Studying at Jen-ai school is her leaning's another step and it is also the cradle that arouses her talent of writing. In order to improve her own ability, she tries every hard even she is on a wheel chair. She used her only-left hearing ability to listen to class carefully.

偏心轮转轴不在中心的盘或轮，能导致周而复始的运动

It is shown from the results that the acting force and vibrating acceleration are increased due to its axle load, however, the dynamics interaction between 25 t load wagon and the turnout can be improved by the rubber stack in its axle box, especially in the index such as derailment coefficient, reduction rate of wheel load, opening size of tongue rail and point rail, which is almost equal to the dynamics of 21 t axle load wagon.

结果表明尽管轮轨力和振动加速度因轴重增加而相应增大，但由于25t轴重货车在轴箱处采用橡胶堆，使它与道岔之间的动态相互作用有所改善，尤其是脱轨系数、减载率、尖轨和心轨前端开口量等指标上，与21t轴重货车引起的系统振动值基本一致。

The truck cast steel three big piece type bogie is easy to maintain. But since the grate weight under spring and the large operation strength during running, it is difficult for the bogie to keep the positive position. The critical speed of the snaking motion is low, which is inapplicable for high speed running. The other type of truck bogie is H type integrative truss. Its structure is complicate relatively, which is not easy to manufacture and maintain. But it can keep the positive position of the bogie preferably. And because it is adopted the structure of axle box one series elastic suspend, the weight under spring reduces. Which achieve the effective control to wheel sets and improve the running quality of the bogie distinctly.

货车铸钢三大件式转向架便于制造维修，但因其簧下质量大，在运行中轮轨作用力大，转向架难以保持正位，蛇行运动临界速度低，不适用于高速运行；货车转向架的另一种形式是"H"型构架一体式，结构较为复杂，不便于制造和检修，但它能够较好地保持转向架的正位，而且由于采用了轴箱一系弹性悬挂结构，降低了簧下质量，实现了对轮对的有效控制，明显地改善了转向架的运行品质。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
