中国核科技报告 2000年第S3期 33-41页

作者： Liu jianfeng zhao Weijuan (Department of Physics, Zhengzhou University, 450052)

The aim of this paper is to theoretically explain the abnormal protuberances near and above 5.5 MeV in the gamma spectra of the (n,γ) reactions of the nuclei within the nuclear mass regions from 110 to 140 and from 180 to 210, respectively. Supposing that in the primary and cascade gamma de-excitation processes of the compound nucleus, in addition to the giant dipole resonance model, there exist the de-excitation processes of the excited states of ~6He, ~6Li, ~6Be, ~7Li and ~7Be particle cliques, for which the gamma-ray strength function was developed. The (n,γ)reaction cross sections and the gamma energy spectra at the neutron incident energies from 0.01 MeV to 3 MeV forAu were calculated and the results are in better coincidence with the experimental data. Especially for the gamma energy spectra, the abnormal protuberances near and above 5.5 MeV were reproduced very well.

为研究不同AP体积分数及AP颗粒尺寸在亚大气压环境下对AP/HTPB底排药剂的燃烧特性影响,建立了AP/HTPB二维微尺度物理模型,采用BDP燃烧模型来模拟气相燃烧。在亚大气压环境下对AP/HTPB燃烧进行数值模拟,分析了AP体积分数在0.76~0.88以及AP颗粒半径分别为40μm,80μm,120μm时对AP/HTPB燃烧特性影响。结果表明:AP半径为80μm时,第一步反应的核心放热区面积随着AP体积分数增加而减小,AP体积分数在0.84时燃速达到最大。AP含量不同将导致燃面形状发生变化,AP体积分数增大,HTPB将出现明显凹陷;在同一AP体积分数时,AP颗粒尺寸越大,燃速越慢。AP颗粒尺寸不同,燃速达到最大值时AP的体积分数也不同,AP颗粒半径为40μm时,燃速达到最大值时AP的体积分数为0.86,AP颗粒半径为120μm时,燃速达到最大值时AP的体积分数为0.78,随着AP颗粒半径的增大,在对应半径下达到最大燃速时需要的AP含量下降。

带数值耗散的算法因其能有效过滤虚假高频响应的影响而备受关注。基于离散控制理论Z变换,提出一类带数值耗散的结构动力学显式算法。该算法采用CR法的速度和位移递推式,满足零振幅衰减率,且对线性系统和非线性刚度软化系统为无条件稳定,对刚度硬化系统则是条件稳定的;该算法由单个参数ρ控制数值耗散能力。通过对振幅衰减和周期延长的理论分析表明,系数a可调节算法的精度和非线性稳定区间,给出精度最优时系数的取值。对特定的系数取值该算法可转变为CR法。通过算例对线性系统和非线性系统的分析验证了新算法具有良好的精度、稳定性和数值耗散,表明新算法是正确有效的。

提出一种应用于并联有源电力滤波器的同步坐标系下空间矢量滞环电流控制新方法。该方法提出在同步坐标系下将输出电压空间矢量分布图由传统的6区域等分为12个区域,并从负载电流中分离出基波量作为参考值,以网侧电流为控制对象,对直流量进行滞环跟踪控制;采用两个三电平滞环比较器和一个两电平滞环比较器组成的新型两级滞环比较器,确保选择最合适的输出电压矢量。与传统静止坐标系滞环控制相比,本文提出方法可避免输出电压矢量选择冗余且复杂的问题,电流控制精度高、补偿效果好。同时还分析了在输出电流完全可控情况下本文提出方法所需的最低直流侧电压,并据此选择合适的直流电压,得到最优的补偿效果。最后通过全面的仿真和实验,分析和验证本文所提方法的正确性和可行性。
