提高功率的

Five minutes is the optimal irradiation time for ALA-PDT by Xe lamp under the same irradiation conditions. Irradiation injury caused by the light alone was slight, but the destruction rate of ALA-PDT was very high. Conclusion: Xe lamp's action spectrum is wider and it's power is higher, so it's better than 532 nm laser for ALA-PDT.

结果：532 nm连续激光和脉冲激光对K562细胞的ALA-PDT抑制率均较低，增加光剂量也不能有效提高ALA-PDT的抑制率；氙灯在功率密度为350 mW/平方公分、光照5 min时就能达到最佳的光剂量，此时单纯光照对K562细胞的光损伤作用很小且ALA-PDT效率很高。

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.
