendulum, the motion question of pursuit and meeting as living examples
第二部分（第二章）針對理論課、實驗課、習題課等不同課型的具體特點及要求，分別以《平拋物體的運動》 、 《用單擺測定重力加速度》 、 《追及與相遇問題》為實例，論述了在理論課、實驗課、習題課教學中，如何實施「問題一探究」式教學模式。 -
Based on variable zmp and dynamics of 3 - d inverted pendulum, we educed the cog ( center of gravity ) ’ s trajectory equation of the robot in the single - support phase and transition of locomotion phase. and we used third - order spline function to ensure the acceleration continuity of the robot ’ s cog in the double - support phase. thereby, the smooth trajectory of cog was gained by planning
由基於可變zmp和三維倒立擺的動力學原理，推導出了單腳支撐期內和步行方式轉換期間機器人的質心運動軌跡方程;並採用三次樣條曲線來保證機器人在雙腳支撐期質心加速度的連續性，從而由規劃得到了光滑的質心運動軌跡。 -
As the legged system has a similar dynamics to that of three - dimensional inverted pendulum mode, whose supporting point is equivalently located at the zmp, what is more, there is dynamical relationship between the zero moment point ( zmp ) and the center of gravity ( cog ), so this paper proposed the method that controls the cog of the whole humanoid body system in real - time through the 3 - d inverted pendulum based on variable zmp : first, the irregular terrain analyzed and described, the author proposed an usual obstacles - spanning method, based on the position and the shape of obstacles, the author programmed the smooth trajectory of anklebones
由於機器人的腿系統和三維倒立擺模型有著相似的動力學特徵，模型的支撐點就是機器人的零力矩點zmp ，另外零力矩點zmp和重心cog之間存在著動態關系，本文採用基於可變zmp的三維倒立擺動力學原理來對類人猿機器人進行質心軌跡生成。首先，通過對復雜地況進行分類統一描述，提出了一套通用的越障軌跡規劃方法，結合復雜地況下障礙的位置和形狀，規劃了機器人連續的踝關節軌跡。 -
This short - arc coupled with the low pendulum effect achieved by pivoting the disc through a point near its center of gravity assures rapid closure
繞軸旋轉的閥瓣的重力中心距軸心較短，因此這種短弧的鐘擺效應也比較小，從而確保能夠迅速關閉。
