简介：穿孔面板结构有一个宽潜力在在水下应用程序。然而，直到现在，几乎没有很少相关研究。声学的阻抗一在水下穿孔面板为空气基于理论被获得穿孔面板声音absorption.In这个论文声音传播特征在水下穿孔面板结构被转移矩阵方法理论上分析。为正常发生声音传播系数的一个公式被给。在声学的传播系数上有效果的主要因素被数字模拟分析。自己做的穿孔面板结构被四传感器的转移功能method.The在一个看台波浪试管测试试验性的结果被数字方法很好与结果一致获得，它证明理论分析是正确的。这篇论文为设计提供了理论、试验性的底在水下穿孔面板结构。

简介：AbstractAntimicrobial resistance leads to failure of clinical antimicrobial therapy, and has raised urgent global public health concern. Humans can acquire antimicrobial resistance from drugs through the food chain or the environment (contaminated water, air, soil, or manure). While antimicrobials have been regular supplements in animal feed that maintain health and improve productivity of livestock, their over-use in feeding forage has led to a rise in antibacterial resistance. This review summarizes the current use of antimicrobials in livestock, the harmful effects of antimicrobial resistance, and the comprehensive combat measures.
