According to the theory of harmonic motion,the cycle of the simple pendulum is analyzed by infinitesimal and experiment respectively,the formulation and the function curve of the cycle T altered with the location of the liquid surface are obtained,the law of pendulum cycle changed with the pendulum ball's mass reduced is showed more accurately and obviously.

根据谐振动理论，分别用微积分推导和实验测定的方法，分析了一类常见的关于摆球质量减少的单摆周期问题，得到周期T随液面位置h变化的函数关系式，以及周期T随液面h变化的曲线，较精确和直观地展示了因摆球质量减少而导致周期变化的规律。

Mainly consists of two aspects, one is made from an inverted pendulum control of the initial perspective through direct adaptive fuzzy control methods to restore stability at Liandugu; the other is an inverted pendulum control from the initial point begun tracking a sine curve, Even inverted pendulum angle according to the requirements of the sinusoidal changes.

主要分两个方面，一方面是使倒立摆从一个可控制的初始角度开始通过直接自适应模糊控制的方法使其重新稳定在零度角；另一方面是使倒立摆从一个可控制的初始角度开始使其跟踪一个正弦曲线，即使倒立摆的角度按所要求的正弦变化。

The influence of the excursion of the mass center of the torsional vibrating system of the three-string pendulum on the measurement of the moment of inertia is analyzed. A criterion for the mass center of the torsional vibrating system to be in alignment with the central axis of the three-string pendulum and a practical method to measure the moment of inertia of a body about a noncentral axis of mass using the three-string pendulum are proposed.
