The algebraic Bethe ansatz for the Izergin–Korepin model with open boundary conditions

We present the procedure of exactly solving the Izergin–Korepin model with open boundary conditions by using the algebraic Bethe ansatz, which include constructing the multi-particle state and achieving the eigenvalue of the transfer matrix and corresponding Bethe equations. We give a proof about our conclusions on the multi-particle state based on an assumption. When the model is U_q(su(2)) quantum invariant, our results agree with that obtained by analytic Bethe ansatz method.

采用空心阴极放电等离子体化学气相沉积方法制备a-CH薄膜

 研究了不同衬底-阴极距离、直流电压和H₂流量对a-CH薄膜沉积速率的影响。结果表明：衬底-阴极距离必须大于0.5cm，随着该距离的增加，薄膜的沉积速率减少；直流电压达550V时沉积速率最大；随着H2含量的增加，CH₄含量相对减少，沉积速率随之降低。用AFM观察了以该方法制得的448.4nm CH薄膜的表面形貌，表面粗糙度约为10nm。最后测出了不同条件下CH薄膜的UV-VIS谱，由此可以计算得到薄膜的禁带宽度及折射率。     

爆磁压缩发生器通过脉冲变压器对脉冲形成线充电的理论分析

 将爆磁压缩等效为电流源的方法，对爆磁压缩发生器通过脉冲变压器对脉冲形成线充电进行了理论分析，得出爆磁压缩发生器在负载上产生电流波形（简称负载电流）为直线情况和任意电流波形情况下充电电流和充电电压的表达式。分析表明变压器耦合互感与负载电流随时间变化增长率是脉冲形成线充电的两个重要参数，脉冲形成线第一个充电电压峰值与变压器的耦合互感和负载电流波形斜率成正比，负载电流波形斜率的变化可以改变充电电压峰值的时间，斜率不断增加可以延长第一个充电电压峰值时间，从而可能增加充电电压的幅值，提高爆磁压缩发生器能量的利用效率。
