In this study,a HPLC-ESI (-) MS/MS methodology is developed for the residue determination of 3,4,5-Tribromosalicylanilide.The sample was extracted by the acetonitrile after and operating for decontamination by n-Hexane.The chromatographic column was Waters Atlantics C18,the mobile phase was a mixture of water-acetic acid(0.1%) and acetonitrile.Samples were detected by a gradient elution flowing with a ESI negative mode detector at MRM:m/z 447.80/79.00.m/z 447.80/168.90.m/z 447.80/250.70.In the line of quality assurance,When fortified with 3,4,5-Tribromosalicylanilide the sample,the stated LOQ of 3,4,5-Tribromosalicylanilide residues in the negative sample was at the level of 0.5~2 μg/kg.The response for 3,4,5-Tribromosalicylanilide was linear in the range of 0.5~50.0 g/L,the correlation coefficient is excellent 0.9991.

针对单个正弦信号采用具有二维状态变量和一维参数变量的三维自适应陷波滤波器。通过单个正弦信号的基波频率估计算法，获得了它的状态变量和输出频率特性及各正弦分量幅值的准确估计。在平均方法的基础上用李雅普诺夫方法对基波频率更新法则的稳定性进行了分析，使其由渐进稳定推广到了全局稳定。采用四阶龙格-库塔方法实现该正弦信号的离散化，定义各参数变量，给出了离散化过程的微分方程组及流程图。并通过Matlab编程仿真
带式输送机启动是一个加速过程，输送带在启动过程中产生黏弹性变形而产生动张力，如果直接启动或启动时间短，加速度就会变大，相应的输送带黏弹性变形就增大，动张力也变大，对输送机的元部件产生较大的冲击，从而影响输送机系统的稳定性和使用寿命。因此，大型带式输送机的启动问题是一个重要的技术问题。首先通过有限元法建立大型带式输送机的数学模型，然后着重对控制器进行研究，利用单神经元智能控制理论来实现带式输送机启动
