For small displacement u , the oscillator is a duffing - type cubic non - linear oscillator , while for large displacement u , the oscillator approximates to a linear harmonic oscillator 所谓达芬谐波振子是指当位移远小于1时,系统可化为三次非线性振子,而当位移远大于1时,该系统则化为线性谐波振子。
The author has calculated the spontaneous radiate probabilities , the linear oscillator strengths , branching ratio of tm3 + iones by judd - oflet theory . according to the j - o calculated data , the transition 1g4 ? 3h6 was stronger than the transition 1g4 ? 3h4 . it was agreement with the emission spectra 3 )对tbzre玻璃,用j ? o理论计算了各光谱参数,从1g4能级的跃迁分支比从理论上得出480nm波长的光相对650nm波长的光强,这与发射光谱图是相符合的。
In order to prove the existence of the periodic boucing solutions , firstly we will introduce a new coordinate transformation , transform the system from right half plane to the whole plane . and give the relation of the eigenvalues of hill ' s equation and the rotation numbers , using this approach and pioncar - birkhoff twist theorem , we proved the existence of the periodic bouncing solutions for asymptotical linear oscillator 对于周期解的存在性证明,我们引进新的坐标变换把右半平面上的碰撞问题转化到整个平面上,给出旋转数与hill方程的特征值的关系,并以此来度量渐近线性振子,再应用pioncar - birkhoff扭转定理得到周期碰撞解的存在性。
