摘要：Energetic particle radiation diagnoses mainly detect the particles(such as neutrons,gamma rays,hard X-rays,and escaping electrons)that are radiated in the discharge process of the experimental advanced superconducting tokamak device to characterize the operating state of the plasma in real *** upgrading of these diagnoses requires new instruments based on national(here,“national”means developed and produced by a Chinese company)core chips and open-source software with advanced digitization,a high sampling rate,and a high time *** new spectroscopy system designed in this study adopts the national field-programmable gate array(FPGA)and an analog-to-digital converter as the core chip,and it is developed using Qt on *** communication between the FPGA and embedded controller occurs via a high-speed peripheral component interconnect eXtension for instrument express protocol with a direct memory access *** this basis,the time resolution of the system is improved from 2 to 1 ms,the maximum channel address is increased to 4096,and the sampling rate is increased from 10 to 80 *** experiments of the spectroscopy system with 152Eu and 137Cs sources demonstrate that the best energy resolution is 0.27%and the measurement error is less than±0.5 keV.

摘要：为探究α-甘露聚糖对保育仔猪免疫力与生产性能的影响,选用保育仔猪40头,采用单因素试验设计,随机分为试验组和对照组,每组20头,公母各半。对照组饲喂保育猪饲料,试验组饲料按500 g/kg添加α-甘露聚糖饲喂至试验结束。40头受试猪于14、28、37、47日龄,分别肌肉注射猪繁殖与呼吸综合征、猪瘟、猪伪狂犬病活疫苗各1头份。试验至54日龄,每组随机抽公母仔猪各3头宰杀,采集肝、胸腺、脾等器官计算器官指数,制作组织切片,光镜检查。于75日龄每组抽样采血7头,ELISA测定3种病原的血清抗体水平。结果显示,试验组全程成活率比对照组提高5%,饲料利用率提高11.49%,试验组54日龄平均体重比对照组高3.11 kg,期末平均日增重高66.26 g,增重部分与投入品的投入产出比为1∶10.55(P<0.05)。试验组肝、胸腺、脾等器官指数均高于对照组(P<0.01)。75日龄,试验组血清抗体阳性率均高于对照组;与对照组相比,试验组肝脏肝小叶结构致密,肝板、肝索形态清晰,肝细胞核清晰,胸腺结构紧凑,发育充分。脾脏,皮质部和髓质部结构致密,白髓和红髓分界清晰,脾小结和弥散性淋巴组织发达。结果表明在保育期内饲喂α-甘露聚糖能显著改善仔猪免疫器官和内脏器官发育,提高保育猪对接种疫苗的免疫应答能力,增强疫苗的免疫效果,给后期肥育和猪的快速生长奠定了良好的基础。

摘要：苗族是我国古老的少数民族之一,经过长期的发展演变,形成其独树一帜、绚丽多彩的民族服饰艺术风格。由于苗族主要分布在偏远封闭的山区,其服饰文化基本保留了原始的风貌,能够反映出苗族的历史、社会、文化等形态。对苗族服饰设计中的历史记忆符号进行研究有助于探索服饰背后的历史文化表征。文章首先阐述苗族服饰的类型,其次分析苗族服饰设计中对历史记忆、伦理道德、社会身份、审美意识的表现,最后探讨其在身份识别、社会交流、文字记载、文化审美等方面的重要功能。

摘要：设计了一款采用波前编码技术的虹膜采集光学系统,以实现大景深、自然非约束状态下的成像.以传统的光学系统评价指标斯特利尔比和能量集中度作为波前编码系统的成像特征,利用ZEMAX软件对波前编码系统进行设计,权衡了离焦不敏感性和图像可恢复性.比较了带有立方相位编码板和带有修正项的立方相位编码板的虹膜采集系统以及传统系统的焦深延拓效果.发现采用立方相位编码板的虹膜采集光学系统的焦深延拓效果最佳,其焦深是传统系统的8倍.该系统增大了虹膜采集的距离,对于自然状态虹膜成像系统设计有一定的参考价值.
