The survey report. Pupils myopia Now the primary myopia rate rise sharply, many students have become "four-eyes flogs", in order to let students attention, I myopia pupils myopia, launched a probe conditions as follows: The pupils, high myopia rate 22.78% show ascendant trend.

小学生近视的调查报告现在小学生的近视率直线上升，许多同学都成了"四眼田鸡"，为了让同学们重视近视的危害，我对小学生近视状况展开了调查，情况如下：目前全国小学生近视率高达22.78%，呈逐年上升趋势。

Numerical simulation by Matlab for the new hypocycloid energy transformation mechanisms was done by means of the four-order Runge-kutta's method. The result shows that the simple harmonic and rectilinear motion of piston in the new mechanism make the engine working more stable. The peak acceleration is around 25% lower in the new mechanism than that in the conventional slider-crank mechanism. And the output speed is much higher at the same identical mean effective pressure and same load torque. And then the output power of the engine is improved.

基于四阶Runge-Kutta法，运用MATLAB进行了仿真验证，结果表明，新型内摆线能量转换机构的活塞做完全简谐直线运动，运动更加平稳；活塞加速度峰值比传统曲柄滑块机构小25%；在相同的气缸平均等效压力和负载转矩下，具有较高的输出转速，提高了内燃机的输出功率。
