In the first part, study 1 was designed to investigate the development of the science inquiry ability in the group of the primary and secondary School student, and how the task difficulty affects science inquiry. We used the self-directed, computer simulated inquiry task, namely pendulum and string task It required the subjects to find the factors that affected the swing frequency of the pendulum and the level of stretch of the string. To evaluate the ability of science inquiry, we analyzed subjects'experiment-design strategies, evidence-evaluation strategies, and results of inference.

实证研究分两部分，第一部分即研究一，采用计算机模拟的自我指导实验探究任务，任务内容为单摆实验和弹簧实验，要求被试自主探究影响单摆摆动频率和弹簧伸拉长度的因素，并以科学探究的全过程为研究对象，以被试探究中的实验设计策略水平、证据评价策略水平以及正确推论结果作为衡量科学探究的指标，系统探讨了小学高年级和初中学生科学探究的特点。

The gravitational vehicle driven gravitationally has wheel pendulum, eccentric pendulum and other structure for best utilization of gravity force.

重力车充分利用重力作动力，车体与车轮摆连接，偏心摆等结构可利用更多重力。

The controller for the inverted pendulum-cart is then designed by using this pole placement method. The design is rather intuitive and simple. The next design for the inverted pendulum is to use two-block and four-block H〓 optimal synthesis methods. The results are then analyzed from the viewpoints of fragility and robustness.

论文又采用H〓的两块问题和四块问题分别对倒立摆系统进行系统性的优化设计，并从脆弱性和鲁棒性两个方面对设计结果进行了分析，指出倒立摆H〓优化设计的主要问题还是没有鲁棒性。

This thesis mainly calculate and analyze the effect of gravitational gradient based on the torsion pendulum, the result showed that for the modulated torsion pendulum, the torque caused by the gravitational gradient reached to 10~(-12)Nm, while the dissymmetry of round gravitational field can also affect the experiment.

本文主要计算和分析引力梯度效应对弱等效原理实验的影响，结果发现对于调制的扭秤，由于系统的不对称所引起的引力梯度效应达到了10~(-12)Nm，而周围引力场的不对称同样也会对实验产生不同程度的影响。

The methods testing the WEP usually are torsion pendulum and free falling, the latter one is limited by the height of experiment, so the sensitivity of this method can't be improved, thus nowadays the torsion pendulum is mostly used in high sensitivity experiment.

检验弱等效原理的方法多为扭秤方案和自由落体方案，自由落体法由于受到实验高度的限制，使得在地球上的实验精度无法得到进一步提高，因此现在高精度的地面实验大都采用扭秤方案。
