According to the property of EBB, scanning electron beam was considered as plane heat source instead of spot heat source in this paper. Aiming at the problems to measure the real-time temperature and residual stress of radiator difficultly at high temperature, the two-dimensional finite element models were established. Based on the thermal elastic-plasticity, the temperature fields and stress fields of EBB 6139T and 6204T radiator by two kinds of process were simulated by the software of ANSYS. It is of great value and significance to guide actual production.

本文根据电子束钎焊的特点，将电子束点热源转化为扫描加热时的面热源，针对散热器高温下温度实时测量和残余应力实测困难这一问题，建立了二维有限元模型，以热—弹塑性理论为基础，利用ANSYS软件对6139T和6204T散热器分别按两种电子束钎焊工艺钎焊的温度场和应力场进行了数值模拟，对于指导实际的生产具有重要的价值和意义。

The polarization curve is not sufficient for a reliable and unique validation of a PEMFC model since different parameters can lead to an identical polarization curve. A three-step validation approach is proposed for a complete and unique validation. These three steps are:(1) validated by the global polarization curve,(2) validated by the local current density distribution curve, and (3) validated by the cathode over-potential and anode over-potential versus current density curve. The results from the comparison of four flow-fields show that the PEMFC performance of the flow-fields decreases in order by interdigitated, metal foam, pin-type and parallel.

通过PEMFC参数敏感性研究发现，PEMFC性能受多种参数的影响，这些参数可分为非敏感性参数、敏感性参数和高敏感性参数；与阳极侧参数相比，PEMFC性能对阴极侧的参数更敏感；不同参数值的组合可以得到几乎完全相同的极化曲线，因此电池的极化曲线不足以用于验证数学模型的唯一性与可靠性；为验证PEMFC数学模型的唯一性与可靠性，提出了模型验证的三步法：极化曲线验证、局部电流密度验证和阳极总过电位与阴极总过电位验证。

The above multiple changes will produce 2 kinds ofwaves, Matter waves and mechanical wavesthat spread at the same time. Because the electromagnetic wave is amatter wave, it is the medium. Since the multiple exchanges of theelectrons state can be regarded as electrical vibration, and thevibrated electrons have magnetic fields and electrical fields at the same time, the electromagnetic wave will be produced. Then, because the electron itselfis a matter micro particle, it can producemechanical waves which can propagate outside withelectrical magnetic waves.

这种状态改变的多次往复，就会产生两种波，一种物质波，即电磁波；一种机械波，并且这种机械波是以同次产生的电磁波为媒质进行传播的，，这是因为本种状态的多次往复，可以看作是一种电子振动，振动的电子同时具有磁场和电场，所以能够产生电磁波，又因为电子本身是一个物质微粒所以他能够产生机械波，并且是横波，并随电磁波进行向外传播。
