He personally experiment to determine the law of free-fall and found that: The object of the law of inertia, a reasonable law, such as when the pendulum vibration, the law of Motion put forward a campaigns of the principle of relativity, but also on the speed, acceleration and so on kinematics The basic concept of making a strict definition.

Firstly, the function sinx that appears in the simple pendulum equation is replaced with a polynomial of degree 3 using Maclaurin series expansion and Chebyshev polynomial approximation. Subsequently, the resulting equation which is a Duffing type equation is approximately solved with combing Newton's method and the harmonic balance method.

首先，利用Maclaurin展开和Chebyshev多项式加速技术将单摆振动方程中的正弦型恢复力用三次多项式近似代替，得到一个Duffing型方程；然后，将牛顿法与谐波平衡法结合起来建立Duffing方程的解析逼近周期及周期解，从而给出单摆振动的解析逼近解。
