   牛頓定律，動量的概念，能量，角動量，剛體運動，以及非慣性系。
2. According to the principle of the rigid body motioning , the theory composed the bending by the two principal axis and the rotation around the shear center to a rotation around a new point
   此理論把構(gòu)件繞兩軸的彎曲平動和繞剪心的翹曲轉(zhuǎn)動依剛體轉(zhuǎn)動原理合成為繞新一點的轉(zhuǎn)動，從而使桿件的空間穩(wěn)定分析更加直觀、簡便。
3. We give a brief but systematic introduction to differentiable geometry and lie group , lie algebra . rigid body motion expressed with the notations from these theories is also introduced . they are the theoretical bases of the subsequent research contents
   2 、基本成體系地介紹了微分幾何中的李群、李代數(shù)理論，并分析其表達剛體運動的作用，為本文的研究打下基礎(chǔ)。
4. On the one hand , the linear interpolation in ( x , y ) plane makes it easy to separate the three - dimensional null subspace corresponding to rigid body motions , hence what is left to do is just to compute the inverse of a symmetric definite submatrix numerically . in this way the numerical difficulty in computing general inverse can be avoided
   在物理坐標系中的線性插值函數(shù)便于將三個剛體模式分離出來，從而只需計算對稱正定子陣的逆，避免了求廣義逆的數(shù)值困難；在參考坐標系中的高階插值函數(shù)則可保持原平面彈性單元的列式方式。
