Aiming at the physical model inapplicability of flash method to measure thermal diffusivity of semi-transparentmaterials, a new physical model was proposed. In the model, according to the permeance of materials, the pulse laserabsorption of materials is of exponential type, and the authors establish a relevant differential equation and get a analyticalform.

针对传统的闪光法在物理模型上不适于用来测试半透光物质热扩散率的问题，提出了一个新的物理模型，该模型根据物质的透光性，确定样品对脉冲激光的吸收为指数型，建立了相应的微分方程并求得其解析解。

The Pd-Cu/C catalysts were shown to have the face centered cubic crystal structure. This could indicate that the addition of Cu shortened the Pd-Pd distances in the crystal lattice, and therefore –HO(subscript 2ads) and O-O could be better adsorbed on the surface of the catalyst. When NaBH4 was used as the reducing agent, and the atomic ratio of Pd to Cu was 3:1, the resulting catalysts had an average particle size of 3. 4nm and showed the best catalytic performance. The electrochemical active surface are a of Pd3Cu/C was 38.9m^2/gPd and the oxidation reduction reaction activity of the Pd3Cu/C catalyst was much higher than that of the Pd/C catalyst. The electrochemical activity of the Pd3Cu/C catalyst was comparable to that of a commercial Pt/C catalyst.

结果表明：催化剂中Pd与Cu的物质的量之比与预设值相近，Pd和Cu基本被全部还原；Pd-Cu/C催化剂为面心立方结构，元素铜的加入使催化剂的Pd-Pd间距缩小，从而HO(下标 2 ads)和OO键能更好地吸附在催化剂金属表面；当采用NaBH4为还原剂，Pd与Cu物质的量比为3：1时，催化剂(Pd3Cu/C)的平均粒径为3.4 nm，催化剂的催化性能最好，电化学活性表面积EAS达到38.9平方公尺/gPd，电化学性能较Pd/C催化剂有很大提高，接近Pt/C商用催化剂。
