s-d curve
解釋
強度-持續時間曲線,強度-間期曲線-
Second, the author introduced a new stability region, and programmed a trajectory of variable zmp, which was defined as a cosine curve ; the author also designed a cog - compensated method to keep the cog ’ s height ; based on dynamics of 3 - d inverted pendulum, the author educed the cog ’ s trajectory equation of the robot in the three - leg - support phase, and used third - order splint function to ensure the acceleration continuity of the robot ’ s cog in the four - leg - support phase. at last, walking patterns of the corresponding gait are generated through programmer design
然後，提出了一種新的支撐區域選取方法，採用了按餘弦規律變化的zmp運動軌跡;為了維持機器人行走時重心高度不變，採用了一套有效的質心高度保持方法;基於三維倒立擺模型，推導了機器人三腳支撐期質心運動軌跡方程;採用三次樣條曲線插值規劃了四足支撐期加速度連續的質心運動軌跡。 -
Firstly, fourier descriptor used to describe the object ' s shape is introduced to the extraction of feature of apple ' s shape. the boundary of apple is an obturated curve, distance between boundary point and centroid r ( k ) " is used as a function to express the 2 - d boundary in spatial domain. the fourier transform coefficients of the discrete sequences f ( h ) are spectrum values in frequency domain, and they compose feature parameters of shape
首次將圖像分析理論中對形狀的傅立葉描述方法引入到對蘋果形狀的特徵提取中，果實邊界是一條封閉曲線，用邊界點到形心之間的距離長度r （ l ）作為空域中對二維曲線的表達函數，離散的函數值序列r （ k ） ~ l的離散傅立葉變換系數f （ h ）就是頻域中得到的頻譜值，可作為形狀的特徵參數。 -
In this thesis, the inviting & biding mechanism is analyzed and the feasibility and function of its operation is also conducted. under the framework of the analysis of the supply and demand of engineering insurance, the concept of security and economy is brought up : the district characteristics of the equilibrium on s / ' d curve is studied of large - scale engineering insurance. also, the optimal principle of insurance arrangement is brought up
論文對招投標機制運用於工程保險的承保環節進行了分析，闡述其運作的可行性和意義；通過對工程保險供給與需求的研究，提出了保險人和被保險人承保的安全性和經濟性的概念，分析了大型工程保險供需曲線均衡點的區域特徵，由此得出了保險方案的最優化原則以及在該原則指導下經保險雙方動態選擇后的最優保險方案。
